Sell what you already own

Resale, thrift flips, furniture, marketplaces — fees, shipping, and time cost included.

Time: 3–15 hrs/wk Capital: $0–$100 Typical band: $200–$2k/mo

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.
