Do I need a Broker's License?

[Account Closed]

I recently started renovating rental properties. (Buy-renovate-hold) and am thinking about managing other people's rental property's as well (small scale not looking to make a fortune just utilize my contacts). I have turned away probably 25-ish people who were interested in renting from me (maybe 15 of which were qualified) so I know demand is there. I just want to make sure before I get too deep in that I have everything I need legally. I would be operating in Iowa.
