Market value, appraised value, assessed value and a cash offer are four different numbers, made by different people for different jobs. Market value is a defined idea: the most probable price a property should bring in a competitive and open market under the conditions of a fair sale. Appraised value is a licensed appraiser's opinion of that market value as of a stated date, written for a stated use. Assessed value is the county's taxable value under California law, and a cash offer is one buyer's price on that buyer's terms; neither of those two is an appraisal.
Owners in Claremont often hold several of these at once: a tax bill, an online estimate, an agent's printout and an offer letter. This guide puts them side by side so you can tell which one your decision needs.
What is market value?
Market value is the price a property would most probably bring after a fair showing to the buying public, between a buyer and a seller who are informed and under no pressure. It is a concept, not a figure anyone owns. Federal banking regulators write it out at 12 CFR 34.42(h): the most probable price in a competitive and open market, with buyer and seller each acting prudently and knowledgeably, and the price not affected by undue stimulus.
That definition rests on conditions: both parties typically motivated and well informed, a reasonable exposure time, the period the property would have been on the open market before selling at that price, payment in cash or its equivalent, and no special financing or concessions bending the price. Those conditions matter here because each of the other numbers departs from at least one of them. The phrase-by-phrase walk-through is in what market value means in the definition an appraiser uses.
What is appraised value?
Appraised value is the opinion of market value a state-licensed or certified appraiser reaches after inspecting the property, researching comparable sales and writing out the reasoning, as of the effective date, the date the opinion of value applies to. The report is developed under the Uniform Standards of Professional Appraisal Practice (USPAP), carries a signed certification, and states its intended use, what the report will be used for, and its intended users, the people entitled to rely on it.
Appraised value is not a second kind of value. It is the appraiser's reading of market value for one property on one date, with the comparables and adjustments written out so a reader can follow them. See what appraised value is and who it is written for, and whether appraised value and market value are the same number.
What is assessed value?
Assessed value is the value the county assessor places on the property tax roll. A county assessment is not an appraisal: it is set under the California Revenue and Taxation Code, as of the January 1 lien date in section 2192, for every parcel in the county. Section 51 makes the taxable value the lesser of two figures. The first is the base year value, the full cash value fixed when the property was purchased, newly built or changed ownership (or as of the 1975 lien date for property held since then), compounded each year by an inflation factor. The second is the full cash value, the county's term for fair market value, as of the lien date.
That rule is why a house held for decades near the Village or north of Foothill Boulevard can carry an assessed value with little connection to recent sales nearby. The assessment was never designed to follow the market each year. The long-held-house gap is explained in assessed value vs. appraised value in California, and the base year rule in why assessed value in Los Angeles County is not market value.
Two assessors at the Mills Avenue line
Claremont sits at the eastern edge of Los Angeles County. Cross Mills Avenue or Claremont Boulevard and you are in Montclair or Upland, in San Bernardino County. Claremont is assessed by the Los Angeles County Office of the Assessor; Upland and Montclair by the San Bernardino County Assessor-Recorder-County Clerk. Both apply the same state law, but each keeps its own roll, runs its own review process and sends formal appeals to its own board, while buyers weigh the two sides differently for schools and city services. Assessed value on both sides of the county line and what the county line does to comparable sales go further.
What is a cash offer?
A cash offer is the price a buyer who intends to purchase will pay, on that buyer's terms: often as is, on a short timeline, without a financing contingency. A cash offer is not an appraisal, and it is not a valuation. It measures one buyer's willingness, and what makes it useful to some sellers, speed and certainty, is what the market value definition sets aside: reasonable exposure time, and terms no single party sets. Whether an offer suits your situation is your decision; nothing here calls any offer fair or unfair.
Mr. Cali Appraisals does not make offers. Mr. Cali Offers, a cash-offer brand that shares the Mr. Cali name, makes cash offers at mrcalioffers.com, and an offer from it is a buyer's price, not an appraisal. If you hold an offer from any buyer and want an independent opinion of market value beside it, that is a separate appraisal assignment, and the appraiser's fee does not depend on the value.
