## Who this is for
Salaried buyers and real estate investors who purchased a property with cash — either to win a competitive offer or deploy capital quickly — and now want to extract equity through a mortgage or refinance.

## Summary
Mortgaging a property you already own outright is structurally a refinance in Canada, not a purchase — and that distinction carries significant LTV, stress-test, and lender-policy consequences. Most federally regulated lenders cap refinances at 80% LTV regardless of how recently you purchased, and a meaningful subset treat any refi within 12 months of a cash purchase as a de facto purchase transaction, applying purchase-LTV logic and requiring full re-underwriting. The path to maximum proceeds depends on timing, lender selection, and whether you're willing to accept a conventional uninsured product or route through a non-bank lender.

## Worked example
An investor purchases a detached property in Hamilton for $850,000 cash in January 2026 — no conditions, no financing, competitive offer wins. Six months later, they want to pull equity to fund a second acquisition. The property appraises at $870,000. They want to know how much they can extract and at what cost.

- Maximum refinance LTV (federally regulated lender): 80% of $870,000 = $696,000
- Proceeds available (net of zero existing mortgage): Up to $696,000 gross, subject to stress-test qualification
- Stress-test qualifying rate (2026): Contract rate + 2%, or 5.25% floor — whichever is higher
- Approximate 5-year fixed rate on uninsured refi: ~5.0–5.4% (contract); qualifying at ~7.0–7.4%
- 12-month lender policy risk: Several A-lenders restrict proceeds to original purchase price within first 12 months

## Framework
### Why a cash purchase followed by a mortgage is always a refinance
Under OSFI Guideline B-20 and standard lender policy, the mortgage product type is determined at the time of application — not at the time of purchase. Once title transfers without a mortgage, the property is unencumbered, and any subsequent financing is classified as a refinance. This matters because insured mortgages (CMHC, Sagen, Canada Guaranty) are categorically unavailable on refinances — the maximum insured LTV of 95% applies only to purchase transactions. The practical ceiling on a refinance is 80% LTV, and that ceiling is set by federal regulation under the Protection of Residential Mortgage or Hypothecary Insurance Act, not lender discretion. No amount of creditworthiness or reserves moves that ceiling at a federally regulated financial institution.

### The 12-month rule — lender policy, not federal regulation
OSFI B-20 does not itself impose a 12-month seasoning requirement, but a significant number of Schedule I and Schedule II banks have adopted internal policies that treat a refinance within 12 months of a cash purchase as a purchase-equivalent transaction. The practical effect: proceeds are capped at the lesser of 80% of current appraised value **or** 80% of the original purchase price. For a property that has appreciated, this is a meaningful constraint. Lender policies vary — some apply the cap for 6 months, others for 12, and a handful of monolines and credit unions have no seasoning restriction at all. A broker with a wide lender panel is the most efficient way to identify which institutions will use current appraised value from day one.

### Stress-test mechanics on a delayed financing application
The B-20 stress test applies in full to all refinances at federally regulated lenders, with no exemption for borrowers who previously owned the property free and clear. The qualifying rate is the greater of the contract rate plus 200 basis points or 5.25% (the Minimum Qualifying Rate as of 2026). At a contract rate of 5.20% on a 5-year fixed, the qualifying rate is 7.20%. On a $696,000 mortgage with a 25-year amortization, the monthly payment at 7.20% is approximately $4,960 — that figure must fit within a TDS ratio of 44% (or 42% GDS) against the borrower's gross income. An investor with rental income from the subject property can include 50–80% of gross rents (lender-dependent) to support TDS, which meaningfully improves qualification headroom.

### Alternative lender routes when A-lender policy is restrictive
Borrowers who need proceeds above what an A-lender will advance within the first 12 months — or who cannot pass the stress test at full proceeds — have two structural alternatives:

**1. B-lenders (Equitable Bank, Home Trust, Haventree, MCAP alternative division).** These lenders are federally regulated but apply more flexible seasoning and income-qualification policies. Rates run 50–120 bps above prime A-lender pricing. The 80% LTV ceiling still applies.

**2. Private / MIC lenders.** No stress test, no seasoning requirement, LTV up to 75–80% on residential. Rates typically 8.5–11% with 1–2% lender fees. Appropriate as a 12–18 month bridge until the property seasons and the borrower can refinance into an A or B product. Exit strategy must be underwritten before entry.

