Jay, Check your agreement and let your agent know about the home you found. Your agent can talk to this seller and might be able to get the seller to pay his/her commission. A good agent will easily be able to show how valuable their expertise is, and hopefully the seller will see the value in having your agent represent you as a client, and assist the seller as a customer to get everyone to the closing table. If your agent represents you, they will fight to get you the deal, at, or below, market value.
I am in Georgia where customarily, the seller pays the real estate commission. However, everything is negotiable. Hope that helps and Good Luck.
