Money is definitely relative. Some people can lose $10K (or much more) in a day in the stock market. For others, it might represent six months of living expenses.
For me, the investment aspect of this would be secondary, as there are similar opportunities with much less risk and complications with collateral and payment terms. But if I had an interest in the person needing the money, or in the particular business, I might give it a try.
“Can you afford to lose some or all of this investment?”
Yes.
