LA Times - "What's really so bad about rental units in a condo complex?" (7-2-06)

"Our condo complex is 19% rental units. I want our association to prevent the future purchase of units intended to be rentals. I want the board to require a buyer to live in the unit for two years before it can be rented. I've heard that mortgage companies can refuse to finance condos and homes if more than 25% of the complex is used as rentals. Some of the other owners don't share my concern, but I'm worried about lowering property values. Can our board legally cap the number of future rentals while permitting the existing rentals to stay?"
