Here's a house on Zillow, with the house number clearly visible. https://www.zillow.com/homedetails/26387-Isabella-Ave-Carmel...
Google Maps https://www.google.com/maps/place/26387+Isabella+Ave,+Carmel...

There is something fishy though.
Searching for the address in Bing Maps shows the correct structure, but I can't seeem to generate a link with the address. The link is lat long. https://www.bing.com/maps?cp=36.54084%7E-121.930825&lvl=19.7
Open Street Maps address queries don't seem to work, and when I select that location on the map, the geocoded address is incorrect but close. https://www.openstreetmap.org/directions?from=36.54084%2C-12...
What Carmel needs are affordable addresses, but that's a different problem entirely.
