I like the potential idea of having diversification in a RE portfolio. But I would never do it because I wouldn't be in control of the investment - if I'm only a 10% owner of a property through this Touzi group then I'm just along for the ride. If I want to sell, too bad, but if they want to sell, I guess we're selling, even if it's not convenient for me tax-wise on the timing.
One thing I don't like about their website is they don't explain how they make money. I'd prefer they explain that upfront, even if it's generalities like "we take an asset management fee on an annual basis" or "we do the property management and fund ourselves that way".
I'm not an RE investor, but I don't see why bigger RE assets are necessarily better investments. It seems to me that they might be more complicated, because bigger more expensive properties might have factors such as employees, tenants, government regulation, etc. Compared to that, a SFH or a duplex or something seems much more straightforward and easier to analyze the financials on, and thus lower risk. But I'll defer to actual RE investors on this.
