Why the model sees it this way
Sialim's model forecasts the typical Grants Pass home value will hold near flat in September 2026, from $390,436 to about $390,373. The 80% confidence range runs from $390,119 to $390,914.
Prices have been close to flat over the past three months (+0.09% per month on average), and the market is up 0.1% from a year ago.
The 30-year mortgage rate sits near 6.7% (restrictive for affordability); for-sale inventory is about even with a year ago (-2%); national unemployment is 4.1%. These conditions feed into this metro's forecast, since the macro-augmented model beat the price-only model in backtesting here.
Over the most recent six-month test window, this model's predictions for Grants Pass were off by 0.2% on average. Smaller is better; anything under 1% is strong for monthly home values.
