This is in RI so letting the heat out is not just a big cost but a risk.

The handyman then quoted me $3500 for heat treatment for the bedbugs. 

Is it worth it to put in central heat and air?

Do you have central boiler for water and heat or individual units?

So, anyone who tells you to worry about the heat in AZ doesn't get it. 

The first house that I bought was 17 years old, 3 br, 1.5 bath, brick ranch house with hardwood floors, Andersen windows, ceramic tile baths, gas heat and a brand new roof. 

@Mark Ross  don't include heat in rent on an ongoing basis. 

The garage was built to work on trucks having 14' ceilings and 2 bay doors heating cooling about 700 sqft.

hi all i am a new landlord and got my first rental property. tenants moved in in September and October. the first month was fine but when December hit it got extremely cold and the heating is electric. due to poor insulation in the home that we did not know about the heat has to be turned very high up to keep the home warm, however since everything is electric it is causing the electric bill to be $800. the utilities are the tenants responsibility. however because of this one of the tenants has been extremely non compliant with paying rent.

New floors, appliances, heating/cooling, etc.
