To find online lic classes call the president of the local REIA they will provide some choices.

I bought out my sister's ownership and renovated the whole property heavily while renting it out by the room averaging $400-$2000/month depending on occupancy rate (later stopped 'multi-family' rental model since against HOA rules and got caught by our president when the number of tenants got out of hand + visitors on weekends etc).

What are the pros and cons as an investor, in choosing to work with a real estate broker over a real estate agent or vice versa? 

Hello Eduardo, Yes I agree with you , now you do know since the new  buyer will own a majority of the condos with the purchase of 9 units and they will take over as president, of hoa,  they will control the Hoa as well by owning the 9 units.

You could also rent it for someone's car (some people have one more that needs shelter than they have garages) or some businesses trucks (some towns have ordinances about parking them in residential areas--so they need a place to park--they put their car in during work vehicle use and then swap back).Figure out their alternate options for these things and then find out how much those would cost, and what they offer that you lack and vice-versa.  

I founded the Mid-South REIA about 5 years ago and I am the President of the organization.

I built relationships with REO contacts, bank presidents, contractors, agents, builders, and investors and started to build portfolios similar to a REIT as I searched for my own place to call home.

Now I've seen a couple posts where others have mentioned that they are not your typical RE agent (driving buyers around, and bothering family & friends) and use their license to better monetize leads for flipping and wholesaling.So here's my question, in what ways can i actually use a RE license to make me a better investor and vice versa? 

The doctorate might help you if you want to advance in leadership in your community college- like become a dean or administrator or vice president of ???. 

His price, your terms (or vice versa) usually works well.Then refinance it using conventional money.
