The total stock under conversion is the total projected rentable area (RA) of space at a point in time that will result from projects that are currently under conversion from one real estate asset class / property category to another (e.g. from office space to residential space).
Total stock under conversion is related to the concept of total stock.
Total stock is distinct from projected total stock (a defined future point in time). Think of total stock as being the supply of real estate at the current moment in time. Projected total stock is the current total stock added to the stock that is predicted to be completed by the defined future point in time.
There are other useful terms to consider when exploring the dynamics of a real estate market. Vacant space, nominal vacancy rate, structural vacancy rate, shadow space, expanded vacant space, delivery, on hold, stalled development, abandoned development and pipeline entries. These are all important concepts that form the makeup of real estate supply and demand.
