Naturally if you break it down by unit type your sample size shrinks and degree of error goes up.
On our analysis we used 1000 units broken down by unit type and the glaring differences in turnover became obvious.(low 40% for 1, 2 and 3 bedroom, and 119% for studios) It's hard to understand that no one in the industry seems to have had the presence of mind to do the same. We don't need to give incentives to 1,2 and 3 bedrooms, but we certainly need to consider retention program for studios. Without this analysis, (even with a decreased sample size) we would be throwing money all over the map rather than focusing our efforts. Hopefully these large analytical organizations will, in the future, break down turnover by unit type so we too can better understand the national numbers and use them to help set our target rates.
