The Knock Bridge Loan™ (formerly called Knock Home Swap) is designed to make it easier to buy and sell a home at the same time. It works by advancing homeowners a portion of their home equity to purchase a new house before they list.
The newer Bridge Loan Plus — launched November 2025 — also pays off your existing mortgage upfront so you're not juggling two payments while you wait for your old home to sell. Both loan options are interest-free for six months, which gives you time to sell your current home and pay back the loan amount from the proceeds.
According to Knock, 92% of customers sell their home in less than 90 days — and most sellers earn asking price or above.[1] But as a safety net, Knock provides a guaranteed backup offer worth about 85% of fair market value.[2]
Knock's Bridge Loans cost 2.25% of your home's listing price, plus $1,850 in additional loan costs.[1]
A definite benefit of working with Knock over competitors like Orchard or Homeward is that you're free to choose your own listing agent. You can offset some of the program costs by negotiating your realtor fees or working with a brokerage that offers better commission rates out of the gate.
Who does Knock work best for?
Knock’s bridge loan is designed for homeowners who are in the position of buying and selling a house at the same time. It can be especially attractive if you:
- Need to move quickly, but don't want to give away your equity to a cash buyer just for a faster close
- Want to move out of your old house before showings start
- Don’t want to risk missing out on your dream home while waiting for your current house to sell
- Need the money tied up in your current home to buy a new one
"Sellers in this position have traditionally had to list first and either hope the next home they purchase will fit perfectly with their closing date — or craft a home sale contingency into their offer, which makes it less appealing to the seller," explains Jacob Naig, a real estate agent and owner of We Buy Houses In Des Moines.
Jessica Wade, a realtor with eXp Realty in Gainesville, GA, says contingencies create a problem on both sides of the transaction:
"Typically if a buyer needs equity out of their current home or they need to lower their debt-to-income ratios, we can only make offers contingent on the sale of their current house. There is a risk to sellers for accepting conditional offers like this — making it hard to first find a home the buyers like, in addition to finding a seller willing to take a contingency. It is also stressful for the buyer because now they have to have their home show-ready at all times while living in the home."
The other choice is to sell first, says Naig, "but that means scrambling to find temporary housing." Knock is for homeowners who want to eliminate the choice altogether.
"Knock enables home owners to unlock their equity, buy a new home upfront as a non-contingent buyer, and sell their old home after they have moved out — eliminating the madness of showings, delays, and overlap logistics," explains Naig.
How Knock works
The Knock Bridge Loan works by providing a short-term 'bridge' loan and a backup cash offer so you can submit a competitive offer on a new home without it being contingent on your old house selling. You can use the loan to purchase a detached single-family home, condo, or townhome, as long as it will be your primary residence. In addition to your down payment and closing costs, the loan can cover other real estate expenses, such as moving and paying down your existing mortgage.
Here’s how it works:
- Submit an application for preapproval. There’s no cost to apply, and you should receive an estimated loan amount within 48 hours.
- Knock calculates the bridge loan amount based on your home’s value, your current mortgage balance, and how much you need to buy your new home.
- The loan amount will vary but cannot exceed $1 million. [3]
- You choose your own agent and list the property on the multiple listing service (MLS). Shop for and purchase your new home.
- If your old house doesn’t sell within six months, you can accept Knock’s backup offer, which they provide upfront (typically about 85% of the fair market value).
Knock charges a set program fee of 2.25% of the estimated list price, plus about $1,850 in additional loan costs. So if you list your home for $500,000, you'd owe about $13,100 to Knock when you settle up.
The bridge loan is structured as a single-payment loan that's repaid in full when your old home sells. Knock advertises it as interest-free during the standard 6-month term — the 2.25% program fee plus the ~$1,850 in additional loan costs cover the financing through that window. If your home doesn't sell within six months, additional fees and interest may apply.
Knock Bridge Loan Plus
In November 2025, Knock launched a second product — the Knock Bridge Loan Plus — alongside the original Bridge Loan. Both carry the same 2.25% program fee and the same guaranteed backup offer, but they handle your existing mortgage differently:
- Knock Bridge Loan (original): Your existing mortgage stays in place while your home is listed. The Knock loan can cover ongoing payments, but the mortgage itself still appears on your balance sheet — which can affect how much you qualify for on the new home loan.
