Why the model sees it this way
Sialim's model forecasts the typical Seattle home value will fall 0.4% in July 2026, from $745,263 to about $742,326. The 80% confidence range runs from $741,022 to $743,072.
Prices have been slipping, down an average of 0.68% per month over the past three months, and the market is down 1.8% from a year ago.
The 30-year mortgage rate sits near 6.5% (elevated for affordability); for-sale inventory is up 18% year over year, which adds downward pressure on prices; national unemployment is 4.2%. For this metro the price-only model outperformed the macro-augmented one in backtesting, so the forecast leans on the price trend itself.
Over the most recent six-month test window, this model's predictions for Seattle were off by 1.9% on average. Smaller is better; anything under 1% is strong for monthly home values.
