And of course, the hard numbers from plumber and the gas company to install required piping and safety systems including what gas company will charge you to supply your property. 

Won't mean jack, if your not patient.

@Jessica ZolotorofeWhile I appreciate your time and effort here as I am not sure if I can be this patient with a total stranger, I agree we should stop this discussion here as things just seem so different...I am very familiar with what you mean by % of interest, as opposed to the whole building...

Took used AA batteries...out of safety devices. 

It's a whole house rewire including new service drop by the power company - - very expensive - - but mandatory for safety as the cloth insulation has rotted away.Plaster was applied over a lath base and you strip the walls & ceilings down to the studs to replace with today's wallboard.Bet you had no idea of what you've gotten into - - sorry to be the bearer of bad tidings.

Can anyone recommend a good, PATIENT commercial real estate agent in Indianapolis, please?

Be patient and persistent.  

I would try to make present it as a safety inspection - checking the smoke alarms, cleaning the fireplace or dryer ducts, etc.

Under HIPAA laws you arent even allowed to know if a tenant is smoking medical marijuana (think doctor-patient confidentiality).
