Look up '36 Yogananda Street'. That is (was) Nancy Lanza's house. Shows two entries, first 02/08/2011 (0), then 02/01/2013 (0)..
I think the database is incomplete, however.
The other thing that’s weird is that in some cases the volume and page numbers of the 0 entries are duplicate entries of others. A mortgage release or other transaction can’t have the same volume and page number of the preceding transaction. Doesn’t make any sense.
My house actually has a zero entry on it. I can tell you I pay my mortgage every month.