### HELOC as a partial alternative
A HELOC on a property owned free and clear is subject to the same 80% combined LTV ceiling as a refinance, but the revolving structure offers flexibility that a term mortgage does not — draw only what you need, repay, redraw. OSFI B-20 requires full stress-test qualification on HELOC approvals at federally regulated lenders. The HELOC-only ceiling is 65% LTV (the readvanceable portion of a combined mortgage + HELOC product can reach 80% total, but the standalone HELOC is capped at 65%). For an investor who wants a revolving facility rather than a lump-sum term mortgage, a readvanceable product — a term mortgage up to 80% LTV with an embedded HELOC growing as principal is repaid — is often the most capital-efficient structure.

### Tax and documentation considerations for investors
For investors, the interest on a mortgage placed on a property that generates rental income is generally deductible under the Income Tax Act, provided the borrowed funds are used for income-producing purposes. If the mortgage proceeds are used to purchase a second investment property, the interest traces to that second property — not the subject property — for deductibility purposes. The CRA's tracing rules require clear documentation of fund flow. Investors should retain a paper trail from mortgage advance through to deployment of capital. Additionally, if the original cash purchase was made through a corporation, the mortgage application will be underwritten as a commercial or investor file, with different LTV and income-qualification standards than a personal residential application.

## Key considerations
- Appraisal timing matters significantly. If the market has moved since your cash purchase, ordering an appraisal before approaching lenders gives you a defensible current-value baseline. Some lenders will use the purchase price as the value floor within 12 months regardless of appraisal — confirm the policy before paying for the appraisal.
- Amortization on a refinance is capped at 25 years for insured mortgages — but since refinances are uninsured by definition, the practical amortization ceiling at most A-lenders is 30 years, which meaningfully reduces the monthly payment used in TDS calculations and can be the difference between qualifying and not.
- If you are an investor using a corporation to hold the property, the mortgage will be underwritten under commercial residential guidelines. LTV ceilings, rate premiums, and documentation requirements differ materially from personal residential files — expect 65–75% LTV and a rate premium of 30–80 bps.
- Source-of-funds documentation for the original cash purchase will be required by the new lender. Expect to produce bank statements, wire transfer records, or investment account redemption confirmations showing the origin of the purchase funds — particularly if the purchase was recent.
- Prepayment penalties do not apply on a cash-purchased property (there is no existing mortgage to break), but the new mortgage you place will carry its own penalty structure. Negotiate prepayment privileges carefully if you anticipate selling or refinancing again within the term.

## Common mistakes
- Assuming the lender will use current appraised value within the first 12 months — several major banks cap proceeds at the original purchase price during this window, which can reduce available equity by tens of thousands of dollars on an appreciating asset.
- Applying directly to a single bank branch without shopping lender policy on seasoning — branch-level underwriters often apply the most conservative internal policy interpretation, and the spread across lenders on this specific issue is large enough to materially change the outcome.
- Ignoring the stress test when projecting how much equity is accessible — the 80% LTV ceiling is a gross maximum, but the actual advance is also constrained by income-based TDS limits. Borrowers who plan around $696,000 available and qualify for $520,000 face a capital shortfall in their acquisition plan.
- Using mortgage proceeds for a purpose that breaks the interest-deductibility chain — investors who pull equity from a rental property and use it for personal consumption cannot deduct the interest, even if the subject property is income-producing. The CRA traces use of funds, not source of funds.
- Placing a private mortgage without a documented exit strategy — private rates of 9–11% are sustainable for 12–18 months but erode returns rapidly. Borrowers who enter private financing without a clear path to A or B refinancing often find themselves trapped when the term expires.

## Action steps
1. Confirm the purchase date and calculate whether you are inside or outside the 12-month window — this single variable determines which lenders will use current appraised value versus purchase price, and should drive your lender shortlist.
2. Order a current appraisal from an AACI-designated appraiser before submitting applications, particularly if the market has moved since your purchase. A defensible appraisal gives you negotiating leverage with lenders who have discretion on value.
3. Run your TDS ratio at the stress-test qualifying rate (contract rate + 2%, minimum 5.25%) against your verified gross income and any rental income from the subject property — this tells you whether the LTV ceiling or the income ceiling is your binding constraint.
4. Engage a broker with access to both A-lender and B-lender panels, and specifically ask each lender about their seasoning policy on cash purchases. Document the policy in writing before proceeding.
5. If you are an investor, consult a tax advisor on fund-flow documentation before the mortgage closes — the interest deductibility of the new mortgage depends on how proceeds are deployed, and the paper trail must be established at the time of advance, not reconstructed later.
6. If the A-lender proceeds are insufficient for your acquisition timeline, model the B-lender or private bridge scenario explicitly: calculate the all-in cost (rate + fees + legal) over the expected bridge period and compare it against the opportunity cost of waiting 12 months for full A-lender access.
