If a hilltop home was a potential purchaser's goal these are some estimates we got for professional work:Getting power to the hilltop will cost about 50-60k according to the local power company. 66k for overhead lines, 52k for buried (not including trenching). $3600 for a septic permit & design about 50k for sitework (very long driveway), though foresters have noted the potential for NRCS funding for road improvement and invasive species management (i.e. clearing the 8-acre area which has blackberry bushes galore) which we are in the very early stages of looking into. 

That said, the world of midterm rentals is much broader than just travel medical professionals.

I am interested in purchasing a 3-4 BR home in Loma Linda (close to the University and hospital) and renting out the individual rooms to students and professionals of LLU.I know currently the market is not great but I was wondering:- How is the demand for housing among students / professionals?

I definitely encourage you to visit whatever market you plan to invest in to familiarize yourself with the area and connect with local professionals.
