Getting Started

Ways you can leverage endpoints today:

Get real-time housing market prices through the Price Feed endpoint.
Access real-time rental market prices through the Rental Price Feed endpoint.
Use the Volatility endpoint to analyze market risk. The Volatility metric, updated daily, assesses the degree of variation from the average return by determining daily returns from the PLPF, applying a rolling standard deviation tailored to market specifics, and annualizing the measure.

How the Parcl Labs Price Feed Works

The PLPF tracks daily price changes in residential real estate across various markets and property types, using price per square foot as a simple metric. Parcl Labs offers real-time home price and rental price feeds.

To generate the PLPF, we use a comprehensive ETL process to handle, clean, and refine large datasets, applying spatial data science to produce precise price estimates for market areas. Our methodology looks at representative segments of the market, filters outliers and other irregularities, creates smooth time series, and is tested on a daily basis to guarantee the quality of our indicator.
