My husband ran 2 business and graduated in 5 semesters (with a 3.80).  

my first rehab took all summer while i was in college...actually into fall semester, i still was washing dishes out of my bahttub bc i didn't have a countertop in the kitchen....i paid too much for the house, overdid some of the rehab, used the wrong contractors (read cheap, but not professional)..i still have it as a rental, but man did i learn a lot over there!

I knew after my first semester that I wanted to become an entrepreneur.

If you are off-season for getting student tenants though I  have had success with changing the lease end date to correspond with the semester end date and offering a short term rental or a few months longer. 

I moved from my old place because I wanted to make sure I did not have to move during the semester, as I am a grad school student. 

I haven't had the chance to take any of my RE classes yet unfortunately, I changed majors from education so am about a semester or so behind in my current degree despite being a junior. 

Being that it is student housing your vacancy may run really low .... or really high ... depending on the semesters fall and how the lease is structured.  

But Baltimore is one of the cities I'm considering for my 1st investment because a) NYC where I live is too expensive a market for me b) my girlfriend will be attending Johns Hopkins next semester so I'll be spending a lot of time there.

You could do an entire semester on the uses and abuses of CAP rates ...

Midway through the lease, and at an upcoming new semester, they didn't get the course load they had received in the past.
