I will provide useful information along the way, but getting subscribers is the number one goal, and to that end, most of the talking heads are going to make investing sound FAR more sexy and lucrative than it really is.  

It sounds like you would make them available at an additional cost?

It can take a year or more to complete an ADU.

It sounds like your current property manager may not be marketing the rental effectively, and the fact that it's listed incorrectly as an apartment instead of a duplex could be turning off potential renters.

Quote from @Jennifer Fernéz: It sounds like you are embarassed to charge the $50 fee.

It always sounds attractive. $300 a month for leads?

I would also advise doing your own inspection of the property to make sure that everything that they say is being done is actually completed and to code and that there shouldn't be any surprise maintenance costs at the beginning.  

Don't be discouraged by the one you just attended, which doesn't sound like a REIA at all.

Even with a completed sale often times you might need/want to pay a lawyer to do a quiet title action to quell any possibly attempts to reverse the sale by an interested party.

If you decide to move forward, complete state-required coursework, pass the exam, and find a sponsoring broker.
