Fully gut-renovated multi-family with permitted 2021 renovation — this property underwent a comprehensive top-to-bottom renovation completed under full permit in 2021, including brand-new boilers, all-new plumbing, and all-new electrical systems throughout. Every kitchen was fully renovated with new cabinetry and new appliances. The property has been professionally managed and well-maintained since renovation. Currently tenant-occupied at will; the first-floor unit will be delivered vacant at closing — ideal for an owner-occupant or investor seeking immediate income with upside. Don't miss this turnkey opportunity in a renovated, low-maintenance asset.
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 MLS and other third-party data may be inaccurate or out of date.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.
