“We buy houses” companies offer a quick sale for cash, often with no showings and no repairs. They make their money by paying less than a home would sell for on the open market, then fixing and reselling it, renting it out, or selling their contract to another investor. A North Carolina deputy attorney general told AARP that sellers to these buyers can end up with about 60% of market value. (AARP, “We buy houses” offers)
Many of these investors price offers with the “70% rule”: pay no more than 70% of what the home should sell for after it’s fixed up, minus the cost of the repairs. Taking Petersham’s median single-family sale ($462,000, the 12 months to January 2026) as the after-repair value, that’s at most $323,400 before any repairs come off, $138,600 under the market price. (Rocket Mortgage, the 70% rule)
Instant-offer companies (iBuyers) offer closer to market value, then take a service fee and deduct the repairs their inspection finds. A National Bureau of Economic Research study found iBuyers bought homes about 3% below market value, with Opendoor’s service fee around 6.5% in 2020; in 2022 the FTC found Opendoor’s offers had come in below market value and settled with it for $62 million. (NBER w28252, iBuyers; FTC, Opendoor settlement (2022))
Listing your home puts it in front of every buyer looking in Petersham, where 10 other homes are for sale right now. Buyers compete on price and terms, and you choose the offer. You pay the commission you agree on in your listing agreement, which is negotiable, and the deed stamps and other costs below apply however you sell.
A cash sale can make sense when speed or certainty matters more than price: a home that needs major work, an estate that has to be settled, or a deadline. Before you sign one, get a market valuation to compare it with, and read the contract closely, including who the buyer really is and when they can back out.
| Cash investor | Instant offer (iBuyer) | Listing your home | |
|---|---|---|---|
| How the price is set | The investor’s resale or rental math, often the 70% rule | The company’s estimate of market value, about 3% under it in one study | Buyers competing for your home |
| What comes off | Repairs, at the investor’s estimate | A service fee and repairs | The commission you negotiate |
| On a $462K home | At most $323K before repairs | Market estimate minus the fee and repairs | What buyers pay, minus the commission |
| Showings and repairs | None | An inspection; repairs come off the price | Showings; repairs are your choice |
