Most people getting into house hacking track vanity metrics — total units, total "deals closed," social followers. None of that tells you if the business is healthy.

After building and refining a KPI dashboard across dozens of house hacking operators, here are the 5 numbers that actually matter, weekly:

1. Net Cash Flow Per Unit — not portfolio-wide cash flow. Per-unit. This is the number that tells you if you're actually scaling profit or just scaling headaches.

2. Occupancy Rate (Trailing 4 Weeks) — a single vacancy can wreck a month. Tracking this weekly (not monthly) lets you catch a bad trend before it compounds.

3. Time-to-Fill (Days Vacant) — how many days between move-out and move-in. This is your biggest controllable lever on cash flow and it's almost never tracked.

4. Client/Tenant Onboarding Completion Rate — if you're managing this for others (or scaling to multiple properties), a broken onboarding process is the #1 cause of early churn and bad reviews. Track what % of new tenants/clients complete every step of your onboarding sequence in week one.

5. Referral/Repeat Rate — the real sign your operation is trusted: are past clients or tenants sending you new business without being asked?

The mistake: tracking these monthly or "whenever I remember." Weekly cadence is what turns this from a hobby into a business — you catch problems in days, not months.

If you want the plug-and-play version of this (spreadsheet + the onboarding SOP that keeps #4 above 90%), it's inside House Hacking Blueprint. Happy to answer questions on any of these in the comments.
