NEW PRICE—compelling Blackstone two-family investment opportunity with income potential and flexible owner-occupant options. Potential gross rental income of up to approximately $5,400 per month when both residential units and all six garages are leased; buyer and buyer’s agent to verify rents and projections. One unit currently rents for approximately $2,100/month, and two garages generate an additional $350/month. The second 2-bedroom, 1-bath unit is move-in ready for occupancy or rental. Both units offer updated kitchens, renovated baths, granite countertops, and fresh paint, with separate utilities for easier management. Additional features include six garages, five off-street parking spaces, a basement bonus room, and a detached 12' x 18' building with electricity offering added flexibility for storage, a workshop, or other permitted uses. Convenient to shopping, amenities, and major routes. Uses and income potential are subject to buyer due diligence and local requirements.
Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
