a person who rents out houses and flats that are in poor areas and in poor condition, often charging unfairly high rents

The mayor said he was pleased with the progress the District has made in compelling slumlords to improve substandard living conditions. 市长表示，他对该区在迫使贫民窟房东改善不合标准的生活条件方面取得的进展感到高兴。

The goal is to find a way to protect tenants from slumlords, and property managers from bad tenants. 目标是找到一种方法，既能保护租户不受贫民窟房东的侵害，同时保护物业经理不受不良租户的影响。
