The post does not use a valid definition if insolvent. My recent posts contains valid definitions, but this is constantly ignored.
A third graded would know that his (or her) parents owe $150,000 on the house and that they do not have $150,000 in the bank to pay off this mortgage (ie liability), but this third grader would also know that the parents make a mortgage payment (ie bill or installment payment) every month. The family is not insolvent or bankrupt as long as they make the payment every month.
