You already have a primary mortgage, and you're pricing out a second property: a vacation house, a future retirement spot, or somewhere to stay part of the year. The math feels close. Then you find out about the rate premium, the April 2022 pricing change nobody mentioned, and what insurance actually costs in coastal markets right now.
Or you might not be shopping for a second home at all. Maybe you're buying a new primary residence and planning to convert your current home to a rental. If that's you, there's a section below that addresses it directly.
Two policy changes define this market in 2026:
- Fannie Mae's April 1, 2022, loan-level price adjustments (LLPA) update repriced second-home loans much closer to investment properties; four years later, it's still why moving from 20% to 25–30% down changes your rate tier meaningfully. LLPAs are upfront fee adjustments tied to the risk profile of the loan — your credit score, LTV ratio, and property type — that the lender either charges as points at closing or rolls into your rate.
- The November 16, 2025 Selling Guide update (Announcement SEL-2025-09) removed the third-party FICO minimum from Desktop Underwriter.[1]
We'll cover the rate premium in dollars, the three-way property classification, and the hidden costs that are blowing up more second-home deals in 2026 than the mortgage rate itself.
Quick answer: What you need to buy a second home in 2026
One terminology point first: a second home mortgage is a mortgage on a property you'll own and occupy part of the year. It's not a "second mortgage" — that's a home equity loan or HELOC against your current home.
Current rates (spring 2026): The 30-year fixed primary rate is 6.53% for the week of May 28, 2026.[2]
The average second-home rate for a 720 FICO borrower is 7.60% as of May 2026.[3]
Down payment minimum: 10% for a conforming conventional home loan.[4] But 25–30% unlocks the best LLPA pricing tier.
Credit: As of November 16, 2025, Fannie Mae's Desktop Underwriter no longer requires a minimum third-party FICO score; most lenders still apply their own overlays of 680–720+.[1]
What counts as a 'second home' and what doesn't
"Second home" is a mortgage classification, not just casual terminology. Fannie Mae defines it with specific eligibility requirements that differ from both primary-residence and investment-property loans, and from the IRS's own definition. That mismatch is where most buyers get tripped up.
Primary residence vs. second home vs. investment property
Here's how lenders sort these three categories, using Fannie Mae's guidelines as the framework:
| Factor | Primary Residence | Second Home | Investment Property |
|---|---|---|---|
| Min. down payment | 3% (conventional), 3.5% (FHA) | 10% | 15–25% |
| Best pricing tier | 5–20% down | 25–30% down | 25%+ down |
| Credit (typical lender overlay, post-Nov. 2025) | 620+ | 680–720+ | 700–720+ |
| DTI ceiling | Up to 45–50% with compensating factors | 43–45% | 43–45%, varies |
| Rate premium vs. primary | None | +0.25–0.50% | +0.50–0.75% |
| Occupancy requirement | Owner occupies year-round | Owner occupies "some portion" of the year; one unit; suitable for year-round use | No owner-occupancy required |
| Rental income counts for qualifying? | Limited | No | Yes, with restrictions |
| FHA/VA/USDA eligible? | Yes | Generally no | No |
Source: Fannie Mae[5] [6]
Fannie Mae allows occasional rental of a true second home; it just doesn't allow using that rental income to qualify for the loan.[6] Lenders verify compliance at underwriting and after closing: utility accounts, mail delivery, insurance designation, and IRS filings all get cross-referenced. Misrepresenting your intended occupancy is federal mortgage fraud under 18 U.S.C. §1014 and gives the lender grounds to accelerate the loan under the due-on-sale clause — meaning they can demand the full outstanding balance immediately.[7]
George Dimov, CPA, Founder & CEO of Dimov Tax, addresses the most common workaround he sees: "Fannie Mae will not lend to an LLC for a second-home loan. Buyers hear this idea on TikTok and don't realize it's for a different type of loan, not a 30-year fixed at second-home rates. The 'put it in my spouse's name' plan is what I actually see. This is fraud if the spouse signs a statement they do not intend to follow. When lenders find out, they demand payment under the due-on-sale clause. It is also a crime under 18 U.S.C. §1014."
