About this home

Rarely does a trophy mixed-use asset of this caliber surface in Long Island’s most coveted coastal market - Long Beach. Presenting a fully gut-renovated 10-unit free market residential building paired with 4 ground-floor commercial storefronts and a dedicated laundry room for tenants— a combined 14 income-producing units in the heart of Long Beach, NY. The Property: Renovated in 2025 and finished with spa-caliber finishes throughout, this is not a cosmetic renovation — it is a complete reimagining. Residential units showcase high-end, turnkey interiors that command top-of-market rents, while the four street-level commercial spaces deliver diversified income and powerful pedestrian foot traffic. The Location is Irreplaceable: Situated just 3 blocks from the Atlantic Ocean, residents enjoy world-class beachfront lifestyle year-round. The building sits directly across from the Long Beach LIRR commuter rail station, placing Manhattan within easy reach — a combination of coastal living and transit convenience that drives perpetual, recession-resistant demand. Long Beach’s red-hot rental market, vibrant restaurant and retail scene, and continued influx of city-to-suburb migration make this one of the strongest fundamentals stories on all of Long Island. Free market status means no rent stabilization caps — full upside as the market grows. With 10 residential apartments and 4 commercial units, this asset delivers immediate cash flow across two income streams with long-term appreciation baked in. A fully renovated building means minimal near-term capital expenditure and a truly turnkey ownership experience from day one. Opportunities like this — gut renovated, free market, mixed-use, steps from the beach, across from transit — are extraordinarily scarce on Long Island. This is the kind of asset institutional investors and family offices compete fiercely for, and rarely find. Buy it. Hold it. Pass it down for generations.
