Will not affect your mortgage. But for the bank staff, if you don't help him complete other business indicators such as credit cards, he can delay the time, the approval time is long, and the loan time is delayed. See how you choose. Credit cards and the like don't cost you money. I think it's acceptable. If you are required to buy insurance for financial management, you should think carefully. Of course, if you have plenty of mortgage time, just drag it out for three to five months and ignore him completely.
