Anyone Investing in Self Storage Units?

[Tyson Lee]

I recently came across a small self storage complex that is for sale. I have not given these much thought but I do think it could be a great investment. 

I have a few questions for those who currently work with self storage. The complex I'm looking at is small and consists of 32 units that are all 10'x15'. It's in a small town of 3,000 people and was built in 2002. Here's the kicker... I live 500 miles from where these are located. Is this viable? What kind of issues do you run into with self storage? There is not a gate or fence on the property and there is no electricity. Just in the beginning stages of thinking about this and would like to hear the pros and cons. 

Thank you
