Home Value accesses the vast database of home values maintained by Zillow.com. You can provide a full address or simply ask for your home's value. If Alexa has difficulty translating a street name then try spelling it out (E L M for Elm, etc.) or if it can't find a number address or street then make sure to say it as a number (say 229 as two hundred twenty nine instead of two two nine).
“Alexa, ask Home Value to find 1600 Pennsylvania Avenue Northwest Washington... ”
