I checked the sponsor's wins and never asked about the deals that didn't work
Three years ago I put $50,000 into a self-storage syndication. First LP check I ever wrote. The sponsor's deck had five prior deals on it, all full cycle, all between 1.7x and 2.2x equity. I read the whole PPM twice, asked about the debt, asked about the market, felt good.
What I never asked: is this every deal you've done, or is this the five you like showing?
It was the second one. I found out at an LP update call in year two when another investor asked about a deal that wasn't on the deck. There were three others. Two of them were fine and boring, one of them was a total loss where the LPs got nothing back after a lender took the property. The sponsor answered honestly enough when asked directly. He just never volunteered it, and I never made him.
My deal isn't a disaster. Distributions started at 6% annualized, dropped to 2% in month 19 when the lease-up stalled, and have been paused for eleven months. The last valuation letter put the property below what we paid. Hold was pitched at three to five years and I now assume seven.
What I'd do differently, plainly: ask for a written list of every deal the sponsor has ever sponsored or co-sponsored, including the ones that lost money, and ask to speak to two LPs from the worst one. If the list is curated, that tells me something before I wire anything.
