Since then I've bought two apartment complexes and will be building additional units on them using knowledge  and processes learned for Jerome and his colleagues.

Greetings and stay focused and united. 

What if you have an apartment complex with 20 units?

Why 4 units in 4 years?

Give her 30 days notice now, keep her security deposit, and send her a additional bill for damages to the unit in lieu of taking her to court for the damages.  

It may be helpful:I can give you some general info on insuring the property:Here are some things to look for from an Insurance prospective:1.Any in-ground tanks (active or inactive)2.Any Knob & Tube or Aluminum Wiring3.If built before 1978, does the building have Lead Safe certifications4.Any wood stoves or secondary heating units.

A water heater replacement is $1500, AC Unit $8,00011.

If you're planning on living in the unit during the winter and renting it out over the summer, you could have the best of both worlds.

Not sure what market you are in, but I would talk to some lenders about FHA options on a 2-4 unit property.

Live in one side and renovate that side, then after the lease for the other unit is up move into that one and renovate it.
