Three years and 6k in pooled funds. The only near miss was paperwork.
I wanted income without becoming a landlord and I wanted to start small enough that a mistake wouldn't matter. So I put 2k each into three pooled offerings on two platforms, roughly three years ago, and left them alone.
What happened. Distributions came quarterly, mostly on time, once about three weeks late with an email explaining why. Blended across the three, I've received about 1,280 in distributions on 6k over three years, so call it 7.1% a year. One of the three cut its distribution rate partway through, from an annualized 8% to 6%, and told me in advance in a letter I actually read. The other two held steady. Two of the three also report a share value that has moved a little in both directions, so my paper total isn't exactly 6k plus distributions, it's a bit under.
The part that nearly broke it was tax paperwork. One fund sent a 1099 in February. Another sent a K-1 in late March, which meant my return got filed later than I've ever filed anything, and I hadn't budgeted for a preparer who charges more for a K-1. That's a small thing but it was the only genuine surprise in three years, and it would have been worse if I'd owned nine of these instead of three. Everyone's tax situation is different so ask your own preparer what a K-1 does to your filing.
What I'd keep. Small first amounts. A one-page spreadsheet with the date and amount of every distribution, because the platform dashboards each calculate returns differently and I wanted one number I trusted. And reading the letters. The distribution cut was announced and I understood why before it happened, which is most of the reason it didn't bother me.
