Estimating ARV... Factor out distressed sales?

[Asher Anthes]

When estimating the approximate retail value that I should get when the house is fully fixed up, isn't it necessary to not use the "distressed sales" in my comps? Obviously, in today's market there are a good many foreclosures that will bring down the price. Should I try to weed these out and only use comps that were sold in similar condition to the potential house when it will be all fixed up?

I want to get my estimated ARV as close as possible on my first flip, it seems like that is probably one of the most important parts of making a profitable deal, correct?
