Can I use student loans to pay my mortgage payment as a living expense?

I want to buy a house now while the rates and house prices are low, but I plan on entering grad school to become a physician assistant within 3-4 years. The program takes about 2 years, and I would probably get a $75k salary job right out of school. Does anyone know if I could get a student loan that would allow me to pay a $1k monthly mortgage payment as a cost of living expense? I have great credit in the high 700's.
