The roof is only 4 years old and I will be putting pretty significant repairs into the rest of the house.

trusses are a roofing component.If this is a condo, then the by-laws dictate anything related to structural issues...likely the association will need to decide what happens.Adding a bit of information on the ownership structure would be helpful. 

Another I was ARVing around $215-220k popped up post flip at $275k and they left the 30 year old patched roof, the door casing baseboards, and the ancient window AC unit in the second floor window (it looks the same outside).My guess is some of these newer flippers will end up losing out and the deals will come back (my hope at least).

Judge had no issue with the tenant's living under the same roof.

My co-worker is looking to sell his rental for what he owes on it....which is about 75% ARV....the property needs about 15-20k worth of work inclusive of a new roof.

It's had all electrical through to service replaced, new central air including duct work put in, new water heater, new roof, and literally a gut to the studs done to it.

This property is a full blown renovation that will include: gutting the the entire inside and stripping the roof.

the house is 1912, maybe check out the big ticket items --- foundation, floorboards, Hvac, windows, roof .    

just won’t be able to do roof, etc.

Landlord the structure (roof and foundation).
