I provided a furnished room and amenities geared to that group and advertised on the bulletin board at the University of Washington School of Medicine.

What I feel you're missing with the payment calculator is they use it as a means of advertising.

I have found a house that is in foreclosure that is being advertised for rent.

Possibly advertise on craigs as a job with the perk of living rent-free? 

They don't advertise.

Personally, I would simply advertise it as "three-bedroom unit but one bedroom does not have closet" or "two-bedroom unit with an office space that could be used as a bedroom."

(Because applicant’s credit report would be accessible to you through the site, I would ask your agent to open his own account there, advertise your property, and deal with everything from A-Z - for liability purposes - like he would anywhere else.

I guess it's not too common if a vendor was advertising it (at least not Home Depot common).

I know of some furniture companies doing staging for free, as it can help to advertise their products while you are trying to sell the house.

You have to build up a buyers list, such as by advertising or going to your local REIA.
