Along those lines, notify your mortgage company immediately. They will try to help. No mortgagor wants you to lose your house: they're in the business of lending money, not of managing empty houses. They will most likely let you miss payments for a month or two without incurring penalties. If you're still unemployed after that, you can discuss mortgage modifications that will reduce the amount you have to pay monthly.

Especially with all the people who lost jobs due to COVID, they have become very accustomed to having to deal with this recently.
