Why the model sees it this way
Sialim's model forecasts the typical Wahpeton home value will rise 0.2% in September 2026, from $228,273 to about $228,635. The 80% confidence range runs from $228,230 to $229,074.
Prices have been close to flat over the past three months (+0.07% per month on average), and the market is up 4.7% from a year ago.
The 30-year mortgage rate sits near 6.7% (restrictive for affordability); for-sale inventory is up 32% year over year, which adds downward pressure on prices; national unemployment is 4.1%. 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 Wahpeton were off by 0.6% on average. Smaller is better; anything under 1% is strong for monthly home values.
