Time Spent Managing a Property

[Eric Jelen]

I want to start investing by buying a residential multi-family and living in one of the units.  I also would like to take advantage of my company's tuition reimbursement program and get my masters in engineering management. I know this can vary greatly, but I was curious how many hours it takes a month or week to manage 1 unit? Do you think it is doable to work a full time job, go to school part time, and manage a property? I don't know how passive managing a property really is.
