HI I'm 21 years old and I'm a part time student in college, I've been working in a hospiatal about 5 months I make 11.0/hr during the week n 13 on the weekends. I live at home I have a 200$ a month car payment and a 50$ dentsist payment a month. I'm currently looking for a second job as well. I want to buy a house I really have no credit. Not much in savings.is it possible for me to buy a home.

Its highly unlikely. First, we don't know what home prices are in your area. Second, you need to plan on at least 10% down payment. Probably more with no credit history.

I suggest you wait until you finish school and, in the meantime try to save as much as you can towards a down payment.
