How to use this index
Multiply the market value of your current home by the index number of the destination city where you plan to move, then divide that number by the index number of the market where your current home is located.

For example: if you presently live in Houston, Texas, in a home valued at approximately $115,000 (and an index number of 50) and are planning to move to Hollywood Hills, CA (with an index number of 229)

$115,000 x 229 ÷ 50 = $526,700.

To replace a $115,000 home in Houston with a comparably sized property in Hollywood Hills, CA, expect to pay about $526,700.
