Quote from Jayford:
Guys,
Although the CPI is a joke, especially "core" CPI, home prices are not in the formula because a drop in prices only effects those who are buying and selling, as most people have fixed loans. Most people don't do this often.
Rents, on the other hand, move up and down more rapidly, and thus has a greater effect. This is why they do this.
