Investment Insights
Based on property information with market context.
This one-of-a-kind mixed-use property totals 4,082 square feet and was previously used as a club/fraternal association. The main level is designed as a spacious open area for commercial use. The second floor includes multiple rooms and bathrooms, and the third floor concept calls for a loft-style apartment layout. The building is currently under construction, with an overall idea to combine storefront/office space on the first floor with residential apartments on the upper levels.
The property is located in North Bethlehem at 431 W Union Boulevard. Set on an approximately 0.286-acre lot, it includes a rear parking lot along with a detached storage building and a garage that has water and electric. Additional outdoor space is provided by a large side lot, giving the site flexibility for future improvements.
For tenants, this configuration supports a combined live-and-work approach, with dedicated commercial space below and multiple apartment units above. For buyers and developers, the existing building footprint and lot features create a straightforward path to complete the conversion as envisioned, with parking and service structures already in place on site. Arrange a showing to review the current construction status and discuss how the plan can be tailored to your needs.
