Being a landlord, I always answer the phone I'm a landlord / property manager too, and if someone called at 11:45 pm, my phone would be shut off and I would be asleep.

I also live in an area where it's hotly debated.1) Choose a location where the regulatory environment is not going to shut you down.

Shut the door, have something to cover the crack underneath and that becomes your dust free, dirt free zone! 

The heating system then worked overtime and didn't shut down, which created problems with one of the breakers and the mainload now came from the other breaker.

A third thought is to just put in electric baseboard heaters in each unit, and either let it work in tandem with the existing radiant heating, or just shut that off entirely.Anyone have any suggestions?

Lots of construction and military, and billion restaurants, which is where 1/2 of our owner finance buyers work it would seem :)

I have a 20 acre parcel, that is within 5 minutes of shopping, restaurants, etc. and 10 minutes to hospitals, etc.

Or like in NYC, all areas will be gentrified and taken over by big money chain restaurants that can afford the jacked up rents local landlords want.

And the location might be a different restaurant as well. 

Restaurants are very common, almost the only way to sell some mom and pop joints, smaller non-franchised motels, retail stores/business.
