RE Agent Investor

[DG H.]

When I first started investing (8 years), everyone said it wasn't worth the time nor effort to get your RE License. Too many drawbacks they said.
NOW...I'm seeing a lot of posts and many investors are getting their RE License. Why the change?
I'm thinking if money is short you can at least make a few buck on selling RE and if your buying and selling you get some perks on the commisions?
Any input or pointers yea or nay?
Thanks for answering.
