Estimate an income that is low enough to generate a subsidy which will keep her premium under $200 and a CSR Silver plan. If she ends up earning $90,000 this year, like she did in 2015, have her set aside enough of that $90,000 to repay the subsidy at tax filing time in 2017.
That's how I would advise someone in her situation who really wanted health insurance, but couldn't afford the premium at this time. It's essentially an interest-free ObamaCare loan.
But then you have that pesky little challenge of providing proof of income.
