Kepler: Kingston's decade-high inventory and flat HPI signal a buyer's shift

Key facts and reporting periods

Market summary

Kingston's August 2026 months of inventory reached 5.8, well above the 3.6-month seasonal average, while the MLS HPI composite benchmark price rose just 0.2% year-over-year to $550,100. These city-level measures indicate a balanced-to-buyer market in Kingston, though they are not measured at the Kepler neighbourhood level.

Central finding

The strongest measured finding is that Kingston's residential market shifted toward buyers in August 2026, with months of inventory at 5.8 (up from 5.6 in August 2025) and new listings at a decade-high 562 units (+13.3% YoY), while the HPI composite benchmark price remained essentially flat at +0.2% YoY. This matters because it suggests sellers face more competition and buyers have greater negotiating leverage in Kingston, though no target-scoped data confirms this for Kepler specifically.

How the numbers connect

Calculates the percentage deviation of Kingston's August 2026 months of inventory from its long-run seasonal average. Calculation: (5.8 - 3.6) / 3.6 * 100 = 61.1% Definitions: Months of inventory is the ratio of active listings to monthly sales activity. The 3.6-month figure is the long-run average for August in the Kingston and Area board. Limit: This calculation establishes only the magnitude of deviation from the seasonal norm; it does not establish a trend, cause, or future trajectory.

Kingston's Inventory Surge Outpaces Price Growth

In August 2026, the Kingston and Area Real Estate Association reported months of inventory at 5.8, up from 5.6 in August 2025 and significantly above the long-run seasonal average of 3.6 months. New residential listings reached 562 units, a 13.3% increase from August 2025 and the highest count for an August in a decade. Active listings stood at 1,397 units, a level not seen since early 2017. These figures are measured at the city level and do not establish a specific outcome for the Kepler neighbourhood.

Despite this supply expansion, the overall MLS HPI composite benchmark price was $550,100 in August 2026, up just 0.2% compared to August 2025. The average sale price increased by 2.7% to $612,691, but the HPI, which tracks like-for-like changes, indicates near-flat price appreciation. This divergence between rising inventory and stable prices suggests a market in transition, where seller enthusiasm has outpaced buyer absorption, creating a buyer's market condition as characterized by Wahi for all property types in Kingston.

Mortgage Renewals and Rate Pressure Shape Demand

National financing conditions present a headwind for demand. Over the next year, the last of the five-year fixed-rate mortgages taken out during the pandemic will come up for renewal, representing approximately 12% of all outstanding Canadian mortgages. On average, these borrowers can expect their monthly payments to increase by 15%. As of September 18, 2026, the lowest available five-year fixed mortgage rate in Canada is 4.24%, while the Bank of Canada held its policy rate steady at 2.25% on September 2, 2026. Rising five-year Government of Canada bond yields near 3.65% are exerting upward pressure on fixed rates.

These financing pressures are national in scope and do not directly measure their impact on Kepler-specific transactions. However, the mechanism is clear: higher renewal costs reduce household disposable income and borrowing capacity, potentially dampening demand. The fact that national mortgage delinquency rates remain low at 0.24% suggests most borrowers are absorbing these increases, but the cumulative effect on marginal buyers in a high-inventory market like Kingston could be significant.

Federal Infrastructure Funds Target Housing Supply

The Canada Housing Infrastructure Fund (CHIF) allocates $6 billion over 10 years to accelerate the construction and upgrading of housing-enabling water, wastewater, stormwater, and solid waste infrastructure. Communities with populations over 30,000 must implement zoning changes allowing four units as-of-right to qualify for CHIF funding. The Direct Delivery stream provides up to $1 billion over eight years directly to eligible recipients, such as municipalities, to address pressing infrastructure needs. Projects under this stream must be substantially completed by September 2031.

These federal initiatives aim to remove infrastructure bottlenecks that constrain housing supply, indirectly supporting development and potentially affordability through increased density. In Ontario, student housing deliveries are set to reach a record in 2026, with the Greater Toronto Area leading with 2,734 projected completions, representing 43% of the provincial total.

