However the numbers are great & the house had new roof, electric, kitchen.

What I've found is a 36,000 sf mixed-use property, all-brick, built 1914. 7 huge garage bays in 2 separate wings of the building, a storefront that needs serious work, one finished 2-bedroom apartment, and 2 upper floors that are completely gutted and ready to build out. 6 electric meters in the photo, likely shared oil heat for the whole place, all new windows, new roof, new sprinklers, masonry looks OK from pics and street view. 

The problem is not having a foundation, septic, electricity or well to hook it up to.

@Allen Lopez Likely yes.You'll probably need multiple permits, because you'll probably be running electric into it (garage opener and lights).I would guess a construction and electrical at minimum.As other have said, get with the city, they'll let you know what you need

On the other floor, the current owner left an unfinished extra bathroom, walls to finish off in the laundry room, unfinished kitchen counters, a temp electric pole that needs to be updated to something permanent, and an ac unit that needs to be replaced.

The following week, they needed to shut the power to fix the siding behind the electric meters.

The building needs pretty much everything, including foundation repair, new roof, structural repair, new plumbing, heating, electrical, etc.

Asking price is 430k (high-side and been on the market for over 150 days)Monthly expenses are $360-400 (tenants pay cooking gas and electric)Monthly income is $4000.

I would like to hire out each subcontracter by myself ( one company for flooring, one for electrical, one for plumbing, one to do kitchen etc) i guess my first step is to make sure the roof is okay.  

I buy stuff that needs full rehabs at deep discounts, and do full rehabs, New furnace, water heater, electrical panel if needed, flooring, kitchens, roof, windows, ect as needed and force the value up, so I tend to buy between $20-50K so $10-30K rehab and get an ARV between $80-120K with rents at unusually .8-1% of ARV or 2%+of my all in cost, this spring boards you forward, doing BRRR without needing more cash, because you can get all your money back out, I try to keep my equity high and debt low with the prospect of economic changes over the terms of a loan, lots can happen in 15+ years. let me know if i can help, I have 24 locations, 27 doors Im in West Bend and have stuff all over WI.
