I know you are lying!!!

First of all, most states has a grace period after you sign for the loan that you can back out without any penalty. If you do not like the loan in anyway, you can just back out.

Secondly, most states require a disclosre to tell you how much your agent makes on your loan. Usually an agent makes slightly more money on 30 yr loan. Not sure why your agent want to change it to 3 or 5 yr, unless you are talking about 3/30 and 5/30. Since you have no idea what they are, I am sure you have made it up.
