I am not sure what to do. 3 years ago we used our second home as collateral to open a new business. The amount borrowed was 400K. To date we have paid 200K in interest. The business is failing and we are one payment behind with the lender. The monthly payment is 7K. The lender has sent a letter threatening to expediate the loan. We are current on our primary mortgage company. What are my options? What happens if I cannot make the payment? Thanks.
