Jacksonville, FL cost per square foot to rehab (wholesale Calc)

[William J Hamm]

Has anyone found the cost per square foot to rehab in Jacksonville, FL? I'm looking for $ figure to use when estimating rehab costs for wholesale deals.  For example, is $15 per square foot times the square footage of a property a good number for a cosmetic rehab cost?  What's a good per square foot cost for a light, medium or full rehab?  If anyone has found some good numbers, please add them to this forum.  Thanks
