Mark Spain Real Estate and Opendoor both advertise cash offers and quick home sales, but there are big differences in the way they operate.
- As an iBuyer, Opendoor purchases homes outright — typically for less than market value — in order to resell them on the open market. It charges a variable service fee (5%+) in exchange for a quick cash sale.
- As a real estate brokerage, Mark Spain pairs home sellers with a listing agent to present cash offers from investors and other iBuyers alongside the option of a traditional listing. Whether you accept a cash offer or put your home on the market, you pay a standard listing commission to your Mark Spain agent.
If you need to sell fast, your best bet is to shop offers from a variety of cash buyers. Requesting an offer is always free and comes with no obligation to sell, so it’s in your interest to cast a wide net.

Mark Spain vs. Opendoor: What's the difference?
Both Mark Spain and Opendoor can furnish a cash offer for your house, but they work very differently. Opendoor buys your home directly — no agent required — while Mark Spain assigns you a listing agent who sources offers from third-party investors and iBuyers on your behalf. That middleman structure is the most important difference between the two: With Mark Spain, you'll have to pay a realtor commission even on a cash sale, and your offer quality depends entirely on which buyers your agent can reach.
It also means the experience can be less straightforward than sellers expect. Many customers who contacted Mark Spain specifically for a cash offer report being steered toward a traditional listing instead — sometimes without ever seeing a cash offer. For example, a review posted to the Better Business Bureau on April 21, 2025 provided this description of Mark Spain's Guaranteed Offer program:
"I contacted **** Spain for a cash offer.. The agent started talking about a listing and showings. I brought up the guaranteed cash offer mentioned in the ad. She said we try to get you an offer. If there are no offers then we will list it as a house for sale. In order to get a cash offer I must sign a listing agreement, agreeing to sell my house thru *** real estate services. In other words they are just looking for houses like any other real estate company, only they use very deceptive ways to get a listing."
Opendoor, by contrast, gives you a direct offer within 24–48 hours, with no obligation to proceed. Opendoor is also more widely available, operating in major metro areas across the U.S., while Mark Spain's primarily operates primarily in the South.
Customer reviews indicate that Mark Spain may even present an offer from Opendoor if you're in one of their service areas. However, there's no requirement to work with an agent when selling to Opendoor. If you do accept an iBuyer's offer through Mark Spain, you'll pay a standard realtor commission on top of any service fees.
Mark Spain vs. Opendoor: How they work
Mark Spain pairs sellers with a real estate agent to present options
Mark Spain Real Estate is a real estate brokerage headed by Mark Spain, a former Keller Williams agent who founded the company in Atlanta in 2016. It has since expanded to major cities throughout the Southeast and has repeatedly been named one of the fastest growing companies in America by Inc. Magazine.[3]
Mark Spain offers a range of real estate brokerage services, including a Guaranteed Cash Offer program for home sellers (cash offers sourced from third-party investors and iBuyers) and traditional brokerage services for buyers and sellers. To get a cash offer, you must first sign a listing agreement with a Mark Spain agent.
"Unless you had a signed listing agreement, you can't make an offer for any of those companies," explains Maria Muedas, a former Mark Spain agents who now owns Green Valley Real Properties in Greensboro, NC. "So basically what you would do is go to the listing appointment, get the listing agreement signed, and then go back to the office and send the video in to all of the investor companies."[1]
Opendoor makes direct cash offers on homes
Opendoor was founded in San Francisco in 2014 and is the largest iBuyer in the country. It offers a couple of different ways to sell your home, including its core cash offer service (Sell to Opendoor) and a newer hybrid option called "Cash Now, More Later," which launched in 2025.
