Three platforms, one bet, which I only saw afterward
Service business pays the bills, so the investing side is meant to be hands off. Over about two years I put $88k into eight equity positions across three platforms, deliberately spreading across platforms because I'd read that platform risk was the thing to manage.
Here's what I actually built, which I only saw properly when I put all eight into one spreadsheet last winter. Six of eight were multifamily. Seven of eight were bridge or short-term floating rate debt at the property level with a rate cap purchased for the initial term. Five of eight were in sunbelt metros with heavy new supply. Every one of them assumed an exit cap at or below the entry cap and a refinance inside three years.
So I owned one trade eight times. When rates moved, the caps on four of them ran out of term and the sponsors had to buy new protection at a price nobody had budgeted. Distributions stopped on five positions inside the same two quarters. Two have gone to capital calls, which I declined on both, one of them diluting me by a bit over a third. One sold at a price that returned roughly 60 cents of my equity. The rest are extending and hoping.
Marked honestly I'm down about 28 percent on the eight positions combined, with three of them still live and unresolved. The three-platform spread did absolutely nothing for me because the platforms weren't the risk. They were all selling the same product to the same audience in the same vintage.
What I'd do differently: diversify by what would have to go wrong, not by logo. Before funding, write down the one assumption the deal dies without. If two deals share that sentence, they are one position and should be sized as one.
