Just a word of warning, if a president is not elected by the purchasers one will be selected at random (by drawing lots) by Ammex as per the "Horizontal Property Act"
"This selection will be compulsory although the unit holder may apply to the courts to have this annulled." It is up to a Judge to decide whether this person will carry on as president!
The full version of the Horizontal Property Act can be found on the Ammex website.
Also as per the info i have read, you only get one vote as an owner regardless of how many properties you own in your community. Therefore if Interlaken own 15 apts in PM2 they only get one vote.
