Shelter-in-place caused steep drops in activity across the board in what is typically the busiest selling season of the year. However, though still far below normal levels, activity has been picking up since bottoming out in late March/early April, and will presumably continue to do so with the easing of both shelter-in-place and property-showing rules.
So far, home prices have seen no declines, but a fair proportion of the sales behind April median sales prices still reflects offers accepted prior to shelter in place. Interest rates hit a new historic low in the last week of April.
