Learn moreA real, disclosed cross-source price spread
Crystal Lake's median home value was cited at approximately $311,400 by one source and approximately $285,000 (April 2026) by another -- a real, disclosed spread this record states honestly rather than resolving with false precision.
A genuine affordability advantage relative to the North Shore
Either figure runs genuinely, substantially below Highland Park's $809,080 average value and Lake Forest's $1,014,876 typical value, both documented elsewhere in this project's Illinois Tier B batch.
A real, elevated carrying cost worth understanding
Illinois assesses property at a fraction of market value, so Crystal Lake's composite rate against assessed value (roughly 7.72% in some McHenry County taxing-district compositions) looks much higher than its effective rate against full market value (2.57%) -- both describe the same real burden, and buyers should understand which figure they're seeing before comparing markets.
Key takeaways
- Median home value: approximately $285,000-$311,400, a real, disclosed cross-source spread.
- Crystal Lake's home values run genuinely below the North Shore's Highland Park and Lake Forest.
- Illinois's property assessment mechanic (assessed value versus market value) can make Crystal Lake's tax rate look inconsistent across sources -- confirm which basis a given figure uses.
- Confirm current, address-specific pricing directly given the disclosed cross-source spread.
