Be the master of your own housing destiny! Live in half of this all-brick duplex and rent the other half to greatly offset your mortgage while building your wealth in real estate at the same time. (Or, for the same money you could buy a condo in a complex with HOA rules and association payments that will rise over time with the added risk of unanticipated and expensive special assessments.) And unlike a condo, here your loan qualification uses the income from the other side--the net-lower payment amount--making it easier to qualify. Both sides are currently on month-to-month leases renting for $1395/month. Each unit of the duplex is 784 sqft with 2 beds, 1 full-bath. The room measurements are the same for both side of the duplex. Hardwood floors under carpet in living rooms. Strict 24 hr showing notice to respect tenants.Call agent for additional information.

Both units are leased to long-term tenants: one at $2,000/mo, through Dec 2026, the other at $2,150/mo through Nov 2026. The detached four-car garage adds additional value and even more income upside. Only one single-bay is included with 1436. A separate tenant rents the double-bay rented separately for $250/mo. The final single bay is currently used by the sellers but will be delivered vacant at closing for instant income potential or additional tenant perks. Both tenants want to renew at the end of their current leases, have a strong track record of on-time payments, and take excellent care of their units. Vacancy has been virtually nonexistent for years, and when past tenants have vacated, the Sellers have always found new tenants quickly, underscoring the property's appeal and strong local demand. Interiors are dated, presenting a straightforward value-add opportunity: cosmetic updates can boost rents and long-term returns. It's priced according to the cosmetic condition of the interior, but key systems and appliances are older but still functional and consitently maintained with no major issues reported. Stable income, low vacancy risk, and clear upside make this an ideal portfolio addition. **The Punchline: Turnkey income, loyal tenants, and untapped upside - all in one package, at a Cap Rate of over just under 7!!
