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.

Here's a photo we took (spoiler alert: plug for our college.) It's free.

There is no super cheap way to do spherical panoramas correctly, but
there are a ton of ways to do them.
Probably the cheapest way to do it is to get a panorama head for
your tripod and take a bunch of pictures of the room. I really like
the nodal ninja for doing that. It's inexpensive (compared to a lot
of the others) and it's well built:
http://www.bhphotovideo.com/c/product/838674-REG/Nodal_Ninja_N3II_PKG_NN_MKII_Starter_Package.html
To use the nodal ninja you have to carefully align the camera's lens
so that when you spin it around the camera is rotated on it's focal
point. That will be somewhere between the front of the camera and
the image sensor.
Then you just take a bunch of pictures that overlap about 30% to
50%. You probably take anywhere from 16 to 90 pictures per photo
sphere depending on how wide angle your lens is.
Then you just stitch all the images together in hugin.
There are automated versions of the tripod heads, and this is the
route I would go. They offer the ability of just set how far apart
you want your images to be taken in degrees and then simple press a
button, leave the room and wait for it to take the pictures. It
offers the cheapest and highest quality of all the panorama
techniques that I know of. A very good example of the Gigapan.
With the smaller cameras you could get the cheapest model and it's
not all that much more expensive than the Nodal Ninja.

There are also a number of specialized camera's that range from a
couple of hundred bucks to thousands. The cheapest one I know if is
the Ricoh Theta M15:
http://www.amazon.com/Ricoh-Theta-Degree-Spherical-Panorama/dp/B00OZCM71O
Many of the dedicated cameras, the Ricoh included use multiple
cameras to capture the image. In wide open spaces that it's such a
big deal, but inside buildings having multiple cameras that don't
capture images from a single focal point will cause parallax
distortion, which causes ghosting and tearing in the picture. The
ricoh only has 2 cameras so there will only be one place in the
image that will have the problem which will be in a big ring around
the whole image, top to bottom, so it might not be a bad camera for
real estate photos since you can plan where the problems will be.
When you get to higher end camera like the Panono which have 36
cameras that are further apart. Indoor pictures will become
terrible with lots and lots of strange problems. Outdoors, with
everything being much further away, the parallax distortion isn't a
huge problem and you are treated to great 108 Megapixel images.

Finally there are specialized lenses. but you'll probably have to
have a much more expensive camera and the panorama is fairly low
resolution because you are now spreading your camera's pixels around
360 degrees, but if you need to take quick high quality photos that
don't require stitching, these can do the trick, but they are
expensive. Here's an example of one of those:

Hope that helps,

Specifically, what I want to do is do a virtual tour of a house
