Not likely… after all, how would google, or anyone for that matter, have access to a person’s bank accounts, life insurance policies, stocks/bonds, off-shore accounts, etc etc etc
When Google offers answers to questions, it’s a computer program that skims millions of web sites looking for what the computer thinks is probably a relevant answer to the question. It’s often wrong, and usually is just copying the opinion it found on some web site.
It’s not legal for people or companies to just do credit checks on anyone.
And even when someone (is coerced to) give(s) someone else permission to do a credit report on someone, such as when applying for a mortgage (as you suggested), credit checks only show what credit agencies know about a person (which is often incomplete and/or inaccurate), AND it shows debts but NOT assets.
