tracking down a bank owned property

[Greg Condon]

I have found a foreclosed home in my area but can not find out what bank or mortgage company owns it.  It has been locked up by a service that secures foreclosed homes. I went to town tax records and found the old owner who was foreclosed on.  the bank has owned it for over a year but I am having trouble finding out what bank.  Please advise,  Thank you,
