I'd go with Singapore as an example and suggest government-managed Skyscrapers. Lots of units and everything is standardized so you get the best possible bang for your buck. It also makes moving around pretty easy if both houses have the same landlord and similar units and similar prices.

"In Singapore, nearly 80% of the population resides in housing that is developed and managed by the Housing and Development Board. Units are owned, however, by tenants. The government, following a land-lease system common in other city-states, owns the land and leases it out for 99 years to these unit owners."
