Perhaps but even if that is the case, the general consensus appears to be that home purchase prices increased ~17 - 19% over the last year so right in line with the estimate by this site. If anything it would drag the estimate upwards.
OTOH, low interest rates have balanced that out, and let people who already have mortgages lower their monthly payment drastically. I wonder if monthly payment is perhaps a better metric than purchase price? At least for me, that's what actually determined how much home I'd be able to buy.
