That website's Flash popup is quite annoying, no?
If you want to invest invest in shopping centers, a public REIT is a much safer bet. KIM is one of the most respected of all REITs, and FRT and DDR are also very well run.
Nexregen's playing on the fear and inflexibility of the older real estate investors, the ones who were looking at 8-10% cash-on-cash in the 1980s & 1990s but aren't getting the same bargains today. Some of these people are also sitting on huge cap gains taxes and letting that fear wag the tail of their investment dog.
A local well-regarded realtor has been selling the heck out of his partnership with a similar 1031/TIC company to Hawaii landlords. (He knows he won't be able to sell their rental properties any other way.) They're generally older, some in their 70s or even 80s, who have been mostly neglecting their property investments. They'd see 4-6% as a huge gain over their current 2-3% returns. Ironically the realtor was one of the first customers-- he sunk $200K into an apartment building in July 2005. By New Orleans. But the building was insured (although not the rent receipts) and I suspect that the investment is a rounding error on his total portfolio. He's in his 70s and has already affirmed that he's never retiring.
Nexregen probably offers a structure inferring a "safe" cashflow with the prospect of an occasional cap gain. Not much different than the assurances of an annuity salesman, albeit with a lower-quality guarantee to its duration.
I notice that the $2500 minimum will also bring in a lot of [-]suckers[/-] new investors who can't afford down payments, landlord effort, home maintenance expenses, and other barriers to entering the real estate market. They'll certainly get an education, although they may not get rich as quickly as they expect...
