How Much Is My House Worth? The Three Numbers You'll Get, and Why They Don't Match
Published by Cash Flow Deals · Last updated 2026-08-05 · Published and reviewed for compliance by Camilo Palacio, a Florida Licensed Realtor
You can get three different numbers for the same house, and none of them is wrong, they're just answering different questions. A free online estimate pulls public records and recent nearby sales through an automated model, with no one setting foot inside. A real estate agent's comparative market analysis adds a human eye for condition and local demand, but it's still an opinion, not a contract. A direct cash offer from a company like Cash Flow Deals is the only one of the three that's an actual number a seller can act on, locked before repairs get scoped. If you want a fast read, start with the free estimate. If you want a number you can bank on, skip straight to an offer.
| Cash Flow Deals | Traditional Listing | |
|---|---|---|
| What you get | A locked net price before repairs are scoped | An agent's suggested list price, subject to buyer offers and negotiation |
| Timeline to a real number | Often same day | Days to weeks for a full comparative market analysis and pricing strategy |
| Fees | Flat fee, no listing commission | 5-6% commission split between listing and buyer's agent |
| Certainty | Number doesn't move once locked | List price is a starting point; final sale price depends on buyer financing and negotiation |
The Three Numbers You'll Actually Get
Ask "how much is my house worth" and you'll get at least three different answers depending on who or what you ask. An online estimate, sometimes called an automated valuation model, runs your address through public records and recent comparable sales without anyone inspecting the property. A real estate agent's comparative market analysis, or CMA, uses the same comparable-sales idea but adds a human who's actually seen your house, or at least photos of it, and knows what's moving in your specific neighborhood right now. A formal appraisal, done by a state-licensed appraiser, is the most rigorous of the three and the one lenders require before funding a mortgage.
None of these numbers is "the" value of your house. Market value is really just the price a willing buyer and willing seller agree to in an arm's-length sale. Everything before that sale, the online estimate, the CMA, the appraisal, is a prediction of what that number might be, built with different data and different amounts of human judgment.
How an Online Home Value Estimate Actually Works
An automated valuation model works from data, not a walkthrough. It pulls your county's tax assessor records, recorded deed sales, square footage, lot size, and bedroom and bathroom counts, then compares your house against recently sold homes nearby with similar characteristics. Zillow publishes its own accuracy figures for its Zestimate tool and is explicit that it's a starting point, not an appraisal, with a wider margin of error for homes that aren't currently listed for sale than for ones that are.
That gap matters. A model that's never seen your renovated kitchen or your cracked foundation is working with averages, not your specific house. Federal financial regulators have gone as far as writing quality-control standards for these automated models, precisely because lenders started leaning on them for certain loan decisions and needed guardrails around how reliable they actually are.
When a Number From a Website Isn't Enough
An online estimate is fine for a quick gut check. It's not enough when money or a legal outcome depends on the number. Refinancing, settling an estate, dividing assets in a divorce, or contesting a property tax assessment all typically require either a licensed appraiser's report or, at minimum, a detailed CMA from an agent who can defend the number with specific comparable sales.
The tradeoff is time and cost. An appraisal usually runs a few hundred dollars and takes days to schedule and complete. A CMA from an agent is usually free but comes with the expectation you'll list with that agent. Both are slower than typing an address into a website, and both are more defensible if anyone ever questions the number.
A Fourth Option: Skip the Estimate and Get a Locked Number
There's a path that skips the estimate-versus-appraisal question entirely. Cash Flow Deals reviews your house directly and locks a net price before any repairs get scoped, using a novation-based, flat-fee process arranged through a licensed local broker partner rather than a standard listing.
That number isn't a prediction pulled from a model or a suggested list price waiting on offers. It's what a seller who wants an answer now, not a range to negotiate from later, actually gets. No commission math to run, no waiting on a buyer's financing to clear.
Common questions
Is an online home value estimate accurate?
It's a reasonable starting point, not a precise number. These tools work from public records and recent comparable sales without anyone inspecting your house, so they can't account for condition, recent renovations, or anything that isn't in a county record. Treat the number as a range, not a fact.
What's the difference between market value and an online estimate?
Market value is what a real buyer actually agrees to pay in a real sale. An online estimate is a model's prediction of what that number might be, built from public data instead of a live transaction. The two can match closely or diverge by a lot, depending on how typical your house is compared to its neighbors.
Do I need an appraisal to know what my house is worth?
Not for a rough idea, but yes for anything official. Refinancing, estate settlement, divorce proceedings, and tax appeals generally require a licensed appraiser's report or a detailed agent CMA, because both can be defended line by line in a way a website estimate can't.
How is a cash offer different from a home value estimate?
An estimate is a guess a computer makes about your house without seeing it. A cash offer from a company like Cash Flow Deals is an actual number tied to a real transaction, reviewed against your specific property and locked before repairs are scoped.
Why do different websites give me different numbers for my house?
Each site builds its model from a different mix of public records, recent sales, and proprietary data, and updates on its own schedule. Two tools can pull different comparable sales for the same address and land on different numbers even on the same day.

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.

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.
