How is the realtor fee, and other closing costs, adjusted on very cheap homes?

Hi, I'm trying to figure out what to expect in terms of closing costs as a percentage of purchase price for cash purchases on homes priced under $30,000.

I know I'll save on credit report fees, loan origination, and title insurance.

How about the realtor fee? For such a cheap home bought off the MLS, should I expect to pay more than 3/6%?
