My 64 year old dad is an alcoholic and needs a place to live, he has lost everything and basically is homeless

1st don't say get him help, he will not take it, once he lived at a state park in his truck to avoid help for alchol but straightened up and started a business then drank it away...my father is 64, he used to have a successful business and wife and has drank it all away losing everything, now he only has 1 month left in his house before it forecloses and he and his dog are homeless... he will not accept any treatment yet he keeps hinting around about showing up at our doorstep jokingly but I know he is serious... I am 43 with a husband no children and we have the room but we do not want to support his way of life which is drinking constantly approx. 24 beers a day, and goes 3 days or more without eating.. what is a daughter to do?? He came to our small town at Thanksgiving and looks so sick and bad, shacking constantly and behaved himself nursing coffee and beer back from 6 am. until bedtime never getting drunk but you could tell he was miserable and it was miserable for us, uncomforat
