How to Compare Loan Estimates
The Loan Estimate is the one mortgage document built to be compared. Federal rules (TRID) force every lender onto the same three-page form with the numbers in the same boxes — so two quotes really are apples-to-apples, if you know which boxes to read. Most people read the wrong one.
The three-page map
Page 1 is the summary: loan amount, rate, monthly payment, and — bottom right — the Estimated Cash to Close. Page 2 is the itemized costs, split into the fees you can shop and the ones you can't. Page 3 has the APR and a "Comparisons" box. The headline rate lives on page 1, but the deal is decided on page 2.
The one rule that makes them comparable
Get every Loan Estimate on the same day at the same rate. Rates move daily, so a quote from Tuesday and one from Thursday aren't comparable at all — you'd be measuring the market's move, not the lender. Ask each lender to quote the same note rate (or the same par rate), then the only thing left to differ is their fees. That's the whole point of the exercise.
Where lenders actually differ: Section A
On page 2, Section A — Origination Charges is the lender's own price: its origination fee and any discount points. This is the number to interrogate, because it's the part the lender controls. Sections B and C (appraisal, title, recording) are third-party costs that barely move between lenders. If one Estimate shows a suspiciously low rate, check Section A — the rate was probably bought down with points hiding there.
Don't optimize the wrong number
Cash to Close is tempting to minimize, but it folds in your down payment and prepaids — money that's yours either way, not a lender cost. A lender credit can shrink cash to close while raising your rate for 30 years. Compare the cost of the loan (Section A + points, net of credits) against the APR — not the cash number the sales pitch points at.
When your rate is locked and finalized, the Closing Disclosure restates these same boxes — compare the two line by line, and question anything that moved. Shop against a neutral reference: our par-based Index shows where the market actually is, and the free calculator turns each quote into a monthly number.
