The short answer
To compare two Loan Estimates: (1) confirm both are for the same loan type, term, and loan amount; (2) compare Section A (origination charges) line by line — these are the lender's own fees and the main thing that differs; (3) compare the interest rate, APR, monthly payment, and cash to close; (4) factor in lender credits (Section J) which reduce your cash to close but usually mean a higher rate. The cheapest loan is the one with the lowest total cost over the time you'll actually keep it — not the one with the lowest rate alone.
Step 1: Make sure you're comparing apples to apples
Before comparing a single number, verify these match on both estimates:
- Loan type (conventional, FHA, VA) — top of page 1
- Loan term (30-year fixed, 15-year fixed, 5/1 ARM) — top of page 1
- Loan amount — if one lender assumed 10% down and another assumed 20%, nothing else is comparable
- Rate lock status — a locked rate vs. a floating estimate aren't directly comparable
- Property address — same property, same purpose (purchase vs. refinance)
If any of these differ, ask the lender to re-quote on matching terms. Comparing a 30-year fixed to a 5/1 ARM tells you nothing useful.
Step 2: Compare Section A — where lenders actually compete
Page 2 of the Loan Estimate breaks costs into sections. Section A (Origination Charges) is the lender's own fees: origination fee, application fee, underwriting fee, discount points. This is the primary place lenders differ, because Sections B–H are mostly third-party costs (appraisal, title, government fees) that are similar regardless of lender.
Line up Section A from both estimates. A lender charging $1,500 in origination fees vs. one charging $300 is a real $1,200 difference — same loan, same day.
Step 3: Compare the rate, APR, and monthly payment (page 1)
- Interest rate — the rate used to calculate your payment
- APR — the broader cost measure including most fees, expressed as a yearly rate. Useful for comparing, but imperfect: it assumes you keep the loan the full term
- Monthly principal & interest — what you'll actually pay each month
A lower rate with higher fees can cost more than a slightly higher rate with zero fees — which is why you can't stop at the rate.
Step 4: Account for lender credits (Section J)
Lender credits reduce your cash to close but always come with a tradeoff — typically a higher interest rate. A $2,000 lender credit isn't free money; you're paying for it over the life of the loan through a higher rate. Calculate the break-even: how long until the higher monthly payment wipes out the upfront credit?
Step 5: Compare cash to close (page 1, bottom)
"Cash to Close" is the total you'll need at closing: down payment + closing costs − lender credits − deposits. This is your bottom line for closing day. But don't confuse a lower cash-to-close with a cheaper loan — a lender can reduce cash to close by raising your rate (via credits) while increasing your total cost.
Step 6: Compare total cost over YOUR time horizon
The Loan Estimate shows "In 5 Years" totals on page 1: total paid, principal paid, and costs. But 5 years is arbitrary. If you'll sell or refinance in 3 years, compare 3-year costs. If this is a 10-year home, compare 10-year costs. Our comparison tool calculates this for any horizon.
Common mistakes
- Comparing only the interest rate. A 6.5% rate with $4,000 in fees vs. 6.625% with $500 in fees — the "higher" rate is cheaper for most horizons.
- Ignoring Section A differences. Third-party fees (Sections B+) are largely the same everywhere. Section A is where the lender's pricing lives.
- Treating lender credits as free. They're priced into your rate.
- Comparing estimates from different days. Rates move daily. Get all estimates on the same day for a valid comparison.
- Forgetting the rate lock. An unlocked estimate can change. Confirm lock status and expiration.
Methodology and limitations
Loan Estimates are standardized by the Consumer Financial Protection Bureau (CFPB); every lender uses the same form, which is what makes comparison possible. However: lenders' underlying assumptions (credit score, property type, occupancy) affect pricing — verify the assumptions on page 1 match your situation. Estimates are not guarantees; final costs appear on the Closing Disclosure. Rate data referenced is as of October 2026.
