中文导读
理财博主 Ben Felix 从沉没成本（不可收回成本）的硬核角度对比买房与租房，将其提炼为实用的“5% 经验法则”，框架虽基于加拿大，但逻辑全球通用。
为什么 HN 推它
HN 网友公认最干净、最符合逻辑的买房 vs 租房一阶近似决策模型。
「这家伙用一阶近似把买房租房的财务账算得清清楚楚，逻辑无懈可击。」HN 网友原话：This guy breaks down the analysis very cleanly to a first-order approximation, using 2019 figures
英文原摘要（HackerTube / Claude 整理）
Ben Felix explains how to compare renting and buying a home by looking at unrecoverable costs, and distills it into the 5% rule of thumb. It is framed for a Canadian audience but broadly applicable.
HN points to it for a clean first-order framework for the rent versus buy decision.
