Gov. Maura Healey unveiled her ambitious plan Thursday to bring more affordable housing to Massachusetts, a plan some brokers call a start to tackling the housing crisis.

Gov. Maura Healey released a "comprehensive housing plan" Thursday morning, outlining strategies to lower costs and build 220,000 new units over the next decade to mitigate the state's ongoing housing crisis.
