How Much Have Greenwich, CT Home Prices Really Gone Up Since 2019?

If you own a home in Greenwich, or you are thinking about buying one, you have probably heard some version of this: prices have gone up a lot since before the pandemic. That is true, but "a lot" undersells it, and the details matter more than the headline.

I have pulled the numbers straight from the Greenwich Multiple Listing Service, going back to 2019, across the four markets I work every day: Cos Cob, in-town and back-country Greenwich, Old Greenwich, and Riverside. The median single-family home price has risen steadily in every one of them. Depending on the neighborhood, that increase ranges from 67 percent to 120 percent. In plain terms, a home in Riverside that sold for $1.71 million in 2019 sells for closer to $3.77 million today.

That is not a typo, and it is not a fluke of one hot year. It reflects seven years of a market that has consistently favored sellers, driven by a simple imbalance: more buyers wanted homes in Greenwich than there were homes available to sell them.

The other half of the story is speed. In 2019, a single-family home in Greenwich sat on the market for an average of 227 days, well over seven months. Through the first half of 2026, that average is 63 days, a drop of 72 percent. Homes are not just selling for more. They are selling in a fraction of the time it used to take.

I have worked in this market since 1985, and I have seen a lot of cycles. What I have not seen before is this particular combination: sustained price growth across every single neighborhood in town, alongside a genuine and lasting drop in how long it takes to sell. That combination tells you something structural is happening here, not just a temporary spike.

Which Greenwich neighborhood has appreciated the most since 2019?

Riverside leads every other Greenwich market on price growth. Its median single-family price has climbed 120 percent since 2019, from $1.71 million to $3.77 million through the first half of 2026. Sales volume in Riverside actually peaked back in 2021 at 163 closings and has since settled to 38 through June. What stands out is that prices did not follow volume down. Fewer transactions have not meant softer pricing.

Cos Cob is close behind at 102 percent, moving from $1.07 million to $2.17 million. I would call this the most underappreciated appreciation story in town. Cos Cob has historically traded at a discount to its neighbors, and that gap has closed in a meaningful way.

The combined Greenwich zip codes, spanning back country to in-town, are up 112 percent, from $2.04 million to $4.31 million, and remain the most active market by volume in this report.

Old Greenwich shows the smallest percentage gain at 67 percent, but do not mistake that for weakness. A move from $2.10 million to $3.51 million is still a substantial gain, and Old Greenwich's school district and village character continue to command a premium that does not depend on a heated market to hold up.

Why are homes in Greenwich selling so much faster than they used to?

In 2019, the average single-family home in Greenwich took 227 days to sell, the better part of a year once you factor in negotiation and closing. By 2021, at the height of pandemic demand, that number had already fallen to 128 days. It kept falling from there. Through the first half of 2026, the town-wide average sits at 63 days, a 72 percent reduction from where it started.

This is not a one-year blip. The number has held in a similar range for several years running, which tells me buyer demand has not cooled off the way some headlines suggest. A well-priced home given its location and condition in Greenwich, in any of these neighborhoods, is likely to receive serious interest within weeks, not months. For sellers, that changes how you should think about pricing strategy and negotiation leverage from day one. For buyers, it means the days of casually browsing for a year before making a decision are largely gone.

What is happening in Greenwich's condo and co-op market?

Condos and co-ops in Greenwich have followed a similar trajectory to single-family homes, though the numbers look different. The median condo sale price in 2019 was $687,000 for the full year. Through the first half of 2026, the median is $1,095,000, a 59 percent gain over seven years.

That is a meaningful shift for a segment of the market that many buyers have historically treated as a stepping stone toward a single-family home. Four of the first six months of 2026 posted medians above $1 million, and January's figure of $1,320,000 was the highest January on record in this dataset.

Days on market tell a similar story to single-family. In 2018 and 2019, condos routinely sat for 150 to 370 days depending on the month. By 2024 and 2025, the town-wide average had settled to somewhere between 54 and 57 days. Through the first half of 2026, it is 55 days. What used to take the better part of six months now takes under two.

Closings are on pace too. With 93 closings through June, the condo market is tracking to exceed 2025's full-year total of 174, and new listing volume is running ahead of last year's pace as well. Supply and demand are both rising, and prices are following.

What does this mean if you're thinking about buying or selling in Greenwich right now?

Whether you own a single-family home or a condo, the direction has been consistent since 2019: values are up significantly, homes are moving faster than at almost any point in the past decade, and inventory remains tight across nearly every price point.

I do not think that means every price is the right price, or that timing does not matter at all. It means that trying to guess the exact bottom or the exact peak in this market has cost more clients money over the years than it has saved them. Greenwich's fundamentals; low property taxes, constrained supply, strong schools, and a direct line into Manhattan, have proven durable through a financial crisis, a pandemic, and several interest rate cycles since I started doing this in 1985.

If you want to know what these numbers mean for your specific property or your specific search, that is a conversation, not a spreadsheet. I have represented more than 500+ clients across over a billion dollars in transactions, and I would be glad to walk through where you actually stand.
