My brother is a restaurant owner. He bought the building one of his places was in, along with several other businesses. Initially it was a struggle to keep the mortgage payments going, but over time the other shops faded out and he replaced them with higher rental rate tenants. His restaurant there eventually died a slow lingering death, but even then he just got in a new tenant with higher margins that could afford more than the rent he was paying himself anyway. In any case, he's now got a lot of equity and a steady stream of income from the building.

His partner in his other restaurant owns the building they're in, and also owns 3 of other 5 businesses in the building. Nice setup if you can get it.
