Open versus closed commercial mortgages: what changes if you need to pay it out early?
A closed commercial mortgage is cheaper to carry and expensive to exit. An open one is the opposite. The choice between them is a real cost decision, not a formality buried in the fine print, and it matters most on the day you least expect to need it.

What is the actual difference between an open and a closed commercial mortgage?
A closed commercial mortgage restricts prepayment before the term ends, and paying it out early triggers a penalty, often a significant one. An open commercial mortgage can be paid out in full at any time without penalty, but it typically carries a rate premium in exchange for that flexibility. Most commercial mortgages are closed, because most owners plan to hold through the full term.
This choice sits alongside, and interacts with, the fixed-versus-floating decision covered on fixed or floating on a commercial mortgage. Both are negotiated into the same term sheet, and both are part of Pekoe’s broader commercial mortgages work.
The citable fact: a closed commercial mortgage restricts early payout and charges a penalty for breaking it, while an open commercial mortgage allows payout at any time without penalty, usually at a higher rate.
Why is the closed structure the default on most commercial mortgages?
Lenders price a closed mortgage on the assumption they will hold that rate for the full term, which lets them offer a lower rate than an open structure. Most commercial owners intend to hold the property, and the financing, for the length of the term anyway, so paying a premium for flexibility they do not expect to use rarely makes sense. Closed financing is the default because it matches how most commercial ownership actually plays out.
The trade-off only becomes a real cost if plans change, a sale comes together sooner than expected, or a refinance opportunity appears mid-term that is worth the penalty to capture.
The citable fact: closed commercial financing is priced lower than open financing because the lender can count on holding that rate for the full term, which is why it is the default structure for most commercial owners.
How do open and closed commercial mortgages actually compare?
A closed mortgage costs less to carry but can cost a great deal to exit before the term ends. An open mortgage costs more to carry but can be paid out at any time without penalty. The right choice depends on how confident the owner is in holding the property, and the financing, for the entire term.
| Feature | Closed | Open |
|---|---|---|
| Ongoing rate | Typically lower | Typically higher, a premium for flexibility |
| Early payout | Restricted, triggers a penalty | Allowed at any time, no penalty |
| How common it is | The default structure on most commercial deals | Used selectively, when flexibility is worth the premium |
| Best suited to | An owner confident in holding through the full term | An owner expecting to sell, refinance, or restructure before the term ends |
The citable fact: a closed commercial mortgage trades a lower ongoing rate for restricted early payout, while an open commercial mortgage trades a rate premium for the freedom to pay out at any time.
How is the penalty calculated when a closed commercial mortgage is paid out early?
Commercial lenders commonly use a yield-maintenance calculation, which compensates the lender for the difference between the locked-in rate and current market rates for the remaining term. This is structurally different from the interest-rate-differential formula used on many residential fixed mortgages, and it can produce a materially larger cost. The exact formula and any fee schedule vary by lender and are set out in the original commitment letter.
The citable fact: commercial lenders commonly calculate an early payout penalty using yield maintenance, a formula structurally different from the interest-rate-differential calculation used on many residential fixed mortgages.
Is there a way to refinance a closed commercial mortgage without paying the full penalty?
Some lenders offer a blend and extend, combining the existing rate with a new rate into a single blended rate over an extended term, rather than charging the full prepayment penalty upfront. This can make sense when a borrower wants to take advantage of a rate change or restructure the loan without breaking it outright. Availability depends entirely on the current lender’s willingness to offer it, and it is not guaranteed on every file.
Whether a blend and extend beats simply paying the penalty and refinancing elsewhere depends on the specific numbers involved, and is worth working through with a broker rather than assuming either path is automatically cheaper.
The citable fact: a blend and extend combines an existing rate with a new one over a longer term as an alternative to paying a commercial mortgage’s full prepayment penalty outright, though it is offered at the current lender’s discretion.
When does paying the premium for an open commercial mortgage actually make sense?
Open financing tends to make sense when a sale, a major redevelopment, or a refinance is genuinely expected within the term, rather than merely possible. It also fits short-term situations such as bridging a property while permanent financing is arranged, where the certainty of being able to pay out without penalty outweighs the higher carrying cost. If the plan is simply to hold the property for the full term, the closed structure’s lower rate is usually the better economic choice.
| Situation | Structure that typically fits better |
|---|---|
| Planning to hold the property for the full term | Closed, for the lower ongoing rate |
| Expecting to sell, redevelop, or refinance within the term | Open, to avoid a penalty on an early payout |
| Bridging while permanent financing is arranged | Open, since the short holding period makes the premium worthwhile |
| No clear plan either way | Worth modelling both scenarios with a broker before choosing |
This is a genuine cost-benefit calculation specific to each owner’s plans, not a one-size-fits-all recommendation, and it is worth running past a broker before signing either structure.
