Somewhere between mid-August and late October, a postcard-sized envelope from your township assessor is going to land in your mailbox. Most people glance at it, feel a flicker of annoyance, and file it away. That's the moment that actually matters — because the day it's published starts a 30-day clock, and once that clock runs out, you're stuck with the number for another year. |

This week, no data mythbusting — just a practical guide to when your notice is coming and what to actually do with it. |
| When Your Notice Actually Arrives |
DuPage's nine townships each publish their assessment rolls on their own schedule — it's not one countywide date. As of this week, the county hasn't posted 2026 publication dates yet, but the pattern below reflects last cycle's timing for the five townships that cover this corridor. |

Is It Actually Worth the Effort? |
 How Does Your Town's Growth Compare?Your assessment is supposed to track what homes in your township have actually sold for — not what the county feels like charging. Here's the rolling 12-month median sale price growth across the corridor, straight from MRED. If your assessed value jumped roughly in line with your town's number below, that's a normal reflection of a strong market. If it jumped noticeably more, that's worth a closer look at your property record card. |

| The Bottom Line You don't need to do anything today. But you do need to know which township you're in and roughly when to expect your notice, so a 30-day window doesn't quietly close while you're not looking. And now you've got a real number to hold your notice up against — not a Zestimate, not a gut feeling, but what homes in your own town have actually been selling for. If you're not sure which township covers your address, want a second set of eyes on your notice when it lands, or just want to see how your specific block compares to the corridor numbers above, I'm happy to help — this isn't a sales pitch, it's just useful to have someone who watches this stuff track it with you. |
