Switching to manage my own properties

We usted to run properties through an agency but we are switching to manage on our own.

We have created a New ID, but It is not clear to me  how to proceed.

Some of the properties are under renovation and Will be open on a few weeks by us with a complete New setup so we would like to show them as a New unit.

Other 4 Will be booked by the agency until may 31st but we want to start taking reservations from now on.
