Hard part in a syndication is vetting the operator and making sense of their projected financials without any knowledge of the major assumptions. Many of the vocal/easy to find operators were not doing syndications 15 years ago. The last 15 years has been pretty easy to make money in real estate as prices have continuously grown and cap rates have continued to compress. Interest rates are also crazy cheap. What has this done? Given syndicators and syndication investors increased confidence in how "easy" it is to make money under this business model. As they say in the investment world - past performance does not predict a future results
How will things look when the market interest rate jumps 75 basis points and expenses continue to rise with inflation? Hopefully these are accounted for or tested in the financials prior to the offer but it is rare for projected financials to show profitability decreasing over time as it is not what the investor wants to see.
I think these can be great investments but we all have to acknowledge that there is some risk. The projected return is higher than the OPs bond investment but the risk has more than doubled. When we invest we have to consider our risk tolerance and make an informed decision with the information available.
