I have noticed that some of us seem to keep our models for different lengths of time.
Many reasons are given, some have limited display area, some have limited storage,,,,,,,while others have as much display and storage as they need.
I know of one famous modeler that pretty much keeps his models until he gets the photos taken, then they go off to display cases or as gifts. Another guy builds his, puts one out for people to see, and then boxes them up for attic storage, taking them down only if he wants to post a photo or go to a show.
To answer my own question, I have to keep mine for at least another decade, since I want to someday have VF-1 sitting on the shelves with VA-216, and all the squadrons in between. That does affect my building style somewhat. For example, I can't use any White that has proven to yellow over the years, or I will wind up with two aircraft from the same cruise from different squadrons with different underside colors.
And I have Nooo interest in building VA-12 three different times because the models don't hold up until the collection is finished.
How long do you keep your models?
