Estimating repair cost

[Patrick Philip]

I just started a new wholesaling campaign. I have been receiving many calls. Do I have to physically go look at every house? I plan on expanding to the point where this would be impossible in the near future within the next few years.

How do I estimate repair cost without going to see the house? Do I use a certain dollar per square foot? If the home owner says it's in "good condition," what do I put for repair cost?
