Riverstone Condos in Greenwich, CT

Riverstone Condos for Sale

Riverstone is a 43-unit townhouse-style condominium community at 69 Riverdale Avenue in Greenwich, CT. With only 43 units and a buyer pool that understands the Greenwich value proposition, turnover here is slow. Units do not sit long. If you are tracking this building, the practical move is to get on a watch list rather than wait for a Zillow alert. Contact The Engel Team’s Greenwich real estate practice directly to monitor availability, including any off-market units that surface before they hit the MLS.

The table below shows the most recent verified sales:

The spread between the lowest and highest confirmed sale, $730,000 to $975,000, is meaningful in a building this size. Unit configuration, floor level, square footage, and interior condition account for most of that spread. The 2-bed/4-bath units in the 2,200–2,400 square foot range consistently clear $850,000 or higher. The 2-bed/3-bath units, particularly the smaller floor plans closer to 1,936 square feet, anchor the lower end of the range. Any buyer using these comps for offer strategy should verify current HOA financials and property tax assessments, as both have varied across units.

About Riverstone

Riverstone is located at 69 Riverdale Avenue in Greenwich, CT. The community was developed between 2007 and 2013, making it a relatively recent build by Greenwich standards. Forty-three total units in townhouse format give it a scale that feels more residential than institutional. That matters in Greenwich, where the alternative condominium inventory skews toward either large high-rise buildings or small converted properties with aging infrastructure. Riverstone sits in between: purpose-built, consistently configured, and small enough that owners tend to know their neighbors. For buyers considering Greenwich CT condos as a category, Riverstone represents the newer, townhouse-style end of the market.

Homes and Layouts at Riverstone

Every unit at Riverstone is a 2-bedroom condominium in townhouse configuration. Verified sales data shows two floor plan groupings. The larger units run 2,200 to 2,456 square feet and carry 2 bedrooms and 4 bathrooms, meaning multiple full baths across floors rather than a standard 2-bed layout. The smaller units run 1,936 to 2,215 square feet with 2 bedrooms and 3 bathrooms. The townhouse format means vertical living across multiple levels, with entry at grade level rather than a corridor-and-elevator setup. For buyers coming out of single-family homes, that distinction matters. The entry experience, private outdoor space potential, and absence of shared hallways are genuine selling points. Parking and specific outdoor configurations were not verified in MLS data and should be confirmed with the association directly.

What Buyers Need to Know

The current HOA fee is $500 per month, which is consistent with the majority of recent MLS sales. One outlier, unit 301 sold in late 2022, shows a $350/month HOA fee, which may reflect a timing difference or a data discrepancy. Confirm the current assessed fee directly with the association before making any offer. Property taxes across verified sales run approximately $5,077 to $6,824 per year depending on unit size and assessed value. Greenwich uses a mill rate of 12.04, so buyers should request a current tax card for the specific unit they are targeting rather than relying on an average.

Because Riverstone was built between 2007 and 2013, the building systems are relatively modern but not new. Any buyer should request the association’s reserve fund study and review the most recent budget for capital contributions and any funded or unfunded special assessments. A building of 43 units has limited margin if reserves are underfunded and a major repair is required. Ask for at least two years of meeting minutes in addition to the reserve study.

Resale potential at Riverstone is supported by consistent transaction history across 20 MLS sales, which is strong for a 43-unit building. That said, resale pricing is sensitive to interior condition and unit size. Buyers who renovate kitchens and bathrooms to current finishes have recovered that investment in the data. Buyers who hold units in original condition compete at the lower end of the price range. The resale package for any unit should include HOA financials, reserve disclosures, meeting minutes, and the current master deed and rules. Greenwich condo law requires sellers to deliver these documents; build review time into your offer timeline.

Rental restrictions, pet policy, and owner-occupancy ratio are not verified in available MLS data. These details must be requested from the association directly. For buyers using financing, the lender will independently verify the owner-occupancy ratio. Warrantable condo status affects financing options and should be confirmed before proceeding.

Buying or Selling at Riverstone

If you are buying at Riverstone, the comp set is thin enough that offer strategy requires real analysis, not just a price-per-square-foot estimate. The $245 gap between the lowest and highest verified sale per square foot reflects unit-specific variables that a surface read of the data will miss. The Engel Team works with buyers at Riverstone on valuation, off-market unit identification, and offer positioning relative to the building’s actual transaction history.

If you own a unit at Riverstone and are considering a sale, the same comp depth that gives buyers pause is your leverage as a seller. With fewer than five sales in most recent 12-month periods, a single well-priced listing sets the market rather than responding to it. Pricing strategy here is not formulaic.
