The initial thought is you are probably charging too much if no one is interested, or your photos or description are bad.Four beds and only one bath probably reduces demand as well, that’s potentially a lot of people sharing one toilet.And it is winter - I’m in Buffalo, I hate listing rentals this time of year.
