Chicago Multifamily Operating Expenses

When someone purchases a Chicago two-flat, three-flat, or four-flat, the financial performance of the building depends heavily on the property's operating expenses. These are the ongoing costs required to own, operate, and maintain the building.

For new investors or buyers who are planning to live in one unit while renting the others, understanding these expenses is extremely important. Rental income may look attractive at first glance, but the real profitability of a building depends on the relationship between the income it generates and the expenses required to keep it running.

This guide explains the most common operating expenses associated with Chicago multifamily properties.

What Are Operating Expenses?

Operating expenses are the costs required to operate and maintain a rental property. These costs occur regularly while the property is being owned and rented.

Operating expenses typically include things like taxes, insurance, maintenance, and utilities. They do not usually include mortgage payments. Instead, they represent the cost of keeping the building functioning as a rental property.

When evaluating a Chicago multifamily property, buyers often subtract operating expenses from the rental income to determine the building’s Net Operating Income (NOI), which is one of the key financial metrics used in real estate investing.

Property Taxes

Property taxes are usually the largest expense associated with owning a Chicago multifamily building. Taxes are assessed by Cook County and can vary significantly depending on the location of the property, the assessed value, and local tax rates.

Buyers should always review the current tax bill and determine whether the property may be reassessed after a sale. In some cases, property taxes can increase after a purchase if the assessed value changes.

Understanding the tax history of a building is an important step when evaluating its financial performance.

Insurance

Insurance protects the property owner from financial losses caused by events such as fire, storms, or liability claims. Multifamily buildings typically require landlord insurance policies rather than standard homeowner insurance.

Insurance costs may vary depending on the age of the building, construction materials, location, and the amount of coverage required.

Older Chicago buildings sometimes have higher insurance costs because they may contain older electrical systems, masonry structures, or aging roofs.

Utilities

Utility costs depend on how the building is configured. In some buildings, tenants pay their own utilities directly. In others, the landlord may be responsible for certain services.

Common utility expenses may include:

• Water and sewer
• Garbage service
• Gas for heating common areas
• Electricity for hallways or shared areas

Understanding which utilities are paid by tenants versus the landlord is an important part of evaluating a property.

Maintenance and Repairs

Maintenance includes the routine work required to keep the building in good condition. This might include fixing plumbing leaks, repairing appliances, painting, or replacing damaged fixtures.

Chicago’s climate can also contribute to maintenance costs. Snow removal, roof repairs, and exterior masonry work are common expenses for multifamily buildings in the area.

Owners should budget regularly for maintenance because even well-maintained buildings will require repairs over time.

Capital Improvements

Capital improvements are larger upgrades that extend the life of the property. These expenses are different from routine maintenance because they involve replacing major components of the building.

Examples include:

• Roof replacement
• Boiler or furnace replacement
• Window replacement
• Major plumbing or electrical upgrades

These improvements can be expensive but are often necessary for maintaining the value of the building.

Property Management

Some property owners choose to manage their buildings themselves, while others hire professional property managers. Property management companies typically charge a percentage of the monthly rent collected.

For small multifamily properties such as two-flats and three-flats, many owners choose to manage the building themselves to reduce expenses. Larger buildings are more likely to use professional management services.

Vacancy and Turnover Costs

Vacancy occurs when a rental unit is empty and not generating income. Even well-managed buildings may experience occasional vacancies when tenants move out.

Turnover costs may include cleaning, painting, advertising the unit, and minor repairs required before a new tenant moves in.

Smart investors usually budget for some level of vacancy when analyzing rental properties.

Estimating Expenses for Beginners

For people who are new to multifamily real estate, estimating operating expenses can be challenging. A common rule of thumb used by many investors is that operating expenses may range between 30 percent and 50 percent of the building’s gross rental income, depending on the property and how utilities are structured.

However, every building is different. Older properties may require more maintenance, while buildings with separate utilities may have lower operating costs.

The best approach is to review actual expense records whenever possible and consult professionals when evaluating a property purchase.
