The inherited tenant (from the seller&Roofstock) along with the illegal human and animal occupants got evicted, trashed the property, left a whole ecosystem of vermins behind.

Not sure if you're looking only at real estate, but there's also a wider ecosystem of crowdfunding choices, including P2P loans (which arguably isn't crowdfunding per se, but certainly gets lumped in with other online alternative investing), equity crowdfunding (higher risk and much lower liquidity, but potentially greater returns if you're sufficiently diversified over time).
