HighLights
- Year built 1900 building with 3 floors of living space and 4 bedrooms
- Partially finished walk‑out basement with tenants in place through August 2026
- Approved plans included to develop into a 4‑floor two‑family
- Plans call for two duplex‑style units with generous square footage
- Opportunity to extend living area by maximizing by‑right FAR of 2.0
Overview
The package also references a site-specific development path that includes maximizing the by-right FAR of 2.0, with the plans designed to support generous unit layouts. With approved documents included, buyers have a defined basis for moving forward with the proposed conversion.
For investors and developers, this offering combines present-day operating income from in-place tenancy with a clear redevelopment roadmap tied to approved plans and by-right development parameters. Buyers can evaluate whether to pursue the planned duplex configuration as a long-term hold consistent with the existing tenants’ schedule, or to align the completed residences with their own end-market goals, including potential condominium-style delivery as contemplated by the included plans.
