@Kris B. If you purchase a property that you intend to flip and working with a realtor the seller pays the buyers agent commission. You as the buyer don't pay the agent. Unless you agreed in advance with the agent to pay them a commission if they help you find an "off market" property where the seller typically does not pay any buyers agent commission. But when you go to sell your flip after the remodel then you negotiate the commission with an agent what you will pay them at closing, as well as, to any buyers agent that bring fort a buyer. This is executed thru an Exclusive Right to Sell agreement you and the agent sign before you list the property for sale.
According to the National Association of Realtors (NAR) last year For Sale By Owners (FSBO) properties in the US sold for 26% less than those listed with a licensed agent. Good article from NAR on advantages of listing with an agent versus FSBO https://www.nar.realtor/magazine/real-estate-news/sales-mark...
I have worked with many clients in the DFW market on helping other investors acquire and seller their flips. I would be happy to help you too. I help clients avoid the mistakes both my clients and I have made on our past flips. Hope this helps.
