So you don't get on the net or hire a proxy and it sells at the sale to another tax buyer... 

PLENTY of potential, and just starting to uptick in price and demand by buyers. 

They also don't do "pre-approval" letters and do loan guarantees so you are the same as a cash buyer.

I have a buyer approved with 130k FHA loan and about 20-30k in cash.

Seller's market for MLS deals, not a buyers. 

Being around buyers/sellers etc and just that environment.

This happens a lot in Southern California and Im trying to understand the dynamics.Broker originally represents seller, and ends up representing both buyer and seller,Broker finds a buyer, but broker is only getting %2 commission, would it be reasonable to also represent the buyer.

So if you have an LLC and are putting deals under contract with your LLC then your signature at the bottom will be something along the lines of "David Todd managing member" but within your contract you will be using your LLC's name as "buyer".My LLC has a business checking/savings account that I deposit my investing checks into (since all my deals I use my LLC to close with)

Do you have any recommendations on an agency that would sponsor me on the licensee knowing that I'm not going to be actively working as a buyers/seller's agent other than on a limited part-time basis?

All in one software that can locate cash buyers, distressed properties; the liens and notes on them and everything else needed to know.
