The 3-7-3 Rule in Mortgage Lending
If you’re shopping for a mortgage, you may hear about the “3-7-3 Rule.” It’s not a loan program or a type of mortgage. Instead, it’s a federal disclosure timeline designed to protect you as a borrower and make sure you have enough time to review important information before you commit.
What is the 3-7-3 Rule?
The 3-7-3 Rule comes from the Truth in Lending Act (TILA) and lays out three important timing requirements during the mortgage process:
3 Days – Initial Disclosures
Within 3 business days of your completed loan application, your lender must provide initial disclosures.
This includes the Loan Estimate (LE), which outlines your estimated loan terms, interest rate, closing costs, and monthly payment breakdown.
7 Days – Review Period
You must receive the Loan Estimate at least 7 business days before closing.
This gives you a full week to review the numbers, ask questions, and compare offers.
3 Days – Waiting Period After APR Changes
If the Annual Percentage Rate (APR) changes by more than 1/8% (0.125%) on a fixed-rate loan or 1/4% (0.25%) on an adjustable-rate loan, your lender must issue a new disclosure.
You then get another 3 business days to review the updated terms before closing.
Why Does the 3-7-3 Rule Matter?
The rule was created to protect consumers from last-minute surprises at the closing table. Before these requirements, it wasn’t uncommon for buyers to see new fees or loan terms just hours before signing papers.
With the 3-7-3 Rule in place, you get:
Time to review loan terms without pressure
Protection from bait-and-switch tactics
Clarity about closing costs before committing
Example: How It Plays Out
Let’s say you apply for a mortgage on Monday:
By Thursday (3 business days later), you must receive your Loan Estimate.
Your closing can’t happen until at least the following Tuesday (7 business days after the disclosure).
If your APR changes significantly, closing would be delayed another 3 business days to give you time to review.
Key Takeaways for Homebuyers
The 3-7-3 Rule isn’t red tape—it’s protection for you.
It ensures your lender is transparent and gives you time to make informed decisions.
If you ever feel rushed, remember: the law guarantees you this review period.
