Storage Units

[Tyler Sample]

My passion is to become a full-time real estate investor but will not start investing until after I earn my Bachelors degree. Because I am attending school, I am spending my free time researching investment ideas, strategies, etc. and have come across the idea of developing storage units. What are the pros and cons of investing in these? I do not have experience fabricating or constructing buildings so I would have to consider hiring a contractor, but I have been told storage units are a very fast way of building a cash flow (not sure how steady of a cash flow). Is there anyone that can give me their input? Please & thank you!
