Have him sign the condo over to you and your sister then they can't take it and then when the market is better sell it and put the money in a bank account for him to use but not in his name so they can't take that either. Then at least he'll have money for comfort items. As a long term care provider I can assure you that most everyone with lucid thoughts wants to go home. It is completely normal to want the comfort and security of 'home'...most adjust after a while when they get used to the new routine and find some people they get along with and figure out which staff are better than others...also when he gets a permanent placement bring in some of his favorite items to make it feel more homey and some places allow dorm fridges in rooms to stock with personal snacks and such...also visit often during recreation events to help get him interested in activities being offered and if he's able take him out for visits once he is settled in. Also let him know that while he is capable of doing all his own stuff (and most nursing homes will let him do his own care if he is able) you and your sister feel it is better that he have 24 hour care in case of emergencies so as to ease the stress in your lives of constantly worrying about his safety...perhaps if he sees it is better for you guys in the long run he'll be better able to handle the changes.
