ALEX · Executive Summary · Draft
Comparable-sales valuation · Listed Property Buyer Model · Williamson County
ALEX’s statistical model, over five comparable sales. Each sale is carried to this property’s 2,104 square feet on the fitted size relationship, then weighted by how near it is to this house in the matching metric.

The same five sales counted equally, without carrying them to this house’s size. Why the two rows differ is below.
Every one of the five comparables is smaller than this house. They run 1,652 to 1,960 square feet against this property’s 2,104. A smaller house sells for fewer dollars but more dollars per foot, so averaging their per-foot rates and applying that rate here lifts the answer by about $30,000. The statistical model fits the size relationship from the sales themselves and carries each one to 2,104 feet before it counts — which is the whole of the difference between the two rows. The arithmetic figures are shown so that difference can be seen rather than taken on trust.
All five are in Sierra Vista, the subject’s own subdivision. Each column is one house, this one first. Every adjustment is shown at its final figure. A row marked Diane revised is one where she changed the AI’s figure for at least one sale, and her figures are in bold; the lines she added are listed separately. Size is not a dollar line: each sale’s adjusted price is divided by its own living area and applied to 2,104 square feet. The row with Diane’s adjustments is the Traditional Arithmetic row above, and the carried row, weighted, is the ALEX AI Statistical row; the AI only row shows where the sales stood before her changes.

An offer of $419,900 has been made — the full asking price — with $8,000 of the buyer’s closing costs paid by the seller. Every figure in this report is a net sale price, what the seller keeps once any such contribution is taken out, so the offer belongs on that same basis: $411,900. That is the number to read against the two rows above.

Move the price, not the credit. For a buyer financing 100% with no down payment, that $8,000 is not a discount — it is the mechanism that makes the purchase closable, and part of it covers costs a VA buyer is not permitted to pay. Trading it away creates a cash requirement at the closing table that, by the structure of this loan, there is no cash set aside to meet. Raising the contract price while keeping the credit intact gives the seller the same thing they are asking for — a larger net — without moving that problem onto the buyer.
Every rung below keeps the full $8,000 and holds the net at or under the model’s own average, so nothing here asks the buyer to pay more than the sales support.
| Rung | Contract price | Seller credit | Net to seller | What it concedes |
|---|---|---|---|---|
| Where it stands | $419,900 | $8,000 | $411,900 | Full asking price; the credit is the only ask. |
| Split the difference | $424,000 | $8,000 | $416,000 | Half the room between here and the model average. |
| Ceiling | $428,100 | $8,000 | $420,100 | Net lands just under the model average. Past this the buyer is paying more than the evidence supports. |
