Pre-Approval vs Approval: The Difference That Costs Fraser Valley Buyers Their Deposit

A pre-approval is not an approval. It's a snapshot of what a lender thinks they could lend you today, based on what you've told them — which is a useful planning number and a dangerous offer-day number. Almost every spring we get the call from a buyer who wrote on a townhouse believing the bank's pre-approval letter was a guarantee. It isn't, and the gap between what it says and what it actually does is where deposits go to die.

This page is the FRIVE team's plain-English read on the difference between pre-approval and approval in BC — what each one actually commits the lender to, where they fall apart, and how to upgrade your file from one to the other before you write on a Fraser Valley condo or townhouse.

Quick comparison

	Pre-approval	Full approval
What it covers	Your income, debts, and credit — as stated	Specific property + verified income + appraisal
Income verification	Often self-reported (varies by lender)	Documented — T4s, pay stubs, NOAs
Property-specific	No	Yes
Appraisal required	No	Yes
Strata docs reviewed	No	Yes (for condos/townhouses)
Binding commitment	No	Yes — lender commits to fund
Rate hold	Typically 90–120 days	Tied to the accepted offer

Scenario	What to do
Browsing / 6–12 months from buying	Get a soft pre-approval — useful for budgeting
1–3 months from writing an offer	Upgrade to a documented pre-approval (hand over T4s, pay stubs, NOA)
Writing on a condo or townhouse	Include a financing condition of at least 5 business days
Self-employed or commission income	Document pre-approval is essential — don't write until income is verified
Pre-approval is over 90 days old	Refresh it before shopping — rate hold may be expired

What a pre-approval actually is

A mortgage pre-approval is the lender's best estimate of how much they could lend you, based on the income, debt, and credit information you've supplied. It typically includes:

• A hard credit pull, so your credit score and reported debts are confirmed
• A stated income figure (you tell them; they may or may not ask for documents)
• A rough debt profile (you tell them; they don't yet have your full bank statements)
• A rate hold — usually 90 to 120 days — that protects the rate quoted if rates rise during the period
• A maximum mortgage amount and a maximum purchase price the lender thinks fits

What it does not include is verification against a specific property. It also doesn't necessarily include verification against your actual income documents — many bank-branch pre-approvals are issued without ever seeing a T4 or a Notice of Assessment. The lender has trusted what you told them, and they've put a soft commitment on paper based on that.

The Financial Consumer Agency of Canada describes a pre-approval as a tool to estimate the maximum mortgage you may qualify for — not a guarantee that the lender will fund a specific deal. That distinction matters when you're sitting at a kitchen table writing an offer.

What a full approval actually is

A full approval — sometimes called a "firm commitment" or "lender commitment" — is property-specific. It exists only after the lender has been given the actual deal: the property address, the purchase price, the accepted contract of purchase and sale, and (for stratas) the strata documents the seller is required to provide.

To convert the pre-approval into a full approval, the lender typically needs:

• An appraisal of the property, ordered by the lender (or accepted from a third party), to confirm the property is worth at least the purchase price
• Verified income documents — current T4s, two recent pay stubs, the most recent Notice of Assessment, and confirmation of employment for salaried buyers; two years of NOAs and business financials for self-employed buyers
• Confirmation of down payment — bank statements showing the funds for 90 days, plus a gift letter if any portion is gifted family money, or FHSA / HBP / TFSA withdrawal statements
• Strata documents for a condo or townhouse — the depreciation report, contingency reserve fund statement, minutes from the last two years of meetings, the Form B information certificate, and (when relevant) special levy resolutions

Only after that work is done does the lender issue a written commitment to fund a specific mortgage against a specific property. That commitment is what your real estate lawyer or notary relies on to close the deal.

Where pre-approvals fall apart

We've watched every one of these scenarios kill a Fraser Valley deal in the last twelve months. Each is more common than buyers expect.

The appraisal comes in low. The lender will only lend against the lower of the purchase price or the appraised value. If you offered $720,000 on a Willoughby townhouse and it appraises at $695,000, the lender shrinks the mortgage and you cover the $25,000 gap in cash. If you don't have the cash, the deal collapses.

Verified income is lower than what you reported. Most bank-branch pre-approvals don't verify income up front. When the file goes to underwriting and the actual T4s show a base salary lower than the all-in number you mentioned (which included variable bonus, overtime, or commission that doesn't fully count), the qualifying number drops. We've seen $700K pre-approvals shrink to $620K when commission income wasn't fully reckoned.

Strata documents reveal a problem. A pending special levy. A contingency reserve fund that's a fraction of what the depreciation report recommends. An active legal claim against the strata. Any of these can make a lender refuse to fund — or fund only with a smaller mortgage that forces a price renegotiation or a deal-collapse.

Your credit or debt has changed. Between pre-approval and offer, a new car loan, a missed payment, a co-signed line for a family member, or even a hard credit pull from another lender can shift your ratios. The lender re-checks at full approval; your file may no longer fit.

The property type itself isn't acceptable. Some lenders won't fund mortgages on properties under 600 square feet, on leasehold land, on age-restricted strata buildings, or on properties with rental restrictions the lender views as unfavourable. The pre-approval didn't ask. The full approval does.

