Indian Harbor House has 20 units, and turnover here is slow. That is not a complaint — it is a data point. When a condominium at 630 Steamboat Road comes to market, it tends to generate immediate attention. Buyers who have been watching this building know it, and the window to act is usually short. There are no verified active listings at this time. If you are tracking Indian Harbor House specifically, the right move is to be notified before a unit hits public MLS. The Engel Team monitors Greenwich CT condo inventory closely and can alert you to upcoming availability, including units that trade off-market.
MLS records show 6 confirmed sales at Indian Harbor House. Closed prices ranged from $365,000 to $1,700,000, with a median sale price of $735,000. Unit sizes recorded in MLS ranged from 910 square feet to 9,999 square feet, with a median price per square foot of approximately $426. The spread in both price and size reflects meaningful variation between units — this is not a building where every unit is a near-identical two-bedroom flat.

The most recent sales closed in early 2021. With only 6 MLS transactions on record and nothing more recent, comparable pricing is genuinely thin. Buyers and sellers here need to do real due diligence on unit-specific condition and size — the $426/SF median is a reasonable anchor, but the actual price per square foot varies substantially depending on which unit you are dealing with. The outlier recorded at 9,999 square feet for unit 1C likely reflects a data entry anomaly and should be verified directly rather than used as a comp.
Indian Harbor House is a mid-rise condominium building at 630 Steamboat Road in Greenwich, CT. The address places it in one of the more specific and sought-after corridors of Greenwich real estate — Steamboat Road runs along Indian Harbor, connecting the downtown Greenwich core to the water. A 20-unit building at this address is a genuinely small community by any standard, and that scale shapes everything about the ownership experience. You are not anonymous here. The building is not a large complex with rotating management. The association operates with a tight unit count, which means every owner decision carries real weight. The year of construction is not available in verified records.
MLS sales reflect one-bedroom, two-bedroom, and three-bedroom units across the building’s inventory. Recorded square footage ranges from 910 square feet for a one-bedroom unit up through the larger configurations that have traded closer to 1,900 square feet. Two-bedroom, two-bath layouts appear most frequently in MLS records. Three-bedroom, three-bath units have also traded, with sizes of 1,660 and 1,872 square feet recorded. The building is classified as mid-rise. Specific details on parking, outdoor space, and floor-by-floor layout variation should be confirmed through the association and current listing documentation, as these details are not consistent across all units in available records.
The current HOA fee is $2,465 per month. That is a meaningful carrying cost, and buyers should request the full reserve fund study and the most recent two years of association meeting minutes before making any offer. At 20 units, a single large repair assessment — a roof, elevator system, or facade project — concentrates the cost across a very small ownership pool. Ask for the reserve fund balance and whether any special assessments are pending or have been levied in the past five years.
630 Steamboat Road sits near Indian Harbor, which makes flood zone status a mandatory due diligence item. Buyers must request the current FEMA flood zone designation for the specific building and confirm what flood insurance coverage the association carries at the master policy level. Understand what your unit-level homeowner’s policy is required to cover beyond the master policy, and price that into your monthly cost estimate.
Renovation variation between units is real here. With only 20 units and sales records spanning back to 2016, different owners have made different improvements over different timeframes. A unit that sold in 2016 may have original finishes; a unit that sold in 2021 may have been fully renovated. Do not assume comparables reflect equivalent condition. Request photos from prior sales or a unit walkthrough before making price assumptions based solely on MLS data.
The resale package for Indian Harbor House should be reviewed carefully before closing. Connecticut law requires disclosure of association financial documents, bylaws, rules, and meeting minutes, but the quality and completeness of these materials varies by association. Resale value at this building is supported by the Steamboat Road address and the building’s scale, but thin comp history means pricing a unit accurately requires local expertise rather than a simple per-square-foot calculation. Confirm the owner-occupancy ratio and whether the association permits rentals, as both affect financing eligibility for buyers using conventional or jumbo loan products.
Property taxes at verified sold units ranged from approximately $5,080 to $5,256 per year on the three-bedroom units. Greenwich’s tax rate is 12.04 mills, and assessments are unit-specific, so buyers should request the current assessed value and tax bill for any specific unit under consideration rather than relying on the building-level figure.
Pricing a unit at Indian Harbor House accurately is harder than it looks. Six MLS sales over roughly nine years, with meaningful variation in unit size and condition, means there is no clean comparable stack to draw from. If you are selling, the right strategy is not to anchor on the last closed sale and add a market appreciation percentage. It is to understand exactly how your unit compares on size, floor, condition, and water orientation to the handful of prior trades, and to price from that analysis, not from hope. The Greenwich real estate market rewards correct pricing at launch — overpriced units at small buildings sit, and sitting at a 20-unit building is visible.
If you are buying, the thin comp history cuts in your favor during negotiation if you know how to use it. Most buyers and their agents do not dig into the association financials or the flood zone specifics until they are already under contract. Doing that work before you make an offer gives you real leverage. Browse current Greenwich homes for sale to understand the broader market context, and contact The Engel Team directly to discuss what is available or coming available at Indian Harbor House specifically. Off-market monitoring is often the only way to buy at a building this size before it hits public inventory.
