I agree with you, and to give some numbers as examples for other readers to respond to, I've seen good individual health insurance in the $500-1200 range, and there may be tax advantages associated with paying it. That's not a huge amount per year if you are getting the $30-60k hypothesized interest income.

You're right. After doing some research I could actually pull it off, but it would be pretty tight.

There's some decent insurance options for ~$700/mo. That's still $8400/yr. With $60k/yr income, that might still be doable but I don't think it's realistic on a $30k budget.
