Background
The Build-to-Rent (BTR) sector faces a critical data challenge. Despite surging growth and investment, the industry relies on lagged, fragmented, and opaque information. This gap leads to significant capital deployment with limited market visibility. Case in point: Austin's 2024 market, where flawed assumptions have left builders, investors, and operators vulnerable.
Parcl Labs addresses this challenge through a Big Data and data science-driven approach. By synthesizing over 5,000 sources, we track BTR units in real-time. Our definition—newly constructed single-family homes observable as rentals shortly after completion—provides insights into actual BTR supply based on real-world activity.
This report analyzes U.S. national trends and seven key institutional markets (Atlanta, Austin, Charlotte, Dallas, Houston, Phoenix, Tampa), offering market metrics, SFR unit mapping, and granular data snapshots. Our unique perspective equips investors and operators with timely, accurate information to navigate this maturing sector effectively.
This analysis is part of our ongoing BTR series. If you're interested in accessing the full report, which includes additional metrics and deeper insights, please email team@parcllabs.com.

Appendix - Methodology
BUILD TO RENT INDEXING METHODOLOGY
Our build-to-rent methodology relies on observable events occurring within the housing market. We look for new construction units that are rented within 6 months of being built, starting in the year 2020. A unit can fall out of measurement if it's sold to a new owner and doesn't reappear on the rental market within 6 months of the subsequent sale.There is much confusion around the definition of build to rent. Many methods rely on surveys, which covers a small subset of the overall housing market, are prone to biases, and don't have a clean reconciliation method. The issue with build to rent is that they are not static. Unlike commercial multifamily which can only serve one purpose, these are residential units that can be rented or sold. This requires better, more complete data to ensure an accurate pulse on what's occurring within the housing market.
RENTAL INDEXING METHODOLOGY
Our methodology for all rental units combines both on market and observed portfolio behaviors. When a unit is purchased by a portfolio consisting of rentals, we annotate this unit as being used as a rental unit. For example, say we have a mom and pop operator in Austin, Texas who owns 8 units. We have observed these units participate in the rental market. This operator buys a 9th unit. We will immediately annotate this 9th unit as a rental given the characteristics of the overall portfolio. This allows us to accommodate for situations where mom and pops fill units via personal relationships, never observing the rental on market.
VACANCY METHODOLOGY
Given the previously referenced indexing methods for both build to rent and total rental units, vacancy rate calculations are simply the number of units observed on the rental market divided by the total number of units annotated as rental units or build to rent units. Market vacancy rate includes both BTR and scattered site units.RENTAL PRICE PER SQUARE FOOTRental price per square foot is calculated by taking the interior square footage of a unit divided by the asking rental price by rental type.
MARKET DEFINITION METHODOLOGY
Except for the United States, which covers all 50 states, markets are referring to the metropolitan statistical areas (MSA). We use Census defined MSA geometry boundary files. If a unit's geocoding information falls within this boundary, we include it in that market. Our unit data includes latitude and longitude geocoding information to give flexibility in defining different market criteria for various metrics.
FINAL REMARKSThe included metrics in this report are a snapshot of what's possible quickly with our unit level data, however they are one perspective. You may have many other perspectives on how to articulate insights regarding the housing market.We spent years developing a multi-source, geospatial indexing technology to create a unified view of every residential unit in the country, tying together disparate rental, listing and sales data into one clean, timestamped and chronologically ordered sequence of events occurring around that unit. Today, we accumulate data from over 5,000 sources and the rate of source data integration is accelerating. Given the recent volatility in housing market litigation, housing data will likely become more fragmented. It's imperative to have better information to make more intelligent decisions.
