Patti and Ed are right.... depending on where you are looking to purchase - a USDA loan is a seldom used product that could be another viable option... 102% financing, below market interest rates, NO mortgage insurance. but--- you have to fit the "box" - be in the correct county, 620 + credit score, debt ratio under 42%, two year job history, three open trade lines.... if you fit the box - a USDA loan can not be beat -

are you looking to purchase or refinancing?
MyCommunity maybe zero down but you will need to have a 620 to avoid High PMI costs.
There maybe other first time home buyer programs that can help you.

Also, you can try FHA with only 2.25% down...and they dont have a credit score requirement.
If you're looking to refinance ...you can look into the FHA Reverse mortgage

The My Community Mortgage loan may not be the best solution. FHA loans could be a better fit. However, as a mortgage professional I'd be happy to find the best program to fit YOUR needs and accomplish YOUR goals. You can reach me at 704-651-8704 or visit my website below.

You are much better off looking at an FHA loan if you are able to qualify. It is not credit score driven, but you need to show you have a "willingness to repay" So that means the less recent the lates on your credit the better, and

My Community Mortgage can work in a similar way, but there have been a ton of restrictions coming down on it lately and the rates are about 2% higher than what you can get on an FHA loan right now. My Community also has score requirements and is not as flexible with your credit situation.

If your rent has been on time and you have good explanations for why there are issues with your credit, FHA can be a great program. I don't know that there is any real purpose for My Community loans in the current environment.

Good Luck!
