## Who this is for
Salaried homeowners with 3-8 years of equity in a starter property who are ready to purchase a larger home, typically managing the timing gap between sale proceeds and new purchase closing.

## Summary
A move-up transaction involves three interlocking mechanics: extracting equity from the departing property, bridging the timing gap between sale and purchase closings, and requalifying under B-20 stress-test rules on a materially larger mortgage balance. Each step has its own lender-policy variation and cost structure. Getting the sequencing wrong — particularly on bridge-loan availability and qualification timing — is the most common reason move-up transactions stall or collapse.

## Worked example
A salaried couple in Ontario earns $185,000 combined gross. Their starter home is under firm sale at $820,000 with a $310,000 mortgage balance outstanding, generating net equity of approximately $470,000 after real estate commissions (~$41,000) and discharge costs (~$3,500). They are purchasing a larger home at $1,250,000 with a 30-day gap between their sale closing (June 15) and purchase closing (July 15). They intend to put $400,000 down and carry a $850,000 uninsured mortgage.

- Net equity after sale costs: ~$470,000 (sale $820k minus $310k balance, $41k commissions, $3.5k discharge)
- New mortgage (uninsured, 25-yr am): $850,000 at ~5.10% 5-yr fixed = ~$5,020/mo P&I
- Bridge loan (30-day gap): $400,000 bridged at prime + 2% (~6.75%) = ~$2,250 interest cost for 30 days
- Stress-test qualifying rate: 7.10% (contract 5.10% + 2.00%) — TDS must stay ≤44%
- TDS at stress-test rate: ~41.8% on $185k gross — qualifies, but limited buffer

## Framework
### Equity extraction: what you actually net from the sale
Gross equity is the sale price minus the outstanding mortgage balance. Net equity — the figure that matters — subtracts real estate commissions (typically 3.5–5% in most Canadian markets), mortgage discharge or prepayment penalty, legal fees on the sale side (~$1,200–$1,800), and any outstanding HELOC balance secured against the property. If the departing mortgage is mid-term fixed, the IRD penalty can be material: on a $310,000 balance with 18 months remaining at a major bank, IRD can reach $4,000–$9,000 depending on posted-rate spread. **Run the penalty calculation before listing.** Some lenders will port the existing mortgage to the new property to eliminate the penalty — see the portability section below.

### Bridge financing: mechanics, availability, and cost
Bridge financing covers the period when you own both properties simultaneously — your purchase has closed but your sale has not yet funded. Most Schedule I banks and credit unions offer bridge loans, but only when **both** a firm sale agreement and a firm purchase agreement are in place. No firm sale = no bridge at most prime lenders; this is a hard policy line, not a negotiating point.

Bridge loan pricing is typically prime + 1.5% to prime + 3.0% (prime currently ~4.95% as of Q2 2026), plus a flat administration fee of $200–$500. On a $400,000 bridge for 30 days at prime + 2%, the all-in interest cost is roughly $2,200–$2,500 — modest relative to the transaction size. Bridges beyond 90 days become harder to place and more expensive; if your sale is conditional or your closing gap is wide, alternative lenders or private bridge lenders may be required at meaningfully higher rates (8–11%).

### Requalification under B-20: the stress test on a larger balance
The move-up buyer must requalify on the new, larger mortgage as a fresh origination. Under OSFI Guideline B-20, the qualifying rate is the greater of the contract rate plus 200 bps or 5.25% — at current 5-year fixed rates of 5.00–5.25%, the effective stress-test rate is 7.00–7.25%.

The critical shift from the starter-home qualification: **the departing mortgage payment is removed from TDS only once the sale is firm and the lender has confirmed the closing date.** Until then, some lenders carry both mortgage payments in TDS, which can temporarily push ratios above the 44% ceiling. Provide your lender with the firm sale agreement as early as possible. GDS ceiling is 39%, TDS ceiling is 44% under standard insured/uninsured guidelines, though some lenders apply tighter internal caps on high-balance uninsured files.

### Portability: eliminating the penalty by carrying the existing mortgage forward
If the departing mortgage is mid-term and carries a meaningful IRD penalty, porting it to the new property can save thousands. Most closed fixed-rate mortgages are portable, but the lender must approve the new property and the borrower must requalify on the blended balance. The ported amount carries the existing rate; the top-up (the incremental borrowing) is priced at current rates, blended together.

**Blend-and-extend** is a variant where the lender resets the term on the combined balance at a blended rate. The math favours porting when the penalty exceeds the rate differential savings over the remaining term. Not all lenders allow port-and-increase to uninsured territory if the original mortgage was insured — confirm this before assuming portability solves the penalty problem.

