Updated 2026 · Based on median market data for Naperville, IL
Naperville sits in the Midwest with a population of 150,000 growing at 0.5% annually. The median home costs $440,000 while rents average $1,950/mo, producing an estimated cap rate of 2.29%. Cash flow investing here requires creative strategies like BRRRR or value-add approaches.
Naperville works best for experienced investors with a clear strategy — Section 8, student housing, or deep value-add rehabs. The 2.29% cap rate at median prices is tight, so success depends on buying below market, forcing appreciation through renovation, or accessing above-market rent streams through niche tenant bases.
Target properties priced 15-25% below the $440,000 median — around $352,000 or less. At this price point with $1,950/mo rents, your cap rate improves to roughly 3.6%. Factor in 2% property taxes ($8,800/yr), budget 5% of gross rent for maintenance, and underwrite to a 4.2% vacancy rate. On a 20% down conventional loan at 7%, monthly PITI will run approximately $3,174.
Property taxes at 2% are notably high — this is a significant drag on NOI that some investors underestimate. Higher price points mean more capital at risk and tighter cash flow margins — ensure you have adequate reserves. Every deal should be evaluated individually using our calculator tools.
