My read

The real story here is the finished basement suite with a separate entrance, because that changes the carrying cost conversation entirely for the right buyer. At 1,949 sqft above grade plus a full developed lower level, you're getting over 2,500 sqft of usable space, and the suite gives you income flexibility or multi-generational living that most comparables in the 600s don't offer. That's the lens I'd put on this one before anything else.

What I'd pay

$655,000

Recent active comps in New Brighton show comparable four-bedrooms without a suite transacting in the $565,000 to $630,000 range at similar square footage, and with the SE market sitting at 3.05% below last year's levels, a buyer doing their homework might use those sold anchors (not just asking prices) to frame their offer, keeping in mind that the suite and separate entrance do justify a premium over a standard four-bedroom in the same price band. This is how I'd think about value here, not a suggestion the asking price is wrong.

The play

If you're a buyer who wants to offset your mortgage with suite income, or you're bringing extended family, this is one of the more functional setups you'll find under $700,000 in SE Calgary right now. Before you make a move, I'd get clarity on the suite's permit history and have a home inspector walk the 2008-era mechanical systems, because forced-air furnaces and hot water tanks in this build era are worth knowing the age of. Come in informed and you'll negotiate with confidence.

Risks

Worth confirming in person whether the basement suite development was permitted and whether it meets current city requirements, since it's listed as an illegal suite.
No central air conditioning is listed, which is worth factoring into your summer comfort budget for a 2008 build in Calgary.
The side-access door through the garage is the suite's separate entrance, so it's worth walking through how that arrangement works for privacy between the main home and suite occupants.
Annual taxes of $4,651 are reasonable for the size, but worth verifying the current assessment given the 2025-2026 Calgary reassessment cycle.
