- Rent has been flat since 2025, holding at a $2,500 median for two straight years after three years of steady gains.

About Grayslake, IL
Grayslake sits in central Lake County with a population of roughly 21,000. The village is served by two Metra stations, one on the Milwaukee District North Line about 41 miles from Chicago Union Station, and one on the North Central Service, which gives renters two separate routes into the city. Two public high schools, Grayslake Central and Grayslake North, together enroll roughly 2,700 students. The largest employment sectors for residents are manufacturing, health care, and education. The housing stock is a mix of subdivision single-family homes and a large share of townhomes, which shapes the rental market in a way covered below.
Grayslake rent trends, 2022 to 2026
Median rent in Grayslake climbed from about $1,900 in January 2022 to about $2,500 in September 2026, a gain of about 32% over the four-and-a-half-year window. Most of that increase landed in a single stretch. Annual medians ran $1,995 in 2022, $2,100 in 2023, then jumped to $2,400 in 2024 and $2,500 in 2025, where they have stayed through 2026.
That plateau is the most important thing in this report. Two consecutive years at the same median, after three years of gains, is the market telling owners that the easy increases are finished. An owner budgeting another 8% bump at renewal is budgeting against the data.
The line above is smoothed to a three-month rolling median because Grayslake closes only six or seven leases in a typical month, and a raw monthly line swings hard on a single unusual lease. The Lake County line is plotted as a raw monthly median because the county sample is large enough not to need smoothing.
When does Grayslake rent fastest?
Speed has changed more than price. The median lease took 15 days to rent in 2022 and 14 days in 2023. It stretched to 20 days in 2024, 18 in 2025, and 25 so far in 2026. Rents stopped climbing and marketing time went up at the same time, which is the ordinary signature of a market finding its ceiling.
Seasonality is sharp and consistent. May is the fastest month at a 12-day median, with April and September close behind at 14 days. December is by far the slowest at 42 days, with November at 28 and January at 24. A Grayslake home listed in December takes roughly three and a half times as long to rent as the same home listed in May.
That gap is worth real money. At a $2,500 median rent, the difference between a 12-day vacancy and a 42-day vacancy is about $2,500 of lost income, which is a full month of rent given away to the calendar. The practical move is to set lease end dates so the next vacancy lands between April and September. A 14-month or 16-month lease is often enough to shift a December turnover into the spring.
The listings that never rented
Grayslake produced 518 rental listings over the window and 394 of them closed. The other 124, about 24% of the total, were canceled or expired without ever renting. That figure is a useful check on the rent numbers everywhere else in this report, because closed-lease medians only describe the homes that found a tenant.
A quarter of listings failing is a middling result for Lake County, and it points at pricing more than at demand. Grayslake homes that are priced correctly rent in a median of 17 days, so a listing that runs months without a lease is rarely suffering from a shortage of renters. It is usually carrying an asking rent set from the county benchmark or from last year's comparable, in a market whose median has not moved since 2025.
The owners in that 24% absorbed a full season of vacancy and then generally relisted lower. Getting the price right in week one is worth more than any concession offered in week ten.
Grayslake vs Lake County
Grayslake makes up about 5% of all closed Lake County rentals, so it is a meaningful slice of the county.
Metric | Grayslake | Lake County | Difference |
Median rent | $2,300 | $2,350 | -2% |
Median days on market | 17 | 20 | 3 days faster |
Median home size | 1,558 sqft | 1,432 sqft | +9% |
Rent per sqft | $1.52 | $1.67 | -9% |
Sample size, 2022 to 2026 | 394 | 7,710 | 5% of county |
The four rows tell one story. A Grayslake rental is about 9% larger than the county norm and rents for slightly less, which means renters get noticeably more space per dollar. That value is why homes here rent about three days faster than the county median.
For an owner, the same fact cuts the other way. The 9% discount per square foot is the price of competing in Grayslake. Owners who price to the county's $1.67 per square foot, when the town supports $1.52, are the ones who end up sitting through an extra month of vacancy.
Detached houses and townhomes track together
Grayslake splits almost two to one toward attached homes, with 272 townhome and condo leases against 122 detached-house leases over the window. Unlike some Lake County towns, the two segments behave alike. Detached houses run a $2,400 median against $2,200 for attached homes, a gap of about 9%, and they rent about three days faster. Rent per square foot lands at $1.62 against $1.50, a difference of about 8%. None of those gaps is wide enough to justify pricing the two segments by different rules, so a single per-square-foot benchmark works across the whole town.
What this means for Grayslake property owners
- Plan for a flat year. The median has held at $2,500 through 2025 and 2026. Model renewals at flat to low single digits. Anything above that is upside.
- Price to $1.52 per square foot. On a 1,558 square foot home that comes to about $2,370. Pricing to the county benchmark of $1.67 would put the same home near $2,600, which is where listings stall.
- Move your turnover into spring. May rents in 12 days and December takes 42. Adjust lease length now so the next vacancy lands in the April through September window.
- Treat 24% as the warning number. Roughly a quarter of Grayslake listings never rented at all. Those owners lost the entire season.

Is Grayslake a good market for rental investment?
