Boston Boom Bust

"While Beacon Hill and neighborhoods such as Dorchester and Roxbury don't typically rub shoulders, the two ends of the Hub housing market may be sharing symptoms of a coming real estate chill, experts say.

Condo sales on Beacon Hill fell nearly 50 percent in March, according to a veteran neighborhood dealmaker.

Meanwhile, mortgage defaults are spiking in Dorchester and Roxbury, while single-family home and condo prices are down, the Herald has reported.

The news comes as the Commerce Department reports a 17 percent March plunge nationally in housing starts, the largest decline since 1991.”
