Tammy La Gorce has an important research piece on p. 6 of Sunday Business July 9 2017 for LGBT retirees: “Finding a welcoming, affordable place to grow old” with the subtitle “Lesbian, gay, bisexual, and transgender retirees ace numerous housing challenges”, link .
One problem might be qualifying for a standard apartment if not needing the special services. As I covered June 24, there are special HUD rules for qualifying for subsidized rent in 55+ (or 62+) centers that usually offer extra services, including some meals and social services. At least one retirement center in northern Virginia has a fully equipped stage theater for plays, often high school or local groups.
Another issue might be that an LGBT retiree might not fit into the social climate of some retirement places (probably more likely to be a problem for men than women).
In Washington DC, the DC Center for the LGBT Community has sponsored activities for retirees and there is some increased interest in the problem with events planned in Arlington by AGLA. A couple years ago, the Arlington library screened an independent film on LGBT retirees.
One observation is that some apartment buildings in some cities (like Minneapolis) have a certain percentage of units set aside for subsidized housing and for retirees. In Minnesota, when I lived there, it seemed there was more interest in modern high rises having very mixed populations, ranging from U of M graduate students or medical students all the way to retirees and some people with disabilities. This seemed to be a welcoming environment.
Update: July 15
I'm told personally that LGBT retirees tend to stay "in the closet" in suburban retirement homes.
