If there is a big difference between the initial interest rate and the APR listed in the ad, it may mean that there are high fees associated with the loan.
The majority of your mortgage payment goes toward paying interest. To save an astounding amount of money over the long term, choose a mortgage loan with a lower rate and a shorter payback term. A 15-year mortgage may be just what the financial planner ordered. This type of loan carries a larger monthly payment; but if your budget can withstand the jolt, you can save big bucks over the long haul.
You can ask for a copy of your settlement cost papers (the HUD-1 form) one day in advance of your loan closing. This will give you a chance to review the documents and verify the terms.
If you do not plan on staying in the house very long, refinancing may not be in your best interests.
