What Determines Your Mortgage Rate?
Mortgage rates begin with the financial markets, but your final rate is adjusted according to the risk and structure of your loan.
Lenders generally consider:
- Credit score and credit history
- Down payment and loan to value ratio
- Loan amount
- Property type
- Primary residence, second home, or investment property occupancy
- Fixed rate or adjustable rate structure
- Loan term
- Conventional, FHA, VA, jumbo, or non QM financing
- Whether you pay discount points or receive lender credits
- Length of the rate lock
This is why asking, What is your rate? is not enough. A meaningful mortgage quote must be based on a complete scenario.
1. Improve Your Credit Before Applying
Credit is one of the biggest borrower controlled pricing factors. A stronger mortgage credit profile can improve the interest rate, reduce mortgage insurance costs, and expand your loan options.
Before applying:
- Review all three credit reports for inaccurate information
- Pay revolving balances down when practical
- Make every payment on time
- Avoid opening new accounts unless necessary
- Do not close older credit accounts without first considering the effect on utilization and credit history
- Avoid financing a car, furniture, or another large purchase before closing
Here is the thing: the score shown by a consumer credit app may not match the mortgage score used by a lender. Have a qualified mortgage professional review the actual lending profile before making major credit moves. Paying off the wrong account at the wrong time can accomplish very little.
2. Compare the Right Loan Programs
The loan with the lowest note rate is not necessarily the least expensive loan.
A conventional loan may offer competitive pricing for a borrower with strong credit, but private mortgage insurance can affect the total payment when the down payment is below 20 percent. FHA financing may offer attractive note rates and more flexible qualifying standards, but it includes upfront and annual mortgage insurance. VA loans often provide excellent pricing for eligible borrowers, but the VA funding fee and individual exemption status must be considered. Jumbo and non QM programs use their own pricing models.
The correct comparison should include:
- Interest rate
- APR
- Principal and interest payment
- Mortgage insurance
- Upfront program fees
- Total closing costs
- Cash required to close
- Cost over the period you expect to keep the loan
The best mortgage rate exists only in the context of the right loan program.
3. Increase Your Down Payment Strategically
A larger down payment reduces the lender’s risk and may improve pricing. It can also reduce or eliminate mortgage insurance.
But more money down does not always produce a proportionate rate improvement. Pricing can change at specific loan to value thresholds, depending on the loan program and borrower profile.
Ask your mortgage advisor to price several down payment options. For example, compare 5 percent, 10 percent, 15 percent, 20 percent, and 25 percent down when appropriate. Then evaluate the rate, mortgage insurance, monthly payment, reserves, and opportunity cost of using additional cash.
Draining your savings merely to obtain a slightly lower rate may leave you house rich and cash poor. That is not a win.
4. Compare Mortgage Quotes on the Same Day
Mortgage pricing can change daily and sometimes during the same day. Comparing a Monday quote from one lender with a Thursday quote from another is not a valid comparison.
Request quotes for the same:
- Loan amount
- Property value or purchase price
- Down payment
- Credit score
- Loan program
- Loan term
- Occupancy
- Rate lock period
- Number of discount points
The Consumer Financial Protection Bureau recommends contacting at least three lenders and comparing formal Loan Estimates. Freddie Mac also recommends comparing loan offers on the same day because rates change frequently.
5. Compare Interest Rate, APR, Points, and Fees
The note rate determines the interest used to calculate the principal and interest payment. APR is a broader measure that incorporates the interest rate and certain borrowing costs.
According to the CFPB explanation of mortgage APR, APR generally includes the rate, points, mortgage broker fees, and certain other charges. It is useful, but it should not be your only comparison tool because it assumes a particular loan life and may not capture every practical difference between offers.
Review these sections of each Loan Estimate:
- Page 1 for the rate, monthly principal and interest, prepayment penalty, and rate lock status
- Page 2, Section A for lender controlled origination charges and discount points
- Page 2 for lender credits and total closing costs
- Page 3 for APR and the five year cost of borrowing
Do not compare a rate with two points against a rate with no points and declare the first lender cheaper. That is apples versus a fruit basket with a financing department.
6. Calculate the Break Even Point Before Paying Discount Points
One discount point equals 1 percent of the loan amount. Paying points can reduce the interest rate, but the rate reduction is not fixed and varies with the market, lender, and loan program.
Use this simple calculation:
Break even period = upfront cost of points divided by monthly payment savings
If points cost $6,000 and reduce the monthly payment by $100, the simple break even period is 60 months.
