Market value is the foundational concept behind every appraisal, CMA, and listing price discussion in real estate. It is defined as the most probable price a property would sell for under all of the following conditions:
Market value is what a property *should* sell for under normal conditions — it is an estimate, not a guarantee.

Understanding the distinctions between related value concepts is heavily tested on the California exam.
Market value is the estimated price the property *should* sell for under typical conditions (an appraiser's opinion). Market price is the actual price the property *did* sell for in a specific transaction.
These can differ significantly. A distressed sale (divorce, foreclosure, estate) may produce a market price well below market value. A competitive bidding war in the Bay Area may produce a market price above market value.
California Proposition 13 (1978) fundamentally changed how property is assessed in the state. When a property is purchased, it is reassessed at the purchase price (the new base year value). The assessed value can increase by a maximum of 2% per year, regardless of actual market appreciation. When the property is sold again, it is reassessed at the new sale price.
Result: A San Francisco home purchased in 1998 for $450,000 may have an assessed value of approximately $650,000–$700,000 (after 26 years of 2% annual increases), while its current market value might be $2.5M or more. The property tax bill is based on the assessed value, not market value.
Supplemental assessment: When a property is sold, the county issues a supplemental assessment adjusting the base to the new purchase price. New owners receive a supplemental tax bill for the difference.
Appraised value is a licensed appraiser's formal, written opinion of market value at a specific point in time, using USPAP methodology. Appraised value and market value are theoretically the same concept — but appraisals can lag the market, especially in rapidly changing California markets.
Listing price is the price at which a seller chooses to list the property — set by the seller, often with agent input via CMA. In California's competitive urban markets, listing prices are often intentionally set below market value to attract multiple offers, drive a bidding war, and ultimately achieve a sale price above the listing price.
Loan value (also called lending value) is the amount a lender will loan against a property, typically based on the lower of the appraised value or the purchase price. LTV (Loan-to-Value ratio) = Loan amount ÷ appraised or purchase value (whichever is lower).

Several economic and market principles drive how properties are valued. These principles are tested on the CA exam and underlie all three appraisal approaches.
Value is determined by the interaction of supply and demand. When demand for homes in a neighborhood exceeds supply (as in most Bay Area submarkets), prices rise. When supply outpaces demand (as occurred in the Inland Empire in 2008–2010), prices fall.
A buyer will not pay more for a property than the cost of acquiring an equally desirable substitute. This is the foundation of the sales comparison approach — buyers compare alternatives. A home priced above its substitutes will not sell.
The value of any component of a property is measured by how much it contributes to the total value — not by its cost. A $100,000 pool addition may only contribute $30,000 to market value if buyers in that neighborhood do not value pools highly.
This is why appraisers use market-derived adjustments (what buyers actually pay for features) rather than cost-based adjustments.
Value is maximized when a property conforms to the standards of its neighborhood. An over-improved property (the most expensive home on the block) suffers from regression — its value is pulled down toward the neighborhood average. An under-improved property (smallest home in a luxury neighborhood) benefits from progression — its value is pulled up toward the neighborhood average.
The highest and best use is the use that is:
Appraisers must determine the highest and best use of the land as though vacant, and then the highest and best use of the property as improved. A deteriorated commercial building in a high-density zoned urban core may have a highest and best use of redevelopment — making the improvement value negative (the building actually reduces total property value by the cost to demolish it).
Value reflects the anticipated future benefits — income, appreciation, utility — that a property is expected to provide. Buyers in Silicon Valley pay premium prices in part because they anticipate continued appreciation. This principle underlies the income approach (capitalizing future income streams into present value).
California example: A modest fixer-upper on a street of $3M Atherton estates may sell for significantly more than it would in a comparable neighborhood of $1.2M homes.
Real estate markets are not static. Values change constantly in response to economic conditions, demographic shifts, neighborhood development or decline, and interest rate movements. Appraisers must account for time adjustments in the sales comparison approach — a comparable that sold 12 months ago may need a positive or negative time adjustment if the market has moved significantly.
When combining smaller adjacent parcels creates a larger, more valuable parcel, the resulting value is greater than the sum of the individual parcel values. This increment in value is called plottage value (or assemblage value). It is relevant in commercial and development transactions.

