Cost of repairs; how do you do it?

[Brant Vaught]

I tried to find a thread but didn't see one. My question is for all of you experienced investors. How do you estimate cost of repairs when you go look at a potential fix & flip? Do you have a google doc spreadsheet that you can plug numbers into, or do you have a rough estimation sheet such as house is A B or C rehab, and A is going to cost $X per sq ft to fix correctly? I am assuming you don't have a contractor come do a walk through with you. Or do you just take an insane amount of pictures and go over them with the contractor? If you use a list, is it something that you have gone to the hardware store and priced everything yourself, or would a good contractor know? Lots of questions haha. 

Thank you all in advance!

I'm not sure how you could have missed ALL the information available on this topic.  It's literally everywhere on BP.  The best place to start is with The Book on Estimating Rehab Costs...
