Typically, business loans are secured against the assets of the company as well as the personal liability of partners (even if it's a limited liability company). But if the company borrows tens of millions of dollars, the home (which itself will already be financed, so realistically only the home equity) of the founder/owner of the company is small compared to the company's financing needs. Banks will prefer that the management 'have skin in the game', but from a purely recovery perspective ('loss given default', to the bank) it's negligible. So, non-recourse loans will be typical for large corporations. Unless they're owned by a billionaire. This is why you and your spouse have a prenuptial agreement that keeps your finances separate, and the house out of reach of your creditors.
