Fair Market Value of a Home: The Actual Legal Definition
Published by Cash Flow Deals · Last updated 2026-08-18 · Published and reviewed for compliance by Camilo Palacio, a Florida Licensed Realtor
Fair market value is legally defined as the price a willing buyer and willing seller would agree on, with neither required to act and both reasonably informed, per IRS guidance. Cash Flow Deals gives you two offers to compare alongside whatever formal valuation your situation requires: the Fast Cash Offer, where we buy your house as-is and close, and 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.
| Cash Flow Deals | Traditional Listing | |
|---|---|---|
| Timeline to an agreed offer number | Often same day | Days to weeks for pricing, then 30-45+ days once under contract |
| Repairs | No repairs for you to make with the Fast Cash Offer; with the Premium Cash Offer, only the buyer's lender-required repairs get fixed. We cover repair costs, and we figure out a way, so nothing comes out of your pocket; Premium repair costs are settled from the sale proceeds out of our share. | Buyer inspection often triggers repair requests or credits |
| Fees | You get the amount you agree to, and we'll handle any costs on top of that. | 5-6% agent commission plus 1-3% seller closing costs |
| Certainty | 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. | Sale price depends on buyer financing, inspection, and negotiation |
The Actual Legal Definition, Not the Website Definition
The IRS defines fair market value as "the price that property would sell for on the open market... the price that would be agreed on between a willing buyer and a willing seller, with neither being required to act, and both having reasonable knowledge of the relevant facts." That's a legal standard, not a single fixed number -- it moves with the method used and the date it's measured.
Three things typically hinge on this figure: your property-tax assessment, any capital-gains calculation on a sale, and the stepped-up basis on an inherited property.
Four Ways to Find It, Ranked by How Defensible They Are
A licensed appraisal is the most defensible and typically costs $300-$600 for estate or tax purposes, per Opendoor's own guide. A professionally prepared CMA is usually free but relies on 3-5 comparable sales and professional judgment. An online estimator is free and instant but carries a documented 2-7% error margin. DIY comparable-sales research from county records is free but takes real time to do correctly.
For anything tied to taxes or an estate, Cash Flow Deals can give you two written offers to compare alongside whichever formal valuation method your situation actually requires: the Fast Cash Offer, where we buy your house as-is and close, and 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.
Cash Flow Deals' Process: 3 Steps
1. Cash Flow Deals reviews your property details directly and gives you two written offers: the Fast Cash Offer, where we buy your house as-is and close, and 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.
2. 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 the buyer's lender requires gets fixed, with costs settled from the sale proceeds out of our share. With Fast Cash, you sell as-is without making repairs.
3. You help choose the closing date, and funds move at closing. With Premium, the buyer's lender funds the purchase directly from you. If the buyer's loan falls through, that is our problem, not yours, and you can still take the Fast Cash Offer at its own number instead of the Premium Cash Offer.
Common questions
Do I need fair market value for taxes, not just a sale?
Often, yes, property tax assessments, capital gains calculations, and inherited-property basis all commonly hinge on a defensible fair market value figure, not just a casual estimate.
How do the Fast Cash Offer and Premium Cash Offer work?
You choose between the Fast Cash Offer, where Cash Flow Deals buys your house as-is and closes, and 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. With Premium, you sign with us at an agreed number and give us permission to bring that buyer in our place. The buyer signs a new contract directly with you, title goes straight from you to the buyer, and their lender funds the purchase. We are paid as a separate line on the closing statement. 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. Only what the Premium buyer's lender requires gets fixed, with repair costs settled from the sale proceeds out of our share; Fast Cash is bought as-is. If the Premium buyer's loan falls through, that is our problem, not yours, and you can still choose the Fast Cash Offer at its own number instead of the Premium Cash Offer.
What if something's wrong with the house nobody could see before the offer?
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.

What this means for your options
Every path to selling a house has real tradeoffs.
Wait and see
Keep the property as-is and hope conditions improve. The mortgage, insurance, and upkeep keep costing money while you wait, with no set date for things to turn around.
List with a traditional agent
Standard MLS listing, typically 5-6% in commission, and a financed buyer whose deal depends on appraisal, inspection, and lender approval — any of which can fall through after weeks on market.
Sell to Cash Flow Deals
Two offers for your house, Fast Cash or Premium Cash, and you choose. Cash: Cash Flow Deals buys the house as-is and closes. Premium: More money. A pre-approved FHA or conventional buyer we already have buys directly from you.
