$900,000 Chicago family neighborhoods in reach
Kenwood
The single cleanest fit. Linda's commute is shortest here, the high school is the strongest non-lottery option in CPS, the demographic mirrors the family, and budget buys actual single-family inventory. The elementary question is real — but solvable. This is #1.
Pick 2Hyde Park
If they win the Murray magnet lottery or self-fund Lab Schools (or qualify for U Chicago faculty discount), Hyde Park jumps to #1 because the commute and walkability are unbeatable. Without that, the zoned elementary is a real unsolved problem. Tour with Murray application status in mind.
Pick 3Beverly
The 'more house, longer commute' play. Best pick if Linda's schedule consolidates (4 days/wk in-person, OR overnight call in a hospital apartment) — the commute math then becomes acceptable. If she stays at 5/wk with rounds at 7am, it's a daily 30-min reality check. Strong #3, but only if commute logistics give.

Illinois (Cook County) property tax for a $900,000 home
Estimated annual tax: $15k–$22k on an $850k home depending on township (Hyde Park ~$18k, Oak Park ~$26k+).
- Cook County uses a triennial reassessment cycle. The City of Chicago (incl. Hyde Park, Kenwood, Bronzeville, Beverly) is reassessed every 3 years; the next city-wide reassessment is 2027. South/west suburbs (Oak Park) are being reassessed in 2026 — Oak Park bills are likely to jump.
- Effective rate = (Assessed value × State equalizer × Local tax rate) ÷ Market value. Hyde Park / Kenwood land at ~2.0–2.2%; Beverly ~2.3–2.5%; Oak Park ~3.4% (OPRF + library + park district + village all stack).
- Homeowner Exemption knocks $10k off Equalized Assessed Value (~$950/yr savings) — auto-renews after first filing. Filing deadline: May 15, 2026.
- Senior, Longtime Homeowner, and Home Improvement exemptions exist but don't apply here yet.
- Always pull the parcel's actual tax bill on cookviewer.cookcountyassessor.com before offering — the headline rate hides huge variance by parcel.
Budget rules for a $900,000 Chicago home
- Maximum offer: $900k on a true unicorn; $850k on a great fit; $750k is the bullseye.
- Keep at least $100k liquid post-close. With one kid in childcare ($2k+/mo) and another starting Pre-K, the cushion is non-negotiable.
- Plan for the 6.4% rate we lock today — not a hypothetical refinance.
- Cook County's effective tax rate of 2–3.5% (Hyde Park ~2.1%, Oak Park ~3.4%) is built in forever. Always model monthly with PITI, not P&I.
- Stress-test on Linda's salary alone ($300k of HHI). If the monthly is >40% on her income, walk.
