How can I expect to get a loan at 18?

[Cole Domino]

I have 30k and have a 718 credit score, have worked at some employer for almost a year. I want to get started in real estate but at the moment I do not think my income is enough at 26k expected. The house I am looking at is a 70 thousand condo(est.1987) right down the street from a state school, and has 2 Br and 2 Ba with 1000 sq. mortgage is 600$ 15y and lowest 2 room in the area is 750 but averages 850$.
