Loan Estimate Explained (Part 1): How to Read Your LE and the Locked vs. Unlocked Difference
When you apply for a mortgage, federal law requires your lender or broker to provide you with a Loan Estimate (LE) within three business days of receiving your application. This three-page document is one of the most important pieces of paper you will receive during the homebuying process — yet most consumers never fully understand what they are looking at. This is Part 1 of our two-part guide. Here we explain what each section of the Loan Estimate means and — most critically — the difference between a locked and an unlocked LE that can cost you thousands of dollars.

What is a Loan Estimate and What Does It Include?
A Loan Estimate is a standardized three-page form issued under the TILA-RESPA Integrated Disclosure (TRID) rules. Every lender and mortgage broker is legally required to use the exact same format, making it straightforward to compare offers side by side. Understanding each section is essential before you commit to any loan program.
Page 1 — Loan Terms and Projected Payments
Loan Terms Box
Page 1 shows your loan amount, interest rate, monthly principal and interest payment, and whether these figures can increase after closing. Look specifically at the "Can this amount increase after closing?" column next to the interest rate. If it says YES — your rate is not locked, and you are looking at an estimate, not a guarantee.
The Full "Projected Payments" Block — The Most Important Box on the LE
The Projected Payments table is arguably the most important section of the entire Loan Estimate, yet it is the one most commonly misrepresented. A fully transparent, correctly filled-out Projected Payments block must include ALL of the following five components every single month:
- Principal & Interest (P&I) — the base loan repayment covering your balance reduction and the lender's interest charge.
- Mortgage Insurance (PMI/MIP) — required if your down payment is below 20% on a conventional loan, or mandatory for the life of an FHA loan. This can be $100–$400/month or more and must NOT be omitted.
- Estimated Escrow (Property Taxes + Homeowner's Insurance) — collected monthly and held in an escrow account. On a $400,000 home in Pennsylvania, this alone can be $600–$900/month.
- Flood Insurance — mandatory if the property is in a FEMA flood zone, ranging from $100 to $400/month. It must appear in the Projected Payments section.
- HOA / Condo Association Dues — if the property has mandatory association fees, these are listed separately but are part of your total monthly housing obligation and are factored into your DTI ratio.
The bottom line of the Projected Payments table is your true PITI payment — Principal, Interest, Taxes, and Insurance. If a loan officer shows you only the P&I line and calls it "your payment," they are giving you an incomplete — and potentially misleading — picture of your actual monthly obligation.
Pages 2 & 3 — Closing Costs, Government Fees, and the APR
Page 2 — Closing Costs by Section (A through H)
Page 2 labels every closing cost by section: Section A (origination charges and lender fees), Section B (services you cannot shop for — appraisal, credit report), Section C (services you CAN shop for — title insurance, attorney, settlement), Section E (government recording fees and transfer taxes), Section F (prepaid items — prepaid interest, insurance premium), Section G (initial escrow deposit), and Section H (other). We cover the critical consumer traps in Sections E and G in detail in Part 2.
Page 3 — APR and Total Interest Paid
Page 3 shows the Annual Percentage Rate (APR) — the true cost of the loan including all fees, not just the interest rate. It also shows the Total Interest Paid over the full loan term. A lower interest rate does not always mean a better deal if the lender charges significantly higher origination fees. Always compare the APR, not just the rate, when evaluating competing Loan Estimates.
Locked vs. Unlocked Loan Estimate: The Critical Difference
This is the most misunderstood concept in the entire mortgage process — and failing to understand it can cost you thousands of dollars.
What is an Unlocked Loan Estimate?
An unlocked Loan Estimate is issued when you first apply for a mortgage and the interest rate has not yet been locked with the lender. The rate shown is a market estimate — it reflects current conditions at the time of application but is NOT guaranteed. If mortgage rates rise between your application and the day you lock your rate, your actual monthly payment will be higher than what the unlocked LE showed.
Some loan officers use an unlocked LE to show you an artificially attractive rate, knowing that by the time you are ready to lock, rates may have moved. This bait-and-switch technique is one of the most common consumer complaints in the mortgage industry.
What is a Locked Loan Estimate?
A locked Loan Estimate is issued after you have formally locked your interest rate with the lender for a specific period — typically 30, 45, or 60 days. Once locked, the rate shown on the LE is contractually guaranteed as long as the loan closes before the lock expiration date. The locked LE is the document you should use to make your final lender comparison.
Key rule: Always ask for a locked LE before making your final lender decision. If a loan officer refuses or discourages you from locking, treat that as a serious warning sign.
How to Tell the Difference at a Glance
On the top of Page 1 of your Loan Estimate, locate the "Rate Lock" field. It will say either YES — Rate Lock until [date] or NO. Never accept a final loan offer based on an unlocked LE. Demand the locked version before signing any intent-to-proceed documents.
Your Rights as a Mortgage Consumer
Under federal law (RESPA and TILA), you have the right to receive a Loan Estimate within three business days of application. You are NOT obligated to proceed with any lender after receiving an LE. You can — and should — apply with multiple lenders and compare their locked Loan Estimates side by side. Rate shopping within a 14-to-45-day window is treated as a single credit inquiry for FICO scoring purposes, so there is no penalty for comparing offers from multiple licensed professionals.
Frequently Asked Questions — Part 1
Q: Is the Loan Estimate a commitment to lend?
A: No. A Loan Estimate is NOT a loan approval or a commitment to lend. It is a good-faith estimate of loan terms and costs. Final approval depends on underwriting, appraisal, and other conditions. Always consult with a licensed mortgage professional before making financial decisions.
Q: Can a lender change the numbers after issuing a Loan Estimate?
A: Some fees are subject to a "zero tolerance" rule and cannot increase at all (such as origination charges). Others can change by up to 10%, and some (like prepaid taxes based on actual tax bills) can change without limit. Ask your loan officer which category each fee falls into.
