Boston is EXTREMELY expensive to live in. Even places that are just on the outskirts of Boston charge an obscene amount of money. In Woburn, which is like 20 mins from Boston, you will be able to find a studio apartment the size of a closet for about $800 a month- no less. For a good sized two or one bedroom apartment you are looking in the range of $950 - $1500 a month WITHOUT utilities. Boston is a very very very expensive place to live in- it is not affordable with a $12 an hour salary.
That doesn t sound like a good plan; find the job first. look on Monster.com, etc. to get a feel for your area of (work) interest in Boston.
