Buying a Property without a Buyer's Agent

[Christopher Hui]

I have the opportunity to buy a property for a great price, new construction. I have been in contact with the builder (a real estate agent and his son) since before the construction even started and since I lived right next to the new property, he would give me first crack at the offer. We agreed on $430k, but when I brought up my real estate agents, he said that it wouldn't be necessary and that it would be a deal between his son (the actual builder and owner of the property) and I.

Has anyone purchased a property without a buyer's agent?

Do I really need a real estate agent? Should I insist on my real estate agent? Will he increase the price to compensate for the commission?

Thanks for the help!
