Questions

What is a constant-quality index?

An index that reprices a fixed basket of homes, so it moves only when prices change and not when more large or more central homes happen to sell.

What is a factor premium?

The percentage price-per-m² gap between two otherwise identical homes that differ by one stated unit of a characteristic, such as more floor space or a better energy rating.
