Watch the parcel year-round.

Property tax is seasonal and the season is short. Monitor does the watching: it runs the check the night your county's roll drops, checks your exemptions, and drafts the packet before you've opened the notice.

April
Notice-drop alert
The morning your county posts notices, an email with your new market value and the verdict already run.
April
Exemption check
Homestead, over-65, disability: if one that should be on file isn't, you hear about it before the deadline.
April
Auto-drafted packet
If you're over-assessed and a protest would lower the bill, the packet is built and waiting in your dashboard.
May
Deadline reminders
Three emails before May 15 if you haven't marked the protest filed.
October
Bill check
One email when bills go out, asking whether the number matched what you settled on.
