See it on the Money & Finance map →How it works
About 590,000 apartments were completed in 2024, the most since 1974, mostly in Sun Belt cities. Vacancy rose and rents stalled; CoStar put national vacancy near 8.2% in Q2 2026, from about 5% in the Northeast to 11% in the South. Leases are short, usually a year, so income resets quickly with the market. Multifamily mortgage debt was about $2.29 trillion at end-2025 (MBA): about half held or guaranteed by Fannie Mae, Freddie Mac and other agencies, 29% by banks.
Why it matters
People always need housing, so lenders, including the government-backed agencies, keep financing apartments in downturns, making them the most liquid commercial property type.
Facts, rules and data
Census completions data, RealPage and CoStar vacancy surveys, MBA quarterly mortgage-debt reports, and Fannie Mae and Freddie Mac filings.
Debates and risks
How fast rents recover as new supply drops after 2025, and how rent-control laws, including California's statewide cap, affect values, are debated.
Connections (3)
▸Apartment (multifamily) real estate is financed largely by Agency apartment loans: Fannie Mae DUS and Freddie Mac OptigoFact, law or data
The connection
Fannie Mae and Freddie Mac buy or guarantee apartment loans made by approved lenders, then sell them as bonds carrying their guarantee. Because investors trust that guarantee, apartment owners get lower rates, up to about 80% leverage and non-recourse terms. With other agencies, they held or backed about half of the $2.29 trillion in multifamily mortgage debt at end-2025.
When and why
Nationwide; Fannie's DUS program since 1988, Freddie's K-Deals since 2009, under FHFA lending caps of $88 billion each for 2026.
How we know
MBA quarterly mortgage-debt data, FHFA annual caps, and Fannie Mae and Freddie Mac 10-K filings.
Debates and risks
How agency support would change if Fannie and Freddie leave conservatorship, and whether it crowds out private lenders, is debated.
▸Apartment (multifamily) real estate gains renters priced out of the Home prices and the housing marketMainstream view
The connection
When home prices and mortgage rates are high, fewer renters can buy. As 30-year mortgage rates rose from about 3% to 7% in 2022, a typical home payment rose far above typical rent. Would-be buyers stayed in apartments longer, supporting occupancy even as record new supply arrived.
When and why
US-wide, 2022–26; the median first-time buyer's age reached a record 40 in 2025 (National Association of Realtors).
How solid is the link?
NAR and Census homeownership data, Freddie Mac mortgage-rate surveys, and rent-versus-buy cost studies.
Debates and risks
Whether falling mortgage rates would pull renters into homes and soften apartment demand, and how quickly, is debated.
▸Apartment (multifamily) real estate suffered floating-rate defaults on Bridge loans: short-term, floating-rate transition financingFact, law or data
The connection
In 2021–22 many buyers, often syndicators raising money from individual investors, bought Sun Belt apartments at high prices with floating-rate bridge loans. When SOFR rose from near zero to over 5%, interest costs more than doubled, rate caps expired and values fell. Many could not refinance, leading to defaults, capital calls and foreclosures.
When and why
Mainly Texas, Arizona, Florida and Georgia, 2023–26, in loans held by debt funds, mortgage REITs and CRE CLOs.
How we know
CRE CLO delinquency reports from Trepp and CRED iQ, mortgage REIT filings, and lawsuits and foreclosures involving syndicators.
Debates and risks
How many troubled loans were quietly modified rather than foreclosed, and how large final losses will be, remains unclear.
