Well with a stroke of a pen some important things in the mortgage industry will stay the same for 2013–
Mortgage forgiveness debt relief extended thru 2013. For example, if your lender wrote off $50k in debt thru a short sale, you would’ve been taxed on the $50k just like it was income. Congress extended the code where as this is not treated as income.
Mortgage insurance deduction- retroactive for 2012 and extended thru 2013 for households with incomes up to $110,000.
