Fannie Mae Report: Workforce Housing

October 5, 2026

This post summarizes Fannie Mae’s findings on the workforce housing market, defined by the Urban Land Institute as households earning sixty to one hundred percent of Area Median Income. This group represents roughly thirty percent of all renter households in the United States, yet very few new units are being built to serve them. Most new construction targets renters earning above one hundred percent of AMI or below sixty percent of AMI, leaving a significant gap for the middle income households who form the backbone of local economies.

This HT Extra takes a closer look at the rental housing marketplace, examining how demand, supply constraints, pricing pressures, and shifting renter demographics shape today’s rental landscape. It offers a concise breakdown of the forces influencing rents and highlights the importance of expanding attainable housing options for working households.

Ending the Stigma of Trade School

This article calls for ending the long standing stigma around vocational and trade schools. It emphasizes that parents often unintentionally reinforce outdated beliefs about four year degrees being the only respectable path, even though skilled trades offer strong career opportunities, financial stability, and essential contributions to the economy. The piece encourages families to recognize the value of trade education and support students who choose hands on, career focused training.

HousingThink Podcast – Episode 3

Where are the Republican YIMBYs?

This post raises a long standing question about why so few Republicans publicly embrace YIMBY principles, despite the party’s traditional support for market driven solutions and regulatory reform. The referenced discussion with Nolan Gray of the Mercatus Center explores how pro growth housing policies could align with conservative priorities, and why that alignment has not yet translated into a larger Republican YIMBY presence.

Thom Amdur, Executive Director and President of the National Housing and Rehabilitation Association, joins Jeff Carroll and Doug Koch to explore how off site construction and greater construction flexibility can reshape the future of affordable multifamily housing. The conversation highlights emerging building strategies, evolving industry standards, and the opportunities developers have to deliver high quality housing more efficiently.

Let’s Say ‘Yes In My Backyard’ To Fix Housing Woes

This article argues that rising housing costs, homelessness, and environmental pressures demand a shift away from exclusionary NIMBY attitudes. Instead, it calls for a YIMBY approach that embraces dense, responsible development. By supporting more housing in more places, communities can expand supply, reduce displacement, and create healthier, more sustainable urban environments.

HousingThink Podcast – Episode 5

This episode introduces listeners to the core idea of workforce housing, a market segment made up of people who earn too much to qualify for traditional affordable housing yet not enough to comfortably rent newer market rate apartments. The show puts a face on this often overlooked group, highlighting the essential workers who keep communities running while struggling to find stable, attainable homes.

We Need More Housing, Not More Rent Control

This article argues that rent control does not address the root causes of rising housing costs. When legislation restricts housing supply, prices climb regardless of caps. The piece emphasizes that simply “letting the market handle it” is not enough, because many government interventions already limit the ability of builders to deliver affordable homes. Zoning rules and other land use regulations are identified as major drivers of high housing prices. The article concludes that meaningful affordability requires land use liberalization and the repeal of restrictive measures that prevent new housing from being built.

HousingThink Extra – Episode 5

This HT Extra introduces listeners to members of the nation’s workforce, the people whose daily labor keeps the economy moving. The episode highlights the essential roles these workers play and sets the stage for deeper conversations about the housing challenges they face across different industries and regions.

Why Is The Thermal Envelope So Important?

This article explains why the thermal envelope is one of the most important elements in home construction. While homeowners often focus on style, layout, and finishes, the thermal envelope determines how efficiently a house uses energy and water. A strong envelope helps the home function as a complete system, reducing waste, lowering utility costs, improving comfort, and minimizing reliance on toxic or inefficient materials. It is both an environmental priority and a long term financial advantage for homeowners.

Prohibiting Underground Parking Creates Obstacles for Affordable Housing

This article outlines how proposed rules from the District’s Department of Energy and Environment would restrict underground parking for purely residential buildings unless developers secure a code modification. Mixed use projects, however, would retain the ability to build underground parking by right. These changes add another barrier to delivering affordable housing, increasing costs and limiting design flexibility for projects that rely on efficient parking solutions to remain financially feasible.

HousingThink Podcast – Episode 6

This episode explores how veterans fit into the workforce housing market and why so many workforce housing renters end up in lower quality homes. The discussion highlights the unique financial and logistical challenges veterans face when searching for stable, affordable housing, as well as the broader market pressures that push many renters into older, less desirable units. It underscores the need for more purpose built workforce housing that supports veterans and other essential workers.

How Developers are Helping Teachers Find Affordable Housing

Teacher salaries have fallen behind housing costs in many metro areas. Adjusted for inflation, teacher pay has dropped four point five percent since the 2009–10 school year, while national home prices have climbed more than forty three percent. This widening gap has pushed many educators out of the communities they serve or out of the profession entirely. The article highlights how developers and school districts are partnering to create dedicated housing solutions for teachers, offering stable, affordable homes that help retain talent and strengthen local schools.

HousingThink Podcast – Episode 7

This episode focuses on the housing challenges teachers face when trying to live near the schools where they work. Rising rents, limited supply, and long commutes make it difficult for educators to find stable, affordable homes within their districts. The conversation also explores strategies for partnering with local municipalities to create new housing options tailored to this essential workforce, highlighting how collaboration and thoughtful planning can support teachers and strengthen communities.

Why Affordable Housing Is So Hard to Find in America’s Big Cities

This article explains how increased land use and zoning regulation has driven housing prices higher across most states. Vanessa Brown Calder’s research for the Cato Institute shows that states with the largest growth in rules and restrictions also experience the steepest increases in real home prices. The piece notes that federal housing funds often flow to states with more restrictive zoning, unintentionally discouraging local reforms that would expand supply. The result is a system where regulation raises costs, limits new development, and makes affordable housing harder to find in major cities.

HousingThink Podcast – Episode 8

This episode looks at the housing challenges firefighters face, including long commutes, limited availability near stations, and rising rents that outpace wages. The conversation also revisits the debate around rent control, emphasizing why price caps often fail to improve long term affordability. Instead of expanding supply, rent control can reduce it, pushing essential workers like firefighters farther from the communities they serve.

The YIMBY Act Passes House by Voice Vote

This update highlights the bipartisan momentum behind the YIMBY Act, legislation aimed at encouraging cities to modernize outdated zoning codes that restrict housing supply. By tying Community Development Block Grant Consolidated Plans to pro‑housing reforms, the bill pushes local governments to adopt practices that support more flexible land use and reduce barriers to new development. With versions introduced in both the House and Senate, the YIMBY Act reflects growing national recognition that regulatory modernization is essential for expanding housing opportunities and strengthening local planning efforts.

HousingThink Podcast – Episode 9

This episode examines why police officers often end up living in older housing and, in many cases, face long daily commutes. Limited affordability, rising rents, and the mismatch between wages and modern apartment prices push many essential workers farther from their jobs. The conversation also highlights the growing momentum of the YIMBY movement, which advocates for more housing supply and more flexible development policies to help reduce these pressures.
