What Is an Appraisal?
An appraisal is an independent, professional estimate of what an asset is worth at a particular moment. It most often refers to real estate, but appraisals are also used for businesses, equipment, art, collectibles, and other property that does not trade on a public exchange with a clear, current price. The person who prepares the estimate is called an appraiser, and the written document that reports the conclusion is the appraisal report.
How an Appraisal Works
An appraiser inspects the property, gathers relevant data, and applies one or more recognized valuation approaches. For real estate, three common approaches are:
- The sales comparison approach, which compares the property with similar properties that recently sold nearby, adjusted for differences in size, condition, and location.
- The cost approach, which estimates the cost to rebuild the structure new, subtracts depreciation, and adds the value of the land.
- The income approach, which estimates value from the income the property could generate, often using a capitalization rate or a discounted cash flow analysis.
The appraiser then reconciles these results into a single opinion of value. That conclusion is an opinion, not a guarantee of the price a buyer would pay. In many countries, appraisers must be licensed or certified, follow established professional standards, and remain independent of the parties with a financial stake in the transaction.
Why Appraisals Matter to Investors
Appraisals are useful whenever a price must be set without a market quote. Lenders commonly require one before approving a mortgage to confirm that the property is worth at least the loan amount, a relationship measured by the loan-to-value ratio. Appraisals also support fair value reporting for assets held by funds or companies, and they are used to value private businesses in estate planning, divorce settlements, and some shareholder disputes. In mergers, the term "appraisal rights" refers to a shareholder's ability to ask a court to determine the fair value of shares when they object to a deal.
An appraisal is not the same as a home inspection, which examines physical condition, and it is not the same as a market price. Appraised values can differ from eventual sale prices, and they become less reliable when market conditions change quickly.
Advantages and Limitations
Appraisals provide an independent, documented view of value for transactions that might otherwise rely only on the opinions of the buyer and seller. The resulting report also gives lenders, auditors, and courts a standard record to review.
The main limitation is that an appraisal is an estimate built on assumptions and comparable data. Two competent appraisers can reach different figures for the same asset, and thin markets with few recent sales make estimates less dependable. Reviewing the report's stated assumptions and effective date helps readers judge how much weight the final number deserves.
