How do I find out who owns this property? Very cryptic Owner Name on Tax Recrods

[Chad Day]

I found a place on homesearch.com, which is an auction website.  The website seems shady at best and I don't want to go through them.  I would like to try negotiating directly with the owners, which looks like a bank or maybe some other company

I looked up the tax records and the listed owner is very cryptic:

 MASTR ADJ RATE MORTG TR
US BANK NAT ASSOC 209
7105 CORPORATE DR PTX-B-
PLANO TX 75024-0000

I did my best Googling but I can find who actually owns the place?  Is it US Bank?  is it Master Adj Rate Mortg Tr?

Do I even want to contact the owner?  Could there be a company that is handling this property that isn't HomeSearch.com?
