Tips on how you determine market value of a house??

[Account Closed]

Hi,

I'm a new investor and I'm trying to find the best ways to determine market values of homes in an area I think I may send mailers to. I'm noticing there are so many houses for sale and the prices are very inconsistent. I'm trying to analyse it by price per square foot, but I cant find any consistencies. In this market there are more foreclosures then standard sales. I can tell there is a lot of investment activity.

Any tips on how you determine market value of a house? Do you look at the price per square foot, or sale price? Is there a rule of thumb here??

Thank you!!
