Generally no — a 529 plan cannot be used tax-free to buy a house or pay down a mortgage as though it were a normal purchase. But 529 funds can, in specific situations, be used for qualified room-and-board costs, which is a very different thing.
You generally cannot use 529 funds tax-free to buy a house or make a mortgage payment as if it were a qualified education expense. Where 529 money can help is with room-and-board costs in certain limited circumstances.
529 withdrawals are tax-free when used for qualified education expenses. Those include tuition, fees, books, supplies, required equipment, and — importantly for housing — room and board for a student enrolled at least half-time.
The key distinction is that 529 funds can cover room-and-board costs, not the purchase of the home or the mortgage itself. When a student lives on campus, it is the school’s room-and-board figure; off campus, there are additional rules.
For off-campus housing, the amount that can be treated as qualified is generally capped by the institution’s published cost-of-attendance allowance for room and board. A family cannot simply treat the entire monthly housing payment as qualified.
The room-and-board treatment applies to a student enrolled at least half-time at an eligible institution. It is not a way to fund housing for someone who is not an eligible student.
Using 529 money for non-qualified expenses — such as buying a house outright or paying a mortgage beyond qualified room-and-board rules — triggers ordinary income tax on the earnings portion plus a penalty.
529 funds are best understood as covering eligible housing costs, not as a down payment or purchase vehicle. If the goal is to buy a home near campus, the financing answer is a mortgage structure — not a 529 plan.
529 plans cover eligible room-and-board — not a home purchase. Confirm the tax rules with a qualified advisor, and treat the purchase as a separate financing question.
