FL - Property Auction / Existing Mortgage

[Jorge Medina]

Grand Rising Everyone! 

I was wondering, if I win a property at auction with an existing mortgage, what happens with that mortgage? 

Am I held responsible? Do I have to negotiate with the bank? (considering I may have some leverage since they weren't going to get paid anyway) 

What options do I have? 

Any and all answers would be highly appreciated. Thanks!
