Good evening, 

Hypothetically speaking, If there was a college student (Mechanical Engineering Major) who had about $35k in his savings, no debt, one semester of school left, and was looking to invest in something beyond the typical stocks portfolio, and retirement accounts (401k, roth ira)... What would you suggest?

This hypothetical student is aware of storage units, and house hacking as some pretty viable options, but isnt sure what else there might be out there. Based on this hypothetical students research, they have narrowed their ventures down to those two options but feels like there is a chance that they may have overlooked better options. 

This hypothetical student is considering finding a mentor for the storage unit/rental property ventures but isnt sure what they would be able to offer in exchange to the "mentor".

Any advice or just general thoughts for this hypothetical student would be greatly appreciated. 

Thanks. (hypothetically of course)
