When it comes to getting or refinancing a mortgage, little things can turn into big bucks quickly.

For example, small differences in interest rates can mean thousands (even tens of thousands) of dollars in additional interest charges over the life of the loan. Or, a slight difference in rates among different loans can signal fees that can mean hundreds or thousands of dollars in hidden costs. “I’ve literally seen differences of \$5,000 in fees (between various loans),” says David Ginsburg, president of LoanTech.com.

When you are quoted a mortgage rate online or verbally, the lender must disclose an annual percentage rate (APR). There is usually a difference between the APR and the interest rate, because the former takes into account interest plus additional costs. As the Consumer Financial Protection Bureau explains:

An annual percentage rate is a broader measure of the cost to you of borrowing money. The APR reflects not only the interest rate but also the points, mortgage broker fees, and other charges that you have to pay to get the loan. For that reason, your APR is usually higher than your interest rate.

Comparing interest rates, APRs and fees can be confusing, and it can be tough to choose among various loans. And sometimes what may seem like a better deal may not be, depending on your individual situation.

Let’s say you are getting or refinancing a \$250,000 mortgage loan for 30 years. You are quoted three APRs:

• 3.931% APR (interest rate 3.875%)
• 4.078% APR (interest rate 4%)
• 4.157% APR (interest rate 4.125%)

If you’re like most of us, you’ll probably assume the lowest APR is the no-brainer right?

Not so fast. In this example, the lower APR loan carries higher fees. Here’s how the fees shake out when these quotes are analyzed using Loantech’s My Loan Cost Calculator, which compares and evaluates different loan options based on the consumer’s goals (minimize fees, payments, payoffs, or total interest and fees):

• 3.931% = fees of \$1,694 (monthly payment: \$1,175.59)
• 4.078% = fees of \$2,338 (monthly payment: \$1,193.54)
• 4.157% = fees of \$956 (monthly payment \$1,211.62)

In this example, the loan with the highest APR has the lowest fees. The lower APR is still the cheapest loan overall, but when you’re comparing mortgage rates, you’ll want to also take into account how long you plan to keep the loan. Paying higher fees on a loan with a lower APR may make sense when you plan to keep a loan long enough to break even on the fees.

## 5 Fees to Look For

What kind of fees are we talking about here? Fees that may affect the APR include:

• Loan origination fee
• Lender fee (formerly known as discount fee)
• Lock fee or commitment fee
• Underwriting fee
• Processing fee

Some fees can be negotiated down or even away, but you won’t know if you don’t ask. And that means understanding how much you are being charged in fees in the first place.

Of course, as with any loan the best deals typically go to consumers with good credit scores. The differences are especially stark in the case of mortgages, where the interest over 10, 20 or 30 years can really add up. For example, in the options above, the total cost (interest and fees) of these loans after 10 years is:

• 3.931% = \$88,889
• 4.078% = \$92,523
• 4.157% = \$94,139

Securing the lower APR loan saves a borrower more than \$5,000 10 years into the loan in this example.

If you’re going to get a mortgage the smart thing to do is to understand where you stand with your credit (you can get two free credit scores at Credit.com updated every 14 days), compare the cost of fees along with APRs when getting rate quotes, and understand the lifetime cost of debt. Together, these steps can help you make a smarter decision when you borrow.

Please note that our comments are moderated, so it may take a little time before you see them on the page. Thanks for your patience.

Credit.com receives compensation for the financial products and services advertised on this site if our users apply for and sign up for any of them.

Thanks for checking out Credit.com. We hope you find the site and the journalism we produce useful. We wanted to take some time to tell you a bit about ourselves.

Our People

The Credit.com editorial team is staffed by a team of editors and reporters, each with many years of financial reporting experience. We’ve worked for places like the New York Times, American Banker, Frontline, TheStreet.com, Business Insider, ABC News, NBC News, CNBC and many others. We also employ a few freelancers and more than 50 contributors (these are typically subject matter experts from the worlds of finance, academia, politics, business and elsewhere).

Our Reporting

We take great pains to ensure that the articles, video and graphics you see on Credit.com are thoroughly reported and fact-checked. Each story is read by two separate editors, and we adhere to the highest editorial standards. We’re not perfect, however, and if you see something that you think is wrong, please email us at editorial team [at] credit [dot] com,

The Credit.com editorial team is committed to providing our readers and viewers with sound, well-reported and understandable information designed to inform and empower. We won’t tell you what to do. We will, however, do our best to explain the consequences of various actions, thereby arming you with the information you need to make decisions that are in your best interests. We also write about things relating to money and finance we think are interesting and want to share.

In addition to appearing on Credit.com, our articles are syndicated to dozens of other news sites. We have more than 100 partners, including MSN, ABC News, CBS News, Yahoo, Marketwatch, Scripps, Money Magazine and many others. This network operates similarly to the Associated Press or Reuters, except we focus almost exclusively on issues relating to personal finance. These are not advertorial or paid placements, rather we provide these articles to our partners in most cases for free. These relationships create more awareness of Credit.com in general and they result in more traffic to us as well.

Credit.com’s journalism is largely supported by an e-commerce business model. Rather than rely on revenue from display ad impressions, Credit.com maintains a financial marketplace separate from its editorial pages. When someone navigates to those pages, and applies for a credit card, for example, Credit.com will get paid what is essentially a finder’s fee if that person ends up getting the card. That doesn’t mean, however, that our editorial decisions are informed by the products available in our marketplace. The editorial team chooses what to write about and how to write about it independently of the decisions and priorities of the business side of the company. In fact, we maintain a strict and important firewall between the editorial and business departments. Our mission as journalists is to serve the reader, not the advertiser. In that sense, we are no different from any other news organization that is supported by ad revenue.

Visitors to Credit.com are also able to register for a free Credit.com account, which gives them access to a tool called The Credit Report Card. This tool provides users with two free credit scores and a breakdown of the information in their Experian credit report, updated twice monthly. Again, this tool is entirely free, and we mention that frequently in our articles, because we think that it’s a good thing for users to have access to data like this. Separate from its educational value, there is also a business angle to the Credit Report Card. Registered users can be matched with products and services for which they are most likely to qualify. In other words, if you register and you find that your credit is less than stellar, Credit.com won’t recommend a high-end platinum credit card that requires an excellent credit score You’d likely get rejected, and that’s no good for you or Credit.com. You’d be no closer to getting a product you need, there’d be a wasted inquiry on your credit report, and Credit.com wouldn’t get paid. These are essentially what are commonly referred to as "targeted ads" in the world of the Internet. Despite all of this, however, even if you never apply for any product, the Credit Report Card will remain free, and none of this will impact how the editorial team reports on credit and credit scores.
