I've now gotten a safe method for myself to sell horses near the spawn area. First successful trade went to LayToRest and Mister_Tulip, so shout out to them. If anyone is interested post here, pm me, or message me in game.
P.S. Don't try to buy horses from baron_ultimax or his buddy colzaidikari, they tried to kill me when I tried to buy off of them. Thanks to pippenger and Esquerdo their base is in ruins and their horses are ours :)
