Where can I learn about non-traditional homes?

And have any jellies ever lived in one? I’m curious about tiny houses, boats/ houseboats, trailers, communal living, and anything else that is not a typical house or a rental. After googling and reading on the internet, what is the next step to learn about these?

I’m in my late 20s and renting a small apartment with friends. For many people this age, the next step is to save for a down payment and buy a house with a 30-year mortgage. Tuition and home price are increasing relative to income, and people in my generation are struggling with student loans. It just seems like a recipe to be in debt and chained to a desk your whole life.

I will probably try to buy a small, older home in an area with a lower cost of living. But just for funsies, what does the collective know about this stuff?
