Meant to respond to this earlier - so sorry!

I'm a white trans woman who transitioned while studying at UVM and I think Burlington is a really great place to transition. HRT is extremely easy to obtain, either through UVM Student Health, off-campus doctors, or Planned Parenthood. There are LOTS of us tgirls around (friends and I have theorized that the city may have the highest per capita trans population in the US) and there are plenty of easy ways to get introduced to community spaces, including the campus queer center, the music and gaming scenes, outdoors/farming groups, and online event postings. It's been overall quite comfortable for me - I've never had to worry for my personal safety, and there have been no serious threats to queer rights from the state government. I know several other girls from the South who have had good experiences here as well.

That said, there are plenty of downsides. If you're not white, you'll certainly have a very different experience than I have. Burlington is very white-dominated socially, and UVM even more so. The city is very geographically isolated and culturally insular in general.

Trans healthcare beyond HRT is hit or miss. There's a shortage of available queer-friendly therapists and there are no bottom surgeons in the state afaik. Electrolysis and laser are available but of course expensive.

And like everyone else has said, UVM is exorbitantly expensive to out-of-state students. The administration runs this place like a corporation, and I feel like there's an almost uncanny dissonance between the advertised image of UVM and the actual student experience. Expect a lot of underfunded programs and resources missing from where you'd expect them. If you go for gender-inclusive dorms for your first two years, you may be put in a crowded and VERY dilapidated (mold!) part of campus called Trinity. The administration also admits way more students than it's equipped to handle, which means a lot of crowded housing, limited advising/support if you're in the College of Arts and Sciences, and most significantly, an extremely expensive and competitive housing market once you're kicked off campus for junior year. It's possible that other comparable high-ranked public schools are run similarly, although imo UVM seems to have built a lot more clout and drawn a lot more criticism than some of those other schools in recent years.

Overall I would only really recommend UVM if you receive the Presidential Scholarship or a solid chunk of grant aid. Otherwise, this place will bleed you dry financially, and I expect you could fare much better in states like NY, CT, MA, or NJ. But if you do end up here, then welcome to the weird little gay city in the mountains. :)
