Short-term mortgages offer lower interest rates than long-term mortgages. You save money by the lower interest rates and shorter payment period. The trade off is a larger monthly payment, but this option can save you thousands.
Use a mortgage broker. A mortgage broker will show you mortgage products from different banks and mortgage providers. Pick a mortgage broker carefully. If the broker works directly for a company that offers financial products, make sure he shows you clearly why one of these products is better. Mortgage brokers also get a commission on their sales. Find out what the broker's services include and if he charges any fees. Many brokers do not charge fees beyond their commission. Also check the broker's credentials.
Get your interest rate and closing costs in writing as soon as you decide on a lender to work with. Get your lender to give you a commitment in advance of all of the costs that will be involved with your loan. Find out if the refinance loan you are getting has a pre-payment penalty as well. Sometimes lenders will leave out important information like this, if they think it might scare you away from refinancing with them.
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.
