What to look for when comparing mortgage offers
Comparing mortgage deals means looking at three things: the interest rate, the fees you pay upfront, and the total cost over the life of the loan. A lower interest rate does not always mean the best deal if the fees are much higher. You need to see the actual numbers from each lender so you can add them up the same way for each one.
The document that shows you these numbers is called the Loan Estimate. Federal law requires lenders to give you this form within three business days of your application. It lists the interest rate, the monthly payment, all upfront costs (origination fee, appraisal, title insurance, and others), and the total amount you will pay back. This is the document you use to compare one lender against another.
Do not rely on a phone quote or a rate sheet. Those numbers change daily and often leave out fees. The Loan Estimate is the only form that shows the complete picture, and lenders must use the same format, so you can line them up and see the differences.
Key Takeaways
- Request a Loan Estimate from each lender within three days of applying, and compare the same sections across all estimates side by side.
- The interest rate matters, but so do the upfront fees and the total amount you will repay over 15 or 30 years — calculate the full cost, not just the monthly payment.
- Lock your rate in writing once you find a deal you want, because rates can change daily and a verbal promise does not protect you.
- Compare offers from at least three lenders, including a bank, a credit union, and a mortgage broker, because rates and fees vary significantly.
- Watch for fees that can be negotiated (origination, discount points, appraisal) versus fees that are set by third parties (title insurance, property taxes).
The sections of the Loan Estimate to compare
The Loan Estimate has three pages. Page 1 shows the loan amount, interest rate, monthly payment, and the total amount you will pay back. This is where you see the big-picture cost. If one lender quotes 6.5% and another quotes 6.75%, the difference in your monthly payment and total repayment will be clear here.
Page 2 lists all the upfront costs. These include the origination fee (what the lender charges to process the loan), the appraisal fee (what it costs to value the property), title insurance (protects the lender if there is a problem with ownership), property taxes, homeowners insurance, and HOA fees if the property has one. Some of these fees are set by third parties and do not change much between lenders. Others — like the origination fee and appraisal — can be negotiated or waived.
Page 3 shows the closing disclosure timeline and any conditions the lender has placed on the loan. This is less about comparing and more about understanding what happens next, but read it anyway because it tells you when you need to lock your rate and when closing will happen.
How to calculate the true cost of each deal
The true cost is not the monthly payment. It is the total amount of money that leaves your pocket. To find this, add the loan amount plus all upfront fees, then subtract any credits the lender is offering. That number is what you actually pay the lender. Then multiply the monthly payment by the number of months (360 for a 30-year loan, 180 for a 15-year loan) to see the total interest and principal you will repay.
Example: Lender A offers a $300,000 loan at 6.5% with $5,000 in upfront fees. Your monthly payment is $1,896. Over 30 years, you will pay $682,560 total. Lender B offers the same $300,000 at 6.75% with $2,000 in upfront fees. Your monthly payment is $1,955. Over 30 years, you will pay $703,800 total. Lender B costs you $21,240 more, even though the monthly payment difference is only $59.
This calculation matters most if you plan to stay in the home for at least five years. If you think you will move or refinance sooner, the upfront fees matter more than the long-term interest cost, because you will not benefit from the lower rate for very long.
Rate locks and how they protect you
A rate lock is a written agreement that holds your interest rate steady for a set number of days, usually 30, 45, or 60 days. Rates move daily, sometimes multiple times a day. Without a lock, the rate you were quoted yesterday might be higher today. With a lock, the lender cannot raise your rate during the lock period, even if market rates go up.
Ask each lender for their rate lock terms in writing. Some lenders lock the rate for free for 30 days. Others charge a fee to lock for longer periods. A longer lock (60 days instead of 30) costs more but gives you more time to close if there are delays with the appraisal or title search. A shorter lock is cheaper but riskier if closing takes longer than expected.
Do not lock your rate until you have decided which lender you want to use. Once you lock, you are committed to that lender, and switching costs you the lock fee or forces you to start over with a new rate. Lock only after you have compared at least three offers and chosen the one with the lowest total cost.
Where to get offers from multiple lenders
You should compare offers from at least three different types of lenders: a traditional bank, a credit union (if you are a member), and a mortgage broker. Banks and credit unions are direct lenders — they use their own money to fund your loan. Mortgage brokers are intermediaries — they shop your application to multiple lenders and pass along the best offer. Each type often has different rates and fees.
