That is easy to do. You may want to consider just keeping the Oil and Gas rights as it will make it easier to sell.
The process is easy, just make sure the deed states the sale is for Surface Only and Excludes the Oil, Gas & Minerals.
I have seen errors made when people have used a title company and not an attorney, leaving the seller little recourse. Please have your Purchase Sale Agreement and Deed reviewed by an Attorney to insure everything is copesthetic.
Thanks for the good advise. will check with g/o Attorney for the correct wording in the Deed. Thanks again Don
