There are quite a number of nepalese family lives in NH. And as u said most family atleast look for keeping at least one mental or disabled ppl. I believe they call them client. There is no state tax in NH and houses are not that expensive although I heard property tax is high. But if u r getting 10k per month u can easily afford a moderate house. The only problem is someone needs to be 24 hour around with their client. One time I saw a guy taking his client to restroom together in a party. If u feel happy abt it and don't mind taking care of such patient then u r OK. But imagine if ur whole family wants to go to vacation for few weeks or to nepal, then ur life is screwed.
