Reselling from yard sales is straightforward in theory: buy underpriced items at garage sales, sell them at a profit on eBay, Facebook Marketplace, Poshmark, or Mercari. The hard part is knowing what to buy, what it's actually worth, and where to sell it.
Use the eBay app to check "sold listings" for any item you're considering. Sold listings show what people actually paid — not just asking prices that may sit unsold forever. If a $4 item at a yard sale is consistently selling for $45 on eBay, you've found something worth picking up.
eBay takes roughly 13 to 15 percent in fees. Poshmark takes 20 percent on items under $15. Shipping costs money and takes time. Factor all of that in before you buy. An item that sells for $20 might net you $10 to $12 after fees and shipping — is that worth the effort at this scale?
The most successful resellers specialize. They know one category inside and out — vintage clothing, vintage cameras, tools, ceramics — and they can evaluate items in that category instantly without research. Start with something you already know and build expertise from there.
Don't invest heavily before you understand your market. Spend $50 to $100 on test purchases, sell them, understand the process, then scale up once you've found what works.
