Investment Opportunity – Value-Add Fourplex with Future Upside Potential
Rare opportunity to acquire a charming four-unit income property featuring four detached cottage-style residences situated on a cozy, park-like lot. The unique layout provides tenants with a greater sense of privacy and independence than traditional apartment living, while enjoying mature trees, abundant green space, and ample on-site parking.
This value-add property offers investors the potential to increase rental income through unit improvements and may present opportunities for additional development, including possible ADUs or expansion of the existing unit count, subject to buyer verification and approval from local authorities.
The property has benefited from upgraded electrical infrastructure, providing added value and supporting future improvements or expansion possibilities. Investors will appreciate the combination of existing income, utility upgrades, and long-term upside potential.
Ideally located near parks, the library, schools, shopping, dining, and public transportation, the property offers strong tenant appeal and convenient access to major commuter routes.
