The measured IRS flow from Dallas to Austin was 6,408 tax-return households, associated with 9,291 exemptions as a people proxy, in the 2022–2023 period. Average AGI was $95,398.1 per return. This is evidence of an established filer corridor, but the population boundary matters: IRS flow means tax-return households. It does not identify renters, every mover or future housing demand, so it should open the comparison rather than stand in for a leasing forecast.
At the June 30, 2026 Zillow observation, Austin’s asking rent was $1,653 versus $1,673 in Dallas, a destination difference of $20 per month and $240 annually. The home-value comparison moves the other way: Austin was $426,944 versus $366,701 in Dallas, a $60,243 destination gap. A renter therefore encounters a slightly lower metro asking-rent benchmark, while a household considering ownership—and an investor evaluating acquisition basis—faces a higher home-value reference.
For rental-property underwriting, Austin’s gross yield was 4.65% versus 5.48% in Dallas. That is a lower initial income screen despite the slightly cheaper monthly rent; gross yield is not an operating return and does not include property-specific expenses or financing. The next underwriting question is whether achievable unit-level rent, after concessions and vacancy, covers the actual acquisition basis plus taxes, insurance, repairs, management, association charges and any flood-mitigation needs. The corridor data cannot answer that without a specific property and submarket.
