By some measures, home prices are rising at a faster pace than they ever have – an incredible feat considering the market is rising from an already elevated level. The supply of for-sale homes, already extremely tight, has only become more constrained in recent months, and historically low mortgage rates continue to encourage many buyers to enter the market. This heightened competition for the few homes on the market has placed consistent, firm pressure on home prices for months now, and there are few signs that this will relent any time soon. While the path of the overall economy is likely to be most directly dictated by coronavirus-related and political developments in the coming months, recent trends suggest that the housing market – which has basically withstood every pandemic-related challenge to this point – will continue its strong momentum in the months to come.

Annual growth in September as reported by Case-Shiller is expected to accelerate in all three main indices. S&P Dow Jones Indices is expected to release data for the September S&P CoreLogic Case-Shiller Indices on Tuesday, November 24.
