Cash buyers buy below market value with their own funds, then renovate and resell or hold as rentals. Here is the real math, and why most of the gap is cost rather than profit.
Cash home buyers make money by buying properties below market value with their own funds, then either renovating and reselling them for a profit or holding them as rentals. The offer sits below full retail because the buyer absorbs the repairs, holding costs and risk that a traditional sale would otherwise leave with you.
It is a fair question, and a slightly suspicious one. If a company offers to buy your house below what it might fetch on the open market, how exactly are they profiting, and are you the one losing out? The short answer is that cash buyers are investors, and the model is not complicated or secret. The longer answer, which almost nobody spells out, is where the money actually comes from, how much of it there really is, and why the gap between a cash offer and full retail is smaller than it first looks.
Here is the whole thing, with the real math.
The simple version
Every cash-buying business runs on the same basic chain: buy a property below market value, add value to it, then either sell it or rent it out for more than it cost all-in. The profit is what is left after every expense.
That "add value" step is the part sellers pay less attention to than they should. A cash buyer is not paying full price because they are taking on everything full price would require someone to take on: the repairs, the months of carrying the property, the cost of selling it again, and the risk that any of it goes wrong. The offer reflects all of that.
The three ways cash buyers actually make money
"Cash buyer" covers a few different businesses, and they profit in different ways. We cover how to tell them apart in our guide on whether cash buyers are legitimate.
1. Fix-and-flip
The classic model. The buyer purchases a dated or distressed property, renovates it, and resells it at its after-repair value to a retail buyer. Their profit is the resale price minus the purchase price, the renovation, the holding costs and the cost of selling. This is the model most "we buy houses" companies use, and the one the worked example below follows.
2. Buy-and-hold, and the BRRRR version
Here the buyer renovates the property and keeps it as a rental, making money from monthly cash flow and long-term appreciation rather than an immediate resale. A common variation is BRRRR, buy, rehab, rent, refinance, repeat, where the investor refinances the improved property, pulls most of their original cash back out, and rolls it into the next one. In Western Massachusetts this is what tends to happen to the two- and three-family houses in Springfield and Holyoke: they are bought, brought up to standard, and held as rentals.
3. Wholesaling, a fee rather than a purchase
A wholesaler does not usually buy or renovate anything. They put a property under contract at a low price and then assign that contract to an actual investor for a fee, often $5,000 to $10,000, pocketing the difference. Their profit is that spread. It is worth knowing this model exists, because a wholesaler's offer has to be low enough to leave room for both their fee and the end investor's margin.
There is a fourth you may meet: iBuyers, the large national companies that make algorithmic offers and charge a service fee of around 5%. They mostly operate in newer, uniform suburban housing in big Sun Belt metros, and have almost no presence in Western Massachusetts or Connecticut's older markets, so most sellers here will not encounter one.
The honest math, a worked example
Take a tired single-family in the Springfield area that would be worth about $300,000 fully repaired. Here is roughly how a fix-and-flip buyer works out what they can pay. The numbers are illustrative, but the structure is exactly right.
| Step | Amount | What it covers |
|---|---|---|
| After-repair value (ARV) | $300,000 | What it will be worth renovated, based on nearby sales |
| Renovation and deleading | -$45,000 | Roof, systems, kitchen and bath, lead compliance |
| Holding costs, about 5 months | -$9,000 | Property taxes, insurance, utilities, financing |
| Selling costs on resale | -$18,000 | Agent commission, MA excise tax, closing costs |
| Investor profit, risk and work | -$30,000 | Their return for the capital, time and risk |
| Cash offer to you | $198,000 | What the buyer can pay and still make it work |
Now look at that gap. The offer is $198,000 against a $300,000 after-repair value, a difference of $102,000, which sounds enormous. But of that $102,000, about $72,000 is real cost: the $45,000 of repairs, $9,000 of holding, and $18,000 of selling costs. Only around $30,000 is the buyer's actual profit. The discount is not mostly profit, it is mostly the money someone has to spend to turn that house into a $300,000 house.
And here is the part that matters for you: you would have paid a good share of those costs anyway. If you listed the home, you would still owe the agent commission, still pay the Massachusetts excise tax, still carry the property while it sold, and you would have to fund the $45,000 of repairs yourself first, or accept a lower price for selling it as-is. The cash buyer is absorbing all of that, which is what the offer pays for.
So how much do cash buyers really make?
