Rough estimate for gut rehab of 3 flat

[Robert Obniski]

Hello all, I am currently looking to buy a 2 or 3 flat (duplex/triplex for some of you)

Ill try to give the most precise details I can and if someone could give me a ballpark figure I would greatly appreciate it.

3 units

2 - 2 bed 1 bath

1- 1 Bed 1 bath

I would need basically a complete gut and rehab which includes...

Old shingles tear off install new

New drywall

New kitchens/bath

New fixtures

New plumbing through out

New flooring

New HVAC (None pre-existing) 

New electric through out - (minus panels)

-Essentially brand new everything.

Again, ballpark figures
