Good luck with your decision, Scuba.
I considered 55+ communities, but I decided against them. For me, it boiled down to four main reasons:
1. Living under an HoA. I love my independence, and having an HoA dictate what I can do with my own property would bug the crap out of me. While I understand some HoAs are fine/reasonable, I've heard too many HoA horror stories. Not just appearance-related trivia, but other factors, too (e.g., rapidly rising fees, poor decision-making).
2. The 3 to 1 ratio of women to men. I'm a single man, and I don't want to be surrounded by a field of grannies. No offense to the grannies amongst us. I like talking to older women; I just don't want to live in a community dominated by them. And I suspect that most of the men will be married, so I'll be the odd man out. I'm used to being the odd man out, but I don't need to go seeking it.
3. I have heard too many complaints about the "high school mentality" of people living in 55+ communities -- gossip, cliques, busybodies, drama. Granted, you can find these things in most neighborhoods to some degree, but it seems -- at least based on the frequency of reports -- that these elements are amplified in (some) retirement communities. I suspect it is because they have too much time on their hands. And as I heard someone quip, "most people don't mature; they just age."
4. Most 55+ communities do not have enough amenities that appealed to me. I'm not much into tennis and pickleball, for instance. It wasn't until I got to the very large communities that I found enough amenities to appeal to me. In most cases, I would be paying large fees for amenities I would not use.
To be fair, many people clearly love their 55+ community. I hope you become one of them, if that's the direction you head. I'm not claiming that all 55+ communities have the problems I mentioned above. I'm sure that many are just fine. However, for me, the cons outweighed the pros.
