A mortgage refinance is just that - a move to pay-off your mortgage by taking out a new loan on your home. Refinancing a mortgage therefore simply means replacing an old mortgage with a new one.

Should You or Shouldn't You?

There's no simple yes or no answer to this question. It would be better to leave it at it depends on your situation, priorities and preferences. Generally, however, you should refinance if you can save money by so doing. This can come about in two ways.

Lower interest costs: First, if you are refinancing to a loan with a lower interest rate than your current mortgage, then you can conceivably save on interest rate payments and therefore be able to make more payments towards the principal, increase your equity at a faster rate and pay your loan much earlier than you expected to do so.

For example, if the current annual rate of interest of your mortgage is 8.25%, your monthly interest rate is around 0.6781%. If your current mortgage balance is $80,000 and you have an interest-only mortgage, then you're expected to make an interest payment of around $542.48 monthly.

You ...
... will save money on interest payments if you manage to refinance to a lower rate. If you manage to obtain a mortgage refinance loan with an interest rate of only 6%, for example, your monthly interest charge will become only $394.52. This is a savings of around $147.96 every month on an interest-only payment scheme.

Lower future interest costs: Second, if you have a mortgage with an increasing variable rate of interest, then you can gain savings on future interest rate payments through refinancing your mortgage with a fixed-rate loan program. By doing this, you'll be able to keep your mortgage interest rate - and thereby your interest costs - at a constant level.

For example, if you have a mortgage whose interest rate is currently 6.5% and a balance of $80,000 (as in the previous example), monthly interest payments would be around $427.40. However, if your loan's index rate (the rate on which your actual interest rate is based) increases by one point and becomes 7.5% the next year, then your monthly interest charges on the same balance would be $493.15. If the year after that, your interest rate increases by another point, your interest rate will become 8.5%. Assuming that you still haven't made any payments towards your principal, your monthly payments will become $558.90.

In three years, therefore, your interest rate payments will change from 427.40 to $493.15 then to $558.90. Assuming that each particular interest rate sticks around for a year, your interest rate payments in three years will amount to $17,753.42.

On the other hand, if you changed to a fixed rate of interest now, you can save yourself money on future interest payments. For instance, you can replace your 6% adjustable rate mortgage with a 7% fixed-rate mortgage refinance. This will actually make your current interest rate payments greater at $460.27 but this will lead to savings of around $32.88 next year and $98.63 the following year. In this fixed-rate loan, your interest payments in three years amount to only $16,569.86 - yielding a total savings of $1,183.56 in interest rate payments.

Of course, current and future savings aren't the only considerations when deciding to refinance. You should also weigh your savings with the costs of refinancing. When you refinance, you will also pay various loan processing fees as well as the origination fee. Compute the costs of a mortgage refinance and compare it with your projected savings. Refinance only if your savings will be greater than the costs.
