Common Mistakes in Underwriting Taxes
- Ignoring the Equalizer: The State Equalization Factor fluctuates annually to ensure uniform assessment across Illinois counties. It acts as a massive multiplier on raw assessed value.
- Assuming Trailing Taxes: Underwriting based on last year's tax bill in a reassessment year is a fatal error, especially as the Assessor actively targets commercial assets.
- Misunderstanding Vacancy Relief: Getting vacancy relief from the Board of Review is not automatic and requires strict documentation of attempts to lease.