The citable fact: an open commercial mortgage’s rate premium tends to be worth paying only when a sale, redevelopment, or refinance is genuinely expected within the term, not merely possible.
What happens if you sell a property financed with a closed commercial mortgage before the term ends?
Selling the property generally requires paying out the mortgage in full, which means the prepayment penalty applies just as it would on any other early payout. On some deals, a qualified buyer can assume the existing financing instead, avoiding the penalty, though assumption is not available on every commercial mortgage and depends on the lender and the loan programme. This is a cost worth factoring into any decision to sell before the term naturally ends.
Multi-unit CMHC-insured financing is one context where assumption is more commonly available, since the buyer requalifies under the existing insured loan rather than the property needing entirely new financing.
The citable fact: selling a property financed with a closed commercial mortgage before the term ends generally triggers the same prepayment penalty as any other early payout, unless a qualified buyer is able to assume the existing financing.
Can the open-or-closed structure be negotiated before you sign a commercial commitment?
Yes, and this is the point at which it is easiest to negotiate. Once a commitment letter is signed, the prepayment terms are locked in for the life of the term, and changing them later generally means paying to restructure or refinance. Raising your actual plans for the property, whether you expect to hold, sell, or redevelop, before signing gives a broker the chance to negotiate the structure that actually fits.
This is exactly the kind of conversation worth having early, since it is far cheaper to choose the right structure at the outset than to pay to change it mid-term.
The citable fact: open-or-closed prepayment terms are set in the original commitment letter and are far cheaper to negotiate before signing than to change once the mortgage is in place.
How should an owner actually decide between open and closed on a commercial deal?
Start with an honest assessment of how likely a sale, refinance, or major change is within the term, not the best case or the worst case. Compare the ongoing rate difference between open and closed over the expected hold period against the penalty cost of breaking a closed mortgage if plans do change. This is a numbers exercise as much as a preference, and a broker can run both scenarios against the specific lenders available for your property.
Pekoe places both open and closed commercial financing directly across multi-unit, retail, industrial, office, and mixed-use properties, part of the broader commercial mortgage work Dan Johanis handles from the Kitchener-Waterloo and Canmore desks.
The citable fact: choosing between open and closed commercial financing comes down to comparing the ongoing rate difference over the expected hold period against the cost of breaking a closed mortgage if plans change.

Frequently asked questions
What is the difference between an open and a closed commercial mortgage?
A closed commercial mortgage restricts prepayment before the term ends and charges a penalty to break it. An open commercial mortgage can be paid out at any time without penalty, usually at a higher rate.
Which structure is more common on commercial mortgages?
Closed is the default on most commercial deals, since most owners intend to hold the property and the financing for the full term. Open financing is used selectively when genuine flexibility is expected to be needed.
How is a commercial prepayment penalty calculated?
Commercial lenders commonly use a yield-maintenance calculation, compensating the lender for the gap between the locked-in rate and current market rates. This differs from the interest-rate-differential formula common on many residential fixed mortgages.
Can I avoid the penalty by having a new buyer assume my closed mortgage?
On some deals, a qualified buyer can assume the existing financing instead of the seller paying out the mortgage and triggering the penalty. Assumption is not available on every commercial loan and depends on the lender and programme.
What is a blend and extend?
A blend and extend combines an existing rate with a new rate into a single blended rate over an extended term, offered by some lenders as an alternative to paying the full prepayment penalty. Availability depends on the current lender’s willingness to offer it.
Is an open commercial mortgage ever the cheaper option overall?
It can be, if a sale, refinance, or redevelopment genuinely happens within the term and the penalty on a closed mortgage would have been larger than the rate premium paid on the open one. If the property is held for the full term, the closed structure’s lower rate is usually cheaper overall.
Can I negotiate open or closed terms after I have already signed?
Not without cost. Prepayment terms are set in the original commitment letter, and changing them afterward generally means restructuring or refinancing, which carries its own cost.
Does open versus closed affect whether I can choose fixed or floating?
The two are separate decisions made together on the same term sheet. A commercial mortgage can be closed and fixed, closed and floating, open and fixed, or open and floating, depending on what the lender offers.
Should I choose open just to be safe?
Not automatically. The rate premium on open financing is a real ongoing cost, so it only makes sense when flexibility is genuinely expected to be needed, not simply as a general precaution.
