Building a condominium document file for a Chicago purchase
Establish a comprehensive record of your Chicago condominium purchase by tracking essential property tax, permit, and governing documents.
The short answer
Purchasing a condominium in Chicago requires careful documentation due to the unique interaction between city services and Cook County property tax administration. Buyers should maintain a file containing assessment records, current utility statuses, and any available permit histories. By organizing these documents early, you can better address material defect disclosures and ensure clarity regarding shared property elements and tax obligations.
Tracking Tax and Assessment Data
Cook County residential property is assessed at 10 percent of fair market value, distinct from most other Illinois counties which are assessed at 33 1/3 percent. Ensure your file includes the most recent assessment data from the County Assessor.
Planning Example: Create a folder labeled 'Tax Docs' containing the latest tax bill printouts and any exemptions applied, such as the Homeowner Exemption, to project your future liability.
Understanding Disclosure Obligations
The Residential Real Property Disclosure Act is central to your transaction. While it covers the dwelling unit, it does not explicitly cover condominium common elements.
If you receive a disclosure, review it for any known material defects. Ask the seller for documentation if they claim a defect was previously repaired by a professional.
Managing Closing Paperwork
The closing process involves substantial documentation. Utilize resources like the CFPB's guides on Closing Disclosures to understand your financial responsibilities.
If you have questions about the legitimacy of wire instructions or fee structures, consult your closing professional immediately.
