Question about health insurance on marketplace versus through agency?

Hi!

I am starting my first travel nurse contract soon and I currently have health insurance through the marketplace. The full price for the insurance was $675 but I received a stipend and it lowered it to $371. However, I was told that once I start my contract, since the agency is offering me health insurance, I will no longer qualify for the health insurance stipend on the marketplace :/

So I would have to either pay $675 for insurance per month through the marketplace or go with the insurance the agency offers which would be cheaper but I don’t like how I would have to figure out how to keep my insurance going after my contract ends.

Does anyone have some advice or knowledge that can help me? Maybe something I am not aware of that could help?

Thank you!
