Which do you prefer for quick income, wholesale, of fix n flip?

[Brandon Rizzo]

I'm looking at the options to grow my capital, so I'm curious what the veterans think of these options. If you needed to make some quick cash, especially working with a hard money lender or another investor, which option would you prefer and why? 

I've heard some investors say that wholesaling is the be all end all of starting out in real estate with no startup capital, while I've heard others shame it as being underhanded. 

Would you consider it underhanded to go out and find motivated sellers, negotiate a deal, and sell that deal to an investor with the capital (at a good discount, obviously, I wouldn't offer another investor something that they couldn't make at least $20,000+ on) or would you consider it a prudent way to get familiar with the markets and networks, with minimal asset liability?

If you've got any experience with wholesaling, I want to hear your opinion please, and your favorite story if you have one to share!
