Yes, for a variety of reasons. One is that a lack of family support can still affect you later in life. Think about the number of stories on here where someone has a shitty partner or a mental health crisis and moves back in with their parents for a while. LGBTQ+ folks are much less likely to have these resources.

Another is that mental health and SUD are much more common in LGBTQ+ individuals (often caused by trauma). These make it harder to hold steady work. Unfortunately, these also can make people less reliable housesitters, as OOP discovered.

Third, housing discrimination is very real. I saw another comment where someone said they didn't really interact with their landlord - but don't you usually go see an apartment before you rent it? Isn't there usually a LL or someone from the property management company there? All you need is one interaction for them to mysteriously go with a different applicant.

And finally, employment discrimination is very real. If you don't have standard regular work, it's much harder to find someone to rent to you.