Kingston Exceeds Provincial Housing Targets

The City of Kingston reported that its Planning Services exceeded the Provincial Housing Target by issuing 800 building permits in 2023. Despite this increase in new construction approvals, the rental vacancy rate for the Kingston Census Metropolitan Area declined to 0.8 per cent in 2023. This indicates strong demand for rental housing relative to supply, even as ownership market inventory rises. The city has also launched a new Community Improvement Plan offering property tax incentives to stimulate the construction of rental housing within its urban boundaries, with applications open from June 13, 2024, through December 31, 2026.

These municipal actions reflect a strategic effort to balance ownership and rental supply, addressing different segments of the housing market. The focus on rental incentives suggests recognition of tight rental conditions, which may influence broader housing dynamics in Kingston.

The strongest counter-case

The strongest counterforce is that the 0.2% HPI increase indicates price stability rather than decline, suggesting that despite higher inventory, demand may be sufficient to support current prices. Additionally, the national mortgage renewal wave (15% payment increase for ~12% of mortgages) could dampen demand further, but delinquency rates remain low (0.24%), indicating borrowers are absorbing higher payments without widespread distress.

The early signal

New residential listings in Kingston reached 562 units in August 2026, a 13.3% increase from August 2025 and the highest count for an August in a decade. How it reaches the market: A surge in new listings increases active inventory, which typically exerts downward pressure on prices and improves buyer leverage by providing more choices and reducing competition among buyers. This measure moves before headline price indices adjust to the new supply-demand balance. Typical lead time: New listings typically lead price adjustments by one to two months, as it takes time for the market to absorb additional inventory and for sellers to adjust pricing strategies.

Next 3 months, through December 2026

Prices: flat. 0% to +1% for Kingston composite benchmark price; not a measured Kepler result. Why: August 2026 HPI was +0.2% YoY with 5.8 months of inventory. High inventory supports flat prices, but stable HPI suggests no immediate decline. Mortgage renewal pressures may moderate demand growth. Buyers: buy now. Buyers benefit from high inventory and flat prices, gaining negotiating leverage without facing rising costs in the short term. Sellers: wait. Sellers face high competition from 1,397 active listings; waiting may allow for better timing if inventory normalizes, but risks further price softening. Watch: A drop in months of inventory below 4.5 or a YoY HPI decline exceeding 1% would overturn the flat price call. Confidence: moderate.

Next 6 months, through March 2027

Prices: falling. -1% to -2% for Kingston composite benchmark price; not a measured Kepler result. Why: If the 15% mortgage payment increase for renewals fully materializes and demand weakens, the high inventory (5.8 months) could drive modest price declines. National sales were 22.6% below the 10-year August average, suggesting persistent demand weakness. Buyers: buy now. Buyers should act now to secure properties before potential price declines, leveraging high inventory and expected softer seller positions. Sellers: wait. Sellers should wait for potential inventory normalization or rate cuts, but risk selling into a declining market if demand continues to weaken. Watch: A sustained increase in monthly sales volume above the 10-year average or a rise in months of inventory above 6.5 would overturn the falling price call. Confidence: low.

Next 12 months, through September 2027

Prices: flat. 0% to +1% for Kingston composite benchmark price; not a measured Kepler result. Why: Long-term factors like federal infrastructure funding (CHIF) and municipal rental incentives may stabilize supply and demand. Population growth in Kingston (+0.65% YoY) provides underlying demand support, offsetting short-term financing pressures. Buyers: either way. Buyers can choose based on individual circumstances; flat prices mean neither urgency nor delay is strongly favored by market direction alone. Sellers: either way. Sellers can list when ready; flat prices mean no significant advantage to timing, but high inventory may require competitive pricing. Watch: A major shift in interest rates (cut or hike >0.5%) or a change in population growth trends would overturn the flat price call. Confidence: low.

Assumptions: Mortgage renewal payment increases of 15% will be absorbed by most borrowers without significant default spikes; Federal and municipal housing policies will continue to be implemented as planned; No major economic shocks or policy changes beyond those currently anticipated. What would reverse this: A rapid decline in interest rates or a surge in immigration-driven demand could reverse the buyer's market, driving prices up despite high inventory. Conversely, a recession or job loss spike could amplify price declines beyond the forecast range.
