Keep parents of the streets

My parents have had the local drycleaners for over 26 years, serving the community. Last year dad and mom were assaulted and both ended up in hospital. Due to covid they lost their biggest client making it impossible for them to pay all their accounts in full. They’ve managed to pay an amount each month, but has fallen way behind. Now they are in danger of loosing their house to settle their debt and will have no where to go with no funds left. The business has been in the market but no serious buyers has pitched so far. The business will be closing down 30 October 2021 permanently.
Dad will have to put the house in the market by the end of the month. Dad also has Parkinsons which makes this so much worse on his health.

Any help would be appreciated greatly