The two numbers that usually arrive with these four
An automated estimate, such as a Zestimate or a Redfin Estimate, is a statistical estimate produced by an algorithm from public records and nearby sales; it is not an appraisal, and Redfin's own page says its estimate is not a formal appraisal. A comparative market analysis (CMA), a licensed real estate agent's opinion of likely list or sale price, is built to price a listing; it is not an appraisal either. Neither carries a signed certification or a report written for a lender or a court. Theappraisal vs. estimate page sets the estimate, the CMA and the appraisal side by side.

Which number does your decision need?
- Pricing a sale. The list price is your decision with your agent. A pre-listing appraisal adds an independent opinion of market value before you choose.
- An estate or trust. Heirs, trustees and CPAs usually need market value as of the date of death, which calls for a retrospective appraisal, an appraisal whose effective date is in the past. Neither the tax roll nor an online estimate answers that question; see date-of-death appraisals explained plainly.
- A property tax review or appeal. The question is full cash value on the lien date. An appraisal made as of January 1 is evidence; the assessor or the appeals board decides. See property tax appeals on the county line.
- A divorce. Both sides and the court read one report, and the appraiser is independent of each party, including the one who pays.
- A purchase or refinance loan. The lender orders the appraisal and is its client, and the lender decides how it is used.
- Weighing a cash offer. The offer tells you what one buyer will pay; an appraisal is a separate, independent opinion of market value.
Your CPA or attorney decides how a value is used in a filing. Nothing here is legal or tax advice.
Why the numbers rarely match, and why that is not an error
They answer different questions, as of different dates, under different rules. The assessment may rest on a purchase made long ago. The offer prices speed and certainty. The estimate never saw the enclosed porch or the permitted ADU. The appraisal is tied to one effective date and to the closed sales a buyer of this house would have weighed. When two numbers disagree, ask which one was built for the decision in front of you.
Claremont widens the gaps because one ZIP code, 91711, holds several markets: pre-1940 Craftsman and Spanish Colonial Revival houses near the Village and the Colleges, postwar ranch tracts north of Foothill Boulevard, and hillside and custom homes in Claraboya and Padua Hills. A model built on averages handles those pockets unevenly. The Claremont area page describes each pocket.
Next step
If your decision needs an independent opinion of market value, request an appraisal or call (909) 324-6122. The intended use, the intended users and the effective date are agreed before work begins. The fee is set by the scope of the assignment and quoted before work begins, and it does not depend on the value. Every article on these four numbers is collected in the value types knowledge center.

Frequently asked questions
Is appraised value the same as market value?
Appraised value is a licensed appraiser's opinion of market value for one property as of one effective date, the date the opinion applies to. Market value is the definition the opinion aims at: the most probable price in a competitive and open market under the conditions of a fair sale. They are meant to describe the same thing, but one is a concept and the other is a signed opinion that a reviewer can test.
Why is my assessed value so different from what houses near me sell for?
In California, Revenue and Taxation Code section 51 makes taxable value the lesser of the base year value, compounded by an annual inflation factor, and the full cash value on the January 1 lien date. The base year is usually set when the house was bought, built or changed ownership, so a house held for a long time can carry an assessed value with little connection to recent sales. A county assessment is not an appraisal.
Is a cash offer the same as market value?
No. A cash offer is the price one buyer will pay on that buyer's terms, often as is and on a short timeline. Market value assumes a reasonable exposure time on the open market and typically motivated, informed parties on both sides. A cash offer is not an appraisal, and whether an offer suits you is your own decision.
Which value does an estate, divorce or tax appeal need?
Usually an independent opinion of market value, as of the date the matter calls for: the date of death for an estate, the agreed or ordered date for a divorce, and the January 1 lien date for a California property tax review or appeal. Your CPA or attorney decides how a value is used, and the county, board or court decides what weight it gets. Nothing here is legal or tax advice.
Does Mr. Cali Appraisals make cash offers?
No. Mr. Cali Appraisals prepares independent appraisals only. Mr. Cali Offers is a cash-offer brand that shares the Mr. Cali name, and an offer from it, like an offer from any buyer, is a buyer's price and not an appraisal.
