How long do you have to compare Loan Estimates?
Short answer: more time than the pressure suggests, and there is a real rule protecting you that most answers online miss.
The 10 business day rule. A lender must stand behind the costs on your Loan Estimate for 10 business days. If you tell them you intend to proceed within that window, the origination charges listed become subject to strict tolerance rules and generally cannot increase at closing. After 10 business days, the lender may revise the offer. This rule is federal, it applies to every Loan Estimate, and it means an estimate in your hand is a standing offer, not a snapshot.
The 3 business day rule. Any lender you apply with must send you a Loan Estimate within 3 business days of your application. Collecting two or three competing estimates is a same week project, not a month long one.
The rate is separate. The interest rate on an unlocked estimate can move with the market every day. Check the Rate Lock box near the top of page 1: YES means your pricing is set through the listed date, NO means the rate floats until you lock. Fees hold for 10 business days; an unlocked rate does not.
Credit inquiries. Mortgage inquiries made within a short shopping window are commonly counted as one inquiry by scoring models, typically cited as 14 to 45 days depending on the model. Shopping several lenders in the same two weeks is the standard, score conscious way to do it.
If your closing date is tight, compress the sequence rather than skipping it: applications with two or three lenders on day one, estimates in hand by day three or four, decision inside the week.
Common questions
Can my Loan Estimate change after I receive it?
Origination charges are held to tolerance rules once you indicate intent to proceed in the 10 business day window. Estimates for third party services and prepaids can change as real bills replace estimates, within defined tolerances.
Is it too late to switch lenders after signing intent to proceed?
Intent to proceed is not a commitment to close with that lender. Switching remains legal until final documents are signed, though switching close to your closing date can cost time and require redisclosure.
Do I have to shop around at all?
No. But the public record shows wide fee ranges for identical loan types, and a competing estimate is the strongest negotiating instrument that exists.
