Irrelevant, no 18 year olds have enough money to buy a house (and if they do they're bourgeois so fuck 'em)
get married
Honestly people shouldn't be able to get married until they've been living together for a couple years at least which would put it over 20 (but I also don't view marriage as important so :shrug-outta-hecks:). Ideally, I'd go with 25 because that's when people are fully mentally developed.
do sex work
I know that I'm to the right of a lot of people here on this but I'd agree with this. I'd go with 25 again.
join the military
Nobody should be able to join the military, regardless of age
