The client
A household bought a $398,000 rural property near Cornwall at 10% down, accessed by a private road maintained under a registered road maintenance agreement among the properties that use it.
Purchase price

10% down, insured
Access
Private road under a registered maintenance agreement
$900/year recurring assessment
Combined income
$7,800/month
Other debt

The problem
A private road maintenance agreement's recurring assessment is a real, contractual carrying cost that runs with the property -- but because it is owed to a road association, not a lender or credit grantor, it never shows up on a credit bureau report.
What a bureau-only review will never surface
- ▸The property is accessed by a private road governed by a registered maintenance agreement among its users
- ▸That agreement's own $900/year assessment is a real, recurring obligation, not an optional membership fee
- ▸Because it never reports to a credit bureau, the first lender's initial debt-service calculation never counted it at all
Nothing was hidden. The assessment simply lives in a place a standard bureau-based debt review never looks.
The numbers
Adding the road agreement's own assessment into the file's carrying costs was the entire correction -- everything else about the file was already right.
| The insured purchase, correctly costed | Amount |
|---|---|
| Base mortgage (90% of purchase price) | $358,200 |
| CMHC premium (3.10% at 90% LTV) | +$11,104 |
| Total insured mortgage | $369,304 |
| Total debt service | Without the road assessment | With the road assessment |
|---|---|---|
| Payment at the qualifying rate (6.90%), 25 years | $2,564/mo | $2,564/mo |
| Property tax + heat | $400 | $400 |
| Private road maintenance agreement | -- | $75/mo |
| Car loan | $220 | $220 |
| Total debt service | 40.8% | 41.8% |
40.8% moving to 41.8% is still comfortably inside CMHC's 44% TDS ceiling -- the correction mattered for accuracy, not approval. On a thinner file, a missed carrying cost this size is exactly the kind of gap household debt service ratio data shows lenders now watch closely for.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the property's access as its own line of due diligence, separate from the standard bureau-based debt review.
First, pulled the registered road maintenance agreement itself from the title and property disclosure documents, rather than relying on the bureau-based debt review to surface every carrying cost.
Second, confirmed the current assessment amount directly with the road association, since a private agreement's own fee can change over time and the only reliable figure is the current one.
Third, rebuilt the file's carrying-cost figure to include the assessment before returning it to underwriting, so the TDS figure the lender actually relied on reflected the property's real, complete cost.
The outcome
The purchase funded insured at 38.0% GDS and 41.8% TDS, with Ontario's land transfer tax on the $398,000 purchase coming to $4,445 -- the road agreement itself has no effect on the transfer tax, only on the ongoing carrying cost.
Both figures sit comfortably inside CMHC's 39% GDS and 44% TDS maximums; the file was never close to either ceiling, correctly costed or not.
What to take from this file
- 01A private road maintenance agreement's assessment is a real carrying cost that a credit bureau will never show. It has to be found in title and property disclosure documents, not a debt review.
- 02Confirm the current assessment directly with the road association. A private agreement's own fee can change, and the only reliable figure is the current one, not an old estimate.
- 03Rural and private-road-access properties deserve their own specific due-diligence checklist. The standard bureau-based process was never built to catch this kind of cost.
- 04A missed carrying cost this size can matter on a thinner file even when it doesn't here. This file had room; not every file will.
