House hacking after 2024: is the math still working?
With FHA at 3.5% down and rates at 6.75%, the classic house hack still pencils — but you need to be more selective about market and unit count than 2020 buyers did.
The classic house hack: buy a 2–4 unit property with owner-occupied financing (FHA at 3.5% down, VA at 0% for eligible veterans), live in one unit, rent the others. The rents from the other units cover most or all of the mortgage. After a year, move to your next house hack and convert the first to pure investment. Done several times in your twenties and thirties, this builds a substantial rental portfolio with minimal capital.
The 2020–2022 environment was unusually favorable: 3% rates, rising rents, and (in many markets) modestly priced 2–4 unit properties relative to single-family homes. Almost any deal penciled. The 2026 environment is harder. Rates around 6.75% on FHA mean monthly P&I on a $500K loan is ~$3,250 — vs. ~$2,100 at 3%. Sun Belt rents have softened. The math is tighter.
Where it still works: stable Midwest and Northeast markets with reasonable price-to-rent ratios (Indianapolis, Kansas City, Pittsburgh, Cincinnati, the smaller Massachusetts and New Jersey markets). Look for: 2–4 units (qualifies for residential financing); the unit you'll live in should be the largest/best; rents in the other units should cover 70–100% of the full mortgage; the building should be in a market where you actually want to live for at least 12 months.
Where it doesn't work: expensive coastal markets where the price-to-rent ratio exceeds 25 (LA, SF, Seattle, much of Northeast). The math rarely clears for new buyers. Also avoid markets where the 2021–2023 multifamily oversupply is still digesting (Austin, Phoenix, Nashville) — even house-hack units face vacancy pressure in those metros.
The hidden upside that rarely makes the spreadsheet: appreciation. The house-hack property bought at age 28 and held through age 50 is typically worth 3–5× the purchase price by then, with a paid-off mortgage. Even if year-1 cash flow is marginal, the long-term wealth effect of the FHA leverage compounding on the down payment is substantial.
