IRS SOI measured 1,966 tax-return households moving from Detroit to Chicago in 2022-2023, with AGI of $78,540.18 per return. This establishes a past directional link between the markets, but the population boundary matters: IRS flow means tax-return households. It does not identify renters, every mover or future demand. The count therefore cannot show how many Chicago apartments were absorbed, whether those filers bought homes or how long they remained in the destination.
The later Zillow snapshot shows the immediate housing-cost reset. Metro asking rent moves from $1,518 in Detroit to $2,275 in Chicago, a difference of $757 per month and $9,084 per year. The home-value measure rises from $271,675 to $359,888, a gap of $88,213. For a household, Chicago’s higher income benchmark must therefore be tested against a materially larger housing bill rather than treated as a clean gain in purchasing power. Actual results will depend on the unit, tenure choice, neighborhood and commute.
For rental underwriting, Chicago combines a higher entry value with more nominal rent relative to value. The market evidence’s gross-yield indicator moves from 6.7% in Detroit to 7.59% in Chicago, but gross yield excludes the expenses that determine cash flow. Climate exposure also warrants a less favorable destination assumption at the market level: the FEMA annual building-loss ratio is 0.0915% for Detroit and 0.1277% for Chicago. The next underwriting question is whether achievable unit rent still supports the required cash-flow margin after property taxes, insurance, owner-paid utilities, maintenance, vacancy, management, capital expenditures and financing.
