Refinancing mistakes can cost you a lot of money. You can avoid these mistakes by being a smart loan shopper. Don't gamble on future rates, but make your refinance decision on what is available today. Use accessible information by researching rates and fees from a number of companies to find the best deals. And make sure you compare interest costs, not just rates.

1. Waiting For Lower Rates

Mortgage rates are notoriously unpredictable. No one can guarantee rates will drop or rise in the future – they are just guessing. So instead of listing to financial forecasts, invest some time in looking for a low rate lender.

With the internet, you can quickly compare rates and fees that are posted on lender sites. You can even get a free loan quote based on your unique credit history and financial resources. Then look at your potential savings to see if refinancing is worth it.

2. Not Checking Rates

Even though the news and financial analysts talk of one mortgage rate, in reality there are hundreds. Each mortgage company has their own criteria for determining rates. That is why posted rates on websites vary.

Lenders also have different standards for evaluating credit. So while general posted rates can help you narrow your refi lender search, you still need to ask for a loan estimate.

3. Assuming Lower Rates Will Save You Money

Amortization makes the refinancing question tricky. With the majority of your interest paid at the beginning of the loan period, refinancing usually only makes sense in the first couple of years.

Of course there are exceptions. For instance, if you refinance for a shorter period with significantly lower rates, you can save a bundle. You may also decide to refinance in order to cash out part of your equity at a lower rate. Immediate lower payments may also make a refinance worthwhile

Before signing for a refinance, make sure you understand how much savings you will see. Don't just compare interest rates. Also look at interest payments left on your current mortgage and compare it to the refi mortgage.

With a little bit of time and the right information, you will save yourself thousands of dollars