We dig into the strata side of this on the strata documents review page and on the special levies page. The lender will read those documents whether you do or not.

What changes the answer

The gap between pre-approval and full approval matters more for some buyers than others. The decision drivers we use to assess how much pre-approval cushion a buyer actually has:

Income type. T4 salary employees with two-plus years at the same employer have the cleanest files. Self-employed buyers, commission earners, and recent job-changers are more likely to see qualifying income shrink between pre-approval and approval. If that's you, push your broker or bank for a documented pre-approval — one where they've actually reviewed your T4s, NOAs, and pay stubs — before you write.

Down payment source. Gifted funds, FHSA withdrawals, and HBP withdrawals all need paperwork the lender will demand at approval. If any meaningful portion of your down payment is gifted or coming from a registered account, sort the documents now, not the day after the offer is accepted.

Property type. Detached homes with a recent appraisal nearby are easier than 1960s wood-frame condos with deferred maintenance, leasehold townhomes, or anything with a known special-levy history. The strata side is where pre-approvals most often fall down — particularly on older buildings.

Time between pre-approval and offer. A pre-approval written six weeks before you wrote an offer is still warm. A pre-approval written four months ago — past the rate hold — is essentially expired. The credit pull is stale, your bonus cheques might have moved, the lender's policy may have shifted. Refresh before you shop.

Whether you've done the income verification work already. Most of the gap between pre-approval and approval is income verification. If you've already handed the lender your T4s, NOAs, and pay stubs at the pre-approval stage and they've underwritten the income side, the remaining work at full approval is just the property — which is much faster and much less likely to surprise you.

Common mistakes we see

Treating the pre-approval letter as a shopping budget. The letter says $720K. The lender means "we think we could go to $720K, under the assumptions we don't yet verify." Most of the buyers we see who land well shop 10 to 15 percent under their pre-approval ceiling, which leaves room for the qualifying-rate change, the appraisal coming in soft, or a strata document surprise.

Writing subject-free offers off a pre-approval. Every spring we see at least one first-time buyer in Willoughby or Surrey try to compete on a multi-offer townhouse by dropping the financing condition. The pre-approval becomes a coin flip on appraisal and strata documents. If either comes in differently than the lender expected, the buyer is the one holding a non-refundable deposit and a deal they can't fund.

Letting the pre-approval expire without re-doing it. Rate holds typically run 90 to 120 days. Past that, the rate is no longer protected, and the lender's policy on what counts as qualifying income may have shifted. We've had buyers find out two days before writing that their pre-approval lapsed three weeks ago.

Not telling the lender about a credit change. A new car payment, a co-signed line for a sibling, a missed payment on a credit card you forgot about — any of these can change your ratios. If something material has changed since pre-approval, tell the lender before you write, not after.

Trusting one bank's number without shopping it. A bank-branch pre-approval is one lender's read. The same file at a mortgage broker — see our broker vs bank page — sometimes comes back with a meaningfully different number, because the lender pool and the qualifying flexibility differ. Get two quotes before you commit to a shopping ceiling.

Forgetting the qualifying-rate math. Every pre-approval is stress-tested at the greater of 5.25% or the contract rate plus 2 percentage points. With contract rates around 4.5% in May 2026, that means qualifying at roughly 6.5%. The number the pre-approval shows already has the stress test baked in — but if your rate moves at offer time, the qualifying number moves with it. The math doesn't sit still, and the GDS and TDS ratios are what catches most first-time buyers when it shifts.

How to upgrade a pre-approval before you shop

The best Fraser Valley files we see in spring 2026 went through a deliberate upgrade between pre-approval and offer. The order:

1. Get a soft pre-approval with your broker or bank — usually a 30-minute conversation, a credit pull, and a number on paper. Use that to calibrate your search.
2. Within the first two weeks, hand over full documentation — most recent two pay stubs, last two T4s, the most recent Notice of Assessment, current statements for every account where your down payment is sitting (90-day history), and any gift-letter paperwork.
3. Have the broker or bank underwrite the income side — re-issue the pre-approval with a note that confirms the income is documented. Most lenders will do this; some will not, in which case the broker shops it to one that does.
4. Get the rate hold confirmed in writing with the expiry date. Calendar the date.
5. When you write an offer, write a financing condition of at least five business days so the lender has time to order the appraisal, review the strata documents, and convert the documented pre-approval into a full approval.

That sequence is what closes the gap. It doesn't eliminate the appraisal risk or the strata-document risk — nothing does, on a specific property, until the lender has both in front of them. But it eliminates the income surprise that takes a lot of first-time buyers down at the wire.

Where this fits in the bigger picture

Pre-approval is the planning number that anchors the rest of the affordability decisions. Read the pillar page for the full affordability map — how the qualifying income, down payment, ratios, and reserves fit together. The GDS and TDS page explains the two ceilings the lender actually checks; the broker vs bank page explains where to get the strongest version of the pre-approval; the fixed vs variable page and the insured vs uninsured page cover the rate-and-structure choices that flow from the pre-approval number.

If the property side is what worries you most — older buildings, special levies, contingency reserve funds — the strata documents checklist and the strata special levies page are the next reads.
