How can I compete with a cash buyer investor?

[Brent Paul]

As the title says I am wondering how to compete with all the cash buyers in my area.  One of which owns over 90% of the apartment buildings as well as almost all commercial buildings in town.  He also frequents the city auctions and pays cash outbidding anyone that even tries.  Im guessing he gets off market deals too. I tried to start a conversation with the guy, but he is grade A jerk.  Hard to believe someone so arrogant can be so successful.

How do I compete with that?
