After many years of legal struggles an American friend with no money/income will soon receive a large sum (several $100k's) from a guy she decades ago lend a lot of money to finance his first movie (He made career, but somehow "forgot" to pay back the loans, but is now finally forced to do so).

As she has no home but a beautiful piece of land she wanted to build a small house there. I told her afterwards she would be in a similar situation as now: House, but no money to live from, that she should do that only when having a regular income. Now she asks me:

Or figure out how to invest it to be stable'..
What do you suggest???

First idea was "What Jim always suggests ... Equal Weight Index Fund ... RSP ... QQQE ... less overvalued than S&P500".

But I don't know whether that's still true. Since Jim last time(?) recommended QQQE as not overvalued it was $64 (June 2022), but it's 15% higher since, so probably also got a bit ahead of itself. Whether RSP is cheap or expensive I don't know at all.

So I don't really know what to reply.

What would you suggest?
