Buying Investment rental property in graduate school

[Lucas Craft]

Hey guys. I'm new to REI and am eager to get into a property while in graduate school. The problem is that I don't have a W2 income because I'm a full time student. I know that debt-to-income ratio is a major factor that banks consider before giving out loans and since I have no income and a decent amount of debt I am wondering if it is possible to still get a loan from the bank. I will be able to provide a 20% down payment but I'm not sure if that will be enough to make up for the poor debt-to-income ratio. Would a rental property income count towards the income part of the ratio evening out the DTI a little? Thanks!
