After Willow Tufano earned $6,000 from antiquing and selling items on Craigslist, the 14-year-old asked her mom if she could invest in half of a short sale in her home state of Florida.

Tufano earned the money from finding free items or deals online or at antique auctions and leftover furniture from foreclosed homes. She re-sells the items or gives them away on the “free” list on Craigslist.
