You need to look at your current rate vs. the new rate. Is it fixed or ARM?
If it's only been a couple of years, it might be a tough call. You likely already have good rate if you are fixed. Keep in mind that you need to cover the closing costs. Rolling them into the new mortgage affects the decision. You also have to be careful to compare your current loan percentage rate to the APR of the new loan. Those are two different numbers. The first is your "go forward" or sunk costs forward. The APR is the real cost of the refi, including fees and closing costs. If you have a current loan at 6%, the new loan is for 5%, but the new APR with closing is 5.99% then you need to sit tight.
This is a cut and paste from an accounting website regarding when to refinance. You need to pay particular attention to Rule 2, especially if you plan to roll any of the costs into the loan. If you dont' roll them in, there is also a "Time Value of Money" calculation you can do, but basically it means, "What if I invested this money instead". If you wouldn't invest it, then it's a moot point at the very low savings rates these days:
Rule 1: Don't Ignore Total Interest Costs
You really want to use refinancing as a way to reduce the total interest cost you pay. While that sounds simple in principle, it is sometimes difficult to do. The interest costs you pay are a function of the interest rate, the loan balance, and the loan term period.
When people refinance, they tend to focus solely on the loan interest rate. But they often don't pay as much attention to the loan term or the loan balance.
When you use refinancing-even refinancing at a lower interest rate-to increase your borrowing or to extend the time over which you borrow, you often aren't saving money.
Rule 2: Trade Expensive Money for Cheap Money
For refinancing to make economic sense, however, you do need to swap higher interest rate debt for lower interest rate debt. This calculation, however, is tricky. To make an apples-to-apples comparison, you must look at the annual percentage rate that will be charged on your new loan-this is the best measure of the new loan's interest rate cost-and then compare this to the loan interest rate on your old loan.
You don't want to compare interest rates on the two loans nor do you want to compare annual percentage rates on the two loans. Again, just to make this perfectly clear: You want to compare the loan interest rate on the old loan to the annual percentage rate on the new loan--these are two DIFFERENT numbers.
When the annual percentage rate on the new loan is lower than the loan interest rate on the old loan, then you are truly paying a lower interest rate.
Comparing annual percentage rates with loan interest rates seems confusing at first. But note that you would pay only interest on your old or current loan, so that's all you need to look at in terms of its costs. With a new loan, however, you would pay both interest and any origination or closing cost fees. The annual percentage rate wraps the interest rate charges and setup charges, origination charges, and closing cost fees into one interest rate-like number.
Rule 3: Don't Lengthen the Repayment Period
Be careful that you don't extend the length of time you borrow by continually refinancing. For example, one common rule of thumb states that every time interest rates drop by two percentage points, you should refinance your mortgage. However, there have been times in recent history when following this rule would have had you refinancing your mortgage every few years. This could mean that you would never get your mortgage paid off. If you refinanced every few years, you would suddenly find yourself still 30 years away from having your mortgage paid.
First, I just want to point out that I'm not a financial adviser. I used to work for a huge bank and did mortgages for a living until the whole mortgage crisis thing and then my entire department along with a lot of other people were laid off. I still have my mortgage calculator though.I am currently locked in at 5.50 thru Wells Fargo. I refinanced about 3 years back and went from a 30 year mortgage to a 15 year. I saw this morning that the average rate was 4.45% and supposed to be rising soon. Thanks for yall's help and advice.
