Real Estate Comps: How to Pull Them Like an Appraiser

What Counts as a Real Comp (Most "Comps" Aren't)

A comp is not just any nearby house that sold. Appraisers run every sale through five filters, and it has to clear all five before it counts.

Recency: sold in the last 90 days, ideally. Stretch to 6 months only in slow markets.

Distance: within 1 mile in urban and suburban areas. Up to 5 miles in rural markets where sales are thin.

Property match: same type, single-family to single-family, condo to condo, and within one bedroom and one bathroom of your home.

Size: finished living area within 10 to 20% of yours, and lot size within 20% for single-family homes where lot premiums exist.

Quantity: 3 to 6 qualifying sales. That's enough to triangulate a real range instead of anchoring on one outlier.

A neighbor's sale from 14 months ago tells you almost nothing about what your home is worth today. Neither does a 4,000-square-foot house stacked against your 2,100-square-foot one.

The 7.49% Mistake: Trusting an Off-Market Estimate

Most sellers make the same mistake before they ever talk to anyone: they check their Zestimate and treat it like their price. Zillow's own published accuracy data says don't.

For homes already listed on the market, the Zestimate's median error is small: 2.4%. For off-market homes, it jumps to 7.49%. And your home is off-market at the exact moment you're deciding whether to sell.

On a $400,000 Florida house, 7.49% is roughly $30,000 of uncertainty, in either direction. Redfin's estimate runs a tighter 2.07% median error, but again only for homes already on the market.

There's a second gap. These portals are MLS-sourced, so off-market sales and for-sale-by-owner transactions never show up in their comp sets. County recorder websites catch those sales.

The fix is simple: use Zillow, Redfin, and Realtor.com to build your first list of recently sold homes. Then cross-check against your county's public records before you believe the number.

Adjust Like an Appraiser, Then Compare Your Options

Raw comp prices are a starting point, not a final answer. Here's the standard method: divide each comp's sale price by its square footage, average the price per square foot across your 3 to 6 comps, then multiply by your home's finished area. Adjust for condition next: a renovated kitchen adds $15,000 to $50,000 depending on the market. Apply a monthly appreciation or depreciation adjustment to any comp older than a few months. Once you have a defensible range, the real question is which selling route captures the most of it.

Cash Flow Deals is a Florida real estate investor that gives you two offers to compare: 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. Both offers start with the same comp discipline: recent sales, tight radius, adjusted for condition. With Premium, your home may be listed through Silver Door Realty, a licensed Florida brokerage, with a licensed agent and scheduled showings. Access to financed retail buyers helps you compare your home's comp-supported retail value with an investor offer. If your own comp pull says your house is worth more than the investor math you've been quoted elsewhere, start at our Florida hub: sell your house in Florida.

With 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; those repair costs are settled from the sale proceeds, from our share, rather than paid by you up front or deducted from your agreed number. With Fast Cash, we buy as-is, with no repairs for you to make. On a Premium sale, Cash Flow Deals is paid as a separate line item on the closing statement.

Cash Flow Deals turns a strong comp pull into a real seller decision in three steps:

1. Share your comp pull, or let Cash Flow Deals run one, using recency (sold in the last 90 days), distance (about a mile in urban and suburban areas), and size (within 10 to 20% of your square footage) filters, so you can assess the valuation against appraisal standards, not just an automated estimate.

2. Cash Flow Deals uses your home's comp-supported value and condition to prepare your Fast Cash Offer and Premium Cash Offer. Silver Door Realty handles the licensed brokerage side of Premium. Your proposed net amount is typically confirmed within 24 hours. If you choose Premium, you give us permission to bring a buyer in our place; that buyer signs a new contract directly with you, title passes directly from you to the buyer, and their lender funds the purchase.

3. You compare both offers against your own comps and the traditional-listing math, side by side, then choose the route that fits your needs. You help pick the closing date. 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.
