Don't miss this rare opportunity to own a proven-performing, high-demand duplex with loyal tenants, strong rental history, and immediate income upside - perfect for hands-off investors seeking reliable cash flow AT OVER A 6-CAP!! Both units are leased to long-term tenants: one on Section 8 ($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. Key systems and appliances are believed older but functional, 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 6.25!! Reach out today for rent roll and financials. The numbers speak for themselves!
