 We haven't heard this in a while. Seattle area housing prices are down slightly. The median single-family home in King County sold for $965,000 last month. That's down from the record-breaking $1 million-plus median home price in May. But it's still 3% higher than the median home price in June of last year. Home prices are highest on the east side still, where a median single-family home is selling for more than $1.6 million.
