What is a "VvE" of "Vereniging van Eigenaars"?

The Vereniging van Eigenaars is a Dutch version of a home owners association and membership is mandatory when you buy an apartment. The VvE manages the care of the building and serves the owners' communal interests including issues like maintenance and insurance. All VvEs are bound by Dutch rules and regulations and many mortgage parties have strict rules the VvE has to comply to before a mortgage is provided.
