Why Condition Moves Value More Than Square Footage
Two identical floor plans on the same street can close $60k apart. The difference is not in any public record.
Public property records know a home's bedrooms, bathrooms, square footage, lot size, and year built. They do not know whether the kitchen was renovated last year or last touched in 1987.
Yet that missing fact, condition, routinely moves price more than an extra bedroom does. Two identical floor plans on the same street can close $60k apart, and nothing in any public record explains why.
The same house, two prices
Take two copies of the same floor plan on the same street. One has a renovated kitchen, updated baths, and new flooring. The other is clean but original.
| What you check | Renovated copy | Original copy |
|---|---|---|
| Beds, baths, square footage, lot, year built | Same | Same |
| Kitchen | Renovated last year | Last touched in 1987 |
| Baths and flooring | Updated, new | Clean but original |
| What a public record sees | Identical | Identical |
In most markets those two homes close far enough apart that using one to price the other, without an adjustment, wrecks the estimate. A model that reads only public records is forced to treat them as identical, so it averages. The average is wrong about both: high on the dated one, low on the renovated one.
| Closing gap, renovated copy vs original copy | $60,000 |
| What a record-only model serves for both | the midpoint |
| Miss on the original copy, priced high | $30,000 |
| Miss on the renovated copy, priced low | $30,000 |
Half the condition gap lands on every estimate as built-in error before the model makes a single mistake of its own.
Why investors get hit hardest
Investors live at the extremes of condition. You buy the dated house and sell the renovated one, which means the properties you care about are exactly the ones record-based estimates price worst.
An estimate that is excellent on move-in-ready suburban homes can still be badly off on the fixer you are bidding, and the miss runs in the direction that costs you: over-valuing rough condition. The model is averaging your fixer toward its tidier neighbors, so the number it hands you belongs to a house that does not exist.
Reading condition from photos
The information exists. It is sitting in the listing photos. Resideline grades condition from photos on both the subject and its comps, then matches like to like: dated subjects against dated closings, renovated against renovated.
When you review any comp set, run the same check by hand.
Open the photos
For the subject and for every comp. Condition lives in the photos, not in any field a record-based model can read.
Look at kitchens and baths specifically
They are where condition shows first, and where the gap between renovated and original is widest.
Match state to state
Ask whether this comp's condition matches the state you are pricing: the state you buy in, or the state you will sell in.
Run a CMA on a dated property and look at the condition grades on its comps. Then price it twice in your head: as-is against the dated comps, finished against the renovated ones. That spread is your project, in dollars.
