They have had other LLCs and corporations with many of the same players.

Areas like that are often, though not always, typically dominated by agents, so it can be harder to find off market deals in such areas.If there is an agent doing the majority of business in that neighborhood, you may want to consider contacting them (Or getting your own agent and having them contact them) to inquire about upcoming listing or possible pocket listings, and buying the property before it hits the MLS.

Go to REIAs Meetup groups, real estate auctions (generally there are real players with money at auctions). 

@Jean Norton   Well that return will take care of one lunch   LOL... if you have mass and scale its a nice play I have been to a few of the sales, I was used to CA tax deed and the tax cert sales were wild and the good ole boy  major players defiantly controlled the room and cherry picked the certs...

The stick wood frame I'm competing with dominates and has so much experience I can not compete with their chopped up roofs, dormers, etc, yet.

I would pay a seasoned player at auctions to do the research for you.

I’m sure you have already done this but have you evaluated the marketplace to see who the current players are?  

Not all of them are home runs, but every time a baseball player steps to the mound he doesn't hit a a home run.

Lima One and LendingOne are two big players in that space.

and or they will work with known larger players of which you have many.