Are you sure this is a second home? Three scenarios that aren't
Scenario A: You're buying a new primary and converting your current home to a rental. This is a primary-residence mortgage on the new property, not a second-home loan. Most lenders allow conversion of the existing home to a rental without reclassification if you've lived in it 12+ months.
Scenario B: You plan to rent the property year-round. That's an investment property with a different rate, different down payment, and different qualification rules.
Scenario C: You plan to use it four weeks a year and rent it 40 weeks. Fannie Mae is fine with this occupancy pattern. The IRS is not. See the "two-test problem" in the tax section below.
Second home mortgage requirements
Down payment
The Fannie Mae and Freddie Mac down payment floor for a second home on a conforming conventional loan is 10%.[4] Below 20%, you'll pay private mortgage insurance (PMI), which typically runs 0.5–1.5% of the loan amount per year.[8]
At 25–30%, you cross into a better LLPA pricing tier. Putting more down doesn't just lower the monthly payment; it can lower your rate by 0.125–0.25% by moving you into a more favorable position on the Fannie Mae pricing matrix.[9]
Credit score
As of November 16, 2025, Fannie Mae's Desktop Underwriter no longer has a minimum credit score requirement; its proprietary credit risk assessment now drives eligibility.[1]
In practice, most lenders still apply their own overlays. Expect 680+ as a working floor for second-home approval, and 720+ to land in the best pricing tier. Anyone citing a "640 minimum" is using guidance that predates November 2025.
DTI ceiling
The typical ceiling is 43–45% for a second home; some Fannie Mae programs allow up to 50% with strong compensating factors.[9] Your existing primary mortgage counts in this calculation, which is where the math gets tighter than buyers expect.
Cash reserves
Plan on 2–6 months of mortgage payments in reserves.[10] Coastal and high-insurance markets often push that number higher. Reserves come up less often than credit or down payment in conversations with buyers, and they derail more deals than either.
Kyle Bass, Production Manager at Refi.com, notes that the reserve bar has risen: "The biggest shift we've seen entering 2026 is that lenders are scrutinizing payment shock much more closely than they did two years ago. It's no longer enough to show that a borrower qualifies on paper. Underwriters want to see that the borrower can absorb the new payment comfortably if rates move. Liquidity and reserve documentation have become significantly more important than they were during the 2020–2022 approval environment."
Documentation
Standard income documentation applies: W-2 for salaried borrowers, two years of tax returns for self-employed. Beyond that, lenders typically verify that the property is suitable for year-round occupancy, is not subject to a mandatory rental pool or timeshare arrangement, and is controlled exclusively by the borrower.[5] You'll sign a written intent-of-occupancy statement — signing falsely can constitute fraud. Consider getting prequalified with a lender before assuming you don't qualify.
Second home mortgage rates
The current rate premium
The 30-year fixed primary rate is 6.53% as of the week of May 28, 2026.[2] The average second-home rate for a 720 FICO borrower sits at 7.60% as of May 2026.[3] Investment-property rates run another 0.25% higher, at roughly 0.50–0.75% above primary, which is useful context when you're trying to stay on the right side of the occupancy line.
The math on a $495,000 second home
Second-home originations hit their lowest share on record in 2024: 86,604 loans, representing 2.6% of all mortgages, down 5% year over year.[11] The 2024 median purchase price from that dataset is $495,000. Here's what the principal-and-interest payment looks like across four down payment levels:
| Down Payment | Down Amount | Loan Amount | Approx. Monthly P&I (30yr, 7.60%) | Notes |
|---|---|---|---|---|
| 10% | $49,500 | $445,500 | ~$3,146 | PMI required; least favorable LLPA tier |
| 20% | $99,000 | $396,000 | ~$2,796 | No PMI; mid LLPA tier |
| 25% | $123,750 | $371,250 | ~$2,621 | Best LLPA tier; rate may be 0.125–0.25% lower |
| 30% | $148,500 | $346,500 | ~$2,447 | Best tier; lender overlay relief |
P&I figures are approximations at 7.60%. At 25–30% down, the actual rate will often be lower, reducing the payment further. Insurance, property tax, HOA, and reserves are not included and add materially to the carrying cost — see the hidden-costs section before treating the P&I as your total payment.
