There are plots of land that are owned by individuals or businesses that have been purchased for future use without (e.g. dowry, future residential building for own use, commercial exploitation, etc) but without any current indication of what its use will be. It is a form of investment without any current indication of its exploitation. These plots of land are usually in the form of additional collateral for personal loans or business loans.

Can these be recognised as commercial real estate collateral under article 126 if all minimum requirements are satisfied?

The answer in Q&A 2014_1214 in short states that commercial real estate can be any immovable property that is not residential but it should be linked to an economic activity.  

Additionally under BIS 10.2 par. 69"A commercial real estate exposure is an exposure secured by any immovable property that is not a residential real estate".

This question has been rejected because the matter it refers to has been answered in Q&A 1214.
