@Frank S., I think I see the disconnect.
Your audience is people who cannot afford to spend more than a few minutes a month on their investing portfolio. Or are seriously disinterested. For all those who belong to this category, I agree completely with your advice. Diversify and use index funds, or hold liquid funds if your need is short-term.
Going by your advice, all BP investors should invest in real estate only via REIT's or real estate index funds. At most you might own your own house. Because... God forbid, how can you ever predict that a particular property will be a good investment!
I, on the other hand, am a full-time investor. I was a full-time investor when I was trading stocks. I thought BP is for investors or people who aspire to be investors. If you want to be a serious investor, and not just someone who pretends to be one, you need to invest serious time in studying markets and assets. And... try to predict how they will behave. If you cannot do this, get out of the market as an "investor". In other words, stop picking assets. I did exactly that in 2009 with stocks!
Btw, I am not a guru and do not have any education to sell. Nor am I a property developer raising cash. RehabDaddy is a crowdfunding portal regulated by securities law. Which means I cannot even invest personally in the investment offerings on my portal. So if I am selling anything, I am selling a service that allows you to raise cash or invest. My target market is full-time active real estate developers and rehabbers raising capital. And serious "investors" who want to fund them, one investment at a time.
I can tell that you, Mr Sanchez are neither a property developer, nor a rehabber, nor a serious "investor". Good luck with your diversified index funds.
