- Abstract
U.S. rental affordability deteriorated sharply after 2019 and partially reversed in some markets after 2022. The Sun Belt rent decline is well documented in industry data; what has not been measured is how much rent versus income each contributes to the metro-level burden change. We apply a log-additive decomposition, Δlog(burden) ≡ Δlog(rent) − Δlog(income), to a balanced panel of 14 U.S. metropolitan areas observed annually from 2019 through 2025, with bootstrap, jackknife, and permutation inference. Over the full 2019–2024 window the income side accounts for most of the change in every supply group. In the 2022–2024 post-surge window the rent-side contribution flips sign: positive in supply-constrained coastal metros (+0.036, 95% CI [+0.021, +0.052]) and negative in high-supply Sun Belt metros (−0.025, [−0.046, −0.011]; permutation p = 0.005). Even within the Sun Belt the income side is roughly four times larger in magnitude than the rent side (−0.096 vs. −0.025), so rent moderation distinguishes regimes but is not the larger force in either. The reversal appears in CoStar asking rent but not yet in ACS gross rent; cross-correlation places the peak transmission lag at one year (Pearson r = 0.76, p < .001).
