The bars run from zero, so the cut reads at its true size: 3.4% is a modest reduction, and a chart with a cropped baseline would make it look like a collapse. The hatched cap on the original bar is the $19,000 that came off.

What this says

The asking price sits $16,298 above the evidence

Three closed sales inside Serenada West, each adjusted to this property across 66 factors and to today's market, place it at $523,702. That is a net figure — what a seller keeps after covering buyer closing costs and repair credits — which is the basis every number on this page uses.

The $540,000 list is 3.1% above that, and inside the supported range. This is not a report saying the house is mispriced; it is a report saying where the evidence sits and how firmly.

Where everything is

The subject, its comparables, and what it competes with

All three comparables lie within half a mile, inside the same subdivision. Click any red marker to jump to that sale in the table below.

4319 Miramar Drive — the subject Comparable used (click to jump) Active listing, not used

Rings mark quarter-mile, half-mile and one-mile from the subject. The two active listings are both around 22% larger than this house, past the size tolerance, so neither is a comparable — but they are what a buyer looking at this property will also be seeing.

One note on the competition set: 300 W Sequoia Spur is currently counted twice — once at its $509,999 asking price and once at $2,700, which is a monthly rent. A lease is not a sale competitor. It was excluded on size either way, so it did not affect the valuation, and the duplicate is recorded as a defect to fix.

How firm is it

Measured on this property, not on a market average

Every figure below is computed from this property's own comparable set. Plain meaning first; the technical definition sits beneath each one.

Hiding each comparable and re-predicting it from the other two, the method is off by about this much. 6.2% Leave-one-out back-test, mean absolute error. Each sale is held out and re-predicted by the rest, re-running all 66 adjustment factors. On $523,702 that is roughly ±$32,500.
How much the three comparables disagree with each other once adjusted to this house. 10.8% Adjusted spread. Highest adjusted comparable against lowest, as a share of the estimate. Tight agreement; a wide spread would mean the middle of it was not a better answer than its edges.
How far the engine had to move these houses to make them comparable to this one. ±3.2% average Mean absolute adjustment. Small adjustments mean the comparables were genuinely alike to begin with. The largest single adjustment in this set is $25,998.
Half these sales closed longer ago than this. 145 days Mean comparable age. Serenada has given back its 2025 rally — $257.62/sf in the first half of 2025 against $226.44 now — so older sales are discounted explicitly by the market-timing factor rather than carried forward unchanged.

Median of the three adjusted values — range $497,057 to $553,814, spread 10.8% $523,702

Adjustments apply to net sale price — close price less seller-paid buyer closing costs and seller repairs — which is why the arithmetic runs off the Net column. Adjusted value = net + adjustment, and the indicated value is their median.

Two sales were rejected, and why

A sale more than ±20% from the asking price is not a comparable. The rule is absolute and applies before any other test. On a $540,000 list that band is $432,000 to $648,000, measured on net.

Removing them tightened the result rather than weakening it: the spread across the comparables fell from 24.5% to 10.8%, back-test error from 7.3% to 6.2%, and the search settled on closer matches. No comparable was drawn from an age-restricted community, none carries an HOA this property does not have, and none is this property's own prior sale.

Land is priced at this parcel's own Williamson CAD rate — $124,254 across 23,087 square feet, or $5.38 per square foot — not a county average and not a third-party record. The county roll reconciles for every year on file: land plus improvement equals total.

Limits

What this is, and is not

Please read

This is a comparable-sales opinion of value, not a certified appraisal, and it is not a mortgage or lending document. It is produced from the ABOR feed, Williamson CAD records and ALEX's own adjustment engine, run automatically with no comparable selected by hand. Three comparables is the minimum from which a range can honestly be quoted — the set here is tight and consistent, but it is three sales, and a market this thin deserves that said plainly rather than buried.
