Outside of heating issues, I don’t expect much.

Running water and Heat.

He wants us to install permanent heating in all the bedrooms which will cost alot of money that we don’t have.   

It's all the agents that leave your lights and heat/a.c. on and doors wide open.  

I recently had a buyers agent tell me (at my house) my heat pump was 20 years old and was at the end of its life and needs replacing . 

I would guess the heat source listed is probably the gas heat where gas is included in the rent.

You don’t want to have to repair their dishwasher, heat system etc in when you’re putting in a new one, anyway.

This formula is already in place for water, but here's the issue with gas -- both units use gas heat, however only one unit has a gas range/stove (the other unit has electric). 

A 24x24 shell with no heat or insulation and 15 amp power can rent for $600 a month.

This will allow you to run specific underwriting and projection tools to better assess each option.Remember, owning a property with a pool comes with added expenses, such as heating, emergency and routine maintenance, and higher insurance costs.
