The “choice” in the Housing Choice Voucher (HCV) program signals the mobility offered to voucher holders. However, some landlords use source of income (SOI) discrimination to exclude voucher holders—limiting their locational choices. We propose several factors likely to influence this landlord strategy including, market competitiveness, stereotypes, and racial discrimination. We examine the prevalence of express SOI discrimination and the effectiveness of SOI antidiscrimination laws. We utilize a novel dataset of 1,107,110 rental listings from the Craigslist pages of 77 mid-sized US cities. We find significant amounts of express SOI discrimination, even where there are SOI antidiscrimination laws. Using multilevel models, we find that landlords are more likely to expressly discriminate in lower-opportunity neighborhoods and when they own market-competitive units. We also find that these factors are moderated by the concentration of voucher holders. These findings underscore how landlord strategies can combine to undermine the choice afforded to voucher holders.

住房选择券 (HCV) 计划中的“选择”标志着向券持有者提供的流动性。然而，一些房东使用收入来源 (SOI) 歧视来排除代金券持有者，从而限制了他们的选址选择。我们提出了几个可能影响这种房东策略的因素，包括市场竞争力、刻板印象和种族歧视。我们研究了明确的 SOI 歧视的普遍性和 SOI 反歧视法的有效性。我们利用来自美国 77 个中型城市的 Craigslist 页面的 1,107,110 个租赁列表的新颖数据集。我们发现大量明确的 SOI 歧视，即使有 SOI 反歧视法。使用多级模型，我们发现，在机会较少的社区以及拥有具有市场竞争力的单位时，房东更有可能明确歧视。我们还发现，这些因素受到代金券持有者集中度的影响。这些发现强调了房东策略如何结合起来破坏优惠券持有人的选择。
