FHA may be the best way to go in general. 3.5% down payment,, and that can actually be a gift from a relative if needed. Also, the seller can contribute up to 6% of your closing costs.
Mass Housing.org or .gov would be another website to check out to see what the state of Mass might do and allow. If you'd like to chat, please contact me. I am licensed in Mass for mortgages, and I'm a multifamily owner myself. Thanks and good luck,
