James Cooper Mansion — Rental Market Data

James Cooper Mansion has one active listing as of August 31, 2026, asking $2,500 per month with both the average and median rent at $2,500. The available suite spans 645 square feet at an asking rate of $3.88 per square foot, and the 100 percent layout share is a one-bedroom-plus-den configuration. With only a single unit on the market, inventory leans toward a compact entry-level-plus-den profile rather than multi-bedroom executive layouts, which dominated the building's historical lease activity at 80 percent of closed transactions.

The sole active layout at James Cooper Mansion is a one-bedroom-plus-den, representing 100 percent of available inventory with a single listing. That unit asks $2,500 per month over 645 square feet at $3.88 per square foot, and no other bedroom tiers are currently on the market. Renters seeking two-bedroom or larger configurations must look to the 105 other active listings across the Cabbagetown submarket.

James Cooper Mansion shows a minimum and maximum asking rent of $2,500 per month, producing a dollar spread of zero and a percentage spread of zero percent given the single active unit. The entry-level and peak suite are the same one-bedroom-plus-den at 645 square feet and $3.88 per square foot, so there is no internal price gradient to evaluate. With only one listing, the pricing spread cannot be meaningfully differentiated, and renters should benchmark against the Cabbagetown submarket range for context.

James Cooper Mansion's active den premium and square-footage delta cannot be quantified due to insufficient paired sample data, so no marginal cost per square foot for the den component can be isolated. Active parking premiums also cannot be reliably isolated from the current listing data, as the sample is flagged as an anomalous outlier or insufficient for a confident quote. Historical lease records do confirm a verified parking premium of $167 per month, which serves as the most reliable reference point for budgeting a parking stall at this address.

James Cooper Mansion's active asking rent of $2,500 per month and rate of $3.88 per square foot both sit below the Cabbagetown submarket benchmarks of $3,178 per month and $4.33 per square foot respectively. The 10.4 percent discount on a per-square-foot basis is driven by the active suite's 645-square-foot footprint being 89 square feet smaller than the submarket implied average of 734 square feet, meaning the lower nominal rent reflects compact sizing rather than a pricing concession. The building holds one out of 106 active listings in the submarket, representing roughly 0.9 percent of total available inventory.

James Cooper Mansion's all-time average realized lease rent of $2,973 per month sits $956 below the four-comp cluster average of $3,929, a gap driven largely by The Rosedale's outlier luxury pricing. Against the two highest-volume active peers, the subject commands a higher monthly rent: Burke Condos at 605-609 Sherbourne Street (0.09 km, 157 closed leases) averaged $2,542 per month at $3.66 per square foot across 703 square feet, meaning the subject's rent runs $431 higher; The Rosedale on Bloor at 395 Bloor St E (0.16 km, 54 closed leases) averaged $2,554 per month at $4.07 per square foot across 632 square feet, placing the subject $419 above. The two low-volume references carry very different signals: The Selby at 25 Selby Street (0.04 km, one closed lease) posted $2,419 per month at $4.01 per square foot over 603 square feet, with the subject $554 higher; The Rosedale at 409 Bloor St E (0.15 km, one closed lease) recorded $8,200 per month at $11.71 per square foot across 700 square feet, a luxury-tier data point that pulls the comp average well above the subject's realized rate.

James Cooper Mansion leases at $3.70 per square foot across an average 811-square-foot suite, a rate that undercuts the submarket leased benchmark of $4.23 per square foot by roughly 13 percent while delivering substantially more interior space than every nearby competitor. Against Burke Condos (0.09 km, 157 closed leases), the subject commands a $0.04 per square foot (1.1 percent) premium and provides 108 more square feet, so the $431-per-month rent gap reflects both a modest rate premium and a larger footprint. The Rosedale on Bloor (0.16 km, 54 closed leases) presents the inverse trade-off: the subject trades at a $0.37 per square foot (9.1 percent) discount yet still posts a $419 higher nominal rent because its suites run 179 square feet larger. The Selby (0.04 km, one closed lease) shows the same pattern at a wider spread—$0.31 per square foot (7.7 percent) discount, 208 more square feet, and a $554 higher monthly rent—while The Rosedale (0.15 km, one closed lease) operates in an entirely different price tier at $11.71 per square foot, making direct rate comparison less meaningful for mainstream renters.

James Cooper Mansion offers a nine-item lifestyle package—concierge and security, gym and fitness centre, games and billiards room, media and theatre room, party and lounge room, meeting room, sauna and steam room, yoga studio, and garden and courtyard—that positions it as a solid mid-range amenity building without the aquatic or rooftop features that define its newer competitors. The Selby (2019) and Burke Condos (2025) both add outdoor pools, rooftop terraces, EV charging, pet wash stations, and dedicated business centres that the subject does not carry, while The Rosedale on Bloor (2023) differentiates with an indoor pool and a dining room and kitchen. The subject's sauna and steam room, meeting room, and games and billiards room are absent from Burke Condos and The Rosedale on Bloor, giving it a small edge in wellness and informal work flexibility. This package best serves cost-conscious young professionals and small households in Cabbagetown who want a full-service residential experience with fitness, social, and remote-work spaces but do not require resort-style aquatic or rooftop amenities.
