Buy land in the good places and sit on it until the land and property has gone stratospheric. Aim to never increase supply to the level the market needs to maintain prices; instead constantly force up asset prices forever until you essentially have two classes of people, renters and owners. Keep splitting the housing into smaller and smaller units, make the renters share housing, constantly increase prices at more than the rate of inflation. Only sell newly created housing at a huge premium above market rate.
Buy more land and more property. Rinse repeat.
