Joliet's 0.6% rent-to-price ratio is well below the 1% rule. At median prices of $340,000, the $2,130/mo rent produces only $1,196/mo in NOI. Investors here need to target below-median properties or pursue value-add strategies to make the numbers work.
At current rates, a 20% down conventional loan ($68K at 7%) would result in approximately $-613/mo cash flow — negative at median prices. Larger down payments, seller financing, or buying 15–25% below median are strategies to turn the numbers positive.
Property taxes consume 27% of gross rent here — one of the highest ratios in our dataset. This significantly compresses margins and makes Joliet a market where tax-conscious underwriting is essential. Every deal should be stress-tested with potential assessment increases.

Joliet, IL has a population of 151,000 and has been growing at 0.4% annually — roughly in line with national trends, meaning demand is stable but not exceptional. The median home price of $340,000 paired with median rents of $2,130/mo produces an estimated cap rate of 4.22%.
Property taxes at 2.06% are notably high and represent a significant drag on cash flow — model this expense carefully, as it can make or break a deal. The vacancy rate of 5.8% is moderate and within normal parameters for a healthy rental market.
At a price-to-income ratio of 5.0x, homes cost about 5.0 times the local median income of $68,200. This moderate ratio indicates a balanced rent-vs-buy market. Home values have appreciated at roughly 2.2% annually. Steady appreciation means total returns will be primarily cash flow-driven — the more sustainable model for long-term wealth building.
Bottom line: Joliet presents moderate opportunities. Cap rates near 4.22% mean deals need careful sourcing — look for value-add rehabs or emerging neighborhoods where rents are climbing.
