Each individual landlord is not mechuyav to lose money by taking the Ani in or allowing him to stay without paying (Pashut).
Now the question is do we support such a family so that they can stay in the community? I would think yes, but it goes together with all of the rest of Hichis Tzedaka and Kedima. Does he go before paying your child’s tuition? How about telling a Kollel guy to get a job because we need your salary to pay this guy’s rent?
I believe the Shulchan Aruch YD 253:1 applies as well. If someone is asking to be supported in public, then he needs to sell his items first.
uneeq: I could not find it after looking quickly, so I ask if anyone here can help.
