Django Boolean Queryset Filter Not Working

This has been frustrating me for the better part of an hour.

I have the following model:

sold= models.BooleanField(default=False)

And the following view code:

properties = Property.objects.filter(sold=False).order_by('-created_on');

And the following values in my sqlite3 database:

 sqlite> select sold from clients_property;
1
1
1
1
1

And the following template code DOES work (as in, hides the sold items):

{% if not property.sold %}

Anyone know why the query set filter isn't working or why I'm doing it wrong? I've tried:

sold="1"
sold=1
sold="false"
sold=False
sold="False"
