Personal bank asking about mortgage

My gf and i bought a house this year, my gf rang our personal bank who refused us a mortgage to tell them we changed address, they wanted to know who if we bought the house, who we got the mortgage from and how much we paid for the house??? Gf told them to get lost as they wouldn’t even accept our mortgage application.

Anyone know why they would ask those questions?

Marketing mostly, they might want to sell you life or house insurance.

Probably reckoned that if you would take a mortgage product in 2010 they could sell you anything…and no I am not being facetious, merely scientific.

Fixed that