Matt Brown, a luxury real estate advisor with William Raveis Real Estate in Naples, Florida, has seen the down-payment tier shift play out in real dollars: "The smallest change that creates meaningful savings is increasing the down payment from 20% to 30%, which often drops pricing another 0.125–0.25% and eliminates some lender overlays. I had a client reduce their rate from 7.25% to 6.875% by increasing their down payment from $400K to $600K on a $2M Naples property, saving $7,500 a year in interest."
Why second-home rates went up in April 2022
Fannie Mae adjusted its LLPA matrix effective April 1, 2022, repricing second-home loans much closer to investment-property loans.[9] Before April 2022, second homes priced similarly to primary residences. After April 2022, they price closer to investment properties. That's the structural reason the rate premium exists today.
The practical lever: moving from 20% to 25–30% down typically shifts you into a better LLPA tier and shaves 0.125–0.25% off the rate.
How to finance a second home: Conventional, HELOC, cash-out, and recast
Financing options at a glance
Most second-home financing falls into four buckets. The right one depends on how much equity you have in your primary home, your comfort with variable rates, and the property type.
| Option | Best for | Rate vs. 30yr primary | Pros | Cons |
|---|---|---|---|---|
| Conventional second-home loan | Standard purchase; 10% min. down | +0.25–0.50% | Predictable; broadly available | LLPA pricing tiers; 10% floor |
| HELOC on primary | Buyers with equity who want flexibility | Variable, indexed to prime | Tap equity without a full refi; revolving credit | Variable rate; secured by primary home |
| Cash-out refi on primary | Buyers with a higher-rate primary or significant revolving debt to consolidate | Adds to current primary balance at new rate | Single fixed payment; consolidates debt | Gives up your existing primary rate |
| Portfolio/non-conforming | Properties or borrowers outside Fannie/Freddie guidelines | Materially higher | Flexible underwriting | Pricier; less consumer protection |
Should you tap home equity instead of a second mortgage?
If you're sitting on a primary mortgage at 3–4%, this question matters a lot. The conventional answer — "just get a HELOC" — glosses over the math that actually drives the decision.
Bass walks through how he frames it for clients holding low-rate first mortgages: "Here is the actual math side by side. Keep a 3.25% first plus an 8% home equity loan: annual interest on $300K at 3.25% is $9,750; annual interest on $100K at 8% is $8,000; total interest is $17,750 on $400K, or a blended rate of about 4.44%. Cash-out refi at 6.75%: annual interest on $400K is $27,000. That is $9,250 more per year in interest costs, roughly $770 per month. For most homeowners in this position, preserving the low first mortgage and adding a second lien is the obvious move unless there is a compelling reason to consolidate."
The math starts to flip when: the second lien is very large relative to the first mortgage balance; the home equity loan rate is elevated (9.5% or higher) due to weaker credit or high combined LTV; you're carrying substantial revolving debt and want to consolidate; or your existing first mortgage rate is already above 5.5–6%.
Bass frames the product decision around three questions: How long do you expect to carry this debt? Do you need flexibility in how and when you draw funds, or do you need payment predictability? And are you protecting an existing low first-mortgage rate, or is that already gone? Those three answers, he says, usually point toward the right structure quickly.
One more consideration if you're tapping equity for home improvements: the IRS Pub 936 substantial improvement test determines whether HELOC or home equity loan interest is deductible. Interest is deductible when the proceeds are used to buy, build, or substantially improve the home that secures the loan — a full kitchen remodel, a room addition, or a new HVAC system generally qualifies. Using the same HELOC to pay off credit cards or fund a vacation does not, even though the loan is secured by the home. Bass recommends borrowers consult a CPA or tax advisor to confirm how their specific use of funds is treated before assuming deductibility.
