College student buying BMR apartment?

Literally the title. I make ~50K/year as a college student. Should I buy a BMR apartment as opposed to paying terrible SF rent? I'll likely live in a studio for the next ~10 years, but I'd like to sell the BMR apartment after 10 years. Also, I may not qualify under income for the BMR apartment post-grad. Is it still legal to buy it now while I qualify?
