Many home owners in North Andover & Haverhill post their for rent listings on Craigslist.
You may find options that aren't listed on real estate websites there.
A word of caution though if it sounds too good to be true it most likely is.
If you find one that you are interested in be sure to ask for the home owners name and if you'de like I can check it with the public records for you or you can do so by going online to the town website into the assessor's record with the address.
Best of luck.
