I know of two people that bought in a very high end development in Del Sur recently. I know for sure in one case and am pretty sure in the other case that it was inherited/family/insurance money (parent died). Another family I know was looking in that same development and they also have family money / trust fund sources (although they decided not to buy there after all). Other that that I have NO clue how people do it. I ceratinly could not afford to buy my house house right now.
