Honestly, they are likely scumbags.
If they got a new car, then I 99% guarantee they pocketed the $700k with a family member or close friend (incentivized by a small %age of the pocketed money), and have not been paying their bills on the business for some time.
I know this because this is how most folks in Cali handled bankruptcy and defaulting on homes. They'd post on Craigslist 18-24 months before default, but after they'd decided they'd stop paying the mortgage.
Then, they'd get 3-4 cash renters for said house, and collect $3-4k a month every month for the next 2 years, which they'd keep with a friend, or in a checking account they'd then liquidate right at the end.
So at the end of the day, they'd go bankrupt, but have $50-100k+ cash-free hidden away that the govt never knew about.
