"Got it" is a really weird one too, "Ok" had a hint that you are in approval of what you're seeing. "Got it" is more of a message of "we know you probably don't care or even detest this but you have to tell us you are at least aware of our latest thing".
It is underhanded in the language and has a bit of admission that they know you really just want the modal to just go away.
One of the major things that is different is that loans are a lot different from what kicked off the '08 crash. We didn't see a flood of interest only, 5/1ARM or other exotic lending setups. Yes, there are some out there but they aren't as large of a slice of the market. Banks have to keep more capital than when WaMU crashed and we even saw some larger regional banks fail this year with only a rather minor impact outside of SV angel investor lending.
This isn't going to be like '08, There would need to be a major situation to cause house pricing to fall like a depression level downturn or industrial level of house construction destabilizes the market.
