Desperately need advice on Auction property / Mortgage

[Account Closed]

Hey everyone!

Thank you in advance for helping me get out of this tough spot. 



-Property was listed as a short sale prior to auction and under contract for 133k by someone else
-Bought a property at auction last week (HOA and tax liens) have until Friday to decide if I keep it

-Auction said I am responsible for all debts on property

-Selling agent said property has 250k mortgage even though its only worth 160
-Town doesn't have information on mortgage

-only mortgage I could find was started in 2006 (221k) and transferred banks in 2020

-Mortgage company says I'm not responsible for outstanding mortgage if there is one but couldn't find specific property 

I have spoken to a lawyer and they aren't sure what to do, so I'm coming here humbly asking for any ideas or input
