Since the bottom of the recession in 2009, we estimate that market rents have grown at a 5% growth rate. However, if you measure from the previous peak in 2008, rent growth as of December 2017 is only 2.25%. I assert that the peak to peak measure is a more accurate reflection of long term rent growth. Based on a 38 year internal rent study, Los Angeles apartment rents have grown over 4%. However, that time period includes many high inflation years that distorts the number upwards.
