Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Gross Revenue = ADR × Occupied Nights + Cleaning Fees | Net Cash Flow = Gross Revenue - OpEx - Mortgage

Step-by-Step Mathematical Derivation

1
Nightly Booking Realization

Booked Nights = 365 × (Occupancy% / 100) = 365 × 0.68 = 248 nights.

2
Top-Line Revenue Realization

Gross Annual Revenue = Booked Nights × ADR. 248 × $245 = $60,809/yr ($5,067/mo).

3
Hospitality Operating Cost Burden

STRs incur higher operating expenses than long-term rentals: utilities, consumable amenities, PMS software, co-host fees, and high-frequency maintenance consume 25% to 35% of gross revenue.

Frequently Asked Questions

What is the STR Tax Loophole? +
Under Treasury Regulation Section 1.469-1T(e)(3)(ii)(A), short-term rentals with an average guest stay of 7 days or less are classified as non-rental businesses. If you materially participate (100+ hours), cost segregation depreciation losses can shelter W-2 and active business income without needing Real Estate Professional Status.
What is a healthy STR occupancy rate? +
National average STR occupancy is 55% to 65%. Well-located, highly reviewed properties with dynamic pricing software (PriceLabs, Wheelhouse) achieve 70% to 80%.
