NWMLS King County Housing Market 2025: Single-Family vs. Condo Trends

Single-Family Homes: More Supply, Stable Prices

King County’s single-family housing market saw a significant inventory expansion in 2025. Active listings increased nearly 42% compared to the prior year. New listings also rose more than 10%.

However, closed sales declined 2.9%. Therefore, higher inventory did not translate into higher transaction volume. Even so, prices remained resilient. The median single-family home price increased 2.6% year-over-year, finishing just below $975,000.

Months of inventory generally ranged from 1.5 to 2.8 months. As a result, the market softened but remained seller-leaning.

Condominiums: Greater Balance Emerges

Condominiums followed a different trajectory. Active condo inventory increased almost 40%, and new listings rose 12%. Unlike single-family homes, condo closed sales increased 4.5%.

Median condo prices increased 1.8%, ending the year near $560,000. Meanwhile, months of inventory ranged between 2.8 and 4.6 months. Consequently, condo buyers gained noticeably more negotiating leverage.

Luxury Market Concentration

Luxury single-family home sales remained heavily concentrated on the Eastside, which accounted for 72% of all $2 million-plus transactions. Seattle represented roughly 24%, while other areas contributed minimal volume.

What This Means

Overall, 2025 marked normalization. Single-family homes retained pricing strength. Condos moved closer to balance. Therefore, market strategy increasingly depends on property type rather than broad headlines.
