How to Compare Two Mortgage Offers Side by Side
To compare two mortgage offers, look at page 2 of each Loan Estimate. Compare the interest rate, the origination charges (Section A), and the total closing costs. Then calculate the total cost of each loan over 5 years — rate plus fees. The lowest rate is not always the cheapest loan.
You got two Loan Estimates. Maybe three. The numbers look similar but different in confusing ways. One has a lower rate but higher fees. The other has a credit but a higher rate. You're staring at three pages of tiny boxes and you just want someone to tell you which one is cheaper.
I'm Adam Styer, mortgage broker, NMLS #513013. I compare Loan Estimates for borrowers every week. Here's exactly how to do it yourself — and why the lowest rate isn't always the winner.
What Is a Loan Estimate and Where Do I Find the Key Numbers?
A Loan Estimate is a standardized 3-page document that every lender is required to give you within 3 business days of receiving your application. The format is the same across every lender — that's by design, so you can compare them side by side.
Here's what matters on each page:
- Page 1 — your interest rate, monthly principal and interest payment, and estimated total closing costs. This is the summary page. It's useful for a quick glance but doesn't tell the whole story.
- Page 2 — the detailed fee breakdown. This is where the real comparison happens. Loan costs are split into sections: Section A (origination charges), Section B (services you cannot shop for), and Section C (services you can shop for). Then there are other costs in Sections E through H (taxes, prepaids, escrow).
- Page 3 — total cost projections over 5 years and the APR. This page does some of the math for you, but it makes assumptions about how long you keep the loan.
When you lay two Loan Estimates next to each other, page 2 is your battleground. That's where you see exactly what each lender is charging — and where the differences actually live.
Should I Compare Rate or APR?
This is one of the most common questions I get. The short answer: neither one by itself is enough.
The interest rate determines your monthly payment. It's the number most people focus on. But it doesn't account for the fees you're paying to get that rate.
The APR (Annual Percentage Rate) tries to solve that problem by spreading certain fees across the life of the loan and expressing the total cost as a single percentage. The idea is good. The execution is misleading.
Here's why: APR assumes you keep the loan for the full 30 years. Almost nobody does. The average mortgage lasts 5 to 7 years — people refinance, sell, or move. That means APR overstates the benefit of a low rate with high upfront costs and understates the benefit of a higher rate with low costs.
The better approach: calculate total interest paid plus total closing costs over your expected holding period — usually 5 years. That gives you the true cost of each offer in real dollars. For a deeper dive, see our guide on APR vs. interest rate.
What Fees Should I Actually Compare?
Not all fees on a Loan Estimate are created equal. Some vary by lender. Some don't. Knowing the difference saves you from comparing the wrong things.
Section A — Origination Charges: This is the lender's profit. It includes the loan origination fee, discount points, and any processing or underwriting fees. This section is where the real difference between two offers lives. If Lender A charges $2,000 in origination and Lender B charges $5,000, that's a $3,000 difference that directly affects the cost of your loan.
Sections B and C — Third-Party Services: Appraisal, credit report, title insurance, title search, settlement fees. These costs are largely the same no matter which lender you choose — they're set by the third-party providers, not the lender. Small variations here usually don't move the needle.
Sections E through H — Taxes, Prepaids, Escrow: These are government fees, homeowners insurance premiums, prepaid interest, and initial escrow deposits. They're the same regardless of lender. Don't let a higher number in these sections scare you off a lender — it's not their fee.
Bottom line: compare Section A aggressively. Glance at Sections B and C. Ignore E through H when choosing between lenders.
What About Points and Lender Credits?
Points and credits are two sides of the same coin. They're how lenders let you trade between upfront costs and monthly costs.
Discount points buy down your interest rate. One point = 1% of the loan amount. On a $400,000 loan, one point costs $4,000 upfront and typically lowers your rate by about 0.25%. You pay more at closing but save every month for as long as you have the loan.
Lender credits work the opposite way. The lender gives you money toward closing costs, and in exchange, your rate goes up. You pay less at closing but more each month.
