A colleague of mine several years ago got an offer in the mail, saying she could refinance her home and thereby lower her payments and pay her house off sooner.
So she called them and signed the paperwork.
Then she asked me why it was that her payments were higher than before, and she noticed that she would have to make 360 of them.
Bring me the first mortgage papers and the new ones, and I will perhaps be able to tell you, I said. What they tell you is meaningless, only what you signed counts.
Of course, she didn't. They told her one thing and the terms on the papers were entirely different, so she screwed herself.
A lot of people just do not understand this. Like the ones that say that my investing in mutual funds is the same thing as their buying lottery tickets, another form of gambling.
