I agree with Lance G here. I know Loopnet is a broker-driven site; so take the bias for what it's worth. However, dirt-brokers are 5%-10% of transaction price. However - they know what developers are real; which ones are active; what the market position of the property will be, what other stuff is selling for and listing for, etc.
You can make a mistake and get stuck in a contract and lose 10% pretty easily.
Maybe not in California; but in a lot of jurisdictions - real estate taxes cost 3%-4% of the property's value - so being on the market one year longer costs you most of the fee.
However - to answer your question if you want to do it yourself, or if you are a new broker - go to the ICSC Meeting with a package. As a member; you can get lists out the wazoo.
