Of all the condo sales during the third quarter, Back Bay easily led the top 20 with 12 coming from this part of the city. The 61-story One Dalton Four Seasons dominated the sales chart again with seven sales in the top 20. This 724-foot twinkling tower generated half the top-10 sales alone.

The Boston condo real estate market came back to life in the third quarter after suffering a big downturn earlier in the year largely due to the COVID-19 pandemic. Throughout the spring, sales began to bud and during the summer, sales bloomed.

According to LINK, 844 condos sold during July, August and September. That’s up from the 539 vended during the prior three months. Surprisingly, compared to last year’s third quarter, the total number of sales increased by two.

The number of homes on the market also grew during the third quarter. During the worst of the pandemic early in the second quarter, the number of available homes dwindled to 243. Inventory rebounded from 291 available at the start of the third quarter in July to 377 at the end of September – the highest number of units available in the city so far this year. Although this trend is a good sign that the housing market is on the rise, the market inventory is not as strong as it was when the third quarter of last year closed with 563 condos available.

Of all the condo sales during the third quarter, Back Bay easily led the top 20 with 12 coming from this part of the city. The 61-story One Dalton Four Seasons dominated the sales chart again with seven sales in the top 20. This 724-foot twinkling tower generated half of the top-10 sales alone.
