Attention investors and "house hackers": 513 South 13th Street represents a rare chance to own a high-yield, dual-structure asset in Philadelphia’s coveted Washington Square West. This RM1-zoned lot features two fully independent buildings: a 4BR/2BA front house and a detached 1BR/1BA rear cottage. Both homes are loaded with the "original character" that drives premium rental rates in Center City, including original hardwood floors, multiple fireplaces, and exposed brick walls throughout. The layout is a dream for modern portfolio strategy. The main house features an open-concept first floor and three levels of living space topped by a roof deck. The rear cottage is a perfect separate rental unit or a high-end guest suite. With RM1 zoning already in place, the potential for long-term appreciation and consistent cash flow is exceptional. Continue the current owners' path of success with a dual-rental strategy, or live in the cottage while the 4-bedroom main house pays your entire mortgage. Properties with two separate dwellings on a single deed are rarely available in this zip code—seize this turnkey opportunity in the heart of the city.
