Mortgage Pre-Approval vs. Mortgage Approval: What’s the Difference?

If you're looking to buy a home, you've likely heard that you need to get 'pre-approved' for a mortgage. But what does that really mean, and how is it different from a full mortgage approval? Understanding this distinction is crucial for a smooth and successful home purchase.

Many buyers mistakenly think a pre-approval guarantees their financing. In reality, it's just the first important step. Let's break down the key differences.

Mortgage Pre-Approval: Your Buying Power Estimate

A pre-approval is an initial evaluation by a lender or mortgage broker based on the financial information you provide. It’s a critical first step that tells you how much you can likely borrow.

What it involves:

  • A credit check

  • Review of your income, assets, and debts

  • An estimated purchase price and loan amount

What you get:

  • A pre-approval certificate or letter

  • An interest rate hold (typically 90-120 days)

  • A clear budget for your home search

The key limitation: A pre-approval is not a guaranteed loan. It's based on unverified information and doesn't consider the property you'll eventually purchase. I had a client who had pre approval from one of the big banks. He made an offer on old house without subject to finance, and bank would not approve the property. Client had to get private mortgage to purchase this property.  

Mortgage Approval: The Final Green Light

A full mortgage approval (also called final approval or financing commitment) comes after you've found a property and signed a purchase agreement. This is the comprehensive underwriting process where the lender verifies everything and approves the specific property.

What it involves:

  • Verification of all your documentation (income, down payment, etc.)

  • A professional appraisal of the property

  • Review of the purchase agreement

  • Property title search and insurance requirements

What you get:

  • A firm commitment from the lender to fund your mortgage

  • Final interest rate and terms

  • The confidence to proceed to closing

Why Both Matter in Your Home Buying Journey

Think of it this way:

  • Pre-approval = Permission to shop

  • Final approval = Permission to buy

The pre-approval gets you in the game and shows sellers you're a serious buyer. The final approval gets you across the finish line with the keys in hand.

The Gap Between Pre-Approval and Final Approval

Several factors can derail a mortgage between pre-approval and final approval:

  • Changes to your credit, job, or income

  • Issues with the property's value or condition

  • Unverifiable down payment sources

  • New debt taken on during the home search
