The traditional answer to the question "When is the best time to refinance?" is when interest rates fall 2 percent below your current mortgage interest rate. However, in recent years some experts have argued that refinancing may be appropriate with a smaller point spread. Some weight is often given to the length of time the owner anticipates holding on to the property. If the owner expects to keep the property for at least three or four years, then refinancing may be worthwhile. While refinancing can involve upfront costs, in many cases it is possible to roll the costs of the refinancing into the new note and still reduce the amount of the monthly payment
Discount points allow you to lower your interest rate. They are essentially prepaid interest, with each point equaling 1% of the total loan amount. Generally, for each point paid on a 30-year mortgage, the interest rate is reduced by 1/8 (or.125) of a percentage point. When shopping for loans, ask lenders for an interest rate with 0 points and then see how much the rate decreases with each point paid. Discount points are smart if you plan to stay in a home for some time since they can lower the monthly loan payment. Points are tax deductible when you purchase a home and you may be able to negotiate for the seller to pay for some of them.
