You Don't Need
a Guess.
You Need a Number.

A Zestimate is a statistical estimate — a regression model trained on recorded sales, tax data, and listing histories. It has never been inside your house. It doesn't know the foundation was repaired in 2019, that the kitchen was gutted and rebuilt, or that the neighbor's property backs to a commercial loading dock.

A licensed appraisal is a professional opinion of value that a credentialed appraiser will sign and stand behind in court, before a lender's underwriter, or in front of a tax board. It is based on physical inspection, a verified comparable-sales analysis, and documented adjustments for every material difference between your property and the comps.

Zestimates carry a published median error rate of 2.4% on listed homes — and 6.9% on off-market homes. On a $900,000 property, that error range exceeds $60,000. No attorney, no lender, and no tax board will accept an algorithm's output as a defensible number.

A low appraisal is not a verdict. It is a data point — one that opens three specific doors rather than closing the transaction.

Renegotiate the price. The appraisal gives the buyer documented leverage to return to the seller with a number the market actually supports. Most sellers, when shown a signed appraisal rather than a buyer's opinion, will move.

Challenge the appraisal. If a comparable sale was overlooked, if a condition adjustment was excessive, or if a recent sale within the same subdivision was excluded, a formal reconsideration of value (ROV) can be filed. Appraisers are required to respond to documented factual challenges.

Bridge the gap with a second appraisal. When the stakes are high — a contested estate, a divorce settlement, a jumbo loan — a second independent appraisal creates a defensible range that both parties can negotiate within. This practice is frequently retained specifically for that purpose.

Probate and estate settlement. Most states require a certified appraisal — not a broker's price opinion — to establish the fair market value of real property at the date of death. The IRS Form 706 estate tax return specifically requires a qualified appraisal for real property. Executors who rely on Zillow estimates expose the estate to audit risk.

Divorce and asset division. When a property is a marital asset, both parties' attorneys need a number that will survive scrutiny in mediation or before a family court judge. A licensed appraisal — signed, certified, and defensible — is the only number that removes the argument from the room. Retroactive appraisals to a specific historical date are also available when the date of separation differs from the appraisal date.

Property tax contests. The burden of proof in a tax appeal is on the property owner. A certified appraisal is the single most effective piece of evidence in a tax tribunal. Assessment offices respond to signed appraisals in a way they simply do not respond to printed Zillow pages. Many clients recover the cost of the appraisal in the first year of reduced taxes.

For a standard residential assignment, the process runs three to five business days from the inspection date to the delivery of the signed report. Complex properties — historic homes, multi-family, properties with significant acreage, or assignments requiring a retrospective date — may require additional time, which will be confirmed at engagement.

The inspection itself takes 45 minutes to two hours depending on property size and complexity. Access to all rooms, the basement, the attic hatch, and the exterior perimeter is required. Measurements are taken. Condition is documented. Photographs are taken of every room and all material features.

After the inspection, comparable sales within the subject's market area are identified, verified against public records and MLS data, and adjusted for differences in gross living area, lot size, condition, location, and amenities. The final report is delivered as a URAR (Uniform Residential Appraisal Report) — the same form accepted by every major lender and recognized by every court in the country.
