Step 1 · Comparable sale selection

Selected by Diane Hart Alexander. ALEX’s selection rules were not applied; every sale entered was used as entered and adjusted the same way.

Step 3 · Valuation

ALEX Model vs. BVBOR CMA

The ALEX Model is unique in both comparable selection and precision valuation.

Steps: 13× a BVBOR CMA. The ALEX Model values a home in 26 steps across 4 stages, shown below (sometimes the agent picks or changes the sales). A BVBOR CMA adjusts only for basics like beds, baths, SF and lot size, then values the home at the average sold price per SF times its SF.

Variables. The ALEX Model compares over 60 variables.

BVBOR CMA: only adjustments are to property information. Each sale's avg. price per SF × this home's SF. The ALEX Model nets out seller concessions, brings each sale to today, adjusts it for every measured difference, corrects for size and weights it by how closely it matches. Here the ALEX Model is $5,552 (1.2%) higher.

ALEX’s index: built from homes that sold more than once, so a change in what sold does not read as a change in prices.

Automated estimates use public records and broad statistics; they do not see this home’s comparable sales or their concessions. A county value is set for taxes as of January 1.

This is a comparable-sales opinion of value. It is not a certified appraisal and not a mortgage or lending document. Sale prices are net of seller-paid closing costs and buyer-requested repairs, adjusted to today with ALEX’s index. Sale and listing data: BVBOR MLS reports supplied by the agent. Tax values: the county appraisal district where available.
