I've always had a knack for interior decorating/design, and a TON of stuff in my home is from thrift stores/Craigslist/secondhand market. I also sold a bunch of my own belongings earlier this year to help me pay off CC debt, but until recently it never dawned on me to try to put those skills to work for profit.
So far in July, I've made $250 buy buying cheap (less than $30) outdated furniture off Craigslist, flipping, and reselling. I have 3 other projects in the works that should wrap up by end of July. If those sales go according to plan, I think I will close the month at +$365 (net)! Not too shabby for about 20 hours work, which I actually quite enjoy.
For anyone interested in giving it a shot, tall dressers have been my easiest selling item. Pretty much guaranteed ROI.