- Knock Bridge Loan Plus: Knock pays off your existing mortgage upfront when the bridge loan closes. That eliminates double mortgage payments while you wait for your old home to sell, and removes the existing mortgage from your debt-to-income calculation — so you can qualify for more on the next home.[4]
That eliminates double mortgage payments while you wait for your old home to sell, and removes your existing mortgage from your debt-to-income calculation — so you can qualify for more on the next home.
Plus also supports a broader range of loan programs (including VA loans) and lets you work with any preferred lender, including banks. Knock cites a real example: a client with a $151,000 mortgage balance avoided $8,257 in mortgage payments over six months — more than offsetting the $8,100 program fee on their bridge loan.
Pros and cons to consider with Knock
âś… You can make a competitive offer and worry about selling later
With Knock, you don't have to coordinate the logistics of selling first and finding temporary housing while you house hunt or risk getting an offer rejected because it's contingent on selling your old house. Knock's bridge loan, coupled with its backup offer, makes your offer as good as cash, so you can win the home you want and remove your old house from the equation.
While swapping homes is still a tough mountain to climb, Naig has helped clients achieve the best-case scenario with Knock: "I had a client use Knock last year to buy a house in Waukee while selling their home in Beaverdale. Within 48 hours, their new offer was accepted — no contingency, no wait. When they left, we staged the old house, it went on the market clean and empty, and we were under contract in less than a week."
âś… You can use the loan for more than just a down payment
Knock's Bridge Loan can be used for a variety of expenses, including down payment, closing costs, moving expenses, and any carrying costs (ongoing mortgage payments, taxes, utilities, etc.) that accrue while your house is on the market. You can also use the loan to pay off debt like credit cards, car loans, or home equity lines of credit (HELOCs) to improve your debt-to-income (DTI) ratio and increase your buying power.
As an add on, you can also borrow up to $35,000 to fix up the house before it's listed. However, a larger loan amount may result in higher loan costs, and the increase in home value may not justify the expense. "My clients passed on the home prep add ons and instead utilized our in-house staging and cleaning teams," says Naig.
âś… You get to choose your own realtor and lender
One of the benefits of Knock is that you can choose your own agent and lender.
Choosing a top agent, as opposed to one that's assigned to you, can make or break your home sale. Top agents close more deals and generally have a better track record of selling quickly, at asking price or more. And if your agent works with a brokerage that offers competitive commission rates, the savings can offset a meaningful chunk of Knock's program fee — for example, 1.5% reduction in listing-side commission on a $500,000 home is $7,500, more than half of the typical Knock cost.
Similarly, being able to shop for the best interest rate can save you tens of thousands of dollars over the life of your home loan.
❌ The Knock Purchase Offer provides security, but it won't match your list price
Knock's Bridge Loan comes with the Knock Purchase Offer — a guaranteed backup offer in case your house doesn't sell within the 6-month loan term. However, it's typically only about 85% of fair market value,[2] which means a meaningful gap if your home would have fetched full asking on the open market.
Fortunately, sellers rarely have to exercise this option — the vast majority of Knock's clients get their homes sold within 90 days, according to the company.[5]
"The Knock offer is nice if for nothing else than a bit of a psychological floor for the seller (85% of market value-ish), but in our case, we beat that by well over 12% on the open market," says Naig.
❌ You'll pay a premium for the convenience
While the loan itself is interest free for 6 months, Knock's fees will add a minimum of 2.25%, plus $1,850, to your closing expenses. Ongoing home ownership costs will be covered by the loan while your house is listed, but be deducted from your final payout at closing.
"What you’re buying with that price tag is peace of mind and leverage," says Naig. "For certain clients, eliminating the risk of having a contingency clause denied is absolutely priceless."
For perspective, Knock's fees are lower than most iBuyers, which charge 5% or more. However, iBuyers allow you to cut realtor commissions out of the equation. That said, you'll almost certainly get a higher price with an open market listing, even after accounting for agent fees.

| Trustpilot | 4.7/5 | 193 |
| Zillow | 4.8/5 | 761 |
| Weighted Average: | 4.8/5 | 961 |
Knock’s reviews are mostly positive. The company has an average customer rating of 4.78 across 961 online reviews.
