Investors in private mortgages think in positions, and they are right to. Position is the single largest determinant of both the yield you are offered and the loss you absorb if something goes wrong. Yet the investor-side comparison is poorly served: there is abundant material explaining first and second mortgages to borrowers, and very little tracing what each position actually receives when a file goes bad.
This article does that arithmetic.
What position means legally
When a mortgage is registered against title, its priority is generally determined by the order of registration. A first mortgage is paid out of sale proceeds before a second receives anything. A second receives only what is left. Nothing about that order is negotiable once it is registered, which is why a postponement agreement — where an existing lender agrees to rank behind a new one — is a document rather than a courtesy.
The practical consequence is that a first mortgage and a second mortgage against the same property, at the same moment, with the same borrower, are different investments. They share a borrower and a building, and almost nothing else.
Why a second pays more
It pays more because it loses first. In a shortfall, the second absorbs the entire loss before the first absorbs any. That is the whole explanation, and any yield premium on a second should be understood as the price of standing at the back of the queue rather than as a reward for diligence or relationship.
A worked recovery
Take a property appraised at $800,000 with a $560,000 first and a $80,000 second — a 70% first and an 80% combined ratio. The borrower defaults. Three scenarios, with illustrative costs.
| Market holds | Market falls 15% | Market falls 25% | |
|---|---|---|---|
| Sale price | $800,000 | $680,000 | $600,000 |
| Less selling costs and legal, say 6% | ($48,000) | ($40,800) | ($36,000) |
| Less accrued interest, taxes, insurance and carrying, say 8 months | ($45,000) | ($45,000) | ($45,000) |
| Net proceeds available | $707,000 | $594,200 | $519,000 |
| First mortgage recovers | $560,000 — in full | $560,000 — in full | $519,000 — short $41,000 |
| Second mortgage recovers | $80,000 — in full | $34,200 — short $45,800 | nil |
Read the middle column carefully, because it is the one that matters. The market fell 15%. The first mortgage was repaid in full and its investor felt nothing. The second lost 57% of its principal. The property did not have to collapse, and the borrower did not have to be fraudulent. A routine correction plus eight months of carrying costs was enough.
In the third column the first is also impaired — which is the reminder that a first charge is safer, not safe.
Where enforcement happens changes the answer
The arithmetic above assumes eight months of carrying costs. That assumption is doing a great deal of work, and it varies by province in ways most investor material ignores entirely.
- Ontario, New Brunswick, Newfoundland and Labrador, and Prince Edward Island are power-of-sale jurisdictions. A lender can, following statutory notice, sell the property without a court action. That is generally faster, which means fewer months of accrued carrying costs eroding the proceeds.
- British Columbia, Alberta, Saskatchewan and Nova Scotia run court-supervised processes. A judicial sale takes longer, and the extra months of interest, taxes and insurance come out of the same pot that was going to repay you.
- Quebec does not fit the binary at all. Enforcement runs through hypothecary recourses under the Civil Code, with a mandatory prior notice period, and the procedure cannot be varied or waived in advance.
- Saskatchewan additionally requires leave of the court before enforcement proceeds, and recourse to a borrower's personal covenant is frequently unavailable. Alberta restricts suing an individual borrower on the personal covenant, though corporate borrowers face full enforcement.
For a second mortgage, every additional month of delay is a direct transfer from your recovery to the carrying account. A second charge in a slow-enforcement province on a slow-selling property is a materially different risk from the same position in a fast one, and the yield offered does not always reflect it.
When each position makes sense
| First mortgage | Second mortgage | |
|---|---|---|
| Recovers | First, in full, before anything else | Only after the first is paid in full |
| Yield | Lower | Higher — the premium is the price of the queue position |
| Loss behaviour | Impaired only after the cushion and the second are exhausted | Absorbs the first dollar of shortfall |
| Sensitivity to delay | Moderate | High — carrying costs erode the residual that would repay you |
| What to scrutinise most | Marketability and the appraisal basis | The balance ahead, the combined ratio, and the enforcement jurisdiction |
Neither position is better. A first charge buys you resilience and pays you less for it. A second charge pays you more and asks you to accept that a moderate market move can take most of your principal. Both are legitimate; what is not legitimate is being offered the second while the risk is described as though it were the first.
A second mortgage does not pay more because someone was generous. It pays more because it loses first, and a fifteen per cent market move plus eight months of carrying costs is enough to prove it.
Questions investors ask
What happens to a second mortgage in a power of sale?
It receives whatever is left after selling costs, accrued interest, property taxes, insurance and the first mortgage are paid in full. In a shortfall that can be a partial recovery or nothing at all.
Is a second mortgage investment always riskier than a first?
Against the same property at the same time, yes — it recovers later and absorbs loss first. A second on a conservative combined ratio against a highly marketable property can still be a better risk than a first on a stretched ratio against an illiquid one, so compare the whole picture rather than the label.
How much more should a second mortgage pay than a first?
There is no fixed premium. What matters is whether the premium you are offered is proportionate to the combined loan-to-value, the marketability of the property and the speed of enforcement where it sits.
Does the province really change the risk on a second mortgage?
Materially. Enforcement speed determines how many months of carrying costs accumulate before a sale completes, and those costs come out of the residual that would repay a second charge. Power-of-sale provinces are generally faster than judicial ones.
Can a second mortgage holder force a sale?
A second charge generally has its own enforcement rights, but exercising them means dealing with the first mortgage, which has to be paid in full out of proceeds. In practice a second often has less room to act than its registered rights suggest.
