People with second homes, vacation properties(think cabin), and time shares will do this with whatever they aren’t using. Often, it comes with taking care of pet fish, reptiles, birds, or even dogs/cats that don’t like the other property, are incontinet, or aren’t allowed there for whatever reason.

Speculators/Investors will avoid this however they can. They deserve all the squatters, and squatters deserve homes. Very very few people choose squatting over more conventional options; Even they aren’t the villains of this story.
