I looked it up, real property is the stuff you own that is not movable; you can't move a piece of land, it's just gonna be where it is. It's also property that is affected by the environment around it in a way that other property isn't. If your neighbor uses a cheap phone, your phone does not depreciate in value as a result.
The opposite of real property isn't fake property, it's personal property. That covers your stuff and also things that aren't physical but you own anyway, like intellectual property.
There's also bads that go along with goods
