Since adjustment of housing consumption implies a costly residential relocation, the household's consumption is usually constant for comparatively long periods of time. Using a model of intertemporal utility maximization, we arrive at conditions for i) the optimal number of moves, ii) the optimal moving dates, and iii) the optimal consumption of housing services and other goods in the period between moves. Specifically, the number of moves will rise with income, the rate of interest, the preferences for housing and the length of the planning period. Furthermore, the number of moves will be higher the lower moving costs are.
