Re: home deed and medicare
Because of the way you posted this I am understanding that the acre is in WA; if not, you need an answer from an attorney in the state where the real property is located.
Is your step mother an attorney?
She's offering her legal opinion, intending that you rely upon it. I suggest that you consult with an attorney who handles estate/medicare pay-downs to determine what's the best thing to do here.
I know that medicare is loathe to put seniors on full care when they have resources that could be used for their care.
Has your father considered leaving the property to you in his will? WA is a community property state, which means that IF your father dies before your step-mother, half of what he owns is hers, and the other half is available for him to leave to you (or somebody else) as his separate estate.
I handle real property matters all the time, but when it involves medicare pay-downs, I am going to refer it to a lawyer who handles those questions.
Sorry I can't be more helpful. I wouldn't take your step-mom's judgment as gospel, I'd find out for myself.
Sorry this isn't more helpful, but I hope it helps. Powell
