Please pay special attention to plumbing and electrical.Enough threads on BP on pros and cons of turnkey buying.

However, I ended up getting a property that needed a new roof, water and sewer main, new electrical, and some plumbing work.

Short-term not allowed by city.Condition: Built in 1930, All units are updated, newer roof, new windows, new foundations, new sewer, new electric/plumbing.

Be careful with the foundations, the soil is sandier so it's common for shifting to occur which will affect the plumbing. 

Cost of plumbing, drywall, electrical, etc. is the same.

So, ballpark figures are from electrical, plumbing, flooring, drywall, and ventilation. 

My guess is the whole building has settled, so lots of slanted floors, sticky doors, walls out of plumb, which makes it difficult to hang cainets etc.

When were the Electrical, Plumbing, and Heating last updated3.

It was down to studs when I bought it and I did almost everything except for plumbing and electrical myself.

One major caveat is the real possibility of being put out of your own home if you ever get into a domestic issue with a tenant - I know people who have ended up having to rent a hotel room while they got something worked through the court and their tenant lived in their home, because once you rent to them it becomes "their home".
