The "gas on gas" stove was a mid 20th century way to modernize the heat in apartments that were originally gas lit and built to have a cast iron coal stove at one end and often a coal fireplace at the other.

The apartments have fireplace's and I guess one of the tenants didn't open up the vent when they lit a fire.

Need to search here "Rent credits" should do it, as you'll find that's not they way to go.Hope you didn't spend much on the guru book, you can use it in the fireplace tonight and get warm, I think our weather is headed your way.All in all, no to everything you have going up there.

I came across a vacant home that was advertised as a 4 bedroom, 3bath, sauna room, steam shower, barn, inground pool, pump house, screen house, 2 brick fireplaces, 2 sheds with over 5000 sq ft of acreage.

Volume allows us to obtain favorable pricing - we are in the $75-95/ sf range which includes fireplaces  granite / volume ceilings 2 car attached garages etc...Best wishes moving forward

Yes Sean, I suggest you just buy them and flip them after adding lipstick or cleaning the fireplace out and waxing the hardwood.

The last one I got that is A/C and heat is a powerful unit that provides heating or cooling for an open 500 square foot area and it was $400 at Lowe's.Another heating option I put in my own home that I also think would look snazzy and upscale in a rental, but at a low cost, is those electric fireplaces. 

@Stephanie Lella - Remove the ability to use the fireplace (brick/concrete).

No fireplace in it, either.  

Doesn't have to cost, just take things out of your own house for the fireplace mantel and some flowers or pretties on the kitchen counter.