Paying points may make sense if you expect to keep the mortgage beyond the break even period. It may be a poor choice if you expect to sell, refinance, or pay off the loan sooner.
The CFPB guidance on points and lender credits recommends comparing options over several possible time periods. That is the right way to make the decision.
7. Consider the Loan Term and Rate Structure
Shorter fixed rate terms often carry lower rates than 30 year loans, but the required payment is higher. A 15 year mortgage can reduce total interest substantially, but only if the payment fits comfortably within your budget.
An adjustable rate mortgage may offer a lower initial rate than a fixed rate mortgage. However, the initial rate, adjustment index, margin, adjustment frequency, and rate caps all matter. A lower starting rate is not automatically a better long term deal.
Choose the structure that matches how long you expect to own the property or keep the loan. Do not choose a loan solely because its first payment looks attractive.
8. Protect Your Financial Profile Before Closing
A mortgage approval and rate can be affected by changes before closing.
Until the loan funds:
- Keep making all payments on time
- Do not apply for new credit
- Do not increase credit card balances substantially
- Do not change employment without discussing it with your loan officer
- Do not move large sums between accounts without keeping documentation
- Do not make large unexplained cash deposits
Lenders may verify credit, employment, assets, and liabilities again before closing. The quiet period between approval and funding is not the time to buy a new truck. The truck will still be there after closing. Your approval may not be.
9. Decide When to Lock Your Mortgage Rate
A rate quote is not the same as a locked rate. A rate lock is a written agreement that protects specified pricing for a defined period, subject to the terms of the lock and the accuracy of the application.
Before locking, confirm:
- The exact interest rate
- Discount points or lender credits
- Lock expiration date
- Whether the property is identified
- Float down options, if any
- Extension costs if closing is delayed
- What changes could affect the locked pricing
Trying to predict the perfect bottom in mortgage rates is speculation. A sound lock decision should protect the closing and fit the borrower’s financial plan.
10. Work With a Mortgage Professional Who Can Explain the Numbers
The best mortgage professional is not the person who promises the lowest rate before reviewing the file. It is the person who can price the correct scenario, identify underwriting risks, compare programs, explain the tradeoffs, and close the loan on time.
A mortgage broker can compare options across multiple wholesale lenders. That can be especially valuable for self employed borrowers, real estate investors, jumbo borrowers, and clients with complex income or asset structures.
Ask for a written comparison showing the rate, points, lender credits, closing costs, payment, cash to close, and break even period. If the numbers cannot be explained clearly, keep shopping.
Can Shopping for a Mortgage Hurt Your Credit?
Mortgage credit inquiries made within a concentrated shopping period are generally treated as a single inquiry for credit scoring purposes. The CFPB states that multiple mortgage credit checks within a 45 day window are recorded as a single inquiry.
Scoring models and lender practices can vary, so it is still smart to keep mortgage shopping focused and avoid unrelated credit applications.
The Bottom Line
To get the best mortgage rate, strengthen your credit, compare appropriate loan programs, price multiple down payment options, shop several lenders on the same day, and evaluate the complete cost of each offer.
Most importantly, define what best means for you. The lowest rate may require expensive points. The lowest closing cost may require a higher rate. The right choice depends on your available cash, expected holding period, risk tolerance, and financial goals.

Frequently Asked Questions
What credit score is needed to get the best mortgage rate?
There is no single score that guarantees the best rate. Pricing depends on the loan program, loan to value ratio, occupancy, property type, and other factors. Higher scores generally improve conventional loan pricing, but the meaningful pricing thresholds vary by scenario.
Is it better to use a mortgage broker or a bank?
Neither channel is automatically cheaper in every case. A mortgage broker can compare multiple wholesale lenders, while a bank offers its own products and pricing. Compare equivalent written offers and consider both cost and execution.
Should I pay points to get a lower mortgage rate?
Paying points may make sense when the monthly savings recover the upfront cost before you expect to sell, refinance, or pay off the loan. Calculate the break even period before deciding.
How many mortgage lenders should I compare?
The CFPB recommends contacting at least three lenders. Compare quotes on the same day using the same loan terms, lock period, and points.
Is the lowest mortgage rate always the best mortgage?
No. A low rate may come with high discount points, higher mortgage insurance, unfavorable loan terms, or greater cash requirements. Compare the total cost and loan structure, not just the advertised rate.
When should I lock my mortgage rate?
Lock when the pricing supports your financial goals and the lock period safely covers the expected closing date. The correct decision depends on the transaction timeline, market conditions, and your ability to tolerate rate movement.