The recast strategy
Less discussed than a HELOC or cash-out refi, the recast is worth understanding before you close. A recast lets you make a large lump-sum principal payment after closing and have the lender re-amortize the loan at your existing rate — lowering the monthly payment without a full refinancing, and without giving up the rate you locked.
Typical cost: $250–500, compared with several thousand dollars for a refi.
Brett Johnson, owner of New Era Home Buyers and a licensed real estate agent and investor in Colorado, explains the appeal: "Many buyers don't realize they can make a large payment against the principal after closing and have the lender re-amortize the loan to lower their monthly payment — without refinancing. For homes that don't fit standard Fannie Mae guidelines, portfolio lenders or portfolio-loan products are another workaround, though they typically come with higher interest rates than conforming loans."
A recast makes particular sense if you close with 10% down to capture the deal, then expect a windfall in the next 6–12 months (bonus, asset sale, primary-home sale) that would bring you to 25%+ effective down. Not every lender or loan type allows recasting; ask before you close.
Government-backed loans (FHA, VA, USDA) and why they generally don't apply
FHA loans are generally ineligible for second homes, with narrow exceptions for relocation (typically 50+ miles from an existing FHA-financed home) or for a family member's principal residence.[12] VA loans are intended for primary-residence occupancy.[12] USDA loans are primary-residence only.[13] For most second-home buyers, the answer is a conventional loan, a HELOC, or a cash-out refi.
The tax rules every second-home buyer should know
Tax treatment for a second home involves four separate rules that interact with each other. Missing any one of them can cost real money.
The $750K mortgage interest deduction cap
For mortgages taken out after December 15, 2017, you can deduct interest on up to $750,000 of combined acquisition debt across your primary and second home ($375,000 if married filing separately). Mortgages originated before December 15, 2017, are grandfathered at the $1,000,000 cap.[14] If your combined mortgage debt exceeds $750,000, you can deduct interest only on the portion up to that threshold.
The SALT cap
The state and local tax (SALT) deduction is capped at $10,000 per year through tax year 2025 under the Tax Cuts and Jobs Act.[15]The 2026 status is subject to pending legislation.
Property taxes on your second home count against the same $10,000 cap as your primary home's property taxes. Many buyers don't realize this until they file.
The 14-day-or-10% personal use rule
If you rent out your second home, IRS treatment turns on how much you use it personally. A property is a "residence" for tax purposes if personal use exceeds the greater of 14 days or 10% of the days rented at fair market value.[15] There's also a 15-day safe harbor: rental income is tax-free if you rent the property fewer than 15 days in a year, but related rental expenses aren't deductible, either.[15]
The capital gains exclusion
When you sell, up to $250,000 of capital gains ($500,000 if married filing jointly) can be excluded from income tax, but only if you've owned and used the property as your principal residence for at least two of the last five years before the sale.[16] A second home doesn't qualify unless you convert it to your primary residence first. Converting two years before selling can mean a significant tax saving — plan accordingly.
The two-test problem
The Fannie Mae "second home" definition and the IRS "residence" definition are two separate tests, and they don't agree.
George Dimov, CPA, explains the collision: "The common mistake I see is when a buyer uses a property for 4 weeks and rents it out for 40 weeks. They think, 'I said it was a home when I bought it so it must be a second home on my taxes too.' On their tax return, 28 personal days against 280 rental days means it is an investment property. They lose the personal residence treatment. Their mortgage interest gets split between Schedule A and Schedule E. Fannie Mae is okay with their use pattern. The IRS is not."
Both tests apply independently. Satisfying one doesn't mean you've satisfied the other.
Working with a buyer's agent on a second home
The August 17, 2024 NAR settlement requires a written buyer-agent agreement before any showing.[17] For second-home buyers who tour during a 48-hour scouting trip in an unfamiliar market, this changes the logistics: sign the agreement before you tour, not after.
