Why the model sees it this way
Sialim's model forecasts the typical Sebastian home value will fall 0.3% in July 2026, from $365,307 to about $364,091. The 80% confidence range runs from $363,883 to $364,701.
Prices have been slipping, down an average of 0.22% per month over the past three months, and the market is down 2.8% from a year ago.
The 30-year mortgage rate sits near 6.5% (elevated for affordability); for-sale inventory is down 16% year over year, which supports 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 Sebastian were off by 1.2% on average. Smaller is better; anything under 1% is strong for monthly home values.
