Fairfield’s median rose 23.6%. The same-house measure rose 8.7%.

The median sale is the middle price of the year’s single-family sales. Same-house change follows properties that sold more than once, so a shift toward larger or newer houses does not drive that measure in the same way. A shift toward larger or newer houses can lift the median faster than the same-house measure; the gap alone does not measure how much of the change came from that shift.

The sale mix matters

Fairfield recorded 570 single-family sales in 2025, with a median of $1.13M and a reported price per square foot of $518. Those figures describe the completed sales in that year. They do not assign the median to every neighborhood, price a specific house, or establish what an unsold listing is worth.

If one year contains more substantial houses, its middle sale can move higher even without an equivalent change in the value of each home. This is why the 23.6% headline should not become a blanket adjustment to last year’s comparable sales.

The 8.7% repeat-sale result answers the narrower market-movement question. It still does not account for every distinction between two houses. An enlarged home, an unrenovated house and a new build require separate scrutiny of condition and improvements.

Longer comparisons need their own labels

Fairfield’s median was up 77.2% from 2016. After inflation—adjusted with the consumer price index—the increase was 32.0%. Its same-house measure was 3.3% above the 2006 peak after inflation.

These are three comparisons with different starting points or methods. None should be described simply as “what Fairfield homes have returned.” A sale-price series also leaves out financing, carrying costs, work on the property and the cost of buying or selling.

Use the right number for the decision

An owner preparing to sell needs recent comparable transactions, with attention to usable area, lot, condition and location. The median establishes the level of the annual market; the repeat-sale measure helps explain its movement. Neither substitutes for the comparable set.

A buyer can use the same distinction when evaluating a house priced well above a previous sale. Ask what changed at the property, which transactions support the current asking price, and whether a market-wide median is being asked to do work it cannot do.

The Fairfield page supplies the local setting. The Connecticut Index supplies consistent comparisons across the measured areas. In 2025, both measures rose; the median’s +23.6% and the same-house measure’s +8.7% describe different parts of that market.
