What Is Real Estate Valuation and How Does It Work?
Published by Cash Flow Deals · Last updated 2026-08-04 · Published and reviewed for compliance by Camilo Palacio, a Florida Licensed Realtor
Real estate valuation is the process of putting a dollar figure on a property using one of three tools: a licensed appraisal, a real estate agent's comparative market analysis, or an automated valuation model that runs recent sales data through an algorithm. Each produces a different number because each uses different inputs. Lenders require an appraisal. Sellers pricing a listing usually start with a CMA.
| Factor | Traditional Route | Cash Flow Deals |
|---|---|---|
| How your price is set | A CMA from a listing agent or a lender-ordered appraisal, both based on recent comparable sales | A locked net-price offer set upfront by Cash Flow Deals' network, before repairs are scoped |
| Who pays for it | A CMA is free; an appraisal ($300 to $500+) is usually paid by the buyer | No appraisal or CMA fee charged to the seller |
| When the number can change | A low appraisal can reopen price negotiations mid-contract | Net price is set before repair costs are factored in |
The three ways a property gets valued
Three different tools produce a property's value, and they don't always agree. A comparative market analysis, or CMA, compares the subject property to recently sold, active, and expired listings nearby. A licensed appraisal is a formal, in-person evaluation by a state-licensed appraiser, usually required by a lender before funding a mortgage. An automated valuation model, or AVM, runs public sales data and property records through a statistical model to produce an instant number, no human involved. Each tool answers a slightly different question, which is why the same house can get three different price tags depending on which one you ask.
Comparative market analysis: the free number from an agent
A CMA is what most real estate agents run before recommending a list price. It pulls recently sold comparable homes, current active competition, and homes that expired or got pulled off the market, then adjusts for differences in square footage, condition, lot size, and location. It's not an official appraisal and it's not used for lending decisions, but a well-built CMA from an agent who knows the immediate area is usually the most reliable free number a seller can get.
Licensed appraisal: the number a lender trusts
When a buyer finances a purchase with a mortgage, the lender requires a licensed appraiser to physically inspect the property and confirm its value before releasing funds. The appraiser inspects the home, documents its condition, pulls comparable sales, and produces a formal report the lender can rely on. A standard single-family appraisal typically runs $300 to $500, though the number moves with property type, location, and loan type. This is the one valuation method with real financial weight behind it, since a low appraisal can stop a mortgage from closing at the agreed price.
Automated valuation models: fast, but rough
An AVM generates a value in seconds using public records, tax data, and recent sales, run through a pricing algorithm. Online home value estimators are AVMs. They're useful for a quick ballpark, especially on a standard tract home in a neighborhood with plenty of recent sales data. They get much less reliable on unique properties, rural land, or homes with recent renovations the public record hasn't caught up on yet. No lender will fund a mortgage off an AVM alone.
Why the same house gets three different numbers
A CMA reflects what a local agent believes buyers will pay right now. An appraisal reflects what a licensed professional can defend on paper, using verified comparable sales. An AVM reflects what an algorithm calculates from whatever data it has access to, which is sometimes stale or incomplete. None of the three is wrong, they're just answering different questions with different levels of certainty. Sellers who want one number they can actually count on before repairs even get scoped sometimes work with Cash Flow Deals instead, which locks a net price upfront rather than leaving the seller to reconcile three different estimates.
Common questions
What's the difference between a CMA and an appraisal?
A CMA is an informal estimate an agent builds from comparable listings, free of charge. An appraisal is a formal, licensed evaluation a lender requires before funding a mortgage, and it usually costs $300 to $500.
Are online home value estimators accurate?
They're a reasonable starting point on a standard home in a data-rich neighborhood, but they can be off by a meaningful margin on unique properties or homes with recent, unrecorded upgrades. Treat the number as a ballpark, not a final answer.
Does my county's tax assessment equal my home's market value?
No. Tax assessed value is set by the local assessor's office for taxation purposes and often lags behind actual market conditions by a year or more. It's a different number for a different purpose than a CMA, appraisal, or AVM.
Who orders the appraisal in a typical home sale?
The buyer's lender orders it, once there's an accepted contract, and the buyer typically pays for it as part of their closing costs.

What this means for your options
A value estimate is a starting point, not a guaranteed number. Our process tests your home against the real market -- real buyers, real comps -- before you commit to a price.
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.
