Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team. Definitions come from the California State Board of Equalization (BOE), the Department of Real Estate (DRE) and the Federal Housing Finance Agency (FHFA); sources are listed at the end.

No single number is your home’s value. A house in California has several: what a buyer will pay, what an appraiser concludes, what the county Assessor enrolled for tax, and what a cash buyer offers. They answer different questions and are often far apart. This guide explains each one, where the official data comes from, and how to turn them into a decision when you sell.

Four “values” for one California house

Market value	The BOE defines full cash value as the price the property would bring in an open market sale where neither buyer nor seller can take advantage of the other, and both know the property’s permitted uses and restrictions
Appraised value	An opinion by a licensed or certified appraiser, who must follow the Uniform Standards of Professional Appraisal Practice (DRE Reference Book)
Assessed value	The Assessor’s taxable value. Under Prop 13 it is the base year value, generally raised no more than 2 percent a year, so it often sits well below market value (BOE)
Cash offer	A buyer’s price to purchase as-is, with no listing, showings or financing contingency. It is a business price, not a market value opinion

Is the assessed value on my tax bill my home’s value?

No. The BOE explains that a property is reassessed to market value only when ownership changes or new construction is completed. In between, the assessed value rises by inflation up to 2 percent a year, or the market value if that is lower.

A home owned for many years can therefore have an assessed value far below what it would sell for. The BOE adds that the Assessor may also lower the assessed value to recognize a decrease in value.

The reverse matters to sellers too. Selling is a change in ownership, so the buyer’s assessed value will be reset to the purchase price. Our Prop 13 and Prop 19 reassessment guide covers the exclusions.

How do appraisers and agents estimate market value?

The usual method for a house is the sales comparison approach: compare recent sales of similar homes nearby and adjust for differences such as size, condition, lot, age and location. An agent’s comparative market analysis follows the same logic but is not an appraisal.

The DRE’s reference book says that when a formal valuation is needed, a professional appraiser should be consulted, and that licensed and certified appraisers are bound by the Uniform Standards of Professional Appraisal Practice.

Condition drives the gap. Comparable sales of renovated homes overstate the value of a house that needs a new roof, kitchen or foundation work.
Permits matter. Unpermitted additions may not count toward living area. See our unpermitted work guide.
Timing matters. Prices move; a comparable that sold months ago may not reflect today’s market.
Appraisers are licensed. The California Bureau of Real Estate Appraisers (BREA) licenses appraisers, and you can check a license on its website.

What official data can I use to check a price?

County Assessor and Recorder: parcel details, assessed value and recorded sales for your county. Use them to confirm square footage, lot size and the prior sale date.
FHFA House Price Index: a weighted, repeat-sales index built from repeat mortgage transactions on single-family homes whose loans were purchased or securitized by Fannie Mae or Freddie Mac. FHFA publishes it for states, metro areas, counties, ZIP codes and census tracts. It shows how prices have moved in an area, not what one house is worth.
U.S. Census Bureau QuickFacts: owner-reported median home values for California cities and counties, useful for context only.
Our own California reports: see the California home price and sales report and the statewide home seller report.

Websites that show an instant estimate are automated models. They are not appraisals and are not an official source. Treat them as a rough starting point and check them against recorded sales near you.

Why a cash offer is different from market value

A cash offer prices in things a retail sale leaves to the seller: repairs, carrying costs while the buyer holds and resells the home, and the risk that costs run over. In return you avoid listing prep, showings, financing and appraisal delays, repair negotiations, and agent commissions.

For a move-in-ready home in a hot area, a listing may net more. For a house that needs work, is inherited, has tenants, or must sell fast, the faster, certain sale can come out ahead once time and costs are counted.

Our offers are written, include no fees or commissions, and carry no obligation. We make no guarantee that a cash offer will be higher or lower than a listing price for your home.

How to sell a house in California once you know the range

Collect the facts. Pull the parcel record from your county Assessor, your last deed, and a list of repairs and permits.
Look at recent nearby sales. Choose homes of similar size and condition that sold recently, and note adjustments for the differences.
Add up what a listing costs. Include commissions, repairs, seller closing costs and months of mortgage, taxes and insurance. Our seller closing costs guide lists the usual items.
Get a written cash offer. Compare the net from each path, not just the headline price. See how we buy houses across California.
Decide on your timeline. Choose the path that fits your deadline, whether that is a probate date, a foreclosure sale or a move.

We buy in every metro, including Los Angeles, San Diego, Sacramento, San Jose, Fresno and Riverside.

California home value FAQ

Is my county assessed value the same as market value?

No. Under Prop 13 the assessed value is generally the base year value plus increases of no more than 2 percent a year, so it can be much lower than market value.

Is an online estimate an appraisal?

No. An appraisal is an opinion by a licensed or certified appraiser who follows USPAP. Online estimates are automated models.

What does the FHFA House Price Index tell me?

It tracks average price changes from repeat sales or refinancings of single-family homes in an area. It does not value an individual house.

Will a cash offer match market value?

Not necessarily. A cash offer reflects an as-is purchase with repairs, holding costs and risk taken on by the buyer, in exchange for speed and certainty.

Do I need an appraisal to sell for cash?

No. A cash sale does not depend on a lender appraisal, though you may order one if you want an independent opinion.