### The $1.5M insured cap and its effect on move-up buyers
The December 2024 reform raised the insured mortgage cap from $1.0M to $1.5M and extended 30-year amortizations to all insured borrowers (not just first-time buyers). For move-up buyers purchasing between $1.0M and $1.5M, this opens the insured route for the first time — minimum 10% down on the full purchase price, CMHC premium of 3.10% on the insured portion, but access to lower insured rates (typically 15–25 bps below uninsured equivalents).

For a $1,250,000 purchase with 10% down ($125,000), the insured mortgage is $1,125,000 plus a CMHC premium of ~$34,875 (3.10%), totalling ~$1,159,875. Compare this to an uninsured mortgage at 20% down ($250,000) on $1,000,000 — the insured route preserves $125,000 in cash but adds ~$35k to the mortgage balance. The break-even depends on what that $125k would otherwise earn and the rate differential.

### Closing cost stack on the purchase side
Move-up buyers often underestimate the purchase-side closing costs because they are focused on the equity math. In Ontario, land transfer tax on a $1,250,000 purchase is approximately $22,950 provincial (no first-time rebate available to move-up buyers) plus $22,950 Toronto municipal LTT if purchasing in Toronto — a combined $45,900 in LTT alone. Add legal fees ($1,800–$2,500), title insurance (~$400), home inspection ($500–$700), and moving costs. Budget 1.5–2.5% of purchase price for closing costs exclusive of the down payment. In BC, PTT on $1,250,000 is approximately $23,000. These costs must come from liquid funds — they cannot be rolled into the mortgage.

## Key considerations
- Sequence matters: get a firm sale before you firm up a purchase if at all possible. A conditional sale leaves you without bridge financing access at prime lenders and forces you into private bridge territory at 8–11%.
- The IRD penalty calculation should be requested from your lender in writing before you list your home — not after you have a firm sale. Penalties on 5-year fixed mortgages at major banks can reach 3–4 months of interest or the full IRD, whichever is greater, and the spread between your contract rate and the posted rate drives the number.
- If your combined household income has grown materially since your starter-home purchase, requalification on the larger mortgage may be straightforward — but if income is flat and the new mortgage is 2× the old one, TDS compression at stress-test rates is the binding constraint, not the down payment.
- Property tax on the new home will be higher than on the starter home and is included in GDS. Obtain the current tax bill for the target property before running your ratio math — a $1.25M home in Toronto may carry $8,000–$12,000 in annual property tax, adding ~$700–$1,000/month to GDS.
- If you are carrying a HELOC on the departing property, the full authorized limit (not just the drawn balance) is counted as a liability in TDS at most prime lenders. Close or reduce the HELOC limit before applying for the new mortgage if TDS is tight.

## Common mistakes
- Assuming the bridge loan is automatic once you have a purchase agreement — without a firm sale in hand, most prime lenders will not issue a bridge commitment, leaving the buyer scrambling for private financing at 9–11% days before closing.
- Forgetting to account for the IRD penalty in the equity calculation — a $15,000 penalty on a mid-term fixed mortgage reduces the effective down payment by the same amount and can push the LTV above the intended threshold.
- Running TDS ratios with the departing mortgage removed before the sale is firm — lenders will carry both payments until closing is confirmed, and a buyer who qualifies on paper with one mortgage may fail the ratio test when both are counted simultaneously.
- Underestimating land transfer tax as a closing cost — in Ontario and BC, LTT on a $1.25M purchase is $20,000–$45,000 depending on municipality, and this must come from liquid funds on closing day, not from the bridge or the mortgage.
- Porting a mortgage without confirming the lender will allow a port-and-increase to an uninsured balance — some lenders restrict porting to the same or lower LTV tier, meaning an insured-to-uninsured port is declined and the penalty applies anyway.

## Action steps
1. Request a mortgage penalty calculation from your current lender in writing — ask for both the 3-month interest figure and the IRD figure so you know the worst case before listing.
2. Run your TDS ratio at the stress-test rate (contract rate + 2.00%) using the new mortgage payment, property tax on the target property, and any remaining consumer debt — before you make an offer, not after.
3. Confirm with your broker whether the new purchase qualifies for insured financing under the post-December 2024 $1.5M cap rules, and model both the insured (lower rate, CMHC premium) and uninsured (higher rate, no premium) scenarios over your expected hold period.
4. Obtain a bridge financing pre-commitment from your lender at the same time as your mortgage pre-approval — confirm the maximum bridge amount, the rate, the administration fee, and the documentation required (firm sale agreement).
5. Budget 1.5–2.5% of the purchase price for closing costs on the buy side, separate from your down payment — land transfer tax, legal fees, title insurance, and adjustments must be liquid on closing day.
6. If your sale and purchase closings are more than 60 days apart, discuss with your broker whether a private bridge lender is needed and get a rate quote in advance rather than on an emergency basis.
