@Karolina Powell I’m a huge fan for tenants paying their own heating.

That can get a little heated depending on the bank/lender.

For example with heat, the fuel (electric, oil, natural gas, etc) all cost differently. 

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

I always look at the heating source and try to determine if it can be broken out to where the tenants pay for their own heat.

For 20 years we have dealt with space heaters (of various types) for heating the room in the cold OH winters, or just ceiling fans for cooling in the summer.

The heat lol

Gas/Heat/Hot Water is included in the rental, when completing the proposed rent form could I ask for more rent money or should I stick to what the property is originally listed for? 

Guarini Plumbers in Jersey City are great and A Degree Above Heating & Cooling are very personable. 

It does require some kind of power, but if you have A/C and heat then it works off of the one that is not currently pulling power.
