We drew on our past experience more than anything. I had a background in business. Hubby had a background in construction. We just - - - figured it out.
Self Storage really isn't that hard. It isn't as complicated as apartments.... you don't have dogs peeing on the carpet and people getting threats of power shutting off in February. You don't hear the sob stories about skipping Christmas this year because the ex decided to hop a train to New York and take all the credit cards with him. If they don't pay - you lock them out and you are done with it. Can't do that on a residence.
You don't have the overhead of many other traditional brick n mortar businesses either.
Having said that - - - there really isn't much out there. There is a book, I think it is called "How to Make Money in Self Storage." It is a really paper thin book and it is primarily designed as an upsell tool. (The author is a Self Storage Consultant).
There is a site:
www.selfstorageguide.com It is okay..... nothing special. More like a resource for current owners. People post on the forums - questions like "I have a customer that hasn't paid in 2 months. What should I do?"