Most of the positive Knock Bridge Loan reviews say the service is easy and convenient. They praise the company’s high-quality customer service and communication, calling agents professional and knowledgeable.
Negative reviews point to hiccups in the process that delayed closing and led to missed selling opportunities. The company is good about responding to both positive and negative reviews.
âś… Easy way to buy and sell
Satisfied customers said Knock Bridge Loans made it easy and less stressful to buy a new home before selling their old one.
The entire process was so easy. I was able to move into my new home while getting my old home ready for sale. I don’t intend on moving again but it I do I would definitely use Knock again.
I was amazed on how easy this process was. Everyone that we had talked to was very kind and explained everything. Questions...they had all the answers. We are now sitting in a beautiful home sooner than we thought thanks to them!!!
âś… Great customer service
Many reviewers noted the excellent customer service that Knock agents and loan officers provided. They said everyone was professional, polite, helpful, and responsive, adding that they were often able to get their questions answered quickly.
We were given an explanation of the entire loan process and if we had any questions, all we had to do was pick up the phone and someone was always there to provide us with answers. It was an easy and pleasant experience
Of all the transactions I’ve made in my life, whether business and personal, Knock has been incomparable. The professionalism, compassion, the dedication and commitment to me and my husband has been over the top. The experience from beginning to end has been pleasurable...Unquestionable confidence in every one involved with Knock.
❌ Complicated process
Some unhappy clients said the amount of paperwork required, coupled with multiple points of contact, was confusing.
Every day there was a new request for documentation. Lack of process and procedure to the point where it seemed totally random. Our contact was not helpful. If it wasn't for the efforts of our realtor and the Zillow rep this may not have gotten done.
Often times it was like the person I was currently dealing with, had no knowledge of the other people I had already resolved the issue with. I felt the communication through the whole process was very poor. Also, any time I had a question, I had to make multiple attempts and leave multiple messages for my loan officer.
How to evaluate Knock against alternatives
Naig says that when looking into a bridge loan or buy-before-you-sell program, you need to consider the fine print. Look specifically for:
- Fees and commissions: Are there sneaky upcharges, inflexible commissions, or open-ended costs that you may not know until you settle up? For example, some companies will actually buy your home upfront but then withhold a certain amount for repairs and maintenance while it's listed — resulting in a lower payout, since they determine how much to charge and even what kind of repair concession to offer the buyer.
- Agent selection: Can you use your own, or do you have to choose from their network? Having the freedom to shop around for the right agent can add tremendous value through a higher sale price and faster closing. It can also help to offset some of the program costs, especially if the realtor's willing to negotiate their fee or you go through an agent matching platform like Clever that offers built-in commission savings through their network.
- Backup offer price: Is it on or under market value, and will they lock in the amount upfront? Some companies may also use third parties such as Opendoor or Offerpad to furnish the backup offer, so just be sure to check for additional fees tacked on to the sale price.
- Lender flexibility: Are they going to insist you use their financing — or charge you a higher program fee if you don't? Say you're purchasing a $500,000 house with a $400,000 mortgage. Securing even a 0.25% interest rate deduction can save you $28,000 over the life of the loan, so the freedom to choose your own lender is money in your pocket.
- Timeline: How long do you have to sell your original house before you have to pay for an extension or start accruing interest? Some companies give you six months, while others only give you four. In slower markets, a shorter selling window could add undue stress.
Knock competitors
Knock’s bridge loan is a solid option if you need cash to buy a new home before selling your old one — or if you could use some extra money to prep your house for market. But the fees can add up, and unless you can sell your house fast, you’ll have to start paying interest on the loan.
You might want to review some alternatives before you sign up with Knock to see if you can get a better deal.
Knock vs. Clever Offers
Clever Offers can also help you sell on your timeline by helping you explore cash offers and other sell-fast solutions providing cash upfront, plus the option to list for additional upside.
Clever’s network includes investors and iBuyers, buy before you sell programs, and top-rated agents familiar with various cash offer products. This means you get a range of options to choose from, so you can make a more informed decision.
The service is free for home sellers. And if you decide to go with Knock, you can take advantage of lower agent commissions (about 1.5%) offered through Clever's real estate network, saving you thousands on your home sale.
