It's going to depend on the compensation you receive from your future employment once you graduate college. Being able to put a big down payment is fine and dandy, but you have to have proof of income in order substantiate you can realistically pay back that loan.

Additionally, while your credit score is good, the score itself is not everything. Since you're in college, I'm going to assume the only revolving accounts you have/had are maybe your student loans, and maybe a low balance credit card or two.

When looking at risk profiles, creditors really take into account borrowing history and are more likely to approve you or give you better terms if you have a history of loans with higher payments and good payment history.

Since you don't have a lot of those despite good payment history, there's not really a full basis of your ability and history of paying back a loan. So, there's a good chance a lot of institutions wouldn't approve you or you'd have a higher rate.

That being said, not knowing rates this time next year (likely slightly lower), I'll go off of current rates: at a $50k purchase price, $10k down, 7% interest rate, and 72 months, that's a payment of roughly $750 depending on state tax.

My recommendation would be to set up a savings target goal and plan your finances around your future career. Usually, banks will approve you for a max DTI of about 20%, which on a $750/mo loan is $3,750 or 45k a year (not accounting for other debts like your student loans, credit cards, rent, etc).
