5 tips for buying multifamily properties
- House hacking is a superpower: live in one unit and rent the others. You can use an FHA loan (3.5% down) for up to 4 units.
- Always request the seller's actual T12 (Trailing 12 months) financials, don't rely on 'pro forma' numbers.
- Check if utility meters are split. If they aren't, the landlord usually pays, which eats into cash flow.
- Don't forget CapEx. Multifamily means more HVACs, water heaters, and appliances to replace.
- Review the existing leases carefully during due diligence.
