tenant's rights in a foreclosure situation

Question:

In Texas can a tenant purchase the home they live in directly from the lender if the landlord is in default of the mortgage and the lender is starting the foreclosure process? And if so, what are suggested procedures and actions to take if the landlord is unable to be located AT ALL?

I was thinking a possible “subject to” situation would be feasible with the filing of a grant deed; however, it requires the signature and, in turn, the presence of the landlord. Neither the tenants nor the management company can locate the landlord anywhere. And the management company doesn’t seem to be knowledgeable enough to assist in the matter.

Contact the bank and see if they will deal.
