10%+ feels exploitative and predatory. The current fed interest rate is 2.5% - 4x above that is "let's profit on the unfortunate".
If it's short term, you end up paying less than 10% on it. If!
That's true, but the only way you'll be able to pay is if once things are rolling again you have that much extra cash. I don't know how tight people live.
Also, it's hard to structure that kind of loan, since you have no idea when repayment might take place. The only comparable thing would be a student loan, where you can defer payments until you have income.
Think of the boost to the economy we will get once these banks report their next quarter earnings!
