The tax credit may be over, but there are still some incentives available for buying in Wiorcester.
There are companies providing incentives to their employees- Hanover insurance, Umass, St. Gobain, assumption college, and others actually give employees money at closing. here's a link: http://www.buyworcesternow.com/participating-employers
There are also programs available if you purchase within designated areas of the city to assist with purchase & renovation of property.
