I'm looking at data for some second home markets - and will track those markets to see if there is an impact from the lending changes.
This graph is for South Lake Tahoe since 2004 through August 2021, and shows inventory (blue), and the year-over-year (YoY) change in the median price (12 month average).
Note: The median price is distorted by the mix, but this is the available data.
Following the housing bubble, prices declined for several years in South Lake Tahoe, with the median price falling about 50% from the bubble peak.
Currently inventory is still very low, but solidly above the record low set five months ago, and prices are up sharply YoY. This will be interesting to watch.
