Thanks for the suggestions so far. To respond to some of the suggestions:
I checked out ratracerebellion, and those seem like low paying work at home jobs, but I appreciate the new link.
I’m younger (graduated 0-3 years ago in Mechanical Engineering), so I do not have the expertise to consult. I’ve considered tutoring, but online tutoring pays poorly and local tutoring is difficult to find clients (though I may pursue this further).
My spending right now is extremely low, so although I know credit card churning exists, I often can’t meet the spend requirements.
For gas, I get 44 mpg average (have been tracking since January 1st), and have a local station that offers a credit card price that is the same as the lowest cash prices in my area, so it’s generally $50 or less for the month (commute is far, but saves me money since I can live at home).
Tradelines I want to do, but am waiting to build up my credit a bit more (I have a high score of 750+, but since I’m younger my credit history isn’t as long and I wouldn’t want any of my current cards to be closed. I’m gradually opening new credit cards so I can do tradelines in a year or two.).
The low balance forgiveness is interesting, but it seems like it is high risk, low reward. If I screw up (for example, the card’s policy changes and I didn’t check the statement because it’s always 0), it can hurt my credit score. And if I do everything right, maybe I’ll get $24 for the year, or even $100 if I have a ton of such cards.
So I like the idea of things like tradelines and churning (those are truly high pay for low hours), but I need to wait to do them and am looking for other high pay low hour ideas. I appreciate those suggested so far, but would love to hear more.
