There have been a handful of successful en-bloc sales around my neighborhood, including one particularly lavish development on freehold land. I remember because it was a big deal at the time - the residents sold the land to a prominent local developer known for their luxury projects. The sale made headlines in the real estate sections of most newspapers, and it appeared that the residents did make a pretty cent from the sale. If I recall correctly, some of the older residents used the opportunity to upgrade within the development, while others retired to smaller homes elsewhere, so they could cash out on the rise in property value.
