Appraised Value vs. Market Value: Are They the Same Number?

No, not quite. Market value is a defined idea: the most probable price a property should bring in a competitive, open market under stated conditions. Appraised value is one licensed appraiser's opinion of that market value, for one property, as of one date, written for a stated use. When an appraisal is made to market value, the appraised value is the appraiser's answer to the market value question, so the two terms describe a target and a documented opinion of where that target sits.

What does market value mean in an appraisal?

Market value is not whatever a seller hopes for or whatever one buyer paid. For federally regulated mortgage lending, the definition appraisers work from is written into federal rules: market value, the most probable price which a property should bring in a competitive and open market under all conditions requisite to a fair sale, the buyer and seller each acting prudently and knowledgeably, and assuming the price is not affected by undue stimulus. The same rule (12 CFR 34.42) adds conditions: typically motivated parties, both well informed, cash or its equivalent, no special financing or concessions, and a reasonable time for exposure in the open market. Exposure time, the estimated length of time the property would have been on the market before a sale at market value on the effective date, is why a quick sale to a single buyer answers a different question.

Other definitions serve other purposes. California's property tax law defines full cash value, the amount of cash or its equivalent a property would bring if exposed for sale in the open market under conditions in which neither buyer nor seller could take advantage of the exigencies of the other, in Revenue and Taxation Code section 110. The Uniform Standards of Professional Appraisal Practice (USPAP) require the appraiser to identify which definition applies and to cite its source in the report. For the definition in plain words, see what is market value, the definition an appraiser uses.

What does appraised value add to market value?

Appraised value, the value conclusion an appraiser reports after developing an opinion under USPAP, always comes attached to four facts that market value on its own does not carry:

• The effective date, the date the opinion of value applies to. A value as of a past date of death and one as of today are two different assignments.
• The intended use, what the report will be used for: a loan, an estate, a divorce, a tax appeal.
• The intended users, the people entitled to rely on the report. A lender's appraisal is written for the lender.
• The scope of work, the type and extent of research and analysis, including whether the interior was inspected and how far the search for comparable sales reached.

An appraisal can also be made under a stated premise. "As is" values the house as it stands on the effective date. "Subject to completion" or "subject to repairs" values it as if the work were finished, which is a hypothetical condition, a condition assumed for the analysis that is known to be contrary to fact on the effective date. The report says so in plain words. What is appraised value, and who is it written for covers the reporting side in more depth.

When can appraised value and market value differ?

Appraised value is an opinion of market value, so in principle the two point at the same thing. In practice, four gaps open up.

1. The date. Market value moves. An appraised value is pinned to its effective date, and a reader who compares it with a different month's sales is comparing two dates, not two methods.
2. The premise. A value "subject to repairs" describes a house that does not exist yet. It is a market value opinion under a hypothetical condition, not a statement about the house as it stands.
3. The definition. A report made to the tax definition of full cash value and one made to the lending definition can read differently, because the definitions are written for different decisions.
4. The evidence. The appraisal is one appraiser's reading of the closed sales available, which is why every adjustment has to be shown rather than implied.

A sale price is a separate thing again: a fact about what one buyer paid one seller on stated terms, which may reflect a hurried buyer, seller credits or a family transfer. An appraiser treats a recent sale of the house itself as evidence, not as the answer.

What does that look like on a Claremont house?

These are the kinds of assignments that come in, described without addresses or figures.

• A pre-1940 Craftsman near the Village and the Colleges with a porch enclosed long ago, which public records may never have counted. The appraiser measures gross living area, the finished space above grade, instead of copying the record.
• A custom hillside home in Claraboya or Padua Hills, where view, grade and access matter and few similar sales exist nearby. The search widens along the foothills, and the report explains the radius.
• A postwar ranch house near Mills Avenue, where the closest similar sales may sit across the county line in Montclair. A sale from that side is used only when it is genuinely the better evidence, with the location adjustment explained.

The Claremont area page describes how these pockets behave as separate markets.

Which other numbers get mistaken for appraised value?

Four numbers often sit next to an appraisal, and none of them is one.

• An automated estimate such as a Zestimate, a Redfin Estimate or another automated valuation model is not an appraisal. It is a statistical estimate from records and nearby sales, made without seeing the house.
• An agent's comparative market analysis, or CMA, a licensed agent's opinion of a likely list or sale price, is not an appraisal. It is a pricing tool for a listing, not a certified opinion of value.
• The county assessment is not an appraisal either. Assessed value, the taxable value the county enrolls, follows California's rule in Revenue and Taxation Code section 51: the lesser of the factored base year value and the full cash value on the lien date. Why a long-held Claremont house shows a gap explains why that number can trail the market.
• A cash offer is not an appraisal. It is the price one buyer will pay on stated terms. Mr. Cali Offers, a separate cash-offer brand that shares the Mr. Cali name, explains how its offers are made at mrcalioffers.com/home-value; an offer from any buyer is a price, not an opinion of market value.

The four different numbers guide puts all of them side by side, and the full set of articles sits in the value types knowledge center.

Which number does your decision need?

A lender reads the appraised value in its own appraisal. An estate needs market value as of the date of death, a family law matter as of the date the parties or the court set, and an assessment appeal as of the January 1 lien date. The reader decides how the number is used; the appraiser develops it independently and shows the work.

If you are holding several numbers for one house and are not sure which one your situation calls for, read appraisal vs. estimate for the side-by-side comparison, then call (909) 324-6122 to talk through the scope before anything is ordered. Fees are set by the scope of the assignment and quoted before work begins, and they do not depend on the value.
