I actually already own a single-family home and don’t see myself moving into a multi-unit anytime soon—I’ve gotten a bit too used to not having neighbors above or below me  That said, I’m definitely interested in growing my investment portfolio.I work as a mortgage lender, so I’m very familiar with renovation loan products like 203k and HomeStyle.

He started making unreasonable demands like installing high-end kitchen appliances, me talking to his neighbor to not bother him, and asking me personally to clean the apartment.
