What actually moves your mortgage rate

Your mortgage rate is set by a combination of things you control and things you don't. The things you don't control are the market — the Federal Reserve's decisions, inflation, bond yields — which affect what banks charge everyone. The things you do control are your credit score, down payment size, loan type, and how long you lock in the rate.

A bank quotes you a rate based on the risk they see in lending to you. A higher credit score, a larger down payment, and a shorter loan term all signal lower risk, which means a lower rate. You cannot change the market overnight, but you can change how risky you look to a lender.

Key Takeaways

  • Your credit score is the single biggest lever you control — a 20-point improvement can lower your rate by 0.25% or more, which saves tens of thousands over the life of the loan.
  • A larger down payment reduces the lender's risk and almost always lowers your rate, even if it means waiting a few months to save.
  • Shopping with multiple lenders in a short window (usually 14 days) counts as a single credit inquiry and lets you compare real offers without penalty.
  • Paying points — an upfront fee to the lender — can lower your rate permanently, but only makes sense if you stay in the home long enough to break even.
  • The type of loan matters: a 15-year fixed mortgage typically has a lower rate than a 30-year, but a higher monthly payment.

Improve your credit score before you apply

Your credit score is the fastest way to move your rate. Most mortgage lenders use your FICO score, and the difference between a 620 and a 740 can be 1% or more on your rate. That difference costs you roughly $200 per month on a $300,000 loan.

The main things that move your score are payment history (35% of the score), amounts you owe relative to your limits (30%), and length of credit history (15%). If you have missed payments, bring them current first — that is the single biggest repair. If you have high credit card balances, pay them down before you apply. Even dropping from 80% of your limit to 30% can raise your score 50 to 100 points in a month or two.

Do not open new credit accounts in the months before you apply. Each new account lowers your score temporarily and signals to the lender that you are taking on more debt. If you already have the accounts open, leave them open — closing them can actually hurt your score by raising your utilization ratio on the cards you keep.

Save for a larger down payment

The more money you put down, the less the lender is risking, and the lower your rate will be. A 20% down payment typically gets you a better rate than 10%, which gets a better rate than 5%. The difference is usually 0.25% to 0.5%, which again translates to tens of thousands of dollars saved.

A larger down payment also lets you avoid private mortgage insurance (PMI), which is an extra monthly fee the lender charges when you put down less than 20%. PMI typically costs 0.5% to 1% of your loan amount per year. So if you can delay buying for six months and save an extra 5% down, you often come out ahead even accounting for rent you pay in the meantime.

If you have family who can gift you down payment money, that counts as your own funds for the lender's purposes — you do not have to repay it. The gift giver will need to sign a letter stating it is a gift, not a loan, but there is no tax consequence to either of you.

Shop with multiple lenders in a short window

Different lenders quote different rates for the same borrower. The difference between the lowest and highest quote you receive might be 0.5% or more. Shopping around is the fastest way to find the best rate available to you right now.

When you request a quote, the lender pulls your credit report, which creates a hard inquiry. Multiple hard inquiries in a short time normally hurt your score, but mortgage shopping is an exception. If you shop within 14 days (some scoring models allow 45 days), all the inquiries count as one. This means you can get quotes from five lenders without penalty.

Request quotes from at least three lenders: a large national bank, a mortgage broker or credit union, and a direct online lender. Each operates differently and may price your loan differently. When you compare quotes, make sure you are comparing the same loan — same down payment, same loan term, same property type. A quote for a 30-year fixed at 6.5% is not the same as a 7-year ARM at 5.8%.

Understand points and when they make sense

Points are an upfront fee you pay to the lender in exchange for a lower rate. One point costs 1% of your loan amount. So on a $300,000 loan, one point costs $3,000 and typically lowers your rate by 0.25%.

Points only make financial sense if you stay in the home long enough to break even. If one point costs $3,000 and saves you $75 per month, you break even after 40 months (about 3.3 years). If you plan to sell or refinance before that, paying points loses you money. If you plan to stay 10 years or longer, points usually save you money.

Some lenders also offer lender credits, which is the opposite: the lender gives you money at closing in exchange for a higher rate. This makes sense if you need cash at closing or plan to move within a few years. Ask every lender whether they offer credits as an alternative to points.

Choose a shorter loan term if you can afford it

A 15-year mortgage almost always has a lower rate than a 30-year mortgage. The difference is usually 0.5% to 0.75%. Because you are paying the loan off faster, the lender's risk is lower.

The trade-off is your monthly payment. On a $300,000 loan at 6%, a 30-year mortgage is about $1,800 per month, while a 15-year is about $2,700. That extra $900 per month is real money. Only choose a 15-year if your income is stable and your budget has room for it. A 30-year mortgage you can afford beats a 15-year mortgage that stretches you too thin.

Lock your rate at the right time

Once you have chosen a lender and received a quote, you can lock your rate, which means the lender guarantees that rate for a set number of days — usually 30, 45, or 60. If rates rise during that time, you keep your locked rate. If rates fall, you are stuck with the higher one.

Locking too early means you might miss a rate drop. Locking too late means rates might rise before your loan closes. There is no perfect time — it depends on market conditions and your comfort with risk. Most people lock when they have a solid offer on a home and have chosen their lender, which is usually 30 to 45 days before closing.

Ask your lender whether they offer a rate float-down option, which lets you lock a rate but still benefit if rates drop before closing. This costs a fee, but it removes the guessing game.

Frequently Asked Questions

Does refinancing make sense if rates only drop 0.25%?

It depends on how long you plan to stay. Refinancing costs 2% to 5% of your loan amount in closing costs. On a $300,000 loan, that is $6,000 to $15,000. If you save $75 per month, you break even after 80 to 200 months. If you plan to move within five years, refinancing probably does not pay. If you plan to stay longer, it might.

Can I negotiate my mortgage rate with the lender?

Not directly — the lender sets rates based on market conditions and your risk profile. But you can negotiate other costs: origination fees, appraisal fees, and title insurance. You can also shop lenders, which is the real negotiation. The lender who wants your business most will offer the best combination of rate and fees.

What is the difference between APR and interest rate?

The interest rate is what you pay on the loan balance. The APR includes the interest rate plus all other costs — points, origination fees, insurance — expressed as a yearly percentage. The APR is always higher than the rate and is the number you should compare between lenders, because it shows the true cost.

Should I get pre-approved or pre-may have access to?

Pre-qualification is informal — the lender estimates what you might borrow based on what you tell them. Pre-approval is formal — the lender verifies your income, credit, and assets and commits to a rate for 30 to 60 days. Pre-approval is what sellers take seriously and what you need before you make an offer. It also locks in your rate while you shop for homes.

Can I lower my rate without refinancing?

No. Your rate is set when you close the loan and does not change unless you refinance. Some lenders offer a one-time rate adjustment within a set period after closing, but this is rare and usually only for new customers. If rates drop significantly after you close, refinancing is your only option.
