Contractors vs your own team

[Mark Sokolowski]

I have almost 200 units that i own which means that at least once a month i have a vacancy that needs to be gut renovated (usually about 2-3 a month) i have a set of 4 construction companies ready to redo the apartment. people have told me its a lot easier to have your own construction team. How do i go about doing this? anyone else do this? how much will it save me? lets say i dont have any vacancies in a certain month?
