@Garrett O'brien  Hope you'er ready for a great ride to the top by using all the free tools and more.

If anything, the lessons here is 1) make sure your partnerships meet the desirable credit score, 2) make sure you meet requirements for B2R Financing, but still a great tool to use when refinancing your property. 

Although most successful workers with great reputations most likely don't need craigslist as a marketing tool, but you never know.  

Another thing it gives you is credibility and a certain level of know how in addition to realtor tools and connections.On the opposite side, one thing that may be to your detriment is that when you sell your properties you HAVE to advertise that you are selling as an Owner/Broker.

If someone stopped over, I'd politely talk to them but mass marketing doesn't work for anyone who has any basic understanding.   

Take advantage of the wisdom from the members, and the educational tools on this site.IMO, you are in one of the best neighborhoods to invest in around SoCal.

@Jordan Finkelman & @Mantas Kudrinas ,A powerful tool to identify properties are the Miami-Dade and Broward County Zoning Websites.  

The good few were really good at understanding the numbers an investor needs to make the deal work and can help explain (negotiate) that in a polite way to an emotional seller.

Google keyword tool.

I like your idea the best.We recently lost a good number of tools to a thief.
