Yes, it is common and right. There is even a term (called a 5407) for this type of requirement. When you go to closing, if you, as the current homeowner, had any outstanding HOA fees or dues, they would become the responsibility of the new owner. Therefore, in order to be fair and legal, that has to be checked out, and put in writing. Many Home Owner Associations employ an outside "management company" who does paperwork. Some smaller ones have volunteers within the community who do the work. IN almost all cases, there is a charge for someone to prepare the 5407 document. In our area, it is common for that fee to be 150.00 or more.
