ASK Everyone: How to describe major purchases in 3 words or less?

Hey everyone, I am working on the YC application. I am trying to describe complex/major purchases in 3 words or less.

Some examples of major purchases would be: -A CAR -A Mortgage -A Boat -A Web Designer -A Consultants Services

Anyone know of a way to put it in a nutshell?

I've got "services/major purchases/commitment based decisions" so far, can anyone condense that? It seems way to long.
