I need additional funds to finish my basement, and to start builiding a new house on the lot next door to my present three family.

If you do a search for LLCs on BP, you'll see a range of opinions - it depends on your individual situation and risk tolerance.For 2024 if you have an LLC you have to file additional paperwork with Corporate Transparency Act or face fines from the IRS.

Save up the rent money from the house hack (or start now if you already have the cash) to finish off the basement into another rental unit (if zoning allows) or additional square footage to the current property.

I think the common denominator in all of this is if you invest in a high appreciation area, or high cash flow area, and in addition, put a lot of cash down, you're pretty much "good to go".

Renovated each unit as they opened up which created additional value through increased rents.

If you add additional bedrooms, I would also consider the bedroom-to-bathroom ratio so you don't have too many roommates needing to share a bathroom.
