Round Lake Beach, IL Housing Market 2026: What Homes Actually Sell For

If you invest in or around Round Lake Beach, the number that matters is what homes actually close for, not what sellers are asking. Here is what Round Lake Beach sale prices look like right now, built from the closings Resideline tracked over the last six months, as of October 2026.

The snapshot

• •Closings tracked, last 6 months: 161
• •Median sold price, last 6 months: $265,000
• •Median sold $/sqft, last 6 months: $195
• •Middle half of sales closed between: $199,000 and $325,000

What the numbers say

Resideline tracked 161 closed sales in Round Lake Beach over the last six months, with a median closing price of $265,000. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. The middle half of those sales closed between $199,000 and $325,000. That spread matters more than the headline median: where a specific property sits inside it decides whether the citywide number helps you or misleads you. These are the closings Resideline tracks and may differ from complete county or municipal records. Across the 160 closings with usable living area, the middle half sold between $163 and $222 per square foot.

The Round Lake Beach angle

Very few closings sit behind this page compared with the markets we track, so read $265,000 as indicative rather than precise. With a count of 161, a single unusual sale can shift the picture more than it would in a deeper market. The band itself is unremarkable: $199,000 to $325,000 is about typical in width. That helps, because it means a widened comp search is unlikely to drag in wildly different sales. Widen carefully anyway. Extend the date window or the search radius before relaxing property type or size, and look at each closing individually rather than trusting a filtered count. Because the lower half of the band is the wider half, be particularly deliberate with comps below $265,000, where the sales that do exist are spread over more ground.

From market read to offer price

A market read is the backdrop. The decision still comes down to one property and one number: what it is actually worth and what you should pay. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator, rehab cost estimator, BRRRR calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale and graded against the real closing price after it sells. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Run any Round Lake Beach address through Resideline and you will see the local market and the property's value together, in one report.

The local market statistics in this report are calculated from closed sales tracked by Resideline. Transaction coverage may differ from complete county or municipal records.

Every local market figure on this page is computed from closed sales Resideline tracked in Round Lake Beach over the last six months, and is refreshed when the data is. The closings we track within the Round Lake Beach city limits are not limited to listing-service sales: they also include foreclosure deeds, estate and family transfers, and other off-market sales that portal medians exclude, which is why 34% of the 161 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $280,000.