Neither is inherently better. It depends on one thing: how long you keep the loan.
- If you're staying 7+ years, paying points often makes sense — you have enough monthly savings to recoup the upfront cost.
- If you're selling or refinancing in 2-3 years, take the lender credit — you won't be around long enough for the lower rate to pay off.
- If you're not sure, the middle ground (no points, no credits) is usually fine.
When comparing two Loan Estimates, make sure you understand whether either offer includes points or credits. It's listed in Section A on page 2. A lower rate doesn't mean a better deal if the borrower is paying $8,000 in points to get it.
How Do I Calculate Which Loan Is Actually Cheaper?
Here's the math. It takes about 60 seconds per offer.
Step 1: Look at the monthly principal and interest payment on page 1. Multiply it by 60 (that's 5 years of payments). This gives you total payments over 5 years.
Step 2: Subtract the principal you'll have paid down. You can find this on page 3 under "In 5 Years" — it shows how much you'll have paid in principal. Subtract that from total payments. The remainder is your total interest cost over 5 years.
Step 3: Add total closing costs from page 2 (Sections A through C — the lender and third-party fees).
Total 5-year cost = Total interest over 5 years + Total closing costs (Sections A-C)
Let's run two scenarios on a $400,000 loan:
Offer A: 6.5% rate, $4,000 in total lender/third-party fees
- Monthly P&I: $2,528
- Total payments over 5 years: $151,680
- Principal paid in 5 years: ~$30,140
- Total interest over 5 years: ~$121,540
- Plus closing costs: $4,000
- Total 5-year cost: ~$125,540
Offer B: 6.375% rate, $8,000 in total lender/third-party fees
- Monthly P&I: $2,497
- Total payments over 5 years: $149,820
- Principal paid in 5 years: ~$31,540
- Total interest over 5 years: ~$118,280
- Plus closing costs: $8,000
- Total 5-year cost: ~$126,280
Offer A costs about $740 less over 5 years — despite having the higher rate. That's because the $4,000 in fee savings more than offsets the $31/month payment difference.
For a deeper look at this principle, read why the lowest rate isn't always the cheapest loan.
When the Lower Rate Actually Costs More
This happens more often than you'd think. Here's the pattern:
A big retail lender quotes you 6.375%. Looks great on paper. But buried in the Loan Estimate, they're charging $6,000 in origination fees plus 0.5 points ($2,000). That's $8,000 in lender costs before you even get to title and escrow.
A broker quotes you 6.5%. Higher rate. But origination is $1,500 and there are no points. Total lender costs: $1,500. Add the same title and escrow fees — $2,500 — and you're at $4,000 total.
That 0.125% rate difference saves you about $31 per month. Over 5 years, that's $1,860 in savings. But you paid $4,000 more in fees to get it. You don't break even until year 10. If you sell or refinance before then — and statistically, you will — the lower rate cost you money.
This is exactly why you can't just compare rates. You have to compare total cost over your expected timeline.
Frequently Asked Questions
Focus on three things: the interest rate on page 1, the origination charges in Section A on page 2 (this is the lender's profit and where the real difference between offers lives), and the total closing costs. Then calculate total cost over your expected holding period — usually 5 to 7 years — by adding total interest paid plus total fees. The loan with the lowest combined number is the cheaper loan, even if it doesn't have the lowest rate.
Neither one tells the full story by itself. The interest rate determines your monthly payment. APR spreads certain fees across the life of the loan to give you a blended cost — but it assumes you keep the loan for the full 30 years, which almost nobody does. The average mortgage lasts 5 to 7 years. A better approach: calculate total interest plus total closing costs over your expected holding period. That gives you the true cost of each offer.
Add up the total interest you'll pay over 5 years plus the total closing costs for each offer. The lower total wins. For example, a 6.5% rate with $4,000 in fees on a $400,000 loan costs about $125,540 over 5 years. A 6.375% rate with $8,000 in fees costs about $126,280. The higher rate is actually $740 cheaper because the fee savings more than offset the rate difference. Always run the math — don't just compare rates.
