Home > Mortgages > 3 Things Homebuyers Need to Know About Mortgage Interest

Comments 2 Comments

Mortgage interest is a double-edged sword. On one hand, it’s a tax-deductible expense, but, by and large, it is the heaviest cost of homeownership.

Of course, deciphering how much interest you have left to pay off on a mortgage can be tricky. Here are a few quirks to be aware of if you’re looking to buy or refinance a home.

1. Interest Works the Opposite of Rent

The amount of money you’re borrowing is based on a certain interest rate paid over the term of your loan. The longer the term the more interest you pay, spread out over the entire life of the loan. A shorter-term loan is more condensed with a higher payment each month, but less total interest paid overall.

Like rent, loan interest is paid in months. When you start paying your 30-year mortgage, for example, part of your monthly payment will go to principal, but the lion’s share goes to interest. It is not until year 10 that the inverse occurs and more of the payment starts going to principal. The majority of the principal will then be paid off during the remaining 20-year term left on the original 30-year loan.

Rent is due on the first of the month for that month’s obligation. Mortgage interest works in arrears. When you make your mortgage payment at the beginning of the month, you are paying the interest of the previous month.

Remember, a good credit score entitles you to better rates on your mortgage, so it may be a good idea to check yours before you apply for the loan. You can see your credit reports for free each year at AnnualCreditReport.com and your credit scores for free each month at Credit.com.

2. Refinancing Is More Complicated Than You Think

Keep in mind that when you refinance, your principal balance on a credit report or mortgage statement is not a payoff amount. The payoff is always higher than the current principal. That’s because the lender must estimate the amount of interest they need to collect before the loan term is up. The simple way to estimate a payoff when you refinance your home is to add a mortgage payment to your current principal. While this is not an exact calculation, it is a safe budgeting estimate when determining what you want your new loan amount will be.

Most mortgage lenders are nimble enough to tie your recent loan payment to your payoff amount. This is also a way to make your numbers lower at loan settlement (escrow closing). But if your loan is closing just after the first of the month and you’ve already made your mortgage payment, the payment could be refunded to you after closing or put towards the payoff amount.

Refinancing your home does not mean skipping a mortgage payment. Let’s say you close your loan Oct. 15: your new lender would begin charging you interest from the date that they finance onward. This means you begin incurring interest from Oct. 15 through Nov. 1 with your first payment on the new loan not due until Dec. 1. While you do not make a payment in the first month after refinancing, you are still paying for it in interest as part of the next month’s payment.

3. You Prepay a Month’s Interest When You Close on a Home

The same interest concept applies when you close on a new home purchase. Your loan estimate will show the amount of prepaid interest your lender is using to estimate the amount of time it will take to close on your new loan. The prepaid interest amount can be adjusted based upon your closing date.

Referencing our October loan closing examples: if your loan closes just after the first of the month (say Oct. 5), you won’t have to make a mortgage payment until Dec. 1. All of the interest for November will be reflected in the Dec. 1 payment and the interest for October will be collected at closing in the form of prepaid interest.

Interest is a driver of cash-to-close and is a re-occurring cost, meaning it’s an ongoing expense of homeownership, just like property taxes or insurance. The more informed you are as a mortgage borrower, the smarter choices you can make when applying for a home loan. Remember, if something does not jive within the origination of your loan, ask your loan professional. They should be able to clearly explain any and all related mortgage interest questions.

      You can check a refinance calculator online (one that allows you to plug in additional payments) to check. The information you gave us is, unfortunately, not enough to go on. But you can easily find a calculator to get that information.

Certain credit cards and other financial products mentioned in this and other articles on Credit.com News & Advice may also be offered through Credit.com product pages, and Credit.com will be compensated if our users apply for and ultimately sign up for any of these cards or products. However, this relationship does not result in any preferential editorial treatment.

Hello, Reader!

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.

Our Business Model

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.

Our Owners

Credit.com is owned by Progrexion Holdings Inc. which is the owner and administrator of a number of business related to credit and credit repair, including CreditRepair.com, and eFolks. In addition, Progrexion also provides services to Lexington Law Firm as a third party provider. Despite being owned by Progrexion, it is not the role of the Credit.com editorial team to advocate the use of the company’s other services. In articles, reporters may mention credit repair as an option, for example, but we’ll also be sure to note the various alternatives to that service. Furthermore, you may see ads for credit repair services on Credit.com, but the editorial team isn’t responsible for the creation or implementation of those ads, anymore than reporters for the New York Times or Washington Post are responsible for the ads on their sites.

Your Stories

Lastly, much of what we do is informed by our own experiences as well as the experiences of our readers. We want to tell your stories if you’re interested in sharing them. Please email us at story ideas [at] credit [dot] com with ideas or visit us on Facebook or Twitter.

Thanks for stopping by.
