What comps do you use when you can't find an ideal match?

[Connie Presley]

Hi All! I have been finding older properties in my area with very many recent sales nearby. However, there are newer communities within short distances from the older homes and I am assuming that I cannot use the sales prices for the newer homes as comps. There may be a 25 - 40 year difference in age of the homes. What comps do you use when you cannot find an ideal match?
