Here is a great example of how a sudden thunderstorm (with hail) can cause a total loss and how GAP can help prevent a major financial loss.
To add insult to injury, the primary insurance carrier used CCC to do a Local Market Valuation Report, using their typical huge deductions to lowball the Actual Cash Value settlement. The original LTV% was only 79.50% and the GAP claim was still $5,497.71! Just another example of why you should at least be discussing GAP with every loan.
