It's an option to note, I haven't used them as I'm not sure I'd have a good chance of being able to get what I want (since obviously there has to be a seller for me to buy), and the fees also seem pretty notable (5%, and/or up to 2% annual), maybe with some other potential issues of distribution/ownership (it seems it's not equivalent to owning the shares, but owning part of another entity that does own the shares). But, it may be a lot nicer than nothing for some, so thanks for reminding me of it.
The fees are actually a bit higher, 5% from the buyer and 5% from the seller. I haven’t seen a management fee with either of those, though, at least with the single issue purchases - their multi-company funds might be different.
And you do own shares in an SPV instead of owning the shares outright, but that’s a lot of what makes the lower minimums possible.