Buyer-broker compensation is no longer published on MLS and is now negotiated separately. Sellers can still cover some or all of the buyer-side commission as a purchase-offer term, but it's not built into the transaction automatically anymore.[17]
Three things to nail down when shopping out-of-area:
- Scope: Is the agreement limited to a specific property, or does it cover an entire MLS area? Time-limited and geographically scoped agreements give you more flexibility if your search spans multiple markets.
- Duration: 60–90 days is common for out-of-area searches. Open-ended exclusive agreements can create problems if your timeline runs longer than expected.
- Compensation: Flat fee, percentage, or hourly; whether the seller is expected to contribute. Per Clever's 2026 commission survey of approximately 533 agents, 2.82% is the typical buyer-side commission post-settlement — a useful reference for what's reasonable to negotiate.
The hidden costs that blow up second-home budgets
The mortgage rate gets most of the attention. In 2026, it probably shouldn't.
Insurance
Second-home insurance premiums typically run 60–100%+ above primary-home premiums, because the property is unoccupied for stretches, which insurers price as elevated risk.[18] In coastal and disaster-prone markets, the gap is considerably wider.
John Espenschied, owner of Insurance Brokers Group with 25 years in the industry, puts it plainly: "In 2026, the second-home mortgage market looks fine on paper, but the real choke point is insurance. For many of my second-home clients, premiums on a beach or mountain place are now two to three times what they pay on their primary home, even before you layer on wind, flood, or wildfire coverage. Buyers used to shop insurance a week before closing; now I'm telling them to get quotes before they fall in love with the house. In some Florida and Gulf Coast ZIP codes, we've seen homeowners premiums jump 40–50% in just a few years — so waiting to the end is how people blow up their debt-to-income ratios at the last minute." — John Espenschied, Owner, Insurance Brokers Group
Wind and flood coverage are typically separate policies stacked on top of base homeowners coverage, so "the insurance bill" on a coastal second home is often three line items, not one.[18] Matt Brown has seen the flood version of this shock firsthand: "I had buyers purchasing a $3.5M bayfront property discover flood insurance would cost $18,000 annually — versus the $1,200 they estimated — when FEMA updated flood maps mid-transaction. The buyers had no way to predict this during application because flood determinations happen at the appraisal stage. Now I require flood insurance estimates during pre-approval for any property within a mile of water."
Property tax: No homestead exemption, plus reassessment to purchase price
Homestead exemptions and equivalent owner-occupant tax relief do not apply to second homes. That alone can effectively double the property tax versus a primary-residence buyer next door.
What catches buyers off guard is that most vacation markets reassess the property to the purchase price the year after closing. The seller's tax bill is not your tax bill.
Dimov's client example: "I had a client in Florida whose annual taxes jumped from $4,200 to $14,800 in year two. Insurance gets a lot of attention because it doubles quickly. Property taxes are slower and worse because they add up over time. The fix is simple: ask the county assessor for the rate, multiply by your purchase price, and use that number — not the seller's bill."
Maintenance and vacancy reserves
Budget for roughly one month of vacancy each year and a few hundred dollars monthly in repair reserves. Those numbers aren't dramatic in isolation; accumulated over a year, they represent a meaningful carrying cost that rarely appears in buyers' initial projections. For major capital expenditures, the Remodeling 2024 Cost vs. Value Report provides regional benchmarks.[8]
Property management
If you're renting occasionally, a property manager will typically take 8–12% of monthly rent. A manager handles logistics, not surprises: turnover, HOA issues, and repair decisions still come back to you.
How to apply for a second home mortgage in 5 steps
By this point, you have the numbers. Here's the sequence that matters:
- Pull your credit and address obvious errors at AnnualCreditReport.com, 60–90 days before applying. Lenders run a hard pull at application; knowing where you stand first gives you time to resolve anything meaningful.
- Get insurance quotes before making an offer. Premium shocks blow up DTI calculations at the last minute. For any property near water, get flood estimates during pre-approval — not at closing.
