What These Numbers Mean for Island Lake Buyers and Sellers
The Housing Market Trends module above outlines the core figures for Island Lake, and read together they point to a market where sellers currently hold the stronger position. With a median sale price of $339,830 and prices moving +21.4% year over year, momentum has favored listing owners. The clearest signal of leverage is the sale-to-list ratio of 100.93%, paired with 50.1% of homes closing above their asking price. When most homes clear over list, buyers are competing rather than negotiating discounts.
Supply reinforces that picture. Months of supply sits at 1.4, which is well inside the range typically considered a seller's market, and only 8.6% of active listings have recorded a price reduction. On top of that, 68.8% of homes leave the market within two weeks, so hesitation carries a real cost for buyers. The one counterweight is time on market: a median of 45 days alongside a +7 days change in market time suggests well-priced homes still move quickly while overpriced ones now linger.
For a buyer, this combination argues for coming in near or at list with clean terms on the homes that are priced correctly, while reserving negotiation for listings that have aged past the median. For a seller, the data supports confident pricing, but the widening days-on-market gap is a reminder that the market rewards accuracy over ambition. With 1,615 licensed agents active locally, the difference between a routine sale and an optimized one often comes down to which agent reads these signals correctly.

What to Look for in a Island Lake Realtor
Choosing an agent in Island Lake should start with measured performance, not name recognition or advertising volume. Among the 1,615 licensed agents in the area, EffectiveAgents has ranked 69 based on verified transaction history and client outcomes. The top-ranked team, Jim Starwalt & The Star Home Team at Better Homes and Gardens Real Estate Star Homes, has recorded 3,836 transactions and $953.2M in all-time sales volume. That depth matters in a market where 50.1% of homes close above asking; an agent who understands how to structure competitive offers or price for multiple bids directly affects the number on the contract. Negotiation skill is measurable here, where the sale-to-list ratio stands at 100.93%, and experience across the 60042 zip code helps set realistic expectations for both sides. Review patterns are just as telling as transaction counts. The Star Home Team carries 467 reviews, and a large, consistent review history signals repeatable service rather than a few standout closings. When comparing agents, weigh the volume of feedback alongside the ratings themselves.
How We Rank Island Lake Real Estate Agents
Our rankings are built from verified MLS transaction data, not advertising spend. For every agent we analyze more than fifteen performance signals, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results (how far above or below list price an agent's clients actually close), price-point fit, and verified reviews. The agents shown first are those whose verified results put them at the top of the Island Lake market today.
Agents cannot pay for placement in these rankings. The underlying data refreshes as new closed transactions are reported, so rankings shift with real market performance. Learn how we rank agents.

Island Lake Real Estate Agent FAQs
Who is the best real estate agent in Island Lake, IL?
The top-ranked agent in Island Lake, IL is Jim Starwalt & The Star Home Team at Better Homes and Gardens Real Estate Star Homes, with 3,836 transactions and 467 client reviews. EffectiveAgents identifies leading agents through a data-driven methodology that analyzes verified transaction history, sale-to-list performance, and client outcomes rather than advertising spend.

How were these Island Lake real estate agents ranked?
Rankings are built from verified MLS transaction data. We analyze more than fifteen performance signals for every agent, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results, price-point fit, and verified reviews. Agents cannot pay for placement.
How many real estate agents are in Island Lake?
Our data covers 1,615 real estate agents serving the Island Lake area. The count represents agents with transaction activity recorded in our Island Lake market data, not simply everyone holding a license.
What does the median sale price in Island Lake mean for sellers?
Island Lake's median sale price is $339,830 as of July 2026. Half of recent sales closed above that figure and half below. It is a useful baseline for understanding the market, but an experienced local agent will price your home against comparable recent sales in your neighborhood, not the citywide median.
How long does it take to sell a house in Island Lake?
Homes in Island Lake currently take a median of 45 days to sell, though that figure reflects a +7 days change in market time compared with last year. Accurately priced homes tend to move faster, with 68.8% of listings leaving the market within two weeks, while overpriced or harder-to-show properties sit longer. Timeline is influenced by pricing strategy, condition, seasonality, and how competitively the home is marketed. Working with an experienced local agent who prices to the current data typically shortens the path to a closed sale.
Does it cost anything to use EffectiveAgents?
No. EffectiveAgents is free for home buyers and sellers, with no obligation to work with any agent we match you with.
Do agents pay to be ranked or featured?
No. Agents cannot pay for placement anywhere in these rankings. Positions are earned from verified transaction performance only.
What commission do Island Lake realtors charge?
Commissions are negotiable and vary by agent, service level, and transaction. There is no set rate, and recent industry changes have made commission structures more flexible than ever. Discuss the structure directly with your agent before signing a listing or buyer agreement.
Should I use a local Island Lake agent or a national brand?
The individual agent matters more than the brand on the sign. Offices within the same national franchise vary widely in performance, and the agent you hire, not the logo, prices your home, negotiates your contract, and manages your closing. A strong local agent brings firsthand knowledge of Island Lake neighborhoods, pricing patterns, and buyer activity. Compare agents on verified local results such as recent sales, days on market, and negotiation outcomes rather than name recognition.
What questions should I ask a Island Lake realtor before hiring them?
Ask how many homes they have closed in Island Lake in the past year, what their average sale-to-list ratio is, and how much of their business is in your neighborhood and price range. Ask how they will market your home or find you listings, and how often they will communicate. Strong agents answer with specifics. Verified transaction data is the fastest way to confirm what you hear.
