Building an Orland Park homebuyer tax research file
Construct a thorough property tax research file for your Orland Park home purchase, covering county tax records, exemptions, and assessment expectations.
The short answer
Homebuyers in Orland Park must actively manage two potential tax jurisdictions: Cook County and Will County. To build an effective tax research file, you should identify which county your property resides in, access relevant assessment records, and investigate potential homestead exemptions to understand your long-term ownership costs before finalizing your purchase contract.
Identifying Your Jurisdiction
Because Orland Park spans both Cook and Will Counties, your first step is verifying your specific county jurisdiction. Each county maintains its own assessment directory and tax portal, which will dictate your tax bill calculations and exemption eligibility.
Worksheet: Look at your property’s legal description or tax bill. Note the county name and access that county's official website to locate their specific property tax resources.
Researching Property Taxes and Assessments
Tax bills are determined by the equalized assessed value (EAV) and local district levies. By accessing Will County or Cook County portals, you can view the tax history of the property and understand how previous assessments were calculated.
Planning Example: How can creating a comparison table using the last three years of tax bills, including the EAV and total taxes paid, help you forecast your own future budgetary requirements?
Identifying Tax Exemptions
You may qualify for a General Homestead Exemption if you occupy the property as your primary residence. Other exemptions, such as those for seniors, veterans, or persons with disabilities, are available and require application.
Professional Inquiry: Ask a tax professional or the county assessor’s office how long it typically takes for an ownership change to reflect in the application status for your specific homestead exemptions.
Understanding the Closing Process
Mortgage closing involves significant paperwork, including your Closing Disclosure. Ensure your tax research file is ready to share with your lender, as they will need accurate tax information to determine your escrow and insurance requirements.
Planning Example: Why should you keep a checklist of reviewed tax records, and what steps should you take if your research reveals an unrecorded exemption?
Checklist
- Verify your home's county (Cook or Will) via official maps.
- Access the county’s property tax portal to view tax history.
- List all potential exemptions for which you may qualify.
- Review the property’s current EAV and assessment status.
- Coordinate with your lender to include tax estimates in your budget.
