Powayseller, don’t know what you mean, but I’ll tell you what I found:
Looked up my mom’s street and noticed that there was a separate listing for her husband. He is not listed on her title. The only hint that there is something different is that all the Parcel No’s on the street start with the same three numbers, whereas his listing starts with a different three numbers.
Then I went to his property’s street and he is not listed there.
Don’t see any category titled Unsecured, he’s just listed right along with all the other’s on my mom’s street.
The point is that it may not be quite so obvious what the property tax status is on streets when the properties are not owner occupied.
