About this property

INVESTORS & HOUSE HACKERS—THIS ONE IS READY TO GO! Welcome to 4028 S Spring Ave, a nicely updated South City duplex offering an excellent combination of current rental income, an immediately usable second unit, and several important improvements already completed. Whether you're looking to add a straightforward rental to your portfolio or live in one unit while generating income from the other, this property offers plenty of flexibility. The 1st-floor unit is currently occupied at $850/month, plus an additional $50/month toward water, sewer and trash, providing $900/month in current gross income. The 2nd-floor unit is vacant, giving a new owner the opportunity to move in, place a new tenant, or establish their own lease terms. The previous tenant also paid $850/month plus the $50 monthly utility contribution. Seller will provide the occupancy permit for the vacant unit. Recent improvements include a new sewer lateral inside the building, updated kitchens, new LVP flooring in the kitchens and bathrooms, and two new electrical panels. These updates take some of the big-ticket concerns off the table and make this duplex an attractive option for an investor looking for a property that is ready to put to work. For the investor, the existing tenant provides day-one rental income, while the vacant unit creates an opportunity to establish a new lease and increase overall gross income. For the owner occupant, live in one unit and let the other unit help offset your housing expenses—a classic South City house-hacking opportunity.The building offers the charm and character buyers expect from a South City duplex while incorporating practical updates that today's tenants and owners appreciate. With one unit already producing income and the other ready for its next occupant, 4028 S Spring is a duplex worth adding to your tour list!
