Using listing Broker to buy??? good or bad idea?

[Keong Kam]

Hello fellow investors:

I am looking into Commercial apartment deals (>12units) and got in touch with some local commercial brokers. Found one that seems to be doing a lot of transaction in the area and his company is broker/rehab/management pretty much all in house. The broker says he would be happy to send me new listings but asks that I don't bring in another broker to purchase, meaning that he doesn't want to share the commission with selling broker. So I would not be represented in this transaction. Is this a good idea? 

Has anyone done deals directly with listing broker?
