Has anybody financed a house using exclusively grad plus loans?

[John Cena]

Hi! I have never purchased any property before so I'm quite unfamiliar with all things real estate. So I begin graduate school this May and rent near my school is pretty expensive. For only a couple hundred dollars more monthly, I can purchase a beautiful brand new home 10 minutes away from the university. The one caveat is that I will be unemployed during graduate school, and I will be solely surviving off of grad plus loans for tuition and mortgage payments. My graduate school is pretty cheap and I know that the grad plus loans that I can pull will be able to cover a mortgage payment and my tuition. My girlfriend will be able to cover groceries and other bills. 

I believe that purchasing a house now would be far more beneficial to me rather than paying rent. Even if I move back home, I can sell it when it appreciates in a couple years or even keep it to rent to other tenants. 

I feel like my situation is pretty unique and I'm hoping I can get some advice on how to navigate this situation! Has anybody ever done something like this? Thank you!
