A Scottsdale stepped-up-basis appraisal should document the historical real-estate value cleanly and leave tax treatment to the taxpayer's advisers. Luxury and custom properties may have few close historical matches. The appraiser develops the real estate value opinion; the taxpayer and tax professionals determine the applicable basis treatment.
The appraiser's role is to develop a supported fair market value for the applicable historical date. The taxpayer, CPA, attorney, or other adviser determines how that value is used for basis and tax reporting. For Scottsdale, the appraisal should consider custom/luxury only when it changes the subject's competitive position.
In a stepped-up-basis appraisal, luxury and custom properties may have few close historical matches. The search may need to expand geographically while remaining strict about quality, architecture, renovation level, lot utility, outdoor improvements, and buyer profile. For stepped-up-basis support, the question is whether the feature affected fair market value on the applicable historical date.
The appraisal should support the real estate value on the applicable historical date. It does not calculate capital gains, determine the taxpayer's basis election, or replace advice from a CPA or attorney.
Historical listings, condition evidence, ownership records, permits, and later improvement documentation can help support the earlier fair market value. That evidence helps document the real estate value independently of whatever tax treatment is later applied.
A stepped-up-basis appraisal should document the property and market evidence clearly enough that the historical fair market value can be understood later, even if the property is sold or changed afterward.
