Prices have been close to flat over the past three months (+0.02% per month on average), and the market is down 0.3% from a year ago.
The 30-year mortgage rate sits near 6.5% (elevated for affordability); for-sale inventory is about even with a year ago (+1%); national unemployment is 4.2%. 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 Hilton Head Island were off by 0.4% on average. Smaller is better; anything under 1% is strong for monthly home values.
