What Holds Up Renter Demand Across The Quad Cities

The Davenport-Moline-Rock Island metro has 45,818 renter households, and 28.3% of its households rent (U.S. Census ACS 2020–2024), the same share as Iowa as a whole. The region is not growing much. Population was flat over five years at 381,503 (up 0.1%), renter households rose just 0.2%, and employed residents rose 0.7%. Median gross rent is $941 a month, up 23.0% from $765 in the 2015–2019 survey and below the Iowa median of $972. Median household income rose 24.3% to $72,738, slightly faster than rent, though 46.6% of renters still spend 30% or more of their income on housing.

The metro straddles the Mississippi River, with Scott County, Iowa, on one side and Rock Island and Henry counties, Illinois, on the other, and its job base leans on manufacturing and government. Deere & Company is based in Moline and runs several plants in the area. In October 2024 it announced about 287 layoffs effective January 2025, citing lower demand for farm equipment. At the time, it had about 1,880 workers at Harvester Works in East Moline, 1,024 at Davenport Works and 625 at its Seeding and Cylinder operations in Moline. Rock Island Arsenal, the Army installation on the island between the cities, was described by Sen. Tammy Duckworth's office in November 2024 as slated to become the region's largest employer. Hospital systems including Genesis and UnityPoint Health – Trinity, Arconic's Davenport Works, HNI and Hy-Vee round out the larger employers, along with Augustana College, St. Ambrose University and Black Hawk College.

For apartment owners, this is a steady, slow market. Demand comes from local plant, hospital and Arsenal workers rather than in-migration, so it tends to move slowly in either direction. A consultant's 2025 Moline housing study noted that regional employment was slightly down, with cuts at Deere. Anyone weighing apartment syndications in Quad Cities communities should look at tenant concentration around specific plants and at how rent compares with local wages.

New Apartments, Old Stock And Rents In The Quad Cities

The metro's rental stock is old. The median home was built in 1967, and the Census counts 26,194 homes in buildings with five or more units, only 15% of the housing (U.S. Census ACS 2020–2024). That count did rise 11.0% in five years, a sign that developers have been active. NAI Ruhl president Chris Beason told KWQC in April 2025 that many apartments had come on the market, with more still in the works, and that a shortage of lower-cost housing had pushed investors toward apartment development.

Much of that building has gone to the Iowa side. In Bettendorf, January 2025 permits included the eight-building, 288-unit Authentix Apartments ($40.7 million) on International Drive, plus the final building at Creekview at Devils Glen. Bettendorf's council approved a 245-unit project near the riverfront, west of the I-74 bridge, in June 2026. Moline has added little. DiSalvo Development Advisors' third-quarter 2025 study for Renew Moline found market-rate occupancy at 93.7% citywide, down from 95.3% in 2020, and counted just six new upscale units downtown since 2020. About nine in ten apartments it surveyed in Moline were Class C or D, with median one-bedroom rent of $843.

The Census rental vacancy rate for the metro is 5.9%. It covers all rentals, including houses and small buildings, so it isn't directly comparable to the occupancy surveys of managed apartments. HUD's fiscal 2027 fair market rent for a two-bedroom in the Davenport-Moline-Rock Island area is $1,056, above the metro's $941 median gross rent.

For a buyer, the main questions are capital needs and exit. Most of the stock is decades old, rent growth tracks wages rather than population, and new Class A supply is concentrated in Bettendorf, which matters most for older complexes on the Iowa side.

Each of the river cities has a different apartment mix and renter base.

Quad Cities By The Numbers

We track 21 Iowa cities. Quad Cities places 17th for median gross rent, 18th for renter share and 11th for five-year rent growth. Its rents sit near the bottom of the group, which keeps it affordable for tenants but also caps what renovations can earn. In raw numbers, Quad Cities has about 328 more residents, 91 more renter households and 2,596 more homes in buildings with 5 or more units than in the 2015–2019 survey. New homes in 5+ unit buildings outpaced the growth in renter households, so newer buildings are competing for tenants and older ones may need to offer more to keep them.

Quad Cities And Nearby Markets Side By Side

Quad Cities's median gross rent of $941 is below the Iowa median of $972, and its renter share is 28.3% compared with 28.3% statewide.

Can Tenants Afford Quad Cities Rents?

The median rent in Quad Cities works out to $11,292 a year, about 15.5% of the median household income of $72,738. Under the common 30% guideline, a household needs about $37,600 a year to cover that rent comfortably. That's close to the Iowa figure of 15.5%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

Since the 2015–2019 survey, the median rent rose $176 a month ($2,112 a year), while median household income rose $14,220 a year. The two have moved together, so affordability today looks much like it did five years ago. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $1,056, is 12.2% 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 A Quad Cities Apartment Building

Our buy box in Quad Cities is the same one we use nationwide: 5+ unit apartment buildings, stabilized or in need of work, priced on today's rents. Then we test the property against the local data on this page and a full inspection of its major systems.

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

We use modest rent growth assumptions, realistic repair budgets and financing that can carry the property through a slower year.

Due Diligence For Apartment Syndications In Quad Cities

Before you invest in an apartment syndication in Quad Cities, with us or anyone else, the local data points to a few questions worth asking.

• What vacancy does the plan assume? Rental vacancy in Quad Cities is 5.9%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 23% 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 Quad Cities was built in 1967, so roofs, plumbing and electrical systems deserve their own line items.
• How will the building compete with new supply? Homes in 5+ unit buildings in Quad Cities rose 11% over five years, so newer properties are part of the competition.
• 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.
