This is single family only I believe…so may have to check multi-family. Case-shiller YoY price movement gives same results.

Peak was Apr 2006 and bottom was May 2013 or 7.2 years (the often quoted real estate cycle). Current peak was Jul 2022 so bottom will be Jun 2029?

Case-shiller was delayed 1 year (2007) but was early on the buy side (2012). So Case-shiller may indicate to buy in Jun 2028.
