FHA requires a 500 credit score, and most FHA lenders minimum score requirements tend to be 600, 620, or 640 - with FHA anything less than a 580 score requires a 10% down payment
VA financing has no score requirement, but VA lenders score requirements are similar to FHA's.
USDA financing has no score requirement - however if you go through a lender most will have 620 or 640 minimum scores, but if you go Direct to USDA they do not have any minimum score requirements, but it takes a little bit longer.
Fannie Mae & Freddie Mac require a 620 score.
Credit score isn't the only item considered though, what is on your credit report is equally as important. If there are late payments or delinquent accounts in the last 12 months when you apply then that can really curtail your chances of qualifying.
USDA financing is 100% financing in rural areas, and there are two versions, Direct & Guaranteed. Direct you go direct to USDA, Guaranteed is where you go through a mortgage lender and at the end they send it to USDA. Guaranteed allows higher income limits, but the underwriting requirements are tougher. http://eligibility.sc.egov.usda.gov/eligibility/welcomeAction.do has the income & geographic eligibility limits for USDA - Indio isn't eligible but Coachella, Thermal, Mecca, etc. is.

Have you checked your credit to see what is bringing your scores down?
If you need advice or have questions I'd be happy to help.
Banks use the middle score, so depending on where that is you may well get approved. It's more than just scores though, why do you have the low numbers? Have you taken steps to resolve the issues?
You can do some simple credit repair that will improve your odds of getting approved and qualify you for better rates & programs.
Meet with a local full service lender and see what they recommend. When a lender pulls your scores, they may be different from what you have. Only a lender looking at your complete file will be in position to tell you whether they have a loan for you. Best of luck.
