There are many types of 55+ communities. The one I live in is "independent living," which means it's just like living anywhere else, except that it's a gated community, limited to residents 55 or over. But some of the communities are "assisted living," where people get their meals, housekeeping, and a certain amount of medical assistance. I'm sure the atmosphere varies a lot between these types of facilities.
I enjoy living here because it's a friendly and very active place. It's built around a beautiful golf course and offers tons of activities, of all kinds. It's impossible to get bored here. I'm in a hi-rise, which I like the best, because of all the activities right in the building. But some people prefer living in a smaller, standalone house, or a town house. If the community is large enough, there are lots of choices.
Two negatives: Large dogs are not allowed, and for those who live in a hi-rise, no outdoor grilling of food.
Also, my community has a wide spectrum of religions and races, and various national groups. I think that's a big plus. Some facilities are religion-oriented. So that's a thing to be aware of when shopping for a home.
If a facility is older, that could present financial problems, as the residents could experience steep rises in rents or condo fees when it's time to replace the roof, etc. OTOH, the newest places are usually the priciest. So you pay one way or another.
