The economic stake sits in one paradox. The Low-Income Housing Tax Credit, born from the Tax Reform Act of 1986, provides up to $15 billion a year in subsidies and underwrites nine of each 10 subsidized units built nationwide; HUD describes it as “the most important resource for creating affordable housing in the United States today”. Yet in Portland, Oregon, nearly 2,000 subsidized apartments sit vacant, while the National Low Income Housing Coalition’s 2026 Gap report counts 11 million extremely low-income renter households competing for 3.8 million homes they can afford, a national shortage of 7.2 million. For every 100 of those households, data shows, 35 homes exist.
The mechanism explains the mismatch. Credit rents are tied to area median income bands, commonly 50% or 60% of AMI, not recalculated so each tenant pays 30% of their own income. According to an Associated Press investigation, extremely low-income households, the group at or below federal poverty income or 30% of AMI, got only about 12% of credit-financed units in 2024. In Portland, meeting the standard only needed rents a household at 60% of median income could pay, about $75,000 a year for a family of four. The resulting one-bedroom price, on the order of $1,400 a month, is manageable at that income and nearly half the monthly pay of someone earning $35,000 at the local minimum wage.
City numbers sharpen the point. Austin, Texas, counted more than 4,500 vacant affordable apartments, a vacancy rate near 16%, and had completed just 543 homes against a 2018-2027 goal of 20,000 for extremely low-income households, while finishing all 15,000 units targeted at the 60% to 80% band. Denver’s vacancy rate was reported at 13% for units serving 60% of AMI and 21% at 80%. The gap is arithmetic, not appetite: one developer’s unit at 60% of AMI collected $1,715 in monthly rent against roughly $1,575 in mortgage and operating costs. Cut the rent toward 30% of AMI and the building develops a funding gap; Austin’s documents show deeply affordable projects drawing city gap financing above $68 million. “It costs too much to build housing to turn around and rent it to households who are low-income households,” said Jennifer Schwartz of the National Council of State Housing Agencies,
The critics go further. “The evidence is telling us this program is lacking its reason to exist,” said Kirk McClure, an emeritus urban planning professor at the University of Kansas, urging that “We should reform the program to make it work better.” A dozen studies spanning 1991 to 2024 concluded that rental vouchers would serve many more people, with estimates running to twice the impact per dollar. The industry answers with production: “The program leverages housing market forces, entrepreneurial innovation and private accountability to increase housing supply,” former HUD Secretary Ben Carson told a House committee in 2025. Senator Ron Wyden of Oregon defended it in writing: “There isn’t any silver bullet to the housing crisis in Oregon and around the country,” his statement said, “but the low-income housing tax credit has been the most successful federal housing construction program on the books for decades and is the only housing program Republicans haven’t tried to gut.” Congress, in last year’s spending package, approved the program’s biggest expansion in decades, and FHFA doubled the Fannie Mae and Freddie Mac investment limits to $2 billion each in August 2025.
On the ground in Portland, the market has closed the distance. Market vacancy ran about 7.6% in May against 11% for subsidized units, in an industry that treats 5% as normal turnover; the city caps a one-bedroom at 60% of median income at $1,444 while the market average is near $1,581, and in Gresham a credit-built two-bedroom is capped at $1,675 against a $1,525 Zillow equivalent. Operators of a $53.8 million development began offering a month of free rent. “The idea that we’re competing with the market would have been unfathomable a few years ago,” said Margaret Salazar, head of REACH Community Development, one of the city’s largest affordable providers; Her organization can now serve only a slimmer slice of residents. More than 90,000 Multnomah County households earn less than what a subsidized unit typically requires, 60% of median income, and vouchers reach only 1 in 4 who qualify.
The bottom line is a naming problem with a budget attached. One label, affordable housing, covers units for families at 80% of median income and for families at 30%, and only the second group faces the 7.2 million-home shortage. Until the scorecard asks who can actually afford the units, not how many were built, the vacancy columns and the shortage columns will keep disagreeing.
