Hartford County’s hot housing market in 2020 was spread throughout the region with few exceptions, as the pandemic forced many to work at home and urban dwellers in New York City and elsewhere sought homes in less crowded places.

An analysis by The Courant of data provided by SmartMLS, Connecticut’s statewide multiple listing service, shows that two-thirds of the county’s 29 towns and cities had double-digit percentage gains in single-family home sales compared with 2019. All but five saw some increase, with only one town, Windsor Locks, experiencing a double-digit decline.

The top 10 municipalities, led by Burlington with nearly a 50% increase in sales, all had few single-family houses on the market. Buyers were forced to pounce and, in most cases, paid at or near the asking price, sometimes more.

Across Hartford County, sales of single-family houses in 2020 rose 14.3% compared with a year earlier, SmartMLS data shows. The median sale price — where half the sales are above, half below — rose 10.5% to $257,000, according to SmartMLS.

“COVID-19 gave people an entirely new perspective on the importance of family, home and a critical work/life balance,” Michael Barbaro, board president of SmartMLS, said. “And whether that meant trading apartment life in the cities for a house with a yard, or simply moving to a home that better suited their new normal, Connecticut was a natural fit.”

The surge in sales was particularly eye-catching when the state had been struggling to regain its footings after the 2008 recession.

Carl A. Lantz III, a real estate agent at Coldwell Banker Realty in West Hartford, said low mortgage rates combined with a surge in demand by buyers seeking new houses to accommodate work-at-home lifestyles and, to some extent, those fleeing urban metropolitan areas like New York City.

But the pipeline of houses in Hartford County coming on the market did not match demand. Would-be sellers were enticed by a market where appropriately priced houses were selling at or above list price. But some remained on the sidelines worried they wouldn’t find another house in time and perhaps be forced to move twice, once from a temporary space, Lantz said.

“The market conditions that we are seeing now — as far as I’ve seen — I’ve never seen before,” said Lantz, whose family has been in the real estate business for four decades. “So you had a dip interest rates, a dip in inventory and then a huge increase in demand.”

Among the top 10 municipalities, inventory ranged from 1.4 months to 2.4 months, extremely tight when considering a market is said to favor neither buyer or seller at a six-month supply.

In January, Lantz said there are typically about 200 single-family houses on the market in West Hartford. There are days, he said, there may be 40 or less.

All the ingredients were in place for a “feeding frenzy,” as one real estate agent described it, when a property does come on the market, an atmosphere that is expected to continue well into 2021.
