Higher mortgage interest rates lead to higher monthly payments. It can make a big difference to your short- and long-term financial health.

For example, according to Navy Federal Credit Union, dropping your rate by half a percent can save you thousands of dollars. On a $300,00 home, dropping the interest rate from 7.0 percent to 6.5 percent with a 20 percent down payment saves you roughly $80 per month. But more important, for the long term, it saves you more than $28,000 over a 30-year loan.

So, finding the best mortgage rate is imperative. But how can you affect your mortgage interest rate? There are strategies that can put you in a strong position to save money.

Credit Score Is the Biggest Factor

Your credit score is the biggest factor in a lender’s decision on your interest rate.

According to Zions Bank, a 100-point difference in your FICO score could change your monthly payment by hundreds of dollars. It could affect your overall interest payments by tens of thousands of dollars.

You need to have upward of a 740 credit score to qualify for the best rates. You might be able to qualify with a lower credit score with some types of loans, but you’ll end up paying more in interest.

Shop Mortgage Rates

Shopping around for the best mortgage interest rate is well worth the effort and a strategy that every homebuyer should do.

According to the Consumer Financial Protection Bureau (CFPB), credit checks from lenders are reported to credit reporting companies as an “inquiry.” They typically have a small negative effect on your credit score and can be seen by other lenders when they check your credit.

Shopping around for a mortgage doesn’t hurt your credit. That’s because, according to the CFPB, within a 45-day window, multiple credit checks from mortgage lenders are recorded on your credit report as one inquiry. After all, you are only going to buy one house.

Even if you’re outside the 45-day window, the effect of an additional inquiry is small.

Keep in mind, regardless of the timing, that shopping around for the best deal can save you a lot of money in the long run.

It’s important to prequalify for a loan with at least three lenders to have an idea of the rates you qualify for. Although you won’t receive a formal offer, you can use prequalification to estimate the potential rate and eliminate lenders who are not a good fit.

Consider a Shorter Loan Term

You can also save money by considering a shorter term; for example, choosing a 15-year period over a 30-year period.

Although shorter terms typically save you money overall, they have higher monthly payments.

According to the CFPB, with a shorter term, you will be borrowing money and paying interest for a shorter amount of time. This ultimately saves you money.

One of the biggest advantages of considering a shorter term is that the interest rate is usually lower. In fact, it can be as much as a full percentage point lower than a standard rate.

However, much depends on specifics. You’ll want to look at interest rates, but you’ll also want to take into account how much higher your monthly payment will be. Rates vary among lenders, so you should research current 15-year and 30-year average mortgage rates.

Always compare the official loan estimate before making your decision.

Lower Your Debt-to-Income Ratio

Lenders will stress your FICO score, but they’ll also take a hard look at your debt-to-income (DTI) ration. They use this to determine if you can afford a potential monthly payment.

To determine your DTI, add up your monthly debts and divide that number by your pretax monthly income. Your DTI is the final number, expressed as a percentage.

Typically, the higher your DTI is, the higher interest rate you’ll have to pay. If it’s too high, you may not even qualify for a mortgage.

According to Wells Fargo, a DTI ratio of 35 percent or less is considered good and means your debt is at a manageable level. Lenders generally view a lower DTI ratio as favorable.

Thirty-six percent to 49 percent means you’re managing your debt adequately but need to improve. If you have 50 percent or more, you’ll need to pay down debt. With this DTI ratio you may be limited as to how much you can borrow and you may have a higher interest rate.

If you want to qualify for a lower interest rate, it’s important to have a low DTI ratio.

Lower Your Credit-Utilization Ratio

This goes along with your DTI ratio. A credit-utilization ratio measures how much you owe across all open revolving lines, such as credit card accounts and home-equity lines of credit. It then compares that to your total credit limit.

According to Equifax, lenders use this to determine how well you manage your current debt. And, typically, lenders want to see that you use no more than 30 percent of the total revolving debt.

Before applying for a mortgage, it’s important to ensure you’re not using a large portion of your credit if you want to qualify for a low interest rate.

Control What You Can When Applying for a Low Interest Rate

There are many elements to applying for a mortgage that you may not have control over. But by striving for an excellent credit score and DTI ratio, you can start the conversation in a better position.
Consider a shorter term on the loan to save money over the longer term. And take advantage of shopping for the lowest interest rate. It won’t hurt your credit, and it could save you money.
