Seaport South Condominium at 130 Water Street is a full-service condominium in the Financial District, on Water Street between Wall and Pine, steps from the South Street Seaport and the East River Esplanade. Built around 1955 as an office building and converted to residential condominium ownership in 1983, it is one of Lower Manhattan's early office-to-residential conversions — part of the downtown condominium boom that turned the district's commercial fabric into a residential neighborhood.
The appeal is location and liberal condo rules. The building sits near the 2/3, J/Z, 4/5, and R trains and the ferry terminals, in a corner of Lower Manhattan that pairs the Seaport's waterfront with the Financial District's transit and services. It is a full-service, pet-friendly condominium with an explicitly liberal policy framework — welcoming to investors, pied-à-terre buyers, foreign nationals, and parents purchasing for children — which makes it a flexible, practical choice at Financial District pricing.
For buyers, Seaport South combines a full-service doorman program, a genuine downtown-waterfront location, and the flexibility of condominium ownership.
Architecture and unit composition
The 12-story building is a white-brick mid-rise distinguished by horizontal window bands and a large number of corner and angled windows — a legacy of its office origins that gives many apartments strong light and multiple exposures. The roughly 121 residences run from studios of about 510 square feet through one-, two-, and larger multi-bedroom layouts, some with private terraces. Interiors reflect a range of renovation vintages, and condition varies apartment to apartment, driving much of the pricing spread within the building.
Building operations
Seaport South operates as a full-service condominium: a full-time doorman and concierge, a live-in resident manager, a porter, three elevators, multi-floor laundry, resident storage, a bicycle room, a rooftop terrace, central air conditioning, and a street-level deli. There is no fitness center or parking garage. Common charges and property taxes reflect a full-service converted building; buyers should model the full monthly carry and review reserves and any capital history during due diligence, as is prudent for any office-to-residential conversion of this vintage.
Recent sales
As a condominium, Seaport South prices on a price-per-square-foot basis. Recent activity has run in the vicinity of roughly $900 per square foot, with one-bedrooms asking around the $700,000s and two-bedrooms toward $999,000, and closings historically spanning a wide range depending on size and condition. Within the building, floor, exposure, view, outdoor space, and condition drive pricing more than any building average; corner and higher-floor lines with the building's angled windows carry the light-and-view premiums.
Note that some transfers recorded against the building are non-market or related-party entries; arm's-length resales are well documented and are the right basis for comparison.

What to know if you’re buying
Location and flexibility are the draw. A full-service doorman condominium steps from the Seaport, with liberal, investor-friendly condo rules.
Light and views drive value within the building. The angled and corner windows are a distinguishing feature; confirm exactly what a given apartment sees and how it captures light.
Condition drives price. Renovation quality is a primary variable within the building. Inspect kitchens, baths, and mechanicals and price against comparable condition.
Condo flexibility is real. Pied-à-terre, subletting, foreign buyers, and LLC/trust ownership are permitted under the declaration; closings run on condo timelines.
Mansion tax thresholds may apply. At this building's pricing, the $1M cliff can be in play on larger units. Run pricing through the Mansion Tax Calculator.
What to know if you’re selling
Lead with location and flexibility. The Seaport-and-waterfront address and the liberal condo rules are the headline for a buyer pool that includes end users and investors.
Present the light and any outdoor space. For corner, higher-floor, and terraced lines, photography and staging that read the light and the view support price.
Price per square foot against the right comps. Comparable analysis should weight floor, exposure, outdoor space, and condition — and exclude non-market transfers.
