What if the Bank refuses to accept my property keys back?
Not the end of the story:
Monitor and oppose if:
(a) Your mortgage deeds have abusive clauses which can stop or void the repossession: anticipated maturity clause, lack of communication of the sale of the mortgage debt to a vulture fund, floor clause, IRPH…
(b) The enforcement procedure is being according to Law
(c) Value given to the property for auction is correct, mainly if Banks are respecting the minimums established by Law as a barrier for them not to bargain with mortgage debtor rights.
In most cases, your pending debt is below the value a Bank can repossess the property for, so it is for mutual benefit that an agreement is signed. Offer a prospective buyer—even for a very low price—and possibilities of a quick settlement will increase significantly.
