I'm not sure about the US but I think you are not kicked out from the first day / first month. For auto-leases, the bank might wait a couple months max; but for houses it's usually negotiable with the bank. For the bank, it's a lengthy process that requires selling the house to recover their capital. It's not something they want to go through unless the economy is super strong and they can sell the house really fast.
Right now, it might be hard to 1. sell the house fast and 2. sell the house at a good enough price to recover their capital. If you are only a few months away from a job you should be able to negotiate but my guess is that some (many?) people shouldn't have gotten into these loans in the first place.
