How long is too long to live at home after graduation?  It depends on whom you ask.

According to a survey by Coldwell Banker Real Estate, younger parents (ages 18 to 34) think living at home with mom and dad for up to six years after school is fine.

Parents 55 and older think three years is okay - four is pushing it.

But some parents, who fear an empty nest, were found to be more tolerant of boomerang kids.

Overall, nearly one in four (24%) think kids should be allowed to stay as long as they want.
