IAS 40 and IAS 2

Hello, I would like to ask a question regarding with IAS 40, IAS 2, IAS 16 AND IFRS 16. My question is, when a bank holds a collateral and gives credit to a customer, if the customer can not pay back the credit, how the bank will take that collateral into its accounts, as non-performing exposure? Will it be taken as an investment property or as a property held for sale? Moreover, if its an investment property, will it be depreciated, not depending on whether it is measured in cost model or fair value model? Furthermore, please consider that my question is related to commercial bank. Thank you.
