Recently filled in Consumer Sjopping Survey and have now been found by National Home Loans. Apparrentley shopping surveys are sent out by either Experian or Equifax and then used to trace people.(posted 8267 days ago)Can anyone expain why Interest is added to the mortgage balance after repossession and after the property has been sold. National Home Loans have done this leaving me with a shortfall of 32500.00. If the interest has not been added they would owe me 10000.00!!!
