Kingston Housing: 5.8 Months of Inventory Signals Strong Buyer Leverage Amidst Rising Mortgage Costs

Market summary

Kingston's months of inventory hit 5.8 in August 2026, far exceeding the 3.6-month seasonal norm. Record new listings and rising mortgage rates are shifting leverage to buyers, though price declines remain modest so far.

Central finding

Kingston's housing market has shifted decisively toward buyer conditions, with months of inventory reaching 5.8 in August 2026, well above the 3.6-month long-run seasonal average. This imbalance, driven by record new listings and slowing sales, creates negotiating leverage for buyers and downward pressure on price growth.

How the numbers connect

Kingston's months of inventory in August 2026 stood 61% above its long-run seasonal average, indicating a significant shift toward buyer leverage. Calculation: 5.8 (Aug 2026) - 3.6 (long-run Aug avg) = 2.2 months above seasonal norm; 5.8 / 3.6 = 1.61, or 61% above the balanced benchmark. Definitions: Months of inventory is the number of months it would take to sell current inventories at the current rate of sales activity. The long-run average of 3.6 months applies specifically to the end of August. Limit: This calculation compares a single point-in-time ratio to a historical seasonal average. It does not establish a trend, structural change, or cause for the deviation. Sources: [Kingston and Area Real Estate Association | CREA Statistics]

Inventory Surplus Defines Buyer Leverage

Kingston's months of inventory numbered 5.8 at the end of August 2026, up from 5.6 months at the end of August 2025 and significantly above the long-run average of 3.6 months for this time of year. This metric, which represents the number of months it would take to sell current inventories at the current rate of sales activity, indicates a clear buyer's market. The 61% deviation from the seasonal norm suggests that supply is substantially outpacing demand, creating negotiating advantages for purchasers.

This imbalance is reinforced by record new listings, with 562 units added in August 2026, the highest count for that month in a decade and 13.3% higher than August 2025. While the overall MLS HPI composite benchmark price rose just 0.2% year-over-year to $550,100, the high inventory level implies that this price stability is fragile. Buyers can expect increased choice and potential for price reductions, particularly in segments where inventory is most concentrated.

Rising Rates Constrain Affordability

National financing conditions are tightening, with borrowers renewing pandemic-era five-year fixed-rate mortgages facing an average 15% increase in monthly payments. This affects approximately 12% of all outstanding Canadian mortgages over the next year. In Canada, the lowest available five-year fixed mortgage rate was 4.24% as of September 18, 2026, while the Bank of Canada held its policy rate steady at 2.25%. These broader national figures do not measure Kingston-specific outcomes but indicate a general environment of reduced borrowing capacity.

Long-term bond yields have risen globally, including in Canada, causing borrowers to face higher fixed mortgage rates similar to conditions seen in March and April 2026. The five-year Government of Canada bond yield has risen to around 3.65%, exerting upward pressure on fixed rates. For Kingston, this means that while local inventory is high, the pool of qualified buyers may shrink as renewal costs rise, potentially extending the duration of the buyer's market and increasing pressure on sellers to adjust prices.

Segmented Supply Shows Mixed Signals

While the overall market shows a buyer's tilt, specific segments present different dynamics. Months of inventory for single detached homes numbered 4.2 at the end of the second quarter of 2026, unchanged from the 4.2 months recorded at the end of the second quarter of 2025. This stability suggests that the single-family segment is more balanced than the aggregate figure implies, with median sale prices for these homes rising 0.4% year-over-year to $632,700.

In contrast, the townhouse/row unit benchmark price was $408,100 in August 2026, increasing by 1.4% compared to a year earlier. This divergence indicates that the buyer's market is not uniform across all property types. Buyers seeking single-family homes may face less negotiating leverage than those looking at townhouses or apartments, where inventory levels are likely higher. Understanding these segment-specific differences is crucial for making informed decisions in the current market.

The strongest counter-case

The MLS HPI composite benchmark price rose 0.2% year-over-year in August 2026, suggesting that despite high inventory, prices have not yet declined. Additionally, single-family home inventory remained stable at 4.2 months in Q2 2026, indicating that the buyer's market may be concentrated in other property types rather than being uniform across all segments.

The early signal

New residential listings reached 562 units in August 2026, the highest count for that month in ten years, up 13.3% from August 2025. How it reaches the market: A surge in new residential listings increases the numerator of the months-of-inventory ratio. If sales volume does not rise proportionally, the ratio expands, signaling a shift from seller to buyer leverage and potential price softening. Typical lead time: New listings typically lead changes in months of inventory by one to two months as they accumulate in active stock before affecting absorption ratios.

Next 3 months, through December 2026

Prices: flat. Flat to slightly falling prices for all property types in Kingston, as high inventory continues to outpace sales activity. Why: August 2026 months of inventory at 5.8 months exceeds the 3.6-month seasonal average. Rising fixed mortgage rates and pandemic-era renewals are expected to dampen demand further in the short term, keeping supply ahead of absorption. Buyers: buy now. Buyers benefit from maximum negotiating leverage and a wide selection of properties, allowing for price reductions and favorable terms. Sellers: wait. Sellers face prolonged days on market and reduced offer competition; waiting may allow for better timing if inventory normalizes, but risks further price erosion. Watch: A drop in months of inventory below 4.5 months or a year-over-year increase in sales volume exceeding 10% would signal a return to balance. Confidence: moderate.

Next 6 months, through March 2027

Prices: flat. Flat prices for all property types in Kingston, with potential for minor declines in higher-priced segments as affordability constraints bite harder. Why: The combination of record new listings and constrained financing capacity suggests continued buyer leverage. However, the 0.2% year-over-year price stability in August 2026 indicates that sellers are resisting deep cuts, leading to a stalemate where prices hold firm despite high inventory. Buyers: either way. Buyers can still negotiate effectively, but the risk of missing a desired property increases if inventory begins to normalize. Acting now secures choice; waiting may yield similar pricing with less selection. Sellers: wait. Sellers should wait for potential seasonal demand spikes in spring, though this carries the risk of entering a market with even higher inventory if new listings continue to surge. Watch: A sustained decline in new listings below the five-year average or a significant drop in interest rates would shift the market back toward seller conditions. Confidence: low.

Next 12 months, through September 2027

Prices: falling. Falling prices for all property types in Kingston, with a projected range of 2-5% decline as the full impact of high inventory and financing costs materializes. Why: Over 12 months, the cumulative effect of high inventory and financing costs may force price adjustments. The national context of a 3.6% Ontario price decline suggests Kingston may eventually follow suit, though local resilience could delay this. The 5.8-month inventory level provides ample cushion for price negotiation. Buyers: buy now. Buyers who act within this window are likely to secure the best pricing opportunities before any potential market correction stabilizes or reverses. Waiting risks facing a tighter market if inventory clears faster than expected. Sellers: list now. Sellers who need to transact should do so now to avoid deeper price concessions later. Those who can wait may see improved conditions if inventory normalizes, but the risk of further price erosion is significant. Watch: A reversal in the trend of new listings, a significant reduction in interest rates, or a local economic boom that boosts demand would overturn the falling price expectation. Confidence: low.

Assumptions: Mortgage renewal pressures continue to constrain buyer purchasing power over the next 12 months; New listing volumes remain elevated near decade-high levels through the outlook period; No major local policy changes alter development charges or zoning requirements within the horizon. What would reverse this: If months of inventory fall below 4.5 months due to a sharp drop in new listings or a surge in sales velocity, the buyer's market designation would reverse, restoring seller leverage and potentially halting price stagnation.
