Why would you not hedge the underlying instead (the house) with a property derivative: https://www.ipf.org.uk/asset/B6F9B2DA-EECA-4799-8BBED392CCC9CCE1/
It’s a hard question. Of course, you could try, but such a plan can also be a disaster for you. I suggest sifting everything through, even with a professional advisor.

I think the problem is you are trying to hedge against a move that has already happened and you needed to hedge when you took out the loan. Assuming it is a 5/1 ARM , OTM puts would have been absolutely dirt cheap in 2020 and you would have had a huge cushion for the correlation to not be perfect. I agree with Murray that you just have to pay it down.
