If you are a tenant about to renew your lease or a landlord considering next year's rent, there are three key numbers to look at for Glenview in October: rent levels, mortgage rates, and property tax deadlines.

Let me clarify the reference point. This article is based on data confirmed by November 5, and I couldn't find specific October sales statistics for Glenview. Therefore, I will refer to Cook County figures for the sales trends.

The rent picture can vary significantly depending on which data you look at. RentCafe reported the average rent in Glenview as $2,481 as of November 1, which is $16 lower than the $2,497 from a year ago.

According to the same source, the average rent for a one-bedroom is $2,177, and for a two-bedroom, it is $2,880. The average sizes are 800 square feet and 1,107 square feet, respectively.

However, Zumper reported the median rent in Glenview for October as $2,850, indicating an 8% increase from a year ago. Although it's the same area, one source shows a slight decrease while the other shows an increase.

Looking at Zumper's bedroom-specific data gives some insight into the reasons behind this. The average rent for two-bedrooms has decreased by 14%, and for four-bedrooms, it has dropped by 42%, with a note on the page indicating that there aren't enough active listings.

In neighborhoods with limited inventory, even a few changes in listings can significantly affect the numbers. I don't interpret this level of fluctuation as a clear market direction.

Therefore, if you are a tenant receiving a renewal notice, it's better not to rely solely on the average from one site. Instead, look for two or three similar listings in the same complex or nearby buildings and compare them side by side.

The same goes for landlords. If you only present the 8% figure for a rent increase, tenants may come back with data from other sources.

According to RentCafe, there are 3,893 tenant households in Glenview, making up 21% of the total. Owner-occupied households number 14,555, accounting for 79%, indicating that the rental market is not very large in this area.

In such a market, it's essential to first consider vacancy costs. If you raise the average rent of $2,481 by $100 and the unit sits vacant for a month, that increase would be wiped out in two years.

On the sales side, I looked at Realtor.com data compiled by FRED. The median listing price in Cook County for October is $349,000, which is 5.7% higher than $330,225 a year ago.

However, this figure includes the entire county, which also encompasses Chicago. You shouldn't interpret it as reflective of Glenview home prices or actual transactions.

According to the same data, there were 8,403 listings in October, down 7.7% from 9,105 a year ago. The median time on the market is 36 days, which is not significantly different from 38 days a year ago.

Recent market trends show that inventory is decreasing while listing prices are rising. However, when you factor in interest rates, the burden on buyers is considerable.

Freddie Mac reported that the average 30-year fixed mortgage rate as of November 5 is 7.18%. While this is down from 7.24% a week prior, it is still quite high compared to 6.22% a year ago.

The 15-year fixed rate is also up to 6.57%, compared to 5.50% a year ago.

If you calculate the difference for a $400,000 loan at a 30-year fixed rate, the impact is clear. At 6.22%, the monthly principal and interest payment would be $2,455, while at 7.18%, it rises to $2,710, an increase of $255 per month, excluding property taxes and insurance.

From a tenant's perspective, the urgency to purchase a home has decreased compared to last year. For landlords, it is not easy to reduce costs through refinancing in the current environment.

Don't overlook the property tax deadlines either. According to the Cook County Treasurer's Office, the deadline for the second installment of the 2025 tax year was October 1.

If you're unsure about payment status, you can check directly on the Treasurer's Office website. The site also has information about the tax sale on December 15, so if you have any delinquencies, don't delay.

What about assessments? The Cook County Assessor's Office indicates that this year, the reassessment targets are 17 townships in the southern and western suburbs, while the northern suburbs are not included.

According to the schedule released by the Assessor's Office for Northfield Township, the deadline for appeals was September 4. The assessment roll was made public on October 15, so the assessment phase is complete.

The remaining avenue is the Board of Review for appeal hearings. The Assessor's Office page does not show the dates for Northfield's hearings, so it's quicker to check directly on the committee portal or call 312-603-5542.

Even within Glenview, the township may vary by address, so make sure to verify your home's township first.

Rental regulations can be tricky to determine. Although the village website does not show a rental license item in the license list, that does not mean there are no regulations. The village's main phone number is 847-724-1700.

I also couldn't confirm the applicability of the Cook County Residential Tenant and Landlord Ordinance (RLTO) through official documents this time. Before including clauses about security deposits or late fees, it's safer to ask the county and village, and consult a lawyer for complex matters.

If you are a tenant, here's how to prepare. Gather comparable rental prices and check the lease renewal notice date. Then negotiate the increase.

If you are a landlord, the process is slightly different. Review the assessment roll and tax payment status to calculate vacancy costs. Finally, set the rent.

If it were me, I would opt for a slight increase with a longer lease term rather than a significant hike right now. Keeping good tenants tends to be more advantageous during periods of high interest rates.
