Especially those with very pricey condos and apartments in large, luxurious urban high rises.

The land doesn't use much in public services. Put a house and the needed infrastructure on it, throw in the maintinance on that infrastructure, like roads, water, sewer, trash collection, fire protection, law enforcement protection, civil regulations to keep them safe and protect their individual values, like zoning and such. ALL that is what really costs local government and need to be supported by a solid, reliable tax base.

The land doesn't require a lot of expenditure, until you put the home on it.
