I would say the opposite is true.
Mature couples pose very little risk to a property owner. No worries about loud parties, or friends running in and out, not to mention mature people manage their finances better so they are low risk for skipping out on the rent.
Providing your social security income is enough to meet the monthly rent and other utilities, and your credit is in decent shape, you may win hands down over your younger counter parts.
Best of luck to you!!!!!
