The ALEX Model uses 45 variables in this valuation, 32 more than the 13 adjustments in the Austin MLS CMA, which leaves the choice of sales to the realtor and makes no time adjustment. The CMA counts Subdivision among its 10 features; the ALEX Model uses it to choose the sales (1.2). Every ALEX feature adjustment is priced at what ABOR closed sales show the market pays. Each variable counts once in each step it is used in. 9 of the feature adjustments changed at least one sale’s value here. 9 more feature lines were tested on ABOR sales in this price range, showed no measurable price difference, carry $0 and are not counted. Lines an agent adds (3.6–3.7) are not counted.
