(two knobs... one to choose oven or broiler and the other to set temperature) I was charged $50 for the service visit and I sent it to the property manager to have the tenant pay.The next day the tenant calls and says the oven burned the top of their food and obviously the oven does not work correctly.

It monitors temperature, humidity, and electricity.

You could also have a separate agreement outlining house rules...I havent done this but it's something i'm considering.Here are a few issues that have come up while I've house hacked:- Tenants disagreeing about how clean the common areas should be, WHO is cleaning, and whether it's worth having a cleaning service (monthly)- the house's temperature- Some tenants leaving things out in the common areas and other tenants getting annoyed at it.Every situation is going to be different, but if you've ever lived with roommates...it's similar to that, except you're not paying rent! 

Being in Texas with a lot of drill rod, if you have a welding friend with a high lift, I would look to do Canopy parking. 

I had a septic system on a multi family rental in New York State.. it freezes during extreme temperatures and sometimes backs up.

We also have a very low cost of living (probably because the weather sucks and nobody wants to live here) but if you can tolerate 45 degree shifts in temperature in a 24 hour period you'll love it here!

I'm curious to know what's the right thing to do in this situation...I've explained to the Bottom tenant he has the luxury of controlling the temperature of the house.

Quote from @Dustin Sanders: @Quinn Olivarez I have the 3 markets I'm in listed below:- Pensacola, FL- St Petersburg, FL (technically Gulfport, FL)- Helen, GA I would think Helen GA will pick up when the temperature warms up.

Fall & Spring HVAC Service Target Date: April and October This service can aid in early detection of costly problems and save the cost of expensive, emergency service.A/C Service Includes: Check condenser coil, adjust operating pressures, monitor safety controls and starter capabilities, clean or replace filter, adjust blower components, calibrate thermostat, measure for proper temperature differences, clean condensate drain, tighten electrical connections, measure voltage and amperage on motors, lubricate moving parts.

With the utilities on, the building temperature stays relatively the same.
