霍诺卢鲁的公寓项目在三年内为瓦胡岛创造了500多个新的住房空缺, A Honolulu condo project created over 500 new housing vacancies on Oahu in three years by freeing up older, more affordable homes.

哈瓦伊大学的一项研究发现, 在荷诺卢鲁的一个512套公寓项目在三年内通过房屋选在奥阿胡岛上创造了500多个新的空置住房. 这样居民搬进新单位就能释放出旧的住宅. A University of Hawaii study found that a 512-unit condo project in Honolulu created over 500 new housing vacancies across Oahu within three years through housing filtering, where residents moving into new units freed up older homes. 废弃的房屋通常较大,价格更实惠 (平均每平方英尺减少40%) 而且更多的是三间或以上卧室的单户住宅. The vacated homes were typically larger, more affordable—averaging 40% less per square foot—and more likely to be single-family homes with three or more bedrooms. 市场价格的建筑产生的空缺总数更多,而收入受限制的单位更常释放低成本住房. Market-rate construction generated more total vacancies, while income-restricted units more often released lower-cost housing. 大多数搬迁发生在当地,这表明新的住房供应,包括市场价格单位,可以通过激活旧的住宅库来提高可负担性,限制建筑政策可能会减少整体可用性. Most relocations occurred locally, suggesting new housing supply, including market-rate units, can boost affordability by activating older housing stock, and policies limiting construction may reduce overall availability.
