If you look at the national picture in the USA prices haven't really budged by much at all, it would seem reasonable that they will but when and by how much is the million dollar question:
The availability of remote work and the retreat of the HCOL population to other areas in the US is likely causing an increase in demand elsewhere, as we have seen as a macro trend since the beginning of the pandemic. This demand will keep supplies low in LCOL areas.
I think large drops (40-50%) in most regions are likely.
