Hi Grace,
Look it the Worcester area, it is closer to an hour with traffic but I house hacked there when I was living in Worcester and working in Boston. There is a ton of development along the mass pike going west and the state is pouring money into Worcester. Most of the buildings are triplexes, allowing for a bigger opportunity if you can find a good deal. I purchased in March of 2016 for 213k, spent 28k over the course of a year house hacking between the three units, and once rented it out was cash flowing $950 after reserves. I sold in early January for 374k.
In the Worcester market, there are plenty of deals to be found as there has been a huge uptick in rents as well as demand. Finding a triplex with good bones and below market rent is not difficult. It gets more expensive the closer you get to Boston, but I would start there. Other areas to look at would include Lowell and Leominster, but I do not think the upside for appreciation is as great in those areas.