With Cash Now, More Later, Opendoor pays you a cash price upfront, then renovates and resells your home, passing along any additional proceeds above the initial offer price — minus fees and renovation costs. By the end of 2025, Cash Now, More Later represented approximately 35% of Opendoor's weekly home purchase volume — a share that held steady through Q1 2026.[4]
Home seller Carmela James, who received both a standard cash offer and a Cash Now, More Later offer from Opendoor for her Phoenix-area home in 2024, says the upfront amount was "maybe around $8,000 to $10,000 lower" than the regular cash offer. "They said the reason it is less upfront is because they are taking on the risk of selling the home later," she recalls. "But they didn't really show a super detailed breakdown of exactly how much was going to each piece. It was just more explained as a buffer on their side."[2]
Offers
Mark Spain doesn't make direct offers
Mark Spain doesn't set its own offers — they come from whichever investors or iBuyers your assigned agent submits your property to. A recent survey of over 700 real estate investors found that investors typically aim to offer between 60–80% of a home's after-repair value, with a median offer of 67.5%. iBuyers may come in closer to market value, but they also charge service fees and make deductions for repairs.
Andrew Velez, a Realtor with ReMax Advisors in South Florida who has worked with several iBuyer programs, told us that offers around 80–85% of value aren't unusual — and that sellers typically reject them unless they're under real pressure to sell.[5] "I think those iBuyer scenarios work for a probate case or an inherited property," he said, "but otherwise the sellers want more money."
Opendoor typically pays slightly less than market value
During the early 2020s, iBuyers like Opendoor gained a reputation for paying at or even above fair market value for homes. But since the housing market has cooled, so have their offers.
"Before 2022, iBuyers' offers were competitive," explains Christopher Trumbach of Florida Prestigious Homes. "They were coming in close to market value, or at least what the sellers were looking for. But when the market changed, they started slashing the numbers. So now, the way the market is here, I've not really had anybody motivated to go with the iBuyers."
Our team recently analyzed 410 homes purchased by Opendoor between 2023 and 2025. The data from these properties showed that, on average, Opendoor pays sellers 4–13% less for homes than it eventually resells them for. Using the resale price as a gauge of market value, a seller with a $500,000 home can expect to leave about $20,000–65,000 on the table when selling to Opendoor, before accounting for service fees and repair costs.
While these figures are averages, individual sellers may see a wider or narrower margin between Opendoor's offer price and resale price. Brandon Capelle, a realtor with ReMax Advantage Plus in Minneapolis, recently helped a buyer close on an Opendoor home, noting that Opendoor had purchased the property for $234,000 in January 2025 and relisted it at $262,000 just three months later — a margin of roughly 12%.[6]
Fees and other costs
Mark Spain fee does not include service fees charged by individual buyers or brokerage fees paid to a buyer's agent. Realtor fees remain negotiable.
Mark Spain charges a standard realtor commission (typically 3%+)
Mark Spain charges home sellers a realtor commission on all home sales — whether you put your home on the market or request a cash offer. While not publicly disclosed, reviews for Mark Spain indicate rates are typically 3.5% of the home sale price, slightly above the industry average of 2.5–3% and well above the 1–2% commission rate you can find with some brokerages. A former Mark Spain agent who still works in markets where Mark Spain is active confirmed the company's rates are a firm 3.5%, even on off-market deals where the home never hits the MLS.
In a typical cash offer scenario, you can avoid paying realtor fees altogether, since you'll be dealing directly with the buyer.
Opendoor charges a variable service fee (formerly 5%)
Opendoor charges a variable service fee for both its iBuyer and Cash Now, More Later programs. While the fee was formerly 5%, it now varies by market and home price.[7] Sellers also pay standard closing costs, which usually run about 1% of the sale price. If you need extra time in your home after closing, Opendoor offers a late checkout option for up to 17 days after closing, at a daily rate plus a security deposit.
Repair deductions are the biggest unknown with Opendoor. They're only finalized after Opendoor's inspection, and reviews suggest they can range from negligible to tens of thousands of dollars. While there's no fee to cancel at this point, it may be too late if you're depending on the cash from this sale to close on another house.
