What should this rehab cost?

[Mayer M.]

Hey guys, Looking for any advice you can provide on your opinion of what an upcoming rehab I have should cost. The property is in Philadelphia, it’s a triplex with approximately 3200sf gross sf (including exterior walls). Basement and first 1st floor will be a 3/3 bilevel, 2nd floor 2/1, 3rd floor 2/1. This is a gut rehab. Any idea what something like this should run? It’s also worth mentioning that we will be going with ductless mini splits for HVAC, will be adding one small balcony on the 2nd and 3rd floor, will need a sprinkler system, and the basement will have to be dugout 1-2 feet and are unsure yet if underpinning is needed. Any advice would be greatly appreciated! Thanks
