I mean, I suspect it's mostly be people with mental health issues, but I rarely see any evidence for the "who'd been homeless anyway" part. I know plenty of people with mental health issues who aren't homeless. Most of them work productive jobs and support themselves.
Mental health issues are usually manageable if you have the resources to manage them.
If homelessness is increasing, then it seems likely that something's causing the increase. If the cause is mental illness, something's causing that mental illness to be more prevalent or less manageable.
High rent seems like a decent hypothesis of it being less manageable.
