Where mortgage rates actually come from
Mortgage rates are not set by a single place or person. Banks and lenders set their own rates based on what the Federal Reserve does with short-term interest rates, what investors will pay for mortgages on the secondary market, and how much it costs that lender to do business. When you see "mortgage rates today" quoted somewhere, you are seeing what individual lenders are offering right now — not a fixed number that applies everywhere.
This means the rate you are offered depends on three things: which lender you ask, what type of mortgage you want (15-year fixed, 30-year fixed, adjustable-rate), and your own financial picture (credit score, down payment size, debt-to-income ratio). A lender offering 6.5% to one borrower might offer 6.8% to another, even on the same day.
Key Takeaways
- Mortgage rates vary by lender, loan type, and your credit profile, so comparing offers from at least three different lenders is the only way to know what you can actually get.
- Mortgage brokers can show you rates from multiple lenders at once, but they are paid by the lender, not by you, so their incentive is to close the loan, not to find you the lowest rate.
- The Federal Reserve's actions move all rates in the same direction, but individual lenders respond at different speeds and by different amounts.
- Your credit score, down payment amount, and loan-to-value ratio directly affect the rate you are offered, sometimes by a full percentage point or more.
- Rate quotes are usually good for 24 to 48 hours, so gathering multiple quotes in a short window lets you compare apples to apples.
How to gather rate quotes from lenders
Start by contacting banks and mortgage lenders directly. Most have a mortgage department or a dedicated mortgage website where you can request a quote. You will need to provide basic information: the loan amount you want, the property price, your down payment amount, your credit score range (or permission to pull it), and the loan type (30-year fixed, 15-year fixed, or adjustable-rate). Some lenders let you do this online; others require a phone call.
Contact at least three lenders. This takes a few hours but gives you real numbers to compare. Ask each lender for the same loan type and terms so the quotes are actually comparable. Write down the interest rate, the annual percentage rate (APR), the loan origination fee, and how long the quote is good for. The APR includes the interest rate plus fees, so it is a better number for comparing total cost than the rate alone.
Do all your rate shopping within a two-day window if you can. Credit inquiries for mortgage shopping are grouped together and count as a single inquiry on your credit report, but only if they happen within 14 to 45 days depending on the credit scoring model. Doing them close together protects your credit score.
Using mortgage brokers to see multiple lenders at once
A mortgage broker is a person or company that works with multiple lenders and can show you rates from several of them in one conversation. This saves you the time of calling each lender separately. The broker pulls your credit, gathers your financial information once, and then runs it through their network of lenders to see what each one will offer.
The catch is that brokers are paid by the lender when the loan closes, not by you. Their business model depends on closing loans, so they have an incentive to move you toward a deal rather than to hunt for the absolute lowest rate. Some brokers are more diligent than others, but this conflict of interest is built in. Use a broker for convenience, but still compare their best offer against quotes you get directly from at least one bank.
Ask the broker upfront how many lenders they work with and whether they will show you rates from all of them or just a subset. Some brokers have preferred relationships with certain lenders and may not show you all available options. Get that answer in writing if you can.
What moves rates up and down
The Federal Reserve does not set mortgage rates directly, but its actions move them. When the Fed raises its benchmark interest rate, mortgage rates tend to rise within days or weeks. When the Fed cuts rates, mortgage rates usually fall. The lag is not instant because mortgage lenders watch the Fed's signals and market expectations, not just the official rate itself.
Inflation also moves rates. When inflation is high, lenders demand higher rates to protect themselves against the loss of purchasing power. Economic data like employment numbers and inflation reports can shift rates by a tenth of a percent or more in a single day.
Your personal financial picture affects the rate you are offered. A borrower with a 750 credit score and a 20% down payment will get a lower rate than a borrower with a 650 score and a 5% down payment, even from the same lender on the same day. Loan-to-value ratio (how much you are borrowing compared to the home's value) matters too. The more you put down, the lower your rate.
Understanding rate locks and float-downs
When a lender gives you a rate quote, that rate is usually good for 24 to 48 hours. If you want to lock in that rate before closing, you ask the lender to lock it. A rate lock means the lender promises to give you that rate at closing, even if rates rise between now and then. Locks typically last 30 to 60 days, though you can pay for longer locks.
If rates fall after you lock, you are stuck with your locked rate unless the lender offers a float-down. A float-down lets you take a lower rate if rates drop before closing. Not all lenders offer this, and some charge a fee for it. Ask about float-down options before you lock.
Do not lock too early. If you lock 60 days before closing and rates fall, you may not be able to take advantage of the drop. Lock when you are close to closing and confident in your timeline.
Comparing offers side by side
When you have quotes from multiple lenders, lay them out in a table or spreadsheet. Include the interest rate, the APR, the origination fee, any discount points (if you are considering paying upfront to lower the rate), the loan term, and how long the quote is good for. The APR is the most important number because it includes both the rate and the fees.
Do not choose based on rate alone. A lender with a slightly higher rate but lower fees might cost you less overall. Use a mortgage calculator to estimate your total cost over the life of the loan, factoring in both the rate and the fees. A difference of 0.25% in rate costs you thousands over 30 years, but so does a difference of $2,000 in origination fees.
Ask each lender about their closing timeline and whether they have any hidden fees. Some lenders charge for appraisals, inspections, or title work upfront; others roll these into the closing costs. Understand what you are paying for and when.
When to lock and when to wait
If rates are falling and you are not under time pressure, waiting a few days might get you a better rate. If rates are rising and you are confident in your timeline, locking sooner protects you. There is no perfect answer because nobody knows what rates will do tomorrow.
Lock if you are within 30 to 45 days of closing and rates are at a level you are comfortable with. If you are further out, you can shop around without locking, but understand that your quote will expire and you will need to ask for a new one when you are ready to move forward.
If you are buying a home and your offer is contingent on a home inspection or appraisal, do not lock until those contingencies are removed. Locking early and then having the deal fall through means you may lose your lock or pay a fee to move it to a different property.
Frequently Asked Questions
Do all lenders offer the same rates?
No. Lenders set their own rates based on their cost of funds, their risk appetite, and their business strategy. On the same day, one lender might offer 6.5% and another 6.75% for the same loan type and borrower profile. This is why shopping around matters.
How much does my credit score affect the rate I get?
A lot. A borrower with a 740 credit score might get a rate 0.5% to 1% lower than a borrower with a 620 score. Over a 30-year loan, that difference costs tens of thousands of dollars. If your score is below 700, paying to improve it before you apply might save you more than the cost of the improvement.
Can I negotiate my mortgage rate?
Not really. Rates are set by market conditions and your financial profile, not by negotiation. What you can do is shop around to find the lender offering the best rate for your situation, and you can ask about paying discount points to lower your rate if you plan to stay in the home a long time.
What is the difference between APR and interest rate?
The interest rate is what you pay to borrow the money. The APR includes the interest rate plus lender fees, expressed as an annual percentage. APR is a better number for comparing total cost between lenders because it accounts for fees. A lender with a lower rate but higher fees might have a higher APR.
How long does a rate quote stay good?
Usually 24 to 48 hours. Some lenders offer longer quotes, but they are rare. If you are gathering quotes from multiple lenders, do it within a short window so all your quotes are current and comparable.
