Why the model sees it this way

Sialim's model forecasts the typical Kapaa home value will rise 0.4% in September 2026, from $1,018,439 to about $1,022,190. The 80% confidence range runs from $1,021,211 to $1,023,905.

Prices rose an average of 0.26% per month over the past three months, and the market is up 2.0% 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 (+1%); 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 Kapaa were off by 0.2% on average. Smaller is better; anything under 1% is strong for monthly home values.
