01What the evidence says this house is worth

ALEX’s statistical model uses five comparable sales. Each sale is carried to this property’s 2,104 SF 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. How and why the two rows differ is explained below.

02How the two rows differ

Compared on the average alone, ALEX’s valuation is $30,768 lower than the traditional arithmetic figure — 6.9% lower. The percentage is measured against the traditional average, the figure most readers would reach for first.

Both averages are built from the same five sales with the same adjustments, Diane’s included, and both are net sale prices. The only thing that separates them is how each sale’s smaller size is carried to this house’s 2,104 SF, which section 03 explains. Every sale and every adjustment is laid out in section 06, the summary of comparable properties. The lower figure is the one the sales support once size is priced the way this market prices it.

03Why the two rows differ

Every one of the five comparables is smaller than this house. They run 1,652 to 1,960 SF against this property’s 2,104. A smaller house sells for fewer dollars but more dollars per SF, so averaging their per-SF rates and applying that rate here lifts the answer by the difference shown in section 02. The statistical model fits the size relationship from the sales themselves and carries each one to 2,104 SF 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.

The financing makes the VA appraisal, not the asking price, the number that governs. A VA-guaranteed purchase is appraised by an appraiser the VA assigns, who issues a Notice of Value. Where that notice comes in below the contract price, you can make up the difference, or you can terminate the contract and get your escrow money returned.

What this report can say about that appraisal is what the sales support. Five closed sales in Sierra Vista set the net evidence, and this offer nets the sale price to $411,900. This is inside the range of $390,942 to $450,753, and below the average of the ALEX AI Statistical Model ($417,312) and the average of the Traditional Arithmetic Model ($448,080). The VA’s appraiser will form an independent opinion from the same kind of evidence; this is the case that can be put in front of them, not a prediction of what they will write. Diane will guide the strategy with you.

Six other properties are for sale in Sierra Vista’s wider market, asking $390,000 to $675,000. They are context, not evidence: an asking price is a seller’s opinion of value, and none of them have sold. No active listing enters the valuation.

05If the seller counters on the $8,000

Move the price, not the credit. Because you are financing 100% with no down payment, that $8,000 of seller-paid closing costs helps make the VA purchase closable. Trading it away creates a higher cash requirement for you at the closing table. If necessary, raise the contract price and keep the $8,000 credit intact.

Every suggested counter keeps the full $8,000 credit for you at closing. No matter how you counter, consider always including the full $8,000 credit.

Counter	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	$422,600	$8,000	$414,600	Half the room between here and the model average.
Ceiling	$425,300	$8,000	$417,300	Net lands just under the model average. Past this you would be paying more than the evidence supports.

One gate remains: the Notice of Value. If the VA appraiser comes in below the contract price, you can make up the difference if you want, or you can terminate the contract and get your escrow money returned. The ceiling above is about what to concede willingly, not about what the loan will permit. You control which counter is used and when, or if you want to counter at a different price.

A row marked Diane revised is one where she changed the AI’s figure for at least one sale; her figures are in bold, and 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 SF. The row with AI & Diane’s adjustments holds the five figures behind the Traditional Arithmetic row in section 01. The size adjustment then corrects for the fact that every sale is smaller than this house: smaller houses sell for more per SF, so applying a smaller house’s rate to 2,104 SF overstates the value. The statistical model measures how much the rate falls as size rises, from these sales, and takes that amount, per SF, off each indicated value. The result is the final adjusted value, which, weighted by how alike each sale is to this house, gives the ALEX AI Statistical row. Every dollar figure is rounded to the whole dollar where it first appears, every total is the sum of the lines above it, and rates and weights are used exactly as shown.
