House Values: Why Your Address Doesn't Have Just One Number
Published by Cash Flow Deals · Last updated 2026-08-18 · Published and reviewed for compliance by Camilo Palacio, a Florida Licensed Realtor
A house value is not one number. It is a range built from public tax records and recent sales, and 5 to 15 percent of homes have at least one wrong field in those records, according to Opendoor's own valuation guide. That is why two tools can price the same address differently on the same day. Cash Flow Deals skips the range and reviews your specific house directly instead of running an average.
| Cash Flow Deals | Traditional Listing | |
|---|---|---|
| Timeline to a real number | Often same day | Days to weeks for a full comparative market analysis and pricing strategy |
| Repairs | Reviewed as-is, priced into the number up front | Usually need to be finished, or the price gets negotiated down, before closing |
| Fees | Flat fee, no listing commission | 5-6% commission split between listing and buyer's agent |
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. Here is exactly how it works, in order: 1. Cash Flow Deals reviews your address and your house's condition, usually within one business day of you reaching out. 2. Net price: locked in writing before any repair estimate gets scoped, arranged through a licensed local broker partner. 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. 3. Closing date: set by you, not by anyone else.
That is the whole trade. You get one real number tied to your actual house, not a range pulled from a formula. Cash Flow Deals is a real estate investor, not a brokerage, and works with sellers through a flat-fee, novation-based process.
Common questions
What is a house value, exactly?
It is an estimate built from public tax records and recent nearby sales, not a walkthrough of your specific house. Treat it as a range, not a fact, since 5 to 15 percent of homes have at least one wrong field in the records behind it.
Why do two sites show different house values for the same address?
Each tool pulls a different mix of public records and comparable sales and updates on its own schedule. A spread under 5 percent is normal; 10 percent or more usually means one tool is missing something real about your house.
Are house value tools regulated?
Yes, as of October 1, 2025. Six federal agencies, including the CFPB, adopted quality control standards requiring lenders that use these tools for credit decisions to test them for accuracy and bias.
How is [Cash Flow Deals](/) different from a house value tool?
A house value tool runs a formula against public records with no one looking at your house. Cash Flow Deals reviews your specific property directly and locks a net price in writing before repairs are scoped.
