Once paid at auction, is there a way out ?

I won and paid for a trustee sale yesterday, but I now had second thought, just wondering, is there a way for me to get out of the deal and get my cashier check back ? I’d imagine not possible, but just asking.

I don’t know the laws in Texas, but probably not, unless you have reason to believe the sale was made in error. If you want to try, I’d recommend calling the trustee right away.
