In a condo, if an HOA is required to fix plumbing or landscaping, paint, or roofing, then it comes out of the CAM fees paid by the residents. However, if the HOA does NOT pay for that work, or tries to stiff the construction firm they hire, the construction company can take out a lien on the property until their bill is paid.
That lien means you cannot sell your condo until the HOA pays their debt. In my friends case, the HOA had blown all their CAM money on lavish vacations and dinners for key members of the HOA board. They had no money to pay for a sewage repair job, and left 54 members of the housing compex stuck with a $20,000USD repair bill. After a grisly court battle the HOA was disbanded, CAM fees were agreed to be paid directly to the plumbing company for the year, and the complex went into foreclosure after the debt had been paid as most tenants had sold.
