How Do I Compare Two Loan Estimates and Tell Which One Is Actually Cheaper?

Compare the sections the lender actually sets — its origination charges, the services it selects, the rate, the points and any lender credit. The rest of a Loan Estimate is that lender's guess at bills you will pay to somebody else, and those bills are the same whoever you choose. The cheaper-looking total is often just the more optimistic guess.

Two estimates for the same house can differ by thousands on the front page and be within a few hundred dollars of each other on the only part either lender controls.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, NMLS #483943, through C2 Financial Corporation. I'm licensed in fourteen states, and this is the request I get most often from someone already holding paper: two forms, both official-looking, and no way to tell which one is the better loan.

Which numbers on the form did the lender actually choose?

The Loan Estimate is a standardized federal form. Its layout, section letters and the order of the lines are fixed by Regulation Z at 12 CFR 1026.37, which is why every lender's version looks identical. That sameness is the useful part: the third line of section A on one form means exactly what the third line of section A means on the other.

Page 2 splits into two halves, and the split is the whole comparison.

Loan Costs is the lender's half.

• Section A, origination charges. The lender's own price for making the loan. Points, origination fee, underwriting, application. This is where a lender's pricing decision physically appears on paper.
• Section B, services you cannot shop for. Real third-party work, but the lender picks the vendor: the appraisal, the credit report, the flood determination. The lender does not keep this money, and it does choose who gets it.
• Section C, services you can shop for. Title work, survey, pest inspection. The lender gives an estimate and a written list of providers, and you may use someone else.

Other Costs is everybody else's half.

• Section E, taxes and government fees. Recording charges and transfer taxes, set by the state and county where the house sits.
• Section F, prepaids. Your first insurance premium and the interest between closing and the first payment.
• Section G, initial escrow. The opening balance of your own escrow account.
• Section H, other. Owner's title insurance, and anything else the transaction requires.

Sections E through H are not the lender's price. They are that lender's estimate of bills attached to the house and to you. Buy the same house on the same day and those bills land at the same amount regardless of whose logo is at the top of the form. The mechanics of each bucket are laid out on the closing costs page; the point here is narrower, and it is that half the page is not a comparison at all.

Why the cash to close is the wrong number to compare

The number almost everyone compares is Estimated Cash to Close, because it is large, bolded and on page 1.

It is also the number most contaminated by guesswork. It carries the prepaids, the escrow opening balance and the taxes, so a lender that estimates your homeowner's insurance a few hundred dollars low and funds three months of taxes where the county will want eight produces a smaller headline figure without a single one of its own charges being cheaper.

Nobody has to be doing anything improper for this to happen. One lender might use a conservative default for escrows and another a thin one. Estimates of the same real bill differ honestly, and the variation between states is large enough that a national assumption is usually wrong in a predictable direction.

The consequence is worth stating plainly. Choosing on cash to close rewards whichever lender guessed lowest about money that was never theirs.

What the tolerance rules tell you about which numbers are real

Federal rule sorts the form for you, and this is the part most people holding two estimates have never been told.

Under the good-faith requirements at 12 CFR 1026.19(e)(3), the lines on a Loan Estimate fall into three groups by how much they are permitted to move between the estimate and the final Closing Disclosure.

Cannot increase at all. Section A origination charges, section B services you cannot shop for, and transfer taxes. If these rise, the lender generally has to cure the difference.

May rise, but only by ten percent in total. Section C services, when you use a provider from the lender's written list, together with recording fees. The test applies to the group, not to any single line.

May move freely, in good faith. Prepaids, the initial escrow deposit, property insurance, and any service you shop for using a provider who was not on the lender's list.

Read that as a map of what each number is. A figure the lender is not allowed to increase is a price it has committed to. A figure permitted to move is an estimate of somebody else's bill. Comparing prices to prices tells you which lender is cheaper. Comparing estimates to estimates tells you which lender is more optimistic, which is not a quality you are shopping for.

How to put two estimates on the same footing

Six steps, in order. This is the same sequence I run when a client emails me a competitor's form and asks what they are looking at.

1. Confirm both forms describe the same loan. Page 1: same loan amount, same product, same term, same escrow election, and the same answer in the rate-lock box. A locked quote and a floating one are not comparable, and neither are two different down payments.

2. Check the issue dates. Pricing moves daily. Two estimates from two different weeks compare two different markets, and the older one is a historical document. If they are more than a day or two apart, ask for a fresh one before doing anything else.

3. Add section A plus section B on each form. That subtotal is the lender-controlled, cannot-increase figure. Subtract any lender credit shown on page 2. Whichever number is smaller belongs to the lender charging less to make the loan.

4. Compare section C only against section C, and only when both are quoting from their own provider lists. If one form assumes you will use its title company and the other assumes you will bring your own, they are answering different questions.

5. Set sections E through H aside as a comparison, then use them as a check. They should not decide anything between two lenders. They are still worth reading, because a prepaid or escrow line far below what you know your insurance and taxes to be tells you the cash you actually need at the table is higher than the page says.

6. Confirm with page 3. The In 5 Years box, required by 12 CFR 1026.37(l), shows total dollars paid and principal retired over five years, which is closer to an apples-to-apples figure than anything on page 1. Sit it alongside the APR rather than trusting either alone. APR is a real measure with real blind spots, and it distorts most when the two offers carry different points.

