I can see the value of getting a condo if you were going to pay her rent anyway. Very few college students are fully self sufficient, usually they use some combination of savings, work, parents, loans and scholarships to cover the costs. I knew lots of students whose parents paid their tuition and rent and living expenses so they wouldn't have to work and they could focus fully on their studies and I don't think that causes "class divisions". However, I think that the younger you are forced to fend for yourself, the better you get at it, and lots of those kids who never worked ended up back at home after graduation. If you buy the condo and are able to make some money from renting out another room and sell it after for the same or more, you'd probably save over paying her rent the whole time, if that's what you'd be doing otherwise.
Some parents don't believe in helping their kids at all, some think that both should contribute equally, and others believe that if you can you should, none of those options are more right or wrong, but they are dictated by family values and financial means. If you've decided that you will contribute, you just have to determine what is the most efficient way for your family.
That being said, I think living in a dorm in first year if you are from out of town is a great idea because it is a really good place to make friends and start building relationships, and a place to find potential roommates for the next year, an easier move back home if this college doesn't work out, and less pressure (I have this condo already I have to stay even though I hate it kind of pressure). So I think holding off until second year for the condo might be a better option.
