I had solid W2 income, no debt other than the mortgages (no car loans, no student loans, all credit cards paid off each month) and all my properties cash flowed, yet a bunch of banks denied me because my DTI was too high.

I am a 19-year college student studying mechatronics but my real passion is real estate and entrepreneurship.

She is supposed to be student.

Looking to buy my first what I think is a rental deal within walking distance to CMU campus, i really like the fact that it was student housing. 

Lawyers are in some ways like teachers, they're drafting contracts, arguing in court, writing letters/memos/opinions, so it's ask them to explain the process of setting up a protection plan.

Looking to buy predominantly for student housing and/or Airbnb

College students could go one way or the other.

I don't get these rent-a-room house setups unless its for college students. 

My expenses and DTI are relatively low, with some current CC debt, student loans, and no car or car payment.

I know some folks getting a 7% ROI in CA now renting rooms separately to college students in a large SFR in Sacramento, so it works.