If a step turns up a mismatch, the fix is one email: ask both lenders to price the same loan amount, the same product and the same lock period, on the same day, and reissue. That is a routine request. Any originator who takes it badly has told you something useful at no cost.

The mistakes that make the wrong offer look cheaper

Shopping the total. Comparing the two big page-1 numbers and stopping. It is the fastest way to pick the more optimistic estimator.

Rewarding the low guess. Treating a smaller escrow or insurance line as a saving. That money gets collected either way, and a thin escrow opening balance often means a payment adjustment later.

Ignoring the credit. A lender credit reduces closing costs and is paid for with a higher rate, so a form showing a large credit is showing a trade rather than a discount. The same lever runs the other way with points and buydowns.

Comparing across days. Rates and pricing change; two forms from two weeks apart cannot be compared, and the same movement is most of the reason a quoted rate can differ from an advertised one.

Assuming the shopping list is mandatory. Section C is shoppable by law. Using the lender's list keeps the ten percent group tolerance; going outside it removes that protection but can still cost less.

An illustration, so the arithmetic is visible

Numbers below are invented to show the mechanism, not a quote.

The same buyer, the same house, the same $400,000 loan, both forms issued the same morning, both locked.

Lender A

• Section A, origination charges: $3,900
• Section B, services you cannot shop for: $1,150
• Section C, services you can shop for: $2,150
• Sections E through H, taxes, prepaids, escrow and owner's title: $6,700
• Total closing costs: $13,900

Lender B

• Section A, origination charges: $5,200
• Section B, services you cannot shop for: $1,100
• Section C, services you can shop for: $2,100
• Sections E through H: $4,300
• Total closing costs: $12,700

Lender B looks $1,200 cheaper, and every buyer I have ever handed these to picks B.

Now run step 3. Lender A's section A plus section B is $5,050. Lender B's is $6,300. On the only part either lender sets, and the part neither is permitted to increase, Lender A is $1,250 cheaper.

The gap came from sections E through H, where B is $2,400 lighter. Reading those lines shows why: B funded three months of property taxes into the escrow account where A funded eight, and B carried an insurance premium several hundred dollars below the quote the buyer already had in hand. Neither number is B's to control, and both will be corrected before closing.

Correct them, and B's total goes to about $15,100 against A's $13,900. The offer that appeared to save $1,200 costs $1,200 more, and the entire reversal was sitting in two lines that were never a comparison between lenders.

What to do once you know which one is cheaper

Take the cheaper lender-controlled subtotal back to the other lender and ask them to match it. That request is normal, it is what the standardized form exists to make possible, and the worst outcome is that they decline. Nothing about asking obligates you, and moving to a different lender after a pre-approval stays available right up until you close.

If you would rather see where a competitive number actually sits before you make that call, run your own scenario — live pricing for your loan amount and your state, with no credit pull, no account and nobody calling you. Bring what you learn back to whichever forms are on your kitchen table.

Nothing here is a loan approval, a denial, a commitment to lend, or tax advice. Regulations and filed fee schedules change, and what applies to a specific transaction is worth confirming rather than assuming.

Common questions

What is the difference between a Loan Estimate and a pre-approval letter?

A pre-approval letter is a lender's opinion about a client's file, written for a seller to read. A Loan Estimate is a standardized federal disclosure about a specific loan on a specific property, issued within three business days of a completed application, and its charges carry legal limits on how far they may move. A letter costs the lender nothing to write. An estimate binds parts of its own pricing.

Can a lender change the fees on a Loan Estimate before closing?

Some of them, within limits. Origination charges, services the lender selected and transfer taxes generally cannot increase at all. Services shopped from the lender's own list, grouped with recording fees, may rise up to ten percent in total. Prepaids, the initial escrow deposit and insurance may move in good faith because they are estimates of outside bills. A valid changed circumstance, such as a different loan amount or a property issue, can reset those baselines, and the lender must reissue the form.

Do I have to use the title company my lender suggests?

No. Section C exists because those services are shoppable. Using a provider from the lender's written list keeps the ten percent group tolerance on those charges. Going outside the list removes that protection, and it can still be the cheaper choice. In several states custom or the sales contract already determines who selects the closing agent, so the practical answer varies by where the house is.

Is the lowest APR always the cheapest loan?

No. APR spreads certain financed costs across the full term, so it flatters a loan with high upfront points if you keep the mortgage for the whole thirty years and penalizes it if you sell or refinance in five. Two offers with the same APR can cost very different amounts over the period a client actually holds the loan. Read APR next to the In 5 Years box rather than on its own.

How many Loan Estimates should I get?

Two is enough to see the pattern and three is plenty. Requesting them close together matters more than requesting many, because pricing moves daily and estimates from different weeks are not comparable. Shopping several mortgage lenders inside a short window is also treated as a single event by the common credit scoring models, so comparing is not the thing that harms a credit score.

The two estimates are for different loan amounts. What now?

Stop and reissue rather than adjusting mentally. Section A frequently contains points priced as a percentage of the loan, so a different loan amount changes the lender's charge without the lender changing its pricing. Ask both for the same loan amount, the same product, the same term and the same lock period, dated the same day. Comparing anything else measures the difference between two scenarios rather than between two lenders.
