Owner-Occupied Value Versus Market Price: Two Different Numbers

The home value in census data is an opinion, collected from owners. It is not an appraisal, not a listing and not a recorded sale. That makes it very good at describing the whole stock of owned homes and less good at tracking where buyers are paying today. This article explains how the two numbers differ, why each has a place, and how to avoid mixing them.

Census home values are owner estimates covering all owner-occupied homes, including ones that rarely or never sell.
Market prices come from transactions and reflect only homes that actually change hands in a period.
The two often move in the same direction, but their levels and timing differ, so they should not be swapped.

Where each number comes from

Owner-occupied value is what a household says its home would sell for, asked in a survey. Market price is what a buyer and seller agreed to in a closed transaction. One is a belief, the other a deal. Beliefs can be informed by neighbors' sales, but they can lag, overshoot or round.

Coverage differences

Survey values cover every owner-occupied home that is surveyed, including houses held for decades. Sale prices cover only the small share of homes that sell in a given period, and that share can skew toward newer, pricier or more distressed properties. Each therefore describes a different subset of the housing market.

Timing and smoothing

Owners adjust their estimates slowly, so survey values usually lag fast-moving markets, rising later and falling later than sale prices. Multi-year pooling adds further smoothing. Sale prices react quickly but jump around with the mix of homes sold. Different tools suit different questions about the same market. Appraisers and agents use fresher evidence for individual homes.

Why survey values still work for affordability

For comparing thousands of small places, coverage and consistency matter more than speed. Survey values exist for nearly every area, use one definition and pair naturally with survey income. The comparison is therefore internally consistent, even if the absolute level differs from what a buyer would pay today. That is a practical reason this approach scales to the whole country.

Using each number honestly

Describe survey-based figures as estimated values, and sale-based figures as prices. Do not place them in one table. If a decision requires knowing what a particular home would fetch now, use local comparable sales and a professional appraisal. The area ratio can say where to look, not what a given house is worth. Labeling your sources keeps comparisons honest.
