Home values across the North Shore have climbed sharply, and Northbrook sits right in the middle of that trend. For many families, the house is the largest thing they own, which means rising prices quietly reshape what an estate plan needs to do. That connection is easy to miss until it matters.
Where Northbrook Lands
A recent ranking of Illinois cities by home price growth put Northbrook at number 19, with a typical home value near $707,000 after a one-year gain of about $56,000. Over five years, the typical Northbrook home has gained close to $193,000. Neighboring communities climbed even faster. Winnetka, Glencoe, Kenilworth, and Wilmette all posted larger dollar increases, and several North Shore towns now carry typical values well above a million dollars.
The full ranking was compiled by Stacker using Zillow data.
Why This Matters for Estate Planning
Rising values matter for a reason many families overlook. Illinois has its own estate tax, separate from the federal one, and it applies to estates above $4 million. That figure is not adjusted for inflation, and it is not portable between spouses. As home values rise, more families drift toward that line without realizing it.
A single property does not usually cross the threshold on its own. But add a home worth $700,000 or more to retirement accounts, life insurance you own, investment accounts, and other property, and the total moves quickly. Illinois also runs a cliff structure, so crossing $4 million by even a little can trigger a real tax bill, with rates reaching 16%.
The state threshold is set out in the Illinois estate tax fact sheet.
What Pushes an Estate Over the Line
When you add up what most North Shore households actually hold, $4 million is closer than it looks:
- A home carrying years of appreciation
- Retirement accounts built over a full career
- Life insurance you own outright
- Brokerage and savings balances
- A second property or business interest
Steps Worth Considering
None of this means selling the house or panicking over a number on Zillow. It means planning with current values in mind. A revocable living trust keeps a home out of probate and gives the family a clear framework to work from. A credit shelter trust helps married couples preserve both $4 million exemptions rather than losing one. Lifetime gifting can lower the taxable estate over time, and Illinois has no separate gift tax.
The right combination depends on your assets and your family. A Northbrook estate planning lawyer can look at your current home value alongside everything else and tell you whether your documents still fit.

Where to Turn
A home that has gained six figures in value is good news, but it can quietly change what your family faces later.
