I normally invest in real estate and get around 20% of ROI (without much time spending) ... but wanted to explore other avenues with similar GUARANTEED return ??
Snake oil, its the future; and I can get you 100Ks worth easy.<p>Seriously though, this is a dumb question. There is no such thing as guaranteed returns, and anything with a 20% return probably has inherent risks that you don't appreciate, or is completely illiquid. If you want to invest money responsibly and you don't know how, then speak to a financial advisor -- that's what they're there for.
What stage of life are you in? What portion of you savings is this?<p>I Ask because if you are young and have opportunity to earn / save more, I would say yourself. If you are older and this represents a significant portion of your nest egg I would have other suggestions.
