If you've ever received a cash offer on your house and thought "that seems low" or "that seems surprisingly reasonable," you weren't imagining things. Cash offers are calculated using a real formula, and once you understand the three variables behind it, the number stops feeling arbitrary.
The Formula Cash Buyers Use
Most cash buyers in Texas use some version of this calculation:
- After-repair value (ARV) — what the home would sell for on the open market after a full renovation. This is the ceiling the buyer works back from.
- Estimated repair costs — what it actually takes to bring the home to that condition. Higher repair estimates pull the offer down, dollar for dollar.
- Investor margin — the profit and risk buffer the buyer needs built in to make the deal viable. This covers carrying costs, financing, transaction fees on both ends, and the uncertainty of the renovation itself.
Subtract repairs and the margin from the ARV, and you have the offer. The formula isn't a secret. What varies is how each buyer estimates those three inputs, which is why offers on the same property can differ by tens of thousands of dollars.
Why Repair Costs Move the Number So Much
Repair estimates are the most variable piece of the calculation. A buyer who has low-cost contractor relationships or prices repairs conservatively will give you a stronger offer than one who is padding their estimate to protect against surprises. Foundation concerns, roof age, HVAC condition, and code violations all get factored in, sometimes more aggressively than the actual repair cost warrants. This is one reason getting two or three offers on the same property often reveals a meaningful spread in the numbers.
What the Investor Margin Actually Covers
The margin is not just profit. It covers the months of carrying costs between closing and resale, the financing cost if the buyer is using borrowed money, transaction costs on both the purchase and the eventual sale, and the uncertainty of what gets discovered once work starts. A buyer who closes in a week and takes the home completely as-is is absorbing real risk. The margin is the price of that convenience, and for most homeowners who don't want to make repairs, list traditionally, or wait months for a retail sale to close, that trade-off is worth it.
How to Evaluate an Offer You've Received
Start with a rough sense of ARV. Recent sales of similar homes in your zip code on Zillow or Realtor.com give you a reasonable starting point. Then estimate what repairs your home realistically needs. If the offer lines up with a reasonable investor margin, typically somewhere between 10 and 20 percent for a local buyer, it's in range. If it doesn't, a straightforward buyer will walk you through their numbers.
Comparing a cash offer to a traditional sale means looking at the full picture: repairs you'd need to make to list, time on market, agent commissions, and closing costs. For many Texas homeowners navigating inherited property, deferred maintenance, or a firm deadline, a well-calculated cash offer is the cleaner path forward.