Charlotte-area realtor Melissa Young describes a pattern she's seen among sellers: "The offer in the beginning seemed reasonable, but after going through inspections, a lot of things changed. By that point it was too late — their son was already under contract on a new construction home closing in about a week. It felt like bait and switch."
Customer reviews
Average customer rating based on aggregate ratings from Google, Trustpilot, the Better Business Bureau, Yelp, and Reviews.io
Mark Spain reviews are positive, with some complaints about its Guaranteed Offer
Mark Spain reviews are generally positive. The company has a 4.6 average rating across 5,634 online reviews.
Most positive reviews are from customers who have listed with Mark Spain and have had good experiences with their agents. For example, these customer reviews are typical of many:
Mark Spain sent a great agent ... to us, and we could not have been happier. He spent a lot of time with us and answered all of our questions. He helped us pick a great price and we got more than we even expected.
However, reviewers who tried the Guaranteed Offer program specifically tend to be less satisfied, citing low offers and pressure to sign a listing agreement.[8] [9] [10]
As this reviewer said:
MS does not offer the cash themselves. They have 'Investors' who will gladly take your property and in my case, for $120,000 less than the asking price.
Another Mark Spain customer noted:
This company was a nightmare. My husband and I reached out to them due to offering a guaranteed cash offer. We needed to sell and relocate quickly for work. Never got a cash offer. We were coaxed into putting the house on the market.
Opendoor reviews are mostly positive, with some complaints about repair costs
Opendoor reviews are also good overall. The company gets especially high marks for its convenient process, which removes a lot of the hassles of selling a house the traditional way (preparing the home for sale, vacating for showings, etc.). For example, this review from Trustpilot is relatively typical for Opendoor:
For me, the cut they take off of the price of your home is well worth the hassle they remove from the process. I was able to set the date that we closed, not have to worry about preparing for showings, I didn't have to worry about how long it would be on the market before sale, and I was able to put that time and energy into planning the rest of my move.
Opendoor complaints tend to revolve around unexpected repair deductions and final offers being significantly lower than initial estimates. As one recent customer said:
They first offered a decent offer, then after they come, they lower the offer. Then add a huge amount for repairs which were not needed.
Availability
Mark Spain operates primarily in the Southeast and Texas
Mark Spain Real Estate operates in the following markets:
Jacksonville, FL, Orlando, FL, Tampa, FL, Athens, GA, Atlanta, GA, Charlotte, NC, Greensboro, NC, Raleigh, NC, Nashville, TN, Dallas, TX, Fort Worth, TX
To qualify for Mark Spain's Guaranteed Offer program, your home generally needs to be a single-family home built after 1950, valued between $50,000 and $1.5 million, and owner-occupied or vacant. Homes in or near flood zones, with significant foundation issues, or with unpermitted additions are typically ineligible, as are distressed or bank-owned properties.[11] However, meeting the minimum purchase criteria doesn't guarantee that Mark Spain will make a cash offer on your home.
Opendoor operates in major markets across the U.S.
Opendoor currently buys homes nationwide, including major metros, suburban areas, and smaller cities throughout the contiguous United States.[12]
Opendoor's nationwide expansion comes alongside a broader restructuring as it works to rebuild profitability under new leadership and a strategy it calls "Opendoor 2.0." While the company purchased just 8,241 homes in 2025 — roughly half the 14,684 it purchased in 2024 — momentum has accelerated since. In Q1 2026, Opendoor purchased 2,474 homes (up 45% from Q4 2025) and signed over 5,000 acquisition contracts, its highest volume since 2022.[4]
Regardless of location, Opendoor's offers are limited to single-family homes and townhomes (condos and duplexes in select areas) that are owner-occupied or vacant, not in foreclosure, and free of significant structural issues or unpermitted additions. Again, meeting Opendoor's eligibility criteria doesn't guarantee an offer.
