What costs break Canmore STR cash flow most often?

Financing, strata fees and insurance resets, and management or turnover costs — fixed lines that do not shrink when nights go empty.

Why are special assessments critical?

They are lumpy cash calls that can erase multiple months of gross revenue in one levy — models without reserve risk are not authoritative.

How does the public calculator simplify costs?

It uses financing on borrowed dollars plus a flat monthly operating reserve so you can stress-test quickly — not a substitute for strata documents.

How do Self-Sustaining, Break-even, and Negative Carry relate to costs?

Self-Sustaining means the property generates positive monthly cash flow after the modeled bundle. Break-even means it roughly covers costs. Negative Carry means it loses money monthly — financing and strata lines are usually the lever.

Canmore STR cost breakdown

Every line item that competes with gross bookings — aligned with property analyses.

Direct answer: Canmore STR net cash flow loses to financing, strata, insurance, turnover, and lumpy special assessments more often than to “low ADR.” Self-Sustaining = positive monthly cash flow; Break-even = roughly covers costs; Negative Carry = loses money monthly.

Revenue stress bands on this site often pair roughly 55%–75% occupancy with nightly rates near $250–$450 before discounting — costs still decide the payback label.

What financing costs hit monthly cash flow?

Principal and interest are cash out the door. In Canmore’s price bands, small rate moves change absolute dollars fast. The site calculator approximates financing on the borrowed balance so you can compare deals consistently.

How large are condo / strata fees in practice?

Strata fees are often materially higher than in non-resort Canadian cities; they are fixed whether you book zero or thirty nights. Insurance line items inside strata budgets have moved sharply in many Alberta resort buildings — treat MLS fee fields as a floor, not a ceiling.

Building-specific reserve and envelope risk sits in condo risk guide.

What do cleaning and turnover cost?

Per-stay cleaning commonly lands roughly $80–$180+ depending on unit size and operator; high rotation months stack costs even when ADR looks strong.

What are platform and channel fees?

OTA and direct-booking stacks often take single-digit to low-teens percentages off gross — enough to erase thousands per month on busy properties. Net revenue, not screenshot gross, feeds viability.

What maintenance and CapEx should you reserve?

Appliances, wear items, and minor repairs are recurring; older buildings add envelope and mechanical exposure. If your model has zero maintenance reserve, it is not conservative.

Why are special assessments the hidden killer?

Special assessments are binary cash events — parking membrane, envelope, elevator, insurance deductibles — that can demand five- or six-figure capital from owners. They are the main reason “the numbers worked last year” fails this year. Read depreciation reports and meeting minutes before acquisition.

Cost categories (checklist)
Category	Notes
Mortgage	Rate + amortization; scales with LTV
Strata + insurance	Fixed monthly; can jump after renewals
Management	Often % of gross if outsourced
Platforms + cleaning	Variable with bookings
Special assessments	Lumpy; can dwarf a season of profit

Tie revenue to this stack using rental income reality and modeled examples such as $1M analysis.

Key takeaways

Fixed strata and financing dominate — they do not flex when occupancy dips.
Special assessments are lumpy killers; read reserves before you trust net.
