@Thomas Barksdale
I live in Bradford, MA myself and currently own one triplex (Three family building). Reading your post made me feel worried about success for you as it seems that you haven't done a whole lot of research on the topic...
Correct me if I'm wrong, but it just reads as though you're not that familiar with landlording. MA isn't a forgiving state to just pick it up and go, especially without familiarizing yourself with the intricacies that come with this state. (Rules, Laws, Best Practices)
The other problem that you are going to run into, is that 200k won't get you anywhere close to a duplex or three family in Haverhill. We bought ours in December for 400k, and the market has only climbed since then. You may want to focus on getting your finances figured out before going into this game.
It sounds as though you are hoping to get into Landlording as a way to have someone pay for your house, that you can't necessarily afford, that would be a huge mistake in my mind, as you will have serious issues in the times that you don't have tenants...But maybe I just play on the conservative side of things.
A different way to start would be to try wholesaling, or helping other investors find deals to start learning from them as to what is needed to be successful in this game.
