Im not an expert, but if home prices have dropped on average 30% nationwide that would mean almost all the HELOCS, 2nds, pay option arms,are basically secured by nothing. Of course the foreclosures hurt the financial companies and maybe we;ve seen the bulk of those write downs, but i know from experience that the majority of all helocs and 2nds are secured by the last 75%-100% of home value... and there are A LOT of them. Have financial companies really already written down all of this now unsecured debt?
