Fast forward a some years and now I'm making a good living doing that for a supplement company.

Exclusive representation enables a broker to market his properties to anyone he wants including you, but ties you into buying only from him.

And doing that would enable the listing agent to double dip on the commission, increasing the chance of the agent cooperating with me.

Very good supplemental reading to Hill's book.

If you are just starting off and are somewhat new you might want to consider "strong business credit" this will enable you to build your businesses credit to attract more traditional lenders.

I get lots of such supplemental property tax bills.  

I am interested, as of right now, in either single family or multifamily investing.Currently my basic real estate investing goals are meager, supplement my current salary with passive income from rentals.

Then, he/she will be able to help you construct a plan that will enable you to reach your short-term goals and reap the benefits needed for the proceeds and resources that your long-term goals will require.

I hope to acquire enough properties to supplement enough pay in rental income to leave my job to pursue flipping options or further rental possibilities.

Is there anything I can do right now or within a year to supplement my income to leave my job?
