A client I consulted with a few months ago hesitated until the last moment before signing a contract for a rental unit purchased in Glenview, worried about the potential for a long vacancy period. Simply saying that it's a good school district didn't reassure them. What they needed to confirm before making a decision was not vague expectations, but the actual rental rates and demand.

Looking at the recent market, the average monthly rent in Glenview is around $2,457 (as of November 2025, RentCafe). This is a 3.24 percent increase from a year ago, with two-bedroom units exceeding $2,694 and three-bedroom units going over $3,841. Observations indicate a steady interest from family-sized tenants, thanks to the good reputation of the school district. However, since school district boundaries change frequently, it's advisable to check the assigned school for the specific address before purchasing.

Investment property loans typically require a higher down payment than primary residence loans, usually between 15 to 25 percent, and while a credit score of 620 is sufficient to qualify for a loan, a score above 740 is needed to secure favorable interest rates (fanniemae.com, freddiemac.com). Interest rates are generally set 0.5 to 0.75 percentage points higher than those for primary residences. Rental income is only counted as 75 percent of the expected rent by lenders for qualification purposes, so it's wise to prepare the lease agreement or appraisal rent schedule in advance.

Illinois prohibits counties or cities from implementing rent control under the Rent Control Preemption Act established in 1997 (hemlane.com). While there is no cap on rent increases, it is not allowed to raise rents multiple times within a 12-month period for month-to-month leases. Tax and rental laws may vary by county, so it's important to verify these details before signing a contract.

The property tax burden is a variable that can be easily overlooked in Cook County, where Glenview is located. The average effective tax rate in Cook County is about 1.91 percent (smartasset.com), but some townships may have rates as high as 3.5 percent (jvmlending.com). If you are moving from another state, it's safer to look at the actual tax amounts assessed and the potential for changes based on local government budgets rather than making simple comparisons based solely on tax rates.

There is an industry rule of thumb that suggests if the monthly rent exceeds 1 percent of the purchase price, the cash flow is likely to be healthy. In areas like Glenview, where the median prices are high, it can often be challenging to meet this benchmark, leading many investors to focus more on long-term capital appreciation than on monthly cash flow. The cap rate, which is the net operating income divided by the purchase price, is also a useful metric for comparing profitability with properties in other areas.

Management costs should also be factored into your calculations.

• 8 to 12 percent commission on monthly rent for property management services
• Maintenance costs of about 1 percent of the asset value annually
• Landlord insurance typically costs more than standard homeowners insurance due to broader coverage

If you plan to sell this property later and switch to another rental asset, consider looking into the 1031 Exchange program. This allows you to defer capital gains taxes by reinvesting in like-kind properties, and you can check the requirements on the IRS website (irs.gov). However, the exchange deadlines and procedures can be complex, so it's advisable to consult with an accountant in advance.

The client who was worried about vacancies ultimately proceeded with the contract after verifying the rental data for the past 12 months. The demand confirmed by the numbers became the basis for their decision.
