Basement Remodel Cost Estimate Based on Square Footage??

[Branden Wilson]

Hi everyone! I'm in Maryland and trying to refine the spreadsheet I use for estimating rehab costs. Any input on a number you use to create a high level estimate to finish a basement based on square footage? (ball park that would include framing/drywall, electrical/recessed lights, flooring, etc.) Again, just trying to get a ball park rehab number.

For example:

Cost for a completely unfinished basement (older home, stone foundation, worse case scenario)  = Square Footage * $XX = Estimated Cost

Cost for a partially finished basement or one that has been finished but needs rehabbed = Square Footage * XX = Estimated Cost

Thank you!
