For my own Buy and Hold strategy I have turned to something that is truly passive, and with instant diversification.  

If you can find a great deal where you gain instant equity via buying below appraisal value, you are already ahead.

Here is what happened to me when I went from CC to UC Berkeley (it'll be UCLA or UCSD in your case).BAH instantly went up, a lot.

Trying to do that would probably create instant problems and liability.If you have them sign an agreement stating that the basement is not to, and will not be used for sleeping quarters, it is possible that you wouldn't be held liable for them misusing your property.

Also refresh your calendar often.If you have instant bookings enabled it will also help.Search your area on VRBO and see what the competition looks like.

Let me know if you would like me to set up an MLS search with instant alerts.My one word of caution is that Massachusetts tenant/landlord laws are tilted WILDLY in favor of the tenant.  

When I thought to myself about what I could do with my learned skills in the construction trade and my want for my family's future to be as bright as possible, I instantly thought of real estate of something I could put my focus on to help me now and in the future.I am building a short term plan to get started by flipping my first home purchase and could use all the pointers I could get from people in the area.

INSIST upon a petty cash fund for instant approval of repairs under $xxx and an itemized Purchase Order for those  that exceed that amount.Also insist upon review and accept/denial on all applications for tenancy.These go a LONG way to keep everyone on the straight and narrow!

Data plans on phones provide instant, real time email.  

For an SFR, the typical buyer will want to occupy, so give lots of notice of intent to sell prior to the lease termination - - time your listing to this event.For an MFU, these are clearly investor properties, so you still give the notice but sell with tenants in-place for the instant ROI to the new buyer.
