What Is Your Libertyville, IL Home Worth Today?

In Libertyville the variable an algorithm cannot see is whether the address sits inside village limits. Homes with a Libertyville address outside the village pay a different mix of taxing bodies, and that affects value.

A Zestimate is an automated model built for scale, useful as a rough bracket. Your county assessed value exists to apportion tax and is deliberately not market value; Lake County assesses at one third. A broker's comparative market analysis uses verified recent sales of comparable homes and adjusts for what makes yours different. Only the third one is a valuation.

Libertyville's value is concentrated in two things a model reads badly: walkable distance to the downtown and to the Metra station. The median sale price was $651,000 in the three months to July 2026 on Redfin, with Movoto at $649,900 and Zillow's index lower at $635,028 because it estimates all homes rather than measuring sales.

Distance to the station falls off faster than most sellers expect, and a comparable half a mile further out is not the same comparable. We adjust for it explicitly rather than averaging it away.

One forward-looking factor no model holds: a 91-unit apartment building was approved at Lake Street and Brainerd Avenue in April 2026. It changes supply near the station over the next few years, which matters if you are deciding between selling now and holding.

Worth checking too: homes outside the village limits pay a different mix of taxing bodies, so the rate on a nearby listing may not be the rate on your bill.

Libertyville's median effective rate is 2.35%, and it is not uniform across the village.

Assessed value exists to apportion tax, not to value your house. Illinois assesses at one third of market value outside Cook County, so multiplying your assessed value by three gives a rough check on whether the assessor's opinion is in the right area. If it is materially above what the house would sell for, that is grounds for an assessment appeal, which is a separate exercise from a valuation and runs on the county's township calendar.

What the bill does tell a seller is what a buyer will be underwriting. At Lake County rates the annual tax is a large part of a buyer's monthly payment, and two houses at the same price with different bills are not the same purchase.

A valuation is a conversation, not a document you receive and file.

If you are selling, the output is a price strategy: a number, the comparable set behind it, what happens if the first two weeks are quiet, and a net sheet so you know what the number means in proceeds.

If you are refinancing or appealing, the output is different. A lender's appraiser and a Board of Review hearing want different evidence from a buyer, and the useful comparable set is not the same one.

If you are simply curious, the honest answer is a range and the two or three things that would move you within it. That is a legitimate reason to ask and there is no obligation attached to it.

Recent closed sales within a tight radius and time window, adjusted for lot size, square footage, condition, updates and tax code. Then current competition and absorption rate. The output is a defensible range with the reasoning attached, not a single number with no working shown.
