1250 square feet on two or more levels is a pretty good sized apartment to turn. If you put more than one guy in the same apartment they trip over each other. Cleaning people and fixing people have very different mindsets. If you're expecting the same person to do both, that might be slowing things down. An employee is a tool of management just as a basin wrench is to tool of maintenance. As the old saying goes, "It's a poor workman who blames his tools."
Are we talking JUST maintenance hours, or are you looking for the full turn time - including paint, carpet, cleaning, etc? For a full turn, including those tasks not included in maintenance hours, they yes... 3-5 days to fully turn. My apologies - I thought you were looking for just maintenance hours.
