Can I survive as a student landlord?

[Sam G.]

I've read a lot about landlords investing in student rentals but haven't found much about landlords that become students. 

I have a 3 unit that cash flows very well for me with great tenants and minimum maintenance. I'm strongly considering going back to school for a career change in order to increase my future income and buy more real estate. I have some money saved up in the event of evictions/repairs/turnovers but I'm unsure if it's enough to rely on the property to pay for itself through cashflow and a small savings. 

I won't be working while in school so this has led me to contemplate selling a cash flowing property., which I hadn't planned on doing. 

What do you guys think? How much savings would you need to have in order to feel safe? What are some factors to keep in mind?
