01What the evidence says this house is worth

ALEX AI Statistical Model

Minimum

$390,942

Average

$417,312

Median

$412,190

Maximum

$450,753

ALEX’s statistical model uses five comparable sales. Each sale’s adjusted price is carried to this home’s 2,104 SF using the size effect measured from these same sales. Each sale is then weighted by how closely it matches this home on size, age, lot, rooms, distance and date of sale. The average and median are weighted; the minimum and maximum are the lowest and highest single sale.

Traditional Arithmetic Model

Minimum

$407,593

Average

$448,080

Median

$450,262

Maximum

$484,299

The same five sales with the same adjustments, each scaled to this home’s size at its own price per SF and counted equally. Section 02 explains how the two rows differ.

02How the two rows differ

What the two rows share. Both rows start from the same five sales and carry the same adjustments: the market trend from each sale’s date to today, the feature adjustments ALEX calculated, the changes and additions Diane made after comparing each sold home with this property, and scaling to this home’s size at each sale’s own price per SF.

Where they differ. The statistical model makes two further corrections. First, it applies a size adjustment measured from these sales, because price per SF falls as homes get larger. Second, it gives each sale a weight based on how closely it matches this home, where the traditional row counts every sale equally. The “Size adjustment” and “Final valuation” tables below show both corrections sale by sale, and the detailed report sets out the full method.

Compared on the average alone, ALEX’s valuation is lower than the traditional arithmetic figure. The difference is shown below in dollars and as a percentage of the traditional average.

With VA financing, the VA appraisal, not the asking price, is the value that matters. The VA assigns the appraiser, and the appraised value is issued as a Notice of Value.

This offer’s net to the seller, shown above, is inside the ALEX AI Statistical Model’s range of $390,942 to $450,753. It is below the model’s average of $417,312 and also the Traditional Arithmetic Model’s average of $448,080. Both rest on the five closed sales summarized below. The VA appraiser will form an independent opinion from the same kind of evidence. These sales are the case that can be put in front of the appraiser; they are not a prediction of what the appraiser will conclude. Diane will guide the strategy with you.

One condition remains: the Notice of Value. If the Notice of Value comes in below the contract price, the VA amendatory clause lets you choose: make up the difference in cash, or terminate the contract and have your earnest money returned. The ceiling in section 04 marks the most the evidence supports, not the most the loan allows. You decide which counter to use and when, or whether to counter at a different price.

Five other properties are for sale in Sierra Vista, asking $285,000 to $388,000. They are context, not evidence. An asking price is a seller’s opinion of value. None has sold, and no active listing is used in the valuation.

04If the seller counters on the $8,000 credit

Move the price, not the credit. Because you are financing 100% with no down payment, the seller-paid closing costs help you close the VA purchase. Giving them up raises the cash you must bring to closing. If you need to offer more, raise the contract price and keep the full credit in place.

Every counter in the table below keeps the full credit, and we recommend that any counter you make does the same.

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 request.
Split the difference	$422,600	$8,000	$414,600	Net to the seller about halfway between the current offer and the model average, rounded down to the nearest $100.
Ceiling	$425,300	$8,000	$417,300	Net to the seller equals the model average, rounded down to the nearest $100. Above this, you would be paying more than the evidence supports.

Total size adjustment	—	+$17,058	+$51,698	+$43,883	+$43,334	+$16,863

Scaling to 2,104 SF. Every home that sold is smaller than this one. To compare them fairly, each sale’s price is first restated at this home’s size, using the sale’s own price per SF. For example, 312 Susana Dr has 1,960 SF, and its price after the time adjustment and all feature adjustments, including any made by Diane, is $419,446. Restated at this home’s size: $419,446 × 2,104 ÷ 1,960 = $450,262. The scaling line for 312 Susana Dr is the difference, +$30,816.

Statistical size adjustment. Scaling at a sale’s own price per SF assumes that price per SF stays the same as size changes. It does not. Smaller homes usually sell for more per SF than larger ones, because every home has a kitchen, bathrooms and a lot, and those cost about the same whatever the home’s size. Scaling alone therefore overstates the value of a sale smaller than this home and understates the value of a larger one. ALEX measured, from these five sales, how price per SF changes with size, and applies that correction to each sale. For 312 Susana Dr the statistical size adjustment is −$13,758, so its total size adjustment is +$17,058. The further a sale’s size is from this home’s, the larger the correction.
