Desktop date of death appraisals, retrospective appraisals, probate appraisals, estate appraisals, and stepped-up basis valuation support for inherited property in San Mateo, San Mateo County.
A San Mateo date of death appraiser determines the fair market value of real estate as of a specific prior effective date, most commonly the date of death. A date of death appraisal in San Mateo is often needed for probate, estate settlement, trust administration, IRS reporting, inherited property valuation, and stepped-up basis documentation.
Whether you are looking for an estate appraisal in San Mateo, a probate appraisal in San Mateo, or a retrospective appraisal in San Mateo, the purpose is to develop a well-supported opinion of value based on market evidence from the effective date, not simply current market conditions.
Date of death appraisals in San Mateo require more than pulling recent sales. The analysis may include historical MLS data, prior listings, public records, comparable sales activity, neighborhood trends, property condition, lot utility, location influences, and market conditions that existed as of the retrospective effective date.
My appraisal process emphasizes comparable sales research, market-supported analysis, and market-extracted adjustments through paired sales when the available data supports that level of analysis. This is especially important when two properties appear similar on paper but compete differently due to condition, location, size, age, floor plan, site utility, view influence, or neighborhood segment.
For inherited property, estate settlement, probate, trust administration, and stepped-up basis reporting, the appraisal should reflect how buyers would have reacted to the property as of the date of death, not how the market appears today.
