How much of their own money do they spend on marketing, licensing, education, gas, etc?

@Shane Brown I'm pretty sure that place has been on the market longer than that, I think it was for sale when I was looking around last fall, they probably re-listed it - 90k isn't an unreasonble price, that means you have to offer less than 90k and have room to move up.At least go look at it, look at neighboring properties, look at how the tenants live, verify heat type like Amy said, just completely avoid if it's electric heat (it looks like it's Rinnais though) unless you want to spend a few thousand on gas installs.

I would look at turning it into a gas fire place with crush glass.  

Things like who pays for water, electric, gas and etc are properly accounted for in writing in the lease.

The gas furnace and AC are very old and defunct.

I also pay less for electric, water, sewer, gas and supplies. 

The gas furnace and AC are very old and defunct.

We are trying to negotiate a lower purchase price (I'm hoping for $275k) and found out tenants pay for gas and electricity.

Almost blew up when the gas was turned on due to an uncapped pipe but that is a story for another day.
