If rent can offset the cost of renting furniture (or you can use some of yours) it might work. 

LOTS of reasons:- Stains the walls and ceilings when people smoke inside- Gets inside the carpeting and makes the house smell bad -- really gets into curtains and furniture too- Can make burn holes in carpets- People put them on the counter tops and they wind up causing stains/burn marks- People flush them down the toilet and it causes clogs- Butts litter the ground around the house because smokers seem to think littering butts is okay (when did just throwing a used butt out your car window or anywhere outside on the ground become "okay"???)

Decor and furniture add up.

Assembly and dismantling: You will help with assembly or dismantling of light furniture and fixtures.

Can you recommend companies to get furniture and commercial bedding that work well for you?

Absolutely NEVER allowed on any furniture. 

The buyers did request a $5,000 closing credit to put towards new furniture that I agreed to, but probably would not do again.

Just need to take into calculations the furniture cost and some slightly lower rents for the first month or two while your listing gains traction. 

If you have the energy then the Phoenix valley is a great for flipping homes or short term rentals.For flipping homes you will need to find homes that are below market and/or are in need of some cosmetic renovations and can be staged with the right furniture.

would you have to store the furniture otherwise?
