Mortgage rates come down to the broader economy, which sets the general level of rates everyone sees, and your personal financial profile, which decides where your rate lands within that range.
Market conditions like inflation and Federal Reserve policy move the baseline up and down for the whole country. Then your credit score, down payment, loan type, and a handful of other factors adjust your individual rate from there. The Consumer Financial Protection Bureau puts it simply: it's not any single factor but the combination that determines the rate you're offered.
That's why two people can apply for a mortgage on the same day and get different rates, and why the number you see advertised online rarely matches what you're actually quoted. Understanding both sides of the equation helps you tell a fair offer from one worth negotiating, and it points to the specific things you can change to earn a lower rate.
The Market Forces
Before any lender looks at your application, the general level of mortgage rates is already set by conditions across the wider economy. These are the factors no borrower controls, but they explain why rates rise and fall over time.
Inflation and the bond market
Long-term fixed mortgage rates track the bond market far more closely than most people assume. They tend to follow the 10-year Treasury yield, which lenders use as a benchmark for pricing home loans. When inflation runs high, investors demand higher yields to compensate, and mortgage rates climb along with them. When inflation cools, the reverse tends to happen.
The Federal Reserve
A common misconception is that the Federal Reserve sets mortgage rates directly. It doesn't. The Fed sets the federal funds rate, an overnight bank-lending rate, which influences short-term borrowing more directly than long-term mortgages. As the Federal Reserve Bank of Atlanta explains, the fed funds rate and mortgage rates aren't joined at the hip. They can even move in opposite directions, because long-term mortgage pricing responds more to investor expectations about future inflation and growth than to the Fed's current setting.
The practical takeaway: when you read that "the Fed cut rates," your mortgage rate won't necessarily drop in step. It may already have moved in anticipation, or move the other way entirely.
The Personal Factors You Can Influence
Once the market sets the baseline, lenders price your individual rate based on how much risk your loan represents. Here's where your own choices carry real weight. The CFPB identifies seven key factors that shape the rate you're offered.
Credit score
Your credit score is one of the biggest levers. In general, borrowers with higher credit scores receive lower interest rates, because the score signals to lenders how reliably you've repaid debt in the past. Even a modest improvement can matter. The CFPB's own Explore Interest Rates tool shows that moving from one credit score range to a higher one can change the rates available to you meaningfully over the life of a loan, and it also tends to open up more lenders willing to compete for your business.
Before you shop, check your credit reports for errors and dispute anything inaccurate. A mistake dragging your score down can quietly cost you a better rate, and corrections take time, so start early.
Down payment and loan-to-value
A larger down payment generally earns a lower rate, since more money down means less risk for the lender. Your down payment determines your loan-to-value (LTV) ratio, the share of the home's value you're financing. Put 20 percent down and your LTV is 80 percent.
There's a wrinkle worth knowing. On a conventional loan, putting down less than 20 percent usually triggers private mortgage insurance (PMI), which protects the lender and adds to your monthly cost. This is one area where VA loans differ sharply, since they require no down payment and no monthly mortgage insurance, a structural advantage that changes this calculation entirely for eligible Veterans.
Because of PMI, a slightly lower rate with under 20 percent down doesn't always mean a lower total cost. The CFPB stresses looking at your full cost to borrow, not the interest rate alone, since the added insurance payments can outweigh the savings from a marginally better rate.
Loan amount and home price
Very small and very large loans can both carry higher rates. Your loan amount is essentially the home price plus closing costs minus your down payment, and where that figure lands can nudge your rate one way or another.
Loan term
The length of your loan affects the rate. Shorter terms, like a 15-year loan, generally come with lower interest rates and less total interest paid, but higher monthly payments. Longer terms, like the common 30-year loan, spread payments out and lower the monthly cost while raising the total interest over time.
Interest rate type
A fixed rate stays the same for the life of the loan. An adjustable rate (ARM) may start lower during an initial fixed period, then rise or fall with the market afterward. That lower starting rate can be appealing, but it comes with the risk of a significant increase later, so the comparison isn't just about the opening number.
Loan type
Conventional, FHA, USDA, and VA loans are priced differently, and rates can vary noticeably between them. Each has its own eligibility rules, and the right fit depends on your situation. For eligible Veterans, service members, and surviving spouses, VA loans carry a government guaranty that lets lenders offer competitive terms without a down payment or monthly mortgage insurance.
The Points and Credits Trade-Off
Beyond these factors, you have one more lever at the point of quoting: discount points and lender credits. The CFPB describes this as a set of trade-offs in how you pay for the loan.
- Discount points lower your interest rate in exchange for an upfront fee. Paying points costs more at closing but less over time, which can pay off if you'll hold the loan for many years.
- Lender credits work in reverse. They reduce your upfront closing costs in exchange for a higher interest rate, so you pay less now and more over time.
The right choice depends on how long you plan to keep the loan and how much cash you want to spend upfront.
Understanding what moves your rate is the first step toward getting a better one. To go deeper, read more about VA loans and how to put the benefit you earned to work.
FAQs
Does the Federal Reserve set mortgage rates?
No. The Fed sets the federal funds rate, which affects short-term borrowing more directly. Long-term mortgage rates follow the bond market and investor expectations about inflation and growth, so they don't always move in step with the Fed.
What has the biggest effect on my personal mortgage rate?
Your credit score, down payment, and loan type are among the most influential. Together they signal how much risk your loan carries, which is what lenders price into your rate.
Why is my rate different from the rate my friend got?
Because rates are tailored to each borrower. Differences in credit score, down payment, loan type, loan term, and even the day you locked your rate can all produce different offers for two people buying similar homes.
Can I get a lower rate by improving my credit before applying?
Often, yes. Since higher credit scores generally earn lower rates, checking your reports for errors and paying down balances before you apply can help. Corrections take time, so it's worth starting well before you shop.
Are VA loan rates different from conventional rates?
They can be, because VA loans are backed by a government guaranty and require no down payment or monthly mortgage insurance, which affects overall cost. As with any loan type, comparing offers from multiple lenders is the way to find your best rate.
