I never subscribe to using a nom de plume. 

And a 5 gallon bucket next to the toilet plume full also. 

You have to account for time to manage the property or pay for a property management co and I recommend getting a home warranty company to handle appliance and pluming issues.

Super easy to do (I did this multiple times when I rented homes in my 20s).Pluming issues (toilets, sinks, etc) - usually landlord, but it depends.

I ran electrical and pluming in mine and dont anticipate any huge expenses in the next 5 years.  

I'm sure I will have a large amount of equity in the property at purchase because I can get it so low and it would only need a new condenser , PVC pluming to replace the old cast iron stack , simple roof work, and a new breaker panel. 

This sounds like just a pluming fix, little demo/mold work, and some finish work, doesn't sound very expensive in the grand scheme of things.

This gave me an eye of what I thought would need to be done and what it would run me for future properties.I still get inspections to make sure I'm not missing something major like bad wiring, major pluming, or foundation issues, etc. 

My point was they have been trying to do away with the pluming license lately. 

@Justin Woodworth, the owner may be paying for utilities because they aren't separated. to do so would mean re-wiring and re-pluming the entire building and potentially installing 14 separate furnaces and water heaters.
