Where does the stove and fridge go?

I have an owner I manage for right now who was unable to sell his property in the same scenario that you described, except his second unit is a converted attic, I neither FHA or VA would approve lending on the structure.All that said, what defines a separate living unit is a working stove.

Any wood stoves or secondary heating units.

The current stoves are gas and are 20inch units with a pilot light that stays on all the time (meaning I have to pay)My question is if I should switch to electric stove?

Having the stove, water heater, and dryer all gas encourages them to keep the gas on.

For safety/code reasons these separate "units" cant have a stove and must of course meet building codes for adequate ceiling height, windows, etc, but it can be a great first step in a market where MF is so expensive. 

Does anybody have a recommendation on a 20" stove/range?

Even if this example I fixed up the stove since it was broken it was a repair and not a capital expense.
