You can absolutely purchase a property with this type of retirement income and these credit scores. My name is Jake Johnson, and I work for a lender that is in 29 states including New York and Florida where I am licensed in both. Many lenders will have trouble with a 600 credit score, however, we are what is called "Ginnie Mae approved" and an expert in lower credit score loans. I work in Manhattan, so please give me a call at any time at 646-737-4481. I look forward to planning out this move into retirement for you!
