closing a deal on rental

[Danick St jean]

So I made an offer on a rental that pm says would be a good deal. The seller returns and counter offer it. May sound stupid and I told my realtor I accepted it but want seller yo pay closing cost. Is it typical to have the Buyer pay closing cost. What is the average cost for closing on 8500.00 purchase in memphis? Should I print it out and check accepted and email back or van realtor just submit it for me?
