Yeah you are definitely not in one of the friendliest gun states. Don't know your state laws but there may be a law against selling at estate/garage sales. Most auction houses don't have an FFL which is why they can't sell firearms. I know a lot of dealers will get contacted to buy a lot of guns from estates where the beneficiaries don't want anything to do with them.
