Expanding this out to all of the 55313 zip code:
125 single family homes sold year-to-date
146 single family homes for sale
==> again, approx. 7 month supply of homes for sale.
Of perhaps more interest to you for Buffalo:
- listings sold are up 9% from last year at this time
- inventory of homes for sale is down 39%
- new listings are down 15%
- avg sale price is down 26% from 2008 which is attributable to what Aaron talked about below, that is the effect of the lender mediated and foreclosure sales.
Someone may have the data point you are looking for but my belief is that this data point is far too generalized to be of much use.
