French to English Tech/Engineering Education / Pedagogy

I know there are two terms here, but I have to post them in a single question as the challenge is how to differentiate between these two FR terms in EN.

Under most circumstances, I would translate "commercialisation" as "marketing". However, I'm working on a property management contract where the two terms seem to have subtly different meanings, and I have a mental block about how to capture the nuance in EN.

An example from the text:

"Commercialisation de tout ou partie de l'Immeuble

Les obligations associées à la commercialisation de tout ou partie de l'Immeuble incluent notamment :

- Mettre en œuvre et coordonner l'élaboration d'un plan marketing et de commercialisation annuelle, avec la coopération des agents désignés par XXXX, qui comportera :

- les principes de commercialisation comprenant le loyer et les frais,

- la stratégie et le programme de marketing incluant le budget"

It seems to me that "commercialisation" here refers to "sales" - i.e. commercial activity resulting in finding tenants for the Property - except that I can't really uses "sales" in EN as the property is being leased and not sold. But I can't use "marketing" either, as that is used separately to refer to classic marketing activity (advertising, promotion etc.).

Toutes propositions seront les bienvenues !
