I was going to mention that you could just use your phone, but with the
amount of parallax distortion you would get indoors, because of the
close quarters, I decided to pass on it as a suggestion. Using your
phone without some fancy rig to align the lens correctly would lead to
some very strange/bad looking real estate photos.
