House Hacking Returns in 2026 Despite Rate Environment

First-time buyers are increasingly using house-hacking strategies, or purchasing two-to-four unit properties and renting out spare units, to offset elevated mortgage rates. Among FHA borrowers under age 35, 18% purchased a two-to-four unit property in fiscal year 2025, up from 11% in 2022, according to HUD loan-level data analyzed by the Urban Institute.

The approach allows buyers to qualify for the same owner-occupant FHA terms, including 3.5% down payment, that they would receive on a single-family home, while generating rental income to offset part of the mortgage. FHA guidelines also allow up to 75% of prospective rental income from the additional units to be counted toward borrower qualification.

"House hacking used to be a niche strategy discussed mostly on investor forums, and it has become mainstream," said Laurie Goodman, institute fellow at the Urban Institute. Goodman said the shift reflects affordability pressure that is pushing first-time buyers to seek creative paths to ownership in competitive metros.

Property types vary by region. In the Northeast, triple-deckers and stacked two-family homes remain common in Boston, Philadelphia, and Providence. In the Midwest, two-flats proliferate in Chicago, Minneapolis, and Milwaukee. In the South, purpose-built duplexes in Atlanta, Nashville, and Charlotte account for much of the two-to-four unit transaction activity.

BiggerPockets, the investor-focused platform, reported that searches for "house hacking" on its site rose 68% in 2025, and associated forum post volume hit a record. Scott Trench, CEO of the platform, said median age of members completing a first deal using house-hacking principles fell from 31 to 28 over the past three years.

Fannie Mae has responded with product adjustments. In October 2024 the agency lowered the down payment requirement on conventional two-to-four unit owner-occupied purchases from 15% to 5%. That brought conventional financing closer to FHA for house-hackers who exceed FHA loan limits.

Not all stories work out. A Consumer Financial Protection Bureau research note published in February flagged delinquency risk among first-time buyers who purchased two-to-four unit properties assuming quickly-realized rental income. Delinquency rates on FHA 2-4 unit loans originated in 2023 were 1.8 percentage points higher than single-family FHA from the same year, controlling for credit score and debt-to-income ratios.

"The strategy works, but it requires more diligence than a typical first purchase," said Ben Leybovich, a real estate investor and educator. Leybovich recommends potential house-hackers verify existing rents with current leases and pay for professional inspections of each unit. The upfront complexity, he said, is what separates successful outcomes from underwater ones.
