Hi Pedro!
I am also very new to this but if you look through the forums, you will find this question is asked a lot. The short answer though is no- you don't have to have your license to wholesale. The reason is, you are not selling homes, you are selling the rights to a contract. There are many opinions however on if you should or shouldn't. I suppose it is really up to you and your goals of what you want to do. I am just starting and have gone through about 20+ realtors and still haven't been able to find one who is experienced and willing to work with me and help guide me. I suppose I can't blame them though- it's not their responsibility to make sure I know what to do! I have found one realtor who I am working with that has done her best to do what is needed but she is also still relatively new so we are learning a lot together. I have contemplated getting my license though just to be able to have access to the MLS and other information that could help. It is a slippery slope though and I think the main thing to remember is to disclose, disclose, disclose and have a good understanding of what you're doing before going out and starting!
