I think there is huge value in going this route, for the reasons mentioned above. Having that MLS access and being able to be the FIRST to write a strong offer, ability to contact and ultimately form relationships with the various listing agents...huge value.
And being an investor yourself, there is additional perceived value when marketing yourself to other investors who don't have their license. You understand the 1% rule, 2% rule, true cash flow (not just rent less mortgage), etc.
How many times have I had an agent tell me "You'll be cash-flowing great!", hahaaaaaa...
For the small cost to obtain and hang your license, I think it's a great investment.