Knock vs. Homeward
Homeward has a buy-before-you-sell option that’s practically the same as Knock’s bridge loan, but it’s more expensive. Homeward charges a 3.5% program fee, while Knock's fee is 2.25%.[6]
Homeward does offer more services than Knock. You can sell directly to Homeward, getting most of your home value upfront, minus a reserve used for home prep and selling costs. Homeward will then work with your realtor to put your home on the market and give you a second payout when it sells, minus service fees (~7%), realtor commissions (~6%), and carrying costs (variable). The company also has in-house mortgage and title services to streamline transactions and potentially help you save money off the program fees.
Knock vs. Opendoor
Opendoor is known for its fair offers and hassle-free home sales. As the nation’s largest iBuyer, it delivers a cash offer within 24–48 hours and pays closer to market value than other cash buyers.
You can close in as little as two weeks, which is great if you need to move quickly. But Opendoor charges a 5% service fee — more than twice what Knock charges. Knock also lets you list your home on the MLS, giving you the opportunity to sell for at or above market value.
Knock vs. Orchard
Orchard’s Move First program is a similar buy-now-pay-later option. However, you must use Orchard’s agents to sell your home, giving you less flexibility than with Knock. Orchard can also be more expensive, with service fees ranging from 1.9–7% of your home's final sale price.
And while Knock gives you six months to sell, you only get four months with Orchard. Orchard does give you a backup offer, but it doesn’t specify the amount, and reviewers have complained about the offer being low.
Knock vs. Flyhomes
Like Knock, Flyhomes offers a bridge loan that lets you tap your home's equity to make a non-contingent offer on a new home. The big differences are in cost structure and product focus: Flyhomes' bridge loan is offered at a market-rate APR (recently around 9.99%), while Knock charges a flat 2.25% program fee with no interest during the standard six-month term. For short timelines, Flyhomes' interest-only structure can pencil out cheaper. Over a full six months, Knock's flat fee tends to be the safer math.
Flyhomes also operates a smaller direct-buyer program in select markets, while Knock focuses exclusively on the bridge loan plus the Knock Purchase Offer as a backup.
What are the requirements for Knock's Bridge Loan?
According to Knock, most homes will qualify for the bridge loan, including townhomes and certain condos. Ineligible properties include:
- Manufactured homes
- Mobile homes
- Multi-family properties
- Deed-restricted properties
- Homes with significant water or foundation damage
- Homes in poor condition
- Condos that are considered non-warrantable or located in an unserviceable area
In most markets, the maximum listing price is $1.5 million.[1] High-cost counties in California and Washington have a $2.5 million limit.
Knock's bridge loan goes through Knock Lending, so it follows standard mortgage underwriting — meaning Knock will verify your home equity, credit, income, employment, and the new home's collateral before approving the bridge loan amount.[7] Knock doesn't publish a minimum credit score or DTI threshold, so you'll need to get prequalified to verify your eligibility. Pre-qualification is free and takes about 48 hours.

FAQs
How does Knock Home Swap work?
Knock Home Swap is now called the Knock Bridge Loan, and Knock now offers two versions: the original Bridge Loan and the newer Bridge Loan Plus (launched November 2025), which pays off your existing mortgage upfront. With either product, you get an advance of your home's equity as a cash payment to buy a new house before selling your old one — then work with your own agent to list and sell. A portion of the loan can also be used for pre-listing repairs and improvements.
Is Knock an iBuyer?
No, Knock is a bridge loan provider that lets you tap into your home's equity as a cash loan to purchase a new house before your current one sells. However, if you can't sell your house within six months, you can accept Knock's guaranteed backup offer, which is typically about 85% of fair market value.
Is Knock legitimate?
Yes, Knock is a legitimate company. It was founded in 2015 and has an A+ Better Business Bureau rating. According to the company, it has relationships with more than 120,000 realtors in 75 markets[8] across the U.S. Its headquarters is in Atlanta and maintains a 4.78/5 rating across 961 reviews on Trustpilot, BBB, and Zillow.
How much will Knock advance a homeowner?
The exact loan amount will vary based on how much equity you have in your home, but can't exceed $1 million. If you use Bridge Loan Plus, your practical buying power on the next home is typically larger, because Knock pays off your existing mortgage upfront — which removes it from your debt-to-income calculation and frees up more borrowing capacity on the new home loan.
