Looks like a pretty good investment to me in greater...

...Boston area. HOA of $280/month and property tax of $1,200/month are fairly low in Boston area even if you are quite up north.

Did I sense you are renting to section-8 tenant (since you mention being able to increase rent every year)? $1400/m is decent if not good money in your case. Not all S8 tenants are bad, either.
