Most investors obsess over cap rates and cash-on-cash returns. Those matter, but they won't tell you if your portfolio is actually scaling or slowly dying.

After managing 20+ urban units across 3 markets, here are the 3 numbers I check every single week:

1. Revenue Per Available Night (RevPAN)

Not occupancy. Not ADR. RevPAN tells you the real story — it factors in both. An 85% occupied unit at $150/night beats a 95% occupied unit at $120/night every time. Track RevPAN by unit, by market, by month.

2. Guest Acquisition Cost (GAC)

How much are you spending to fill each booking? If you're 100% reliant on Airbnb, your GAC is hidden in their 15% service fee. Direct bookings, repeat guests, and corporate contracts crush your GAC over time.

3. Turnover Cost Per Unit

Cleaning, supplies, maintenance, guest comms. Most operators underestimate this by 40%. When you're at 5 units it's manageable. At 15 units it's a margin killer if you haven't systemized it.

The operators who scale past 10 units are the ones tracking these religiously. Everyone else plateaus.