- Shop 2–3 lenders and get prequalified. Soft pulls don't affect your score. Compare LLPA-adjusted rates at the down payment level you actually plan to use, not the minimum. See our mortgage prequalification guide for what to bring to those conversations.
- Run the numbers with real numbers: the current rate, your actual insurance quote, a reassessed property tax estimate (purchase price × county millage rate), HOA, and reserve requirements. Not the seller's tax bill.
- Sign the buyer-agent agreement before touring. Required since August 2024. Know the scope, duration, and compensation terms before you see your first property.[17]
Buying a second home in 2026 is doable, and for the right buyer at the right price, it makes genuine sense. The deals that collapse aren't usually failing on the mortgage rate; they're failing on the insurance bill, a property tax reassessment nobody budgeted for, or a DTI that looked fine before the coastal premium landed.
Espenschied's stress test is worth applying before you get attached to a specific property: if your budget can't absorb a 10–20% increase in the insurance bill over the next couple of years, you're probably stretching too far. "That's not the fun, dreamy part of buying a lake house — but it's the part that keeps it from turning into an accidental investment property you're forced to rent out just to cover the bills."
And if rental income is the only thing making the math work, this probably isn't the right move. The second-home market shrank to a 2.6% share of all mortgages in 2024 for a reason.[11] Buyers who stretch at purchase tend to be the ones forced to sell into a soft secondary-home market two years later.

FAQ
Can I use an FHA, VA, or USDA loan for a second home?
Generally no. FHA, VA, and USDA loans are designed for primary residences. FHA has narrow exceptions for relocation (typically a 50+ mile move from an existing FHA-financed home) or for buying a home for a family member's principal residence. VA financing allows second-tier entitlement in rare cases but requires occupancy intent. For a true vacation home, expect to use a conventional loan, a HELOC, or a cash-out refi.[12] [19]
Can I buy a second home with an LLC to get around the higher rate?
No. Fannie Mae will not lend to an LLC for a second-home loan — that idea typically comes from investor content about commercial or DSCR loans, not conventional second-home mortgages. Putting the property in a spouse's name to qualify as separate primary residences is mortgage fraud under 18 U.S.C. §1014 if the occupancy declaration isn't accurate, and lenders can accelerate the loan via the due-on-sale clause when they catch it.[7]
What's the actual rate difference between a second home and an investment property?
In 2026, second-home rates run about 0.25–0.50% above primary; investment-property rates run about 0.50–0.75% above primary. The gap between a second home and an investment property is roughly 0.25% — not the dramatic spread some older guidance implies. The April 2022 Fannie Mae LLPA change compressed the difference. Putting 25–30% down on a second home often closes most of the remaining gap by moving you into a better LLPA tier.[9] [3]
Can I rent out my second home occasionally?
Yes, in most cases. Fannie Mae allows occasional rental of a true second home — the property just can't be designated as a rental or timeshare, and rental income can't be used to qualify for the loan.[5] The IRS uses a separate test: if your personal use exceeds 14 days or 10% of the days rented at fair market value, the property is a "residence" for tax purposes. Rent it beyond that threshold and it's treated as investment property on your return — even if it qualified as a second home on the mortgage.[20]
Can I use my 401(k) to buy a second home?
Technically yes, but it's almost never the right move. A 401(k) loan is capped at $50,000 or 50% of your vested balance and must be repaid — often within 60–90 days if you leave your job. A 401(k) hardship withdrawal triggers income tax plus a 10% early withdrawal penalty if you're under 59½. For most buyers, tapping primary-home equity via a HELOC or cash-out refi is cheaper than the tax hit — and it doesn't compromise your retirement savings.
Is the interest on a HELOC used for a second-home purchase tax-deductible?
It depends on how you use the funds. Under IRS Publication 936, home equity interest is deductible only if the loan proceeds are used to buy, build, or substantially improve the home that secures the loan. If you're drawing on a HELOC against your primary residence to fund the purchase of a second property, the interest generally does not qualify as deductible acquisition debt — because it's not improving the home that secures it. Consult a CPA to confirm how your specific use of funds will be treated before assuming a deduction.
