I am about to rip a roof off in EAV  (Atlanta, Georgia) and might need some engineering and architecture help. 

For example, a roof costs the same for a building that rents for $900 vs one that rents for $1400.

The garage roof has reached the end of its useful life and needs to be stripped off and replaced by a licensed roofing contractor. 10.

Too much squeeze for too little juice, and you'd be very close to getting burned on the deal should you have an unforeseen major expense such as a nightmare tenant you'd have to evict and/or capex such as replacing the AC or roof. 

If the electrical panel is substandard (dangerous) and they are the one who hard wired an extension cord in the attic while cutting through a major purlin holding up the roof, and the garage door doesn't open due to damage (when they hit it with the car?)

Are the roofs, lawns, exteriors all well maintained?

But after all, he made a great decision and it was amazingly profitable.Numbers:80k Purchase – cash 35k – Reno Roof, siding, paint inside and outKitchen cabinets and countertop resurfacedPlank floor New tile in bathroomRepair electric and plumbingHome staging 1% of sale price6 month project 165k sale price less 6k closing costs44k Profit Regrettably, this will probably be the most profitable flip I am involved with for the foreseeable future.

I made an offer on a foreclosed property that needed everything redone (roof, hvac, windows, kitchen remodel, paint) and they came down a whooping $4,000. 

The house probably needs a new roof and maybe 1-2 other things but it's mainly cosmetic updates.

I would be purchasing one unit out of four in the building, which was constructed in 1975 and needs exterior repairs including to the roof, carport, trees and paint.