Less than most people assume, and less than they used to. Nationally, the typical flipped home in 2025 was bought at a median of about $259,000 and resold at $325,000, a gross profit of roughly $66,000, or a 25.5% gross return, according to ATTOM's year-end 2025 report. That was the lowest margin since 2008, down from 32.1% a year earlier.
But "gross" is doing a lot of work in that number. ATTOM's figure is the difference between the purchase and resale prices only. It does not subtract the renovation or the holding costs, which experienced flippers estimate run between 20% and 33% of a home's after-repair value. Once those come out, the real, net margin on a typical flip is a fraction of that headline 25.5%. On a $300,000 project, rehab and carrying costs alone can eat $50,000 to $90,000.
Two other things are worth knowing. Flipping made up only about 7.4% of all US home sales in 2025, and the number of flips fell to its lowest since 2020. This is a harder, thinner-margin business than the television version suggests. And margins in the Northeast, while relatively better than some regions, are earned on older, more complicated housing: the kind of pre-1978, mill-era stock that fills Springfield, Holyoke and Chicopee, where a renovation means lead compliance, ageing systems and surprises behind the walls.
What this means for you as a seller
Understanding the model tells you when a cash sale is a fair trade and when it is not.
It is a fair trade when your house cannot easily compete on the open market. If it needs a renovation you cannot fund, has a failed septic system, comes with tenants, or is full of a lifetime's belongings, you were never going to get full after-repair value anyway, and the cash buyer is taking on exactly the costs and risks you would rather not.
It is a worse deal when your house could sell well as it stands. If it is updated, easy to show, and homes in your town are selling quickly at or above asking, listing it will almost certainly net you more than any cash offer. A buyer worth dealing with will tell you that rather than take the deal.
The way to judge any specific offer is to see the whole picture side by side: the cash offer, what the home could realistically fetch listed and repaired, and what you would actually keep each way after the costs and the time involved. If a buyer will not show you that comparison, that itself tells you something.
Certainty of closing, no repairs, no showings, no commissions, and a closing date you choose. Whether that is worth the difference is your call, not the buyer's.
Where PropVio sits
Cash home buyers make money the way any investor does, by putting capital and work at risk for a return. The offer is below retail because it nets out the repairs, the holding costs, the cost of selling and a margin for the risk, and because the margin itself is thinner than the headlines suggest. None of that is a trick. The only thing that matters is whether the trade makes sense for your particular house.
PropVio shows you the math. With every offer we show you our cash price, what we think the home would fetch listed and repaired, and what you would walk away with either way, so you can see exactly where our number comes from and decide with the full picture in front of you. Every figure is an estimate, and we say so.
Common questions
How do cash home buyers make money?
They buy properties below market value with their own funds, then either renovate and resell them at a higher price or hold them as rentals for cash flow and appreciation. The profit is what remains after the purchase price, repairs, holding costs, selling costs and risk are accounted for.
Why do cash buyers offer less than my house is worth?
Because the offer nets out the costs of turning your house into a fully-valued one: repairs, months of holding, the cost of reselling, plus a margin for the risk and capital involved. Much of the gap between the offer and full retail is cost, not profit, and a good share of it is money you would have spent selling the traditional way.
How much profit do house flippers actually make?
Less than most people think. Nationally in 2025, the typical flip produced about $66,000 in gross profit, a 25.5% gross return and the lowest margin since 2008 (ATTOM). That figure excludes renovation and holding costs, which can run 20 to 33% of a home's value, so the real net margin is considerably smaller.
What is the difference between a flipper, a wholesaler and an iBuyer?
A fix-and-flip buyer renovates and resells; a buy-and-hold investor renovates and rents; a wholesaler puts your home under contract and sells that contract to another investor for a fee without buying it themselves; and an iBuyer makes an algorithmic offer and charges a service fee. iBuyers barely operate in Western Massachusetts or Connecticut.
Is selling to a cash buyer a rip-off?
Not inherently. It is a trade: a below-retail price in exchange for speed, certainty and not having to fund repairs or wait out a sale. It is a fair deal when your home cannot easily sell as-is, and a poor one when it could, which is why an honest buyer shows you the comparison before you decide.
Do cash buyers make money from me or from the property?
From the property, after they buy it, by reselling or renting it for more than their total costs. A legitimate buyer never charges the seller upfront fees; if anyone asks for money before closing, treat it as a warning sign.
