"Buyer Services" realtors are paid by the seller as a percentage of the sale price of the home. For example, a standard commission on a home sale is 7%, split between the buyer's realtor and the seller's realtor. So if you buy a home for $100,000 the seller pays $3,500 to his realtor and $3,500 to your realtor and walks away with $93,000. So while 'you' didn't directly pay anything if you bought the house without a realtor for $96,500 the seller's realtor still gets his $3,500 and the seller gets $93,000. Don't be fooled by stories buyers realtors will try to convince you don't pay for them. Especially consider this - if the seller pays they buyers realtor do they work for the buyer or the person who actually pays for them?
