The Loan Estimate gives a mortgage comparison a common format. Its value comes from comparing the same transaction, then explaining the differences line by line.
Use the actual documents from LMCU and any other lender you are considering, not a screenshot of an advertised rate. An estimate reflects assumptions, a date and a particular loan. Keep the original files privately. This publication has no upload function and does not need your application documents.
Check the identity of the comparison
Begin by matching the loan amount, term, product, loan type, property and intended use. Check whether each rate is locked and the relevant dates. If one form describes a different loan, ask whether the lender can provide a comparable version. A useful annotation is “different product,” not immediately “more expensive lender.”
Also compare the dates the offers were issued. Prices can move between them. A document that was competitive earlier is not a promise that its pricing is available today.
Read costs in groups
The CFPB recommends looking closely at origination charges, services the borrower cannot shop for and lender credits when comparing lender-controlled costs. Other amounts, including property taxes and insurance, deserve accuracy checks but are not evidence of a lender discount. Mark both categories on your own worksheet so they do not drift into one undifferentiated total.
Ask for an explanation of unfamiliar line items rather than assuming two differently named fees provide different services. Conversely, do not conclude that one missing label means there is no cost anywhere else. The written totals and the lender’s explanation should reconcile.
Use the five-year section with care
The comparison section shows a five-year total paid and principal paid down. Subtracting the principal figure from the total identifies the interest-and-fee component for that period. This is one way to compare borrowing costs, not a prediction that you will move after five years or a measure of all ownership expenses.
Fictional arithmetic
If a form showed $120,000 paid and $25,000 of principal paid down, the difference would be $95,000. If another showed $119,000 and $23,000, the difference would be $96,000. The smaller total paid is not automatically the smaller borrowing cost. These are invented figures, not completed Loan Estimates or market quotes.
A shorter or longer intended holding period can change the usefulness of the comparison. For an adjustable-rate loan, do not treat a calculation based on an unchanged rate as a ceiling on future costs. Read the rate-structure guide as well.
Keep cash to close on its own line
Cash to close asks how much money must be available for settlement after the listed adjustments. It is different from the lifetime or five-year borrowing cost. Check how deposits, credits, down payment and prepaids flow into it. A smaller cash requirement can be valuable, but it may come with a trade-off elsewhere in the loan.
Build a difference log before choosing a winner
Give every meaningful difference one of three labels: a changed loan choice, a changed estimate, or an unexplained charge. A different term belongs in the first group. A different allowance for insurance belongs in the second. A fee that you cannot identify belongs in the third until the lender explains it. This sorting prevents a total from becoming a verdict before you know what produced it.
For each line, record both amounts and the next useful action. You might request a matched term, obtain a property-specific quote, or ask whether two labels describe the same service. Close an item only when the answer reconciles the figures. “That is standard” does not explain why an amount differs between these particular offers.
Give upfront costs a realistic time horizon
Imagine two otherwise matched fictional offers. One requires $2,400 more upfront and reduces principal and interest by $60 a month. Dividing $2,400 by $60 gives 40 months of payment reductions to equal that initial difference. That is a narrow cash-flow screen, not a complete loan valuation. It does not account for remaining principal balances, the value of keeping cash available, or other differences in the documents.
Now ask what happens if the household keeps the loan for 24 months, 48 months, or much longer. The first period produces $1,440 of payment reductions; the second produces $2,880. These invented amounts show why an upfront choice can look different under different plans. They do not establish whether paying points is right for any borrower.
If the two loans do not have the same structure, stop using this shortcut as if they did. Request the balances and payment schedules needed for a fuller comparison. A lower payment created partly by slower principal repayment is a different proposition from a lower payment on an otherwise matched loan.
Finally, preserve a clean copy of the comparison you actually used. Keep later revisions separately with a short explanation of what changed. A reliable record helps you distinguish a deliberate choice from a number that quietly changed while the transaction moved forward.
Turn each difference into one written question
For each unexplained difference, record the page, label, amount and question. For example: “These offers use different insurance estimates. What property-specific information supports each one?” Ask the lender to explain material changes and retain the response. Before settlement, use the Closing Disclosure review to compare the final figures with the relevant estimate. A well-organized question list is more useful than a ranking built from uncertain assumptions.
