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:

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:

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:

you can get a hat with a camera on it to do that. Well, I doubt I can
afford that hat so how could I do something similar with a camera?
Specifically, what I want to do is do a virtual tour of a house and of
it's property. Could someone help me?
