An estoppel letter is used in a transfer or conveyance of real property prior to the Closing transaction. The document is sent to a bank (or other lender), to an HOA (or Condo Association), to a city/municipality, or a tenant requesting payoff of a mortgage, assessments or taxes due, or rental amounts due on a lease, to incorporate these amounts into the Settlement Statement for the buyer and seller of the real estate. Assessments and payments due must be incorporated into the amounts due at Closing and paid at the time of the Closing. Some amounts may be pro-rated, but all must be included in the Settlement Statement. The estoppel letter is the document that facilitates this process.

Association management is a distinct field of management because of the unique environment of associations. Associations are unique in that the ‘owners’ are dues-paying members. Members also govern their association through an elected board or other governing body, along with association committees, commissions, task forces, councils and other units. Typically, the board selects, retains and evaluates a chief executive officer or an executive director who is responsible for the day-to-day management of the association and paid staff. Managers within the association environment are responsible for many of the same tasks that are found in other organizational contexts. These include human resource management, financial management, meeting management, IT management, and project management. Other aspects of management are unique for association managers. These include: membership recruitment and retention; tax-exempt accounting and financial management; development of non-dues revenue and fundraising. Association managers must also be familiar with laws and regulations that pertain only to associations. To attain the knowledge needed to effectively operate in association management, its practitioners may choose to pursue the Certified Association Executive designation.

The Declaration is sometimes referred to as the ‘master deed,’ ‘documents,’ or ‘declaration of covenants, conditions, and restrictions’ [CC&Rs]. It describes an owner’s responsibilities to the association which can include payment of dues and assessments as well as the association’s various duties to the owners. It is common viewed as somewhat of a ‘constitution’ of the association. The person or group of persons who either signs the original declaration governing the development and association or acquires the original developer’s rights is referred to as the ‘Declarant.’
