What the numbers mean for a buyer or seller
The median owner-reported home value in SeaTac is $483,200.

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.
SeaTac is 31,143 people, big enough for a steady flow of comparable sales. Vacancy sits at 5.2%.
5.2% of housing units are manufactured or mobile homes, which typically signals available acreage and a live land market in and around SeaTac.
Selling in SeaTac
SeaTac runs close to an even split - 45.1% of occupied homes are owner-occupied - so your buyer could as easily be a family moving in as someone buying to rent it out. Pricing and presentation have to work for both.
For pricing context, the midpoint of SeaTac homes is $483,200, and the area sits about 4.1 miles off the Seattle-Bellevue-Tacoma spine - usually the first thing a buyer's agent checks when they push back on a list price.
Half the homes here were built in 1971 or earlier, so buyers and their inspectors arrive expecting questions about the roof, the electrical and the sewer line. Knowing those answers before you list is usually worth more than fixing them mid-negotiation.
A large share of SeaTac's housing is in multi-unit buildings, so if you are selling a condo the comparison set is genuinely different from a detached house and should be priced against the right one.
Isaac will tell you what your home is actually likely to bring in SeaTac and what, if anything, is worth doing first. If the honest answer is that this is not your year to sell, he will say that too.
