How long does it typically take for the payments on an interest only loan or adjustable rate loans to increase? Many homes that are on the market were bought in 2005, so is it safe to assume that it takes 3 years for the payments to increase? Does that mean that their is still a wave of selling to come from the people that bought in 2006? when did the adjustable rate/ or interest only mortgage mess stop? was it 2006? so can we calculate 2009 to be an end to the wave of houses to come on the market?
