Cost per Square Foot Estimate

[Maxwell Hunter]

Question for my flippers/rehab specialist in Atlanta GA and the surrounding metro.  On a recent podcast (not BP Podcast), an investor was explaining that he estimates rehab costs based on an average price per square foot.

Does anyone in the area use this method to calculate rehab costs?  If so, what are you seeing typically?

Also, I would imagine it varies greatly depending on the type of flip (cosmetic versus extensive).  So are you using two or three different averages depending on the type of rehab?