Banks include national chains like Chase, Bank of America, and Wells Fargo, as well as regional banks in your area. Credit unions often offer lower rates to members, but you have to be a member to borrow. Mortgage brokers can be found through the National Association of Mortgage Brokers website or through a local referral. Do not use a broker who charges you an upfront fee before you see any offers — legitimate brokers are paid by the lender, not by you.
You can also compare online lenders like Better.com, Rocket Mortgage, or LendingTree. These lenders often have lower overhead costs and can offer competitive rates, but they may have stricter requirements or less flexibility if something goes wrong during the process. Get a Loan Estimate from each one and compare them the same way.
Fees you can negotiate versus fees you cannot
Some fees are set by the lender and can be negotiated. The origination fee (usually 0.5% to 1% of the loan amount) is the most common one. You can ask the lender to lower it, waive it, or offer you a lower rate in exchange for paying it. The appraisal fee (usually $400 to $700) can sometimes be waived if you are a repeat customer or if you have a large down payment. Discount points — where you pay money upfront to lower your interest rate — are entirely optional and worth considering only if you plan to stay in the home for many years.
Other fees are set by third parties and do not change much between lenders. Title insurance protects the lender (and you, if you pay for owner's insurance) against problems with the property's ownership history. The cost varies by state and by the property value, but you cannot shop around for a better price — it is regulated. Property taxes and homeowners insurance are not lender fees at all; they are your own costs that the lender estimates and collects in escrow.
When you negotiate, focus on the origination fee and the interest rate. Ask the lender: "Can you lower the origination fee, or would you rather lower the rate?" Often they will do one or the other. Do not waste time negotiating a $50 appraisal fee when the origination fee is $3,000.
Comparing fixed-rate and adjustable-rate mortgages
A fixed-rate mortgage has the same interest rate for the entire loan — 15 years or 30 years. Your monthly payment never changes. An adjustable-rate mortgage (ARM) starts with a lower rate for a set period (usually 3, 5, 7, or 10 years), then adjusts up or down based on market rates for the rest of the loan. After the adjustment period, your payment can go up significantly.
When comparing a fixed-rate offer to an ARM offer, look at the rate during the initial period only. A 5/1 ARM at 5.5% for the first five years might look cheaper than a 30-year fixed at 6.5%, but after five years, the ARM rate could jump to 7% or higher, and your payment could increase by $200 or more per month. Use the Loan Estimate to see what the payment would be after the adjustment period, or ask the lender to calculate it for you.
Fixed-rate mortgages are simpler to compare and easier to budget for. ARMs are worth considering only if you are certain you will move or refinance before the adjustment period ends, or if you can afford the payment at the highest possible rate (usually capped at 10% or 11%, depending on the loan type).
Frequently Asked Questions
How many lenders should I compare before choosing one?
Compare at least three lenders. This usually takes a few days and gives you a real sense of the market. Comparing more than five or six lenders does not usually change the outcome much, and each application creates a small dent in your credit score that fades after 45 days. Stick to three to five solid offers.
Does shopping around for rates hurt my credit score?
Multiple mortgage inquiries within 45 days count as a single inquiry on your credit report, so shopping around does not hurt you as long as you do it within that window. After 45 days, each new inquiry counts separately. Get all your Loan Estimates within two weeks to be safe.
What if two lenders have the same rate but different fees?
Choose the one with the lower total cost over the life of the loan. If you are staying in the home for 30 years, the lower upfront fees matter less than the interest rate. If you might move in five years, the upfront fees matter more. Calculate the total cost for your specific timeline, not just the monthly payment.
Can I negotiate the interest rate itself, or just the fees?
You can negotiate both. Rates are set by the market and the lender's pricing, but lenders have some flexibility, especially if you have a strong credit score, a large down payment, or if you are willing to pay points. Ask directly: "Is there any room to move on the rate?" The worst they can say is no.
What happens if rates drop after I lock?
You are locked in at your rate, so you cannot take advantage of the drop. Some lenders offer a "float down" option that lets you lower your rate once if rates drop during the lock period, but this usually costs a fee. Read your lock agreement carefully to see if this option is available and what it costs.
