There is probably no right or wrong. It depends on what you want to do. I put it in the same category of do you want to own your own lawyer or roofer or any number of other functions I am capable of doing; But is that where I want to spend my time?
@Derek Tellier can probably set you up with alerts that come to your inbox (along with wholesalers, and networking connections sending you off market deals). He also hosts an East TN RE meet up weekly where you can connect with lenders and flippers, etc to have other sources of leads in addition to the MLS.
I have done my own landscaping and ceiling repairs and spent time driving for dollars. And early on it is a great way to save some money and feel more involved and in control. I recently changed focus to networking and increasing the number of leads in the top of the funnel so I can spend my time evaluating and scale in a way I hope to.
Absolutely nothing wrong with becoming a RE agent. The question would be, are there others you can go ahead and connect with to achieve the same objective today and MLS leads begin appearing for you.
Hope that helps.
