Many homeowners are facing upside down mortgage today. This means that their mortgage balance is higher than the value of their property. If you are an investor, this does not make sense. Many are blaming this on the decline of the values of the properties. There are also those who dub interest only loans and subprime loans as the major culprits. Well, who would not? Such loans left little for the payment of the principal amounts. In addition to that, the interest rate is high.
