I believe it a good opportunity because it is next to a university and is rented by students.

I own a 3/2 standalone SFH in University Park, and the tenant is interested in buying.

Although I do not know your area, thus I cannot point you to the best areas to look for these properties in, I can tell you one universal thing I have learned since restarting my Property Investing, and that is there are a heck of a lot of people within 30 minutes from where you live now that can help you. 

and look for a ARM accredited manager.

Sorry but dealing with only accredited buyers is in everyone’s best interest.

I'm under the impression BARRR (A for advertise) is universal.  

I saw that I used a universal and you almost never should use them.However, the way @Nick Tzenevrakis described his situation it is a great way. 

Things like medical and universities are stabilizing forces.

Stay away from the west side of University, nothing but trouble high maintenance people/property.

I would look into the area around Chapman University for a 2-4 unit property, given all the growth and revitalization around the university.
