This isn't 2011-2013 days but many people are stuck in that time period STILL.As I finish my licensing study, I'm very grateful I chose this route as opposed to being a one trick pony.Wholesalers did themselves in by their method of operating.  

I am not an expert here but my thought is that you would learn a lot by getting your license and have more credibility in the industry at large so if your time and finances allow- get that license:)

Quote from @Sebastian Bennett: I've been thinking about getting a real estate license.

Just making sure, you have your rental license?

Or does one need a special license / need to open a company?   

It's very cheap and not difficult to maintain bond/license/insurance.

The best advice I can give you for studying for you license is to voice record yourself reading questions and answers on notes cards.

If you're wanting to wholesale, drop your license. 

If a state requires a license you need a license IN THAT STATE.

Up until November, actively licensed VRD (Vacation Rental Dwellings) could transfer one time to the new owner.
