RE: Mortgaging the A home to pay bondsman.
The bondsman takes 10% and keeps it. The A's would have to come up with $50K cash to give away to the bondsman. If they didn't have $50K in cash, they would have to seek a loan from a bank. Banks want collateral. The house would be the first item to look at as collateral and it was already burdened with 2 prior mortgages. To lend the money to the A's, the bank would then be 3rd in line to collect on debts which already exceeded the value of the property. It would be throwing money down the toilet.
There are property bonds, but in order to post property as a bond, there must be an appraisal on the property and a search of the mortgage and conveyance records to determine the liens already in play. The equity in the property, after liens, would have to be worth 3 times the bond, or in this case, $150,000.
I don't think there was any choice available to them, despite KC's psycho reasoning. I don't believe there was $50K, much less $150K in equity in the property.
They could not have raised that money if they tried. Not everyone has $50K laying around in case their kid gets arrested for First Degree Murder, much less $150K. And not many people have $150K in equity in their home. KC is delusional and ignorant of the real world. She lives in the land where money grows on trees and babies sleep in car trunks.
