I know that mortgage is that monthly bill you have to pay to keep a house. Every time you have a house a mortgage is what you have to deal with so if you got that good job then you are strapped. I remember I was watching a show on tv I think it was "Househunters" and there was one homeowner who did not move out of his house because he did not want a double mortgage. I want to know what are some tips that people can use to avoid a double mortgage. It is a important thing that I think that people should know before going off to buy his or her home.
