Buying without a Realtor---Saving Money?

[Nate Rohlf]

Hello,

I am in the process of making my second purchase in Sioux Falls SD.  Im not using a realtor as I feel I know what I want and I know the neighborhoods.  

I have thought of using an attorney to draw up the purchase agreement but I want to entice the seller with the opportunity to save money as he will not have to pay for the commission on my side (if I had a realtor).  That way it looks like he is saving 3%, (6% total/split between the buyer/seller realtors).    Am I correct on this one?

How do I write this or word it on the purchase agreement?  

Also I thought I read on BP that the seller agrees to pay a 6% commission and then they split it up between the buyer and sellers realtors?  Would I just be giving the sellers agent the full 6%?