Quiz Questions:
Q1. A San Jose homeowner purchased her home in 2005 for $650,000. She has never made any major improvements. Today, comparable homes in her neighborhood sell for $1.8M. Under California Proposition 13, approximately what is her assessed value today (assume 2% annual increase for 20 years)?
A) $1,800,000 — assessed value equals current market value B) $650,000 — assessed value never changes after purchase C) Approximately $967,000 — the original purchase price compounded at 2% per year for 20 years D) $1,300,000 — halfway between purchase price and current market value
Answer: C — Under Prop 13, the assessed value is the purchase price increased by up to 2% per year. $650,000 × (1.02)^20 ≈ $967,000. The assessed value grows far more slowly than actual market values, resulting in a large gap in California's appreciating markets.

Q2. A homeowner spends $80,000 to add a custom home theater to her Burbank property. After the renovation, comparable homes with similar theaters in the neighborhood sell for only $30,000 more than comparable homes without them. What principle explains the difference between cost and value?
A) Substitution — buyers will simply buy a different home without the theater B) Contribution — the feature's value is measured by what it adds to market value ($30,000), not what it cost ($80,000) C) Regression — the theater has pulled down the home's overall value D) Anticipation — buyers do not expect the theater's value to increase in the future
Answer: B — The principle of contribution states that the value of any component equals its contribution to total value, not its cost. The $80,000 investment contributed only $30,000 to market value — the remaining $50,000 was not recouped by the market. This is a common finding in renovation analysis.

Q3. A property in downtown Los Angeles is currently improved with a 50-year-old two-story office building generating modest rents. The site is zoned for 20-story high-density mixed-use development. An appraiser would most likely conclude that the highest and best use is:
A) Continued use as a two-story office, because the existing improvement is income-producing B) Redevelopment as a high-density mixed-use building, because that produces the maximum value as a vacant site C) Conversion to residential condominiums, because housing demand is always the highest use in California D) Demolition and surface parking, because parking generates immediate income with low carrying costs
Answer: B — Highest and best use analysis requires evaluating the site as though vacant. If zoning permits 20-story mixed-use development, and that use is financially feasible and maximally productive, it is the highest and best use. The value of the existing old office building may actually be negative (it would need to be demolished), and the land value itself reflects the redevelopment potential.

Q4. A buyer pays $2,200,000 for a home in a neighborhood where comparable homes sell for $1,900,000–$2,100,000. The buyer was under pressure to move quickly for a job relocation and paid above market to secure the deal. Which statement is most accurate?
A) The market value of the home is now $2,200,000, because that is what a buyer paid B) The market price was $2,200,000, but market value may still be in the $1,900,000–$2,100,000 range, because the transaction did not occur under typical conditions C) The appraiser must use $2,200,000 as the market value because an arm's-length sale occurred D) The sale price has no relevance to market value
Answer: B — Market value requires typical motivation and no undue pressure. A buyer who paid above comparable sales because of time pressure did not transact under typical market conditions. The market price ($2,200,000) differs from market value. An appraiser would note the atypical motivation and may not use this as a primary comparable.

Q5. A small, modest bungalow is located in a neighborhood of large, well-maintained luxury homes in Pasadena. The bungalow is likely to sell for more than it would in a comparable bungalow-dominated neighborhood. Which principle explains this?
A) Regression — the large homes are pulling the bungalow's value down B) Conformity — the bungalow conforms to neighborhood standards C) Progression — the lower-value property is pulled upward by proximity to higher-value properties D) Contribution — the luxury features of neighboring homes contribute directly to the bungalow's value
Answer: C — The principle of progression states that a lower-value property benefits from being surrounded by higher-value properties — its value is pulled upward toward the neighborhood norm. The opposite (regression) applies when a high-value property is surrounded by lower-value properties.
