- • Smart Fixed: Lower rate with 10% prepayment privileges (vs. 20% on standard)
- • Prepayment privileges (standard): 20% lump sum + 20% payment increase
- • IRD methodology: Posted-rate based
- • Signature product: BMO Homeowner ReadiLine (combined mortgage + HELOC)
BMO's Charge Types: Standard vs. ReadiLine
BMO's standalone residential mortgages use a standard charge registration, which keeps switching costs modest ($300-$700 in legal fees, often covered by new-lender cash-back). The BMO Homeowner ReadiLine — BMO's combined mortgage and HELOC product — is a collateral charge, with the same switching friction as TD's collateral mortgages (~$700-$1,500 in legal fees).
Before shopping, confirm which BMO product you're on. Customers on standalone BMO mortgages enjoy easy switching; ReadiLine customers face higher switching costs but have access to re-advanceable HELOC credit during the term.
BMO Smart Fixed vs. Standard Fixed
BMO uniquely offers two variants of the 5-year fixed mortgage, and choosing between them at renewal requires understanding your prepayment intentions:
| Feature | BMO Standard Fixed | BMO Smart Fixed |
|---|---|---|
| Rate (April 2026) | ~4.51% | ~4.34% (typically 10-20 bps lower) |
| Lump-sum prepayment | Up to 20%/year | Up to 10%/year |
| Payment increase | Up to 20% | Up to 10% |
| Best for | Borrowers who prepay aggressively | Borrowers with steady payments only |
Rule of thumb: if you anticipate making lump-sum prepayments exceeding 10% of original principal, the standard fixed's higher rate is typically still cheaper than the Smart Fixed's lower rate plus penalty-rate prepayments. Run the specific numbers with your broker.
BMO Prepayment Privileges — Best in the Big 6
The standard BMO 5-year fixed offers the most generous prepayment privileges in the Big 6:
- Lump-sum prepayments: Up to 20% of original principal per year, without penalty. On a $500K mortgage, that's $100K/year in prepayment capacity.
- Payment increase: You can increase your regular payment by up to 20% without penalty.
- Flexibility: Prepayments can be made on any regular payment date.
These privileges tie or beat most competitors: TD allows 15% + 100% payment increase; RBC 10% + Double-Up; First National 15% + 15%. BMO's 20%/20% is best-in-class for active prepayers.
BMO's IRD Methodology
BMO uses a posted-rate IRD methodology identical in approach to RBC, TD, and most Big 6 peers. The comparison rate is BMO's posted rate for the remaining term, less the discount you received at origination. This produces higher IRD penalties than monoline contract-rate methodology.
At renewal (maturity), no IRD applies. If you plan to break mid-term (selling, refinancing), a lender with fairer IRD (First National, some credit unions) saves money.
The BMO Renewal Negotiation Playbook
-
1. Identify your current product
Confirm whether you're on standard BMO fixed, Smart Fixed, or ReadiLine. This determines your switching cost and baseline features.
-
2. Get broker quotes
Benchmark BMO's renewal offer against monolines (First National, MCAP), credit unions, and competing banks. Target a 15-25 bps rate improvement.
-
3. Call BMO mortgage retention with a competing quote
BMO's retention desk has real rate authority and typically matches or comes close to concrete broker quotes.
-
4. Weigh prepayment privileges in your decision
If you actively prepay, BMO's standard-fixed 20% privilege is a real feature worth paying for. If a monoline offers a lower rate but only 15% prepayment, run the specific math.
-
5. Sign before maturity
Always actively sign. BMO's auto-renewal is priced less favorably than the negotiated offer.
