Comparable Sales - Only old properties sold in the neighborhood

[Sam Pant]

Dear BP,

I had a realtor run CMA on one of the SFH deals I am looking at. She ran the analysis and came up with an average price/sf. There are four properties included in the analysis. However, all these four properties sold are older houses (not remodeled). Is this CMA an accurate measure of the ARV of subject property?

Many Thanks!

Sam
