This is a short article but I wanted to capture this piece of data... This article How much longer will mortgage rates stay low? quotes a forecast on mortgage rates for 2013 and 2014.
They say :
..., we checked the mortgage interest rate projections made by the Mortgage Bankers Association (MBA), the national organization representing the real estate finance industry....
According to the MBA, by the end of 2013, the interest rate on a 30-year fixed mortgage will be at 4.4 percent. And by the end of 2014, they see the rate at 4.6 percent.
Of course this is just their 'guess' really. I don't know how much faith you can put in it.
