Who Rents In DuPage County

DuPage County's apartment demand starts with its 94,284 renter households, 26.9% of all occupied homes in the county (U.S. Census ACS 2020–2024). Renter households rose 3.3% over five years while population grew 0.1%. More of DuPage County's residents are renting than before.

The typical DuPage County household earns $112,096 a year, 20.8% more than in the 2015–2019 survey. The number of employed residents fell 1.4% over the same period, and unemployment stood at 4.9%. Because rent (28.3%) outpaced income (20.8%), affordability is tighter than it was five years ago. That favors buildings priced below brand-new product.

Most households in DuPage County own their homes, so the renter pool is smaller. Good apartment buildings can still lease well here, but there are fewer of them to buy and fewer recent sales to price against.

Median gross rent in DuPage County, IL is $1,688 a month, up 28.3% from $1,316 in the 2015–2019 survey (U.S. Census ACS 2020–2024). Few markets grew rent faster over the period. We still underwrite slower growth from here, because rent spikes tend to cool once new supply catches up.

At 5.6%, DuPage County's rental vacancy rate sits in a normal range. 45.1% of renters spend 30% or more of their income on housing. That is close to the national picture, where roughly half of renters do, so rent increases need to track local wage growth.

The median home was built in 1978, so many apartment buildings date from the 1970s and 1980s. That vintage is a common target for value-add renovation. For comparison, HUD's fiscal year 2027 Fair Market Rent for a two-bedroom unit in the Chicago-Joliet-Naperville, IL HUD Metro FMR Area is $2,011 a month.

Can Tenants Afford DuPage County Rents?

At $1,688 a month, the median DuPage County rent adds up to $20,256 a year, or roughly 18.1% of what the median household earns. Under the common 30% guideline, a household needs about $67,500 a year to cover that rent comfortably. That's close to the Illinois figure of 18.3%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

In dollars, DuPage County rent climbed $372 a month over five years and household income climbed $19,301 a year. Rent has outpaced income, so we are careful about how much further a business plan pushes rents on renewal. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $2,011, is 19.1% above the median gross rent for all unit sizes. That gap matters for buildings that accept Housing Choice Vouchers, since local housing authorities base voucher payment standards on it.

What We Look For In DuPage County

Skyline buys 5+ unit apartment buildings in DuPage County that either run well today or can run better with new management or renovation. We start with rents, occupancy and the condition of the building, and we price on what the property earns now.

Property taxes are a big line item for any Illinois apartment building. We underwrite the tax bill after purchase, not the seller's current bill, since a sale often resets the assessment. Illinois has no statewide rent control law, though local rules on notices, fees and deposits still apply. Insurance quotes in Illinois reflect winter storm and frozen-pipe claims, so we get a quote before we make an offer.

After a stretch of fast rent growth, we keep rent assumptions modest and leave room for concessions if new supply opens nearby.

Due Diligence For Apartment Syndications In DuPage County

Whoever the sponsor is, these are the questions we would want answered about any apartment syndication in DuPage County, based on the local numbers above.

• What vacancy does the plan assume? Rental vacancy in DuPage County is 5.6%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 28.3% over five years. Ask whether the plan assumes that pace continues, and what happens to the deal if rents stay flat.
• How was the property tax bill estimated? A sale often triggers a reassessment, so the bill after purchase can be well above what the seller pays today.
• What capital work is budgeted? The median home in DuPage County was built in 1978, so roofs, plumbing and electrical systems deserve their own line items.
• How and when does capital come back? Ask what the plan is for a refinance or sale, and what happens if that takes longer than expected.

How Passive Investing In A DuPage County Apartment Syndication Works

In an apartment syndication, Skyline acts as the general partner. We find the DuPage County property, negotiate the purchase, arrange the loan and oversee management and any renovation. Limited partners put in capital and own a share of the entity that owns the building. They don't sign on the loan or deal with tenants and repairs.

It's a long-term commitment. The property has to be refinanced or sold before most capital comes back, and the outcome isn't certain. Eligibility rules vary by offering, and most are limited to accredited investors. See investing with Skyline Capital for how we work with limited partners.
