repairs for wholesale deal

by Aaron
(Stafford)

I am looking to make an offer on a distressed property in my area. The owner has agreed to show me around the property, but I have zero expertise in making repair estimates. I have been trying to link up with a local contractor or rehabber to accompany me to the property, but I haven't had much luck yet. I want to make an offer as soon as I can, but I don't want to miscalculate the cost of repairs. Any suggestions?
