How to accurately gauge rehab costs

[Richard Frazier]

As a beginner wholesaler one of the key fundamentals of my role is estimating rehab costs. Being only vaguely familiar with the rehabbing business I could end up giving hit or miss estimates and this is something I'm attempting to avoid. When gauging on-the-fly rehab costs I see a couple of different methods (there are even multiple just here on BP). I may end up reaching out to contractors I've done business with but this not some I want to lean on and do for each job. I'm in the Flint area but will be branching out slightly further than where I'm based so I'm wondering if anybody on BP in Genesee County or Mid-Michigan is experienced at hitting rehab costs right on target with their own method that would be accurate for what contractors in this area are asking. Any tips would help...
