This is a big deal to me. My parents now live in a 55+ HOA, and they love it. They have no need for outside maintenance, painting, power washing, gardening, etc. Given they live in S.Fla, my sister and I were very glad for this, as we weren't sure if my Dad was ever going to give up mowing the lawn otherwise.
They have a nice clubhouse and bocce courts (they play). They have onsite pickle ball and tennis courts, a security gate, and plenty of neighbors in their peer group.
Their HOA fee also includes their cable/internet.
In S.Fla, many of these communities are quite upscale, newer builds, but cheaper than their comparable non-55 neighborhoods, which would all still be HOA. So a SFH 700k house can be found for less than 600k, but it's very easy to spend well north of 1M especially for a bigger home, lake views, etc.
