What does your sqft target cost in Oak Park, Illinois?
$250/sqft median (Redfin)Estimate = (median $/sqft × your sqft) + bed/bath/lot adjustments. Bed and bath adjustments use Appraisal Institute / Fannie Mae standard rules of thumb (~$15K/extra bedroom, ~$20K/extra bathroom vs. a 3bd/2ba baseline; half-bath = half adj). Lot premium is a $1.50/sqft heuristic beyond a 6,000 sqft baseline — accuracy varies sharply by urban infill vs. acreage market. Quality, condition, year built, and HOA are not modeled here.

Educational tool, not investment or real-estate advice. Past performance does not guarantee future results. Backtests use actual annual total returns including dividends from S&P 500 (Damodaran (NYU Stern) annual total return (with dividends), 1957-present.).
Buyer model: 30-yr fixed mortgage, P&I + property tax + insurance + maintenance (1% of value/yr) + HOA. Selling cost = 6%. Investor model: down payment + annual cashflow surplus invested in the chosen index at that calendar year's actual return.
Tax model: pre-tax comparison. Toggle "after-tax mode" to apply MID, SALT, LTCG, and the Sec 121 capital-gains exclusion.
This calculator does not adjust for: PMI (assumed 20%+ down), differential transaction costs by state, lifestyle factors (commute, schools, kids), illiquidity / forced-sale risk, or insurance availability constraints (e.g., FL/CA wildfire). Consult a fiduciary advisor and tax professional before acting on any of this.
Cost-of-living escalation — Illinois (7 categories)
7-yr trajectories · state-grain (no city-grain data published)Trajectories anchor each state's most recent published value to the corresponding national YoY pattern (electricity → EIA, natural gas → EIA, groceries → BLS CPI food-at-home, homeowners insurance → NAIC, healthcare → KFF Employer Health Benefits, auto insurance → BLS CPI motor vehicle insurance, childcare → Child Care Aware "Price of Care"). City-grain data is not published for any of these categories — Oak Park inherits Illinois's state-level series. Per-household costs vary by provider, plan, household size, and usage.

state ZORI mean (city rent unavailable from public sources)City rent data isn't published in Zillow's public CSVs. We use the state-level ZORI mean as the rent reference. The state-level rent is a useful approximation for big metros within a state but can mislead in extreme outlier cities.
