There are definitely 3 bedroom places that would go for $550K near SeaTac, too, but the difference is that here there are *also* at least some 3 bedroom houses still available for under $300K, depending on how directly-under-the-flight-path you're willing to go, and how much you're willing to fix. One of the places we've largely not looked at all is directly under the approach to SeaTac, also not the corridor under the typical take-off pattern.
