Passive-ish income
Rentals of stuff, dividends, and productized assets — what is truly passive vs ongoing work.
Time: Setup heavy
Capital: Varies
Typical band: Wide range
How DollarFlourish scores this category
- We show net ranges when we can: fees, gas, ads, and tax set-asides matter more than app screenshots.
- Time is a cost. A $30/hr gig that needs 90 minutes of unpaid waiting is not a $30/hr gig.
- If a hustle only works with unpaid inventory, unpaid learning, or unpaid customer service, we say so.
