Don't forget about the annual max gift tax limit (15k for 2020). Your father could reasonably gift you 15k a year (possibly another 15k to your spouse if you happen to be married) to reduce his savings a tiny bit quicker, so medicaid kicks in a bit sooner. At that point you could maybe even claim your parent as a dependent, and help him pay for his medical costs (which I think you can also deduct?).

I'm not sure on the particulars, and certainly don't take the above as any kind of financial advice -- I just started looking into this for an aging parent myself. Though, it might be worth talking to an accountant and see what is applicable for your location.
