This doesn't even account for additional liens etc. that can be added on after the second is bought.Since the first is still on the property many liens can be attached.Contrary to popular belief the the 1st and the second are 2 different loans with different payments and numbers.The asset manager on one loan has the duty to limit losses for that one loan while the other AM handles the first.So the first and second positions have different goals in mind.Many seconds are worthless.Example had a customer call the other day.4 bed 3 bath bought in 2006 for 160,000.1st 130,000 second 30,000.Now properties are selling foreclosure for 89,000 REO.
