How the math works

Savings = (incidents × cost) − annual subscription. Payback = device cost / savings.

2 × $1,500 = $3,000 − $240 sub = $2,760/yr. $300 / $2,760 = 1.3 months.

Frequently Asked Questions

Which device + savings?

NoiseAware: $99–149/device + $9–35/mo cloud. Minut: $179 + $9–25/mo. Roomonitor: $119 + $7–25/mo. Coverage: 1 device per 1,500 sq ft typical, 2–3 for 4-bedroom. Value: detects 80–95% of party events early enough to intervene. Savings: 1 prevented party = $500–5,000 in damages, lost bookings, neighbor complaints. Many city ordinances now require noise monitoring for permitted STR (Scottsdale, Park City, Sedona, Lake Tahoe).

How does this fit STR underwriting?

Short-term rental investors stack this calculator with AirDNA market data, channel mix analysis, seasonal pricing, and HOA/regulatory review. Net contribution after PM, cleaning, supplies, utilities, taxes, insurance and platform fees should be the underwriting target — gross revenue alone is misleading. Always validate with at least 12 months of comp performance.

Airbnb vs VRBO vs Booking economics?

Airbnb: 3% host fee + 14% guest fee, strong urban demand, cancellation policies host-controlled. VRBO: 8% per booking, family/group oriented, longer stays. Booking.com: 15% commission, instant book required, more international. Direct booking: 0% but requires marketing investment. Most STRs use 2–3 channels for 15–30% lift.

Regulatory risk?

STR regulation is fragmenting fast: outright bans (NYC, Honolulu certain zones), licensing caps (SF, Boston, Santa Monica), occupancy taxes (most cities now), HOA bans (private). Always verify zoning, licensing, and HOA rules before underwriting. Insurance and liability waiver also critical. Owner-occupied vs investor STR rules differ materially in many jurisdictions.
