Real estate estimates come from three different sources that don't always agree: automated valuation models pulling public data, a comparative market analysis, and a licensed appraiser's formal report. Automated models carry the widest error margin and appraisals the narrowest, reflecting the appraiser's in-person property assessment.

Factor	Traditional Route	Cash Flow Deals
Data source	Public records plus algorithm, or an agent's opinion	In-house review of comps and actual condition
Accuracy on unique homes	Weak, algorithms struggle with older or custom homes	A person actually looks at your property
What you get	A range, not a commitment	One firm cash number you can act on

The Three Sources Behind Every Estimate

Automated valuation models, or AVMs, run public records and recent sales through an algorithm and produce a number in seconds. A real estate agent's comparative market analysis, or CMA, pulls three to five nearby comps by hand and applies local market judgment an algorithm doesn't have. A licensed appraisal is the most rigorous of the three, built from an in-person walkthrough plus documented, defensible comps. Each one exists for a different purpose, and none of them are designed to match the others exactly.

Why the Numbers Don't Match

AVMs run on a lag. Public records can take 30 to 90 days to update after a sale closes, so the algorithm is often working with slightly old information. Agents bring their own read on buyer demand and pricing strategy into a CMA, which introduces judgment an AVM doesn't have. Appraisers see the property in person, which catches things no algorithm or drive-by CMA can: a finished basement, a cracked slab, a view. Three different inputs produce three different, sometimes wildly different, numbers.

Which Estimate to Trust and When

Use an AVM for a fast, free ballpark, nothing more. Use a CMA when you're actually pricing a home to list, since an agent's local read on current buyer behavior beats an algorithm's historical data. Trust the appraisal when money is actually changing hands and a lender needs a defensible number. None of the three is wrong, they're just answering different questions with different levels of precision.

Get One Number You Can Actually Rely On

Instead of collecting three different estimates and guessing which one is closest to reality, Cash Flow Deals gives you one number for each of two 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. For either offer, 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, we buy as-is with no repairs for you to make. If the 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 alongside the Premium Cash Offer.

Common questions

Are online real estate estimates reliable?

As a ballpark, yes. As a final number, no. National error rates typically run in the mid single digits, wider for unique or rural homes.

Why did my estimate change overnight?

Most automated models refresh on a set schedule, sometimes daily, pulling in newly recorded sales or updated public records that shift the underlying comps.

What's a CMA and how is it different from an AVM?

A CMA is hand-pulled by an agent using a handful of close comps plus local judgment. An AVM is fully automated with no human review.

How does Cash Flow Deals arrive at its number?

Through an internal review that weighs comps and actual condition, not just public record data.

What this means for your options

A value estimate is a starting point, not a guaranteed number.

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.
