I have had video chats with my bank. The video part was not super important but nice given the magnitude of the transaction (house loan things). The more important part was the screensharing to sho the advisors calculations and other info.
Why do you need someone to show you the calculations? All of the important numbers including principal, fees, points, interest rate, and amortization schedule fit on a short PDF. You can verify the calculations yourself on a pocket calculator if you want, it's like grade school level arithmetic.
There are different sorts of loans that you can do in different ways. It certainly does not fit a short pdf (I am not in the US). So it’s nice to have someone walk you through that consequences of the different choices.
