I’m gonna keep the prices lower and where the action is. Here’s a rough (very rough pulled from the air but with some sense of experience and thought) attempt with peak ranges first.
550K to 700K now 450K to 600K
700K to 850K now 600K to 700K
850K to 1M now 700K to 850K
1M to 1.25M now 850K to 1M
1.25M to 1.5M now 1M to 1.2M
One quick note on these ranges. Not all properties will behave similarly within these ranges. For example, one property that was 1.5M at the peak could be 1M now while another is still 1.2M.
