Some investment listings make you do the math. This one makes the math obvious. Two units, two garages, two private backyards (with sprinklers!), and 21 years of rental history with a combined 11 weeks of vacancy - read that again. Projected rents land between $3,600 and $3,700 a month combined, putting this at a 6.7% cap rate at list. For investors, that's already worth a call. For house-hackers, it's better: live in one side, let the other side's $1,850 cover most of your mortgage, and build equity on someone else's rent check. Both tenants vacate by August 1 - the new owner walks into a clean slate to re-lease at market, move in, or both. The 938 side has newer floors, windows, a Nest thermostat, AC, and a new water heater. The 940 side has new can lights, switches, and a 2020 water heater. A rare find with versatility, value, and strong upside in a desirable location!
