Send them a bill for the situation and if they don't pay tell them your sending the invoice to a collection agency that will call them constantly till they pay. 

Done right, this can get you economy of scale and some favorable pricing (i.e. less than what you'd paid to roof a single family home of comparable size).The down side can be things like agency costs, poor management, and financial mis-steps.The bottom line: what are you getting for the dues?

Hello BP,My name is Alex Hamilton and I work for a tenant screening agency that helps property managers qualify prospective renters.

Maybe it's different if the "extra" money is coming from an assistance agency like SAVE. 

I'm currently a VP Creative Director at a top Advertising Agency in New York City.

I have know received a letter from the collection agency saying they'll report it to a credit bureau unless I get in touch with them in 10 days. 

The other two options: Cash for Keys (which you tried once... try again) and Services for the Homeless/Social Service Agency Guidance (provide a list of resources in your area in which he may engage.)
