I've never worked in an office, so when I was asked to speak at an agency a few years ago, it was kind of cool. There's an energy around you of 'things getting done' that doesn't really exist in your home office.
If you did go that route I think it would be very easy to position yourself as the go-to guy for whatever type of deal you want. LP, sub2, wholesale etc. just talk to everyone and make sure they know to contact you when they come across a seller that meets certain criteria. As a fellow agent if you make it clear that you are NOT competing against them, they'd probably warm up to working with you a lot faster than if you approached them from 'outside' as an investor.
Of course this all depends on how understanding your broker is!
I personally decided against getting my license because of the bureaucracy.
