Talking to a local loan officer or mortgage broker in your area might uncover some opportunities.
Although some down payment assistance programs have gone away, perhaps there's something locally that you've missed which a mortgage professional in the Plymouth area can help you find.
It sounds like something's changed for you that you're trying to correct since you're already there and you like where you are.
Perhaps you can rent for a short time until you can handle the change or improve your financial situation?
I know that's not the answer you're looking for so consider also checking with a
Realtor for affordable housing you may not be aware of as well as consulting with a local lender for programs you may have missed.
