The Real Estate Rent-Sale Ratio Calculator is a Chrome add-on by liambishop1024. This tool is designed to calculate the rent-sale ratio of a specific neighborhood on the Lianjia website. It provides essential metrics such as the house payback period based on rent, rent-sale ratio, and rental yield percentage.

With this calculator, users can determine the house payback period by dividing the house price by the monthly rent. It helps in assessing the property bubble based on the payback period. Additionally, it calculates the rent-sale ratio (rent divided by house price) and the rental yield percentage (monthly rent multiplied by 12 divided by house price multiplied by 100%). A normal rent-sale ratio typically falls between.
