Why the model sees it this way

Prices have been close to flat over the past three months (+0.10% per month on average), and the market is up 3.7% from a year ago.
The 30-year mortgage rate sits near 6.5% (elevated for affordability); for-sale inventory is up 15% year over year, which adds downward pressure on prices; national unemployment is 4.2%. 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 Great Falls were off by 0.3% on average. Smaller is better; anything under 1% is strong for monthly home values.
