House Values: Why Your Address Doesn't Have Just One Number

What Actually Builds a House Value Number

A house value number comes from a formula, not a walkthrough. The tool behind it pulls your county's tax assessor records, recorded deed sales, square footage, lot size, and bedroom and bathroom counts, then compares your address against similar homes that sold nearby. No one from the company has seen your roof, your kitchen, or the crack in your foundation.

That formula is only as good as the records feeding it. Opendoor's own valuation guide states that 5 to 15 percent of homes have at least one wrong field in their public records, and a spread of 10 percent or more between two estimates is a real signal that a factor is missing, not random noise.

The Rule Six Federal Agencies Just Set for These Tools

The formula behind house values is not unregulated anymore. Six federal agencies, including the Consumer Financial Protection Bureau, the Federal Reserve, and the FDIC, jointly adopted quality control standards for automated valuation models used in mortgage lending, effective October 1, 2025. Lenders that use these tools for credit decisions now have to test them for accuracy, guard against data manipulation, and check for bias.

That rule exists because lenders started leaning on automated house values for real lending decisions, not just curiosity checks. If regulators wrote a rule around it, you should treat the number the same way: a starting point, not a final answer.

When a Wide Spread Means Something Is Wrong

If two house value estimates for your address land within 5 percent of each other, that is a reasonable range to work from. A spread of 10 percent or more usually means one of the tools is missing something real about your house: a renovation, a condition issue, or a bad comparable sale.

The fix is not to average the two numbers and move on. Pull 3 to 6 recent comparable sales yourself, or get a review from someone who actually looks at your specific house instead of running it through a formula.

One Number Tied to Your House, Not a Range

You do not have to reconcile two conflicting numbers yourself. In step 1, Cash Flow Deals reviews your address and your house's condition, usually within one business day of you reaching out. You compare the Fast Cash Offer, where we buy your house as-is and close, with the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. You choose.

In step 2, you review your number in writing. The number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens. We cover repair costs, and we figure out a way, so nothing comes out of your pocket. With Premium, only what your buyer's lender requires gets fixed, with repair costs settled from the sale proceeds, from our share. With Fast Cash, we buy as-is, with no repairs for you to make.

In step 3, you help pick your closing date. If your Premium buyer's loan falls through, that is our problem, not yours, and you can still take the Fast Cash Offer at its own number. You can compare the Fast Cash Offer and Premium Cash Offer based on your actual house, with clear numbers instead of a range pulled from a formula.
