IRS SOI migration for 2022–2023 recorded 3,626 tax-return households moving from Chicago to Phoenix, associated with 5,740 exemptions as a people proxy. The corridor represented 3.14% of Chicago’s outbound returns and 3.85% of Phoenix’s inbound returns. Across all tax-return routes in the same release, Chicago had a net loss of 22,024 returns, while Phoenix had a net gain of 12,377. These figures measure tax-return households—not renters, every mover or future demand—so they establish a defined migration corridor rather than a rental-demand forecast.
On Zillow’s 2026-06-30 metro measures, the immediate household trade-off is lower asking rent but a higher home-value benchmark. Typical asking rent changes from $2,275 in Chicago to $1,733 in Phoenix, while typical home value changes from $359,888 to $447,054. The corresponding gross-yield screen is 7.59% in Chicago and 4.65% in Phoenix. For a renter, the destination therefore presents a lower market-rent reference. For a buyer or rental-property underwriter, it presents a higher acquisition basis with less market asking rent relative to value before any expenses.
That split is the corridor’s central distinction. Moving to Phoenix can reduce the advertised monthly rent benchmark without making housing uniformly cheaper: HUD’s rent standard and BEA’s housing-cost index provide counterevidence, while Phoenix household income is lower on a separate Census release. Rental-property underwriting also changes from a higher-yield Chicago screen to a Phoenix case that depends more heavily on unit-level rent, expense and purchase assumptions. The next question is whether achievable rent, vacancy, taxes, insurance, maintenance, association charges and financing can support net operating income at the actual Phoenix acquisition basis.
