The 5 Biggest Things That Affect Your Mortgage Rates


One of the most frequent discussions we have with clients revolves around why their mortgage rate differs from the rates advertised on TV. Mortgage rates are influenced by various factors, which is why your loan rate may differ from that of your friends or family. The rates you see on TV typically reflect what lenders consider an ideal loan scenario, but in reality, those advertised rates apply to less than 5% of California mortgage loans.

In this article, we share the top 5 factors that affect the interest rate on your mortgage loan.

The first factor is outside of your control, as well as your lender’s. However, factors 2 through 5 are considered varying levels of risk by lenders. Your mortgage interest rate is partially determined by how you measure up against these five key factors.

First, General Market Rates. The baseline mortgage rates are determined by current interest rates established by the financial markets, which are influenced by a wide range of economic factors. These rates fluctuate in response to the overall health of the economy, including key indicators such as inflation, unemployment rates, and trade balances. For example, when inflation rises, lenders may increase mortgage rates to maintain their profit margins. Similarly, if the jobless rate drops, signaling a stronger economy, mortgage rates might rise due to increased demand for loans.

Second, Credit Scores. The lower your credit score, the higher the interest rate you’ll likely be offered on your mortgage loan. This is because lenders view borrowers with lower credit scores as higher risk. When your credit score is low, it suggests to lenders that you may have a history of missed or late payments, high debt levels, or other financial issues that increase the likelihood of defaulting on the loan. To compensate for this increased risk, lenders charge higher interest rates, which helps protect them from potential losses. Conversely, borrowers with high credit scores are seen as more reliable and financially stable, leading to lower interest rates and more favorable loan terms.

Third, Debt vs Income. Even if you have a high income, owing a significant amount of money on personal loans, credit cards, auto loans, or other financial obligations can result in a higher mortgage interest rate. Lenders assess your financial situation by looking at your Debt-to-Income Ratio (DTI), which is the percentage of your monthly income that goes toward paying off existing debts. A high DTI indicates that a large portion of your income is already committed to debt payments, making you a riskier borrower in the eyes of lenders. This perceived risk can lead to a higher mortgage rate, as lenders may charge more to offset the possibility that you might struggle to keep up with additional mortgage payments. In contrast, borrowers with lower DTI ratios, who have less debt relative to their income, are generally offered lower interest rates because they are seen as more capable of managing their financial obligations.

Fourth, Loan to Value.  If your home is valued at $500,000 and your mortgage loan is $400,000, your Loan-to-Value (LTV) ratio is 80%. LTV is a key metric that lenders use to assess the risk associated with a mortgage loan. It represents the proportion of the property’s value that is being financed through the loan. A borrower with a lower LTV ratio, such as 70%, will typically secure a lower mortgage interest rate compared to someone with an 80% LTV. This is because a lower LTV ratio indicates that the borrower has more equity in the property, reducing the lender’s risk.

Fifth, Loan Size. Every county in the U.S. has a loan limit set by federal guidelines, known as the conforming loan limit. This limit determines the maximum loan amount that can qualify for backing by government-sponsored enterprises like Fannie Mae and Freddie Mac. If your mortgage loan is at or below this conforming limit, you are likely to receive a lower interest rate because the loan is considered less risky and more desirable to lenders.

However, if you need to borrow more than this limit, your loan becomes a “jumbo loan,” which typically comes with a higher interest rate due to the increased risk to the lender. Jumbo loans are not eligible for purchase by Fannie Mae or Freddie Mac, which means they lack the same government backing and are subject to stricter credit requirements and higher rates.
