Pre-Qualification — What It Actually Is

A pre-qualification is an estimate of what you might qualify for, based on numbers you tell the lender — no verification, no credit check, no documents. Many online calculators and bank websites offer this.

Why pre-qualification isn't enough in Calgary's market:

A pre-qualification letter from a bank or online calculator means a lender ran numbers you told them — without checking any of it. Sellers and their agents know this. It signals you're an early-stage buyer, not a qualified one.

Pre-Approval — What It Actually Is

A pre-approval means a lender has reviewed your actual documents, verified your income, checked your credit, and issued a conditional commitment to lend up to a specified amount at a held rate.

  • Your income is confirmed — not estimated
  • Your credit is checked and factored in
  • A specific rate is held for 120 days
  • You know your real budget — not an estimate
  • Sellers take you seriously as a qualified buyer

The Rate Hold — A Pre-Approval Benefit Most Buyers Miss

What a rate hold means:

If rates rise between your pre-approval and closing day, you keep the lower rate. If rates fall, your broker shops again for the lower rate. The hold protects you with no downside.

Typical rate hold period: 120 days from pre-approval date.

When Pre-Approval Becomes Full Approval

A pre-approval is conditional — it doesn't guarantee the mortgage. Full (final) approval happens after:

  • Your offer on a specific property is accepted
  • The property appraises at or above the purchase price
  • No material changes to your financial situation since pre-approval
  • Lender confirms all conditions (typically 5–10 business days)

What Can Change Between Pre-Approval and Final Approval

This is where buyers sometimes get tripped up. Between pre-approval and closing, avoid:

  • Changing jobs or going self-employed
  • Taking on new debt (car loan, credit card, line of credit)
  • Making large cash withdrawals that can't be explained
  • Missing any payments on existing accounts
  • Co-signing on anyone else's loan
