Property management is a practical field to enter if you are worried about economic stability. It’s incredibly recession proof, as housing is a necessity and therefore people will be renting properties regardless of the economic conditions. But you can’t just decide on a whim to be a property manager — it has legal requirements and best practices.
In the vast majority of cases, being a property manager requires a broker’s license. There are certain cases in which it doesn’t, but they would not apply for rental properties, which are the bulk of managed properties. If you don’t want to get a broker’s license, though, you can consider managing commercial properties, but there would still be many restrictions.
First Tuesday, a real estate journal, has assembled a Property Management 101 infographic, complete with links to articles and PDFs for additional explication. This contains more specific details about the legal requirements, other applicable laws, and market information.
