Anyone have experience converting the heating in a house from oil to gas and separating all of the units with separate meters.

I provided a letter of intent to occupy, as well as the current lease agreement for that property valid through Oct '16.

Yes, depending on your local ordinances you can expect inspections for structure, electrical, plumbing, roof, gas, etc.

She said she would help with whatever I needed and immediately got a contractor out there to turn the gas off and unhook the gas line from the heater (one of the things the owner failed to mention she wanted until the last minute).

If you execute one of these yourself, and get it notarized, is it valid without a title search, insurance, etc?

Google "goodwill letter" and "debt validation letter" for ways to clean it up

So gouging is a valid concern. 

@John Paul many people on BP would tell you to invest in a less expensive market, and there is some validity to that.

The issue it there are 2 separate gas and electrical meters for the 2 apartments. 

Separate water, gas, electric.
