You as a retired person, have a slight advantage over a regular person working a 9-5 job. FHA allows us lenders to gross up your income up to 125% of actual income. In addition, the majority of consumers over 65 have really good credit and very little debt. This is recognized by the underwriter and taken into consideration when figuring out the max debt-to-income ratio. So if you are interested in applying for a home loan, I wouldn't be too concerned.
