General Contractor Massachusetts - Cost

[Chan K.]

Hi BPers,

I have been evaluating one of the brrr properties. I want to get a baseline norm of some of the cost. I would like to share your experience in Massachusetts rehab. This is a multifamily asset. 

1. How much does it usually cost to have a General Contractor come down and itemize each cost (roof, siding, plumbing, floor, paint, electrical, .... etc)? I would envision he generates a standard formal report afterward that I can bring into the bank office. 

2. For a 3-plex 2999 sq, would it be safe to approximate 10k-15k roof with labor+materials?

3. For a 3-plex 2999 sq and colonial, would it be safe to approximate 20k plumbing with labor+materials (new plumbing throughout)?

4. For a 3-plex 2999 sq and colonial, how much does it cost to update minor electrical items?

5. For a 3-plex 2999 sq and colonial, how much does it cost to update heating system?

Thanks,

-Chan-
