The median owner-reported home value in SeaTac is $483,200.
That is 40% below the King County median of $811,200. Median household income is $76,517, 37% below the county's $122,148.
SeaTac's housing is genuinely mixed - 43.7% detached houses, 48.4% in multi-unit buildings, and 2.7% attached single-family such as townhomes. Both house and attached-home stock exist here in real numbers.
45.1% of occupied homes are owner-occupied - a fairly even ownership-to-rental split.
Half of SeaTac's homes were built in 1971 or earlier, so a large share predates modern energy codes - worth leaving time in the inspection for the roof, the electrical, and the plumbing.
5.2% of housing units are manufactured or mobile homes, which typically signals available acreage and a live land market in and around SeaTac.
