We inherited $250,000. I want a second home, but my wife wants to save for our kids’ college. What should we do?

A $250,000 inheritance creates a marital standoff: one spouse wants a vacation property, the other wants to fund the kids’ college. This tension played out on Reddit’s r/personalfinance, where commenters split between “real estate builds wealth” and “college debt is a life sentence.” Both instincts are understandable. But when you run the numbers, one path is significantly stronger for most families.

Two Spouses, One Inheritance, Two Very Different Plans

• Windfall: $250,000 inherited lump sum
• Option A: Down payment on a second home or vacation property
• Option B: Fund 529 college savings accounts for the kids
• Core tension: Discretionary lifestyle asset vs. tax-advantaged education investment
• What’s at stake: Carrying costs, opportunity cost, future debt load for children

What a Second Home Actually Costs You Right Now

The 30-year fixed mortgage rate on a primary home averaged 6.95% for the week ending September 17, 2026, according to Freddie Mac, marking a roughly 20-month high and the fourth consecutive weekly increase. The 15-year fixed averaged 6.26% in the same survey. Second-home mortgages carry a meaningful premium on top of those figures, with lender data putting average second-home rates well above the primary benchmark for borrowers with strong credit. The Fed Funds target range now stands at 3.75% to 4.00% after the FOMC voted 12-0 to raise rates by a quarter point at its September 16 meeting, citing inflation that remains above the committee’s 2% goal. Markets currently price in at least one additional hike before year-end, which means the mortgage rate environment has no clear relief valve in the near term. The 10-year Treasury yield has risen roughly a full percentage point since its February low, putting further upward pressure on long-term borrowing costs.

A $250,000 down payment on a vacation property sounds substantial, but context matters. Second homes typically require at least 10% down, so the inheritance could theoretically support a purchase in the $500,000 to $800,000 range. That still leaves a large mortgage layered on top of a primary residence, plus recurring property taxes, insurance, maintenance, and HOA fees. Carrying two mortgages on one household income is a genuine cash flow risk, not a minor inconvenience to plan around. With rates at a 20-month high and trending upward, the monthly payment on any new second-home loan is meaningfully higher than it would have been a year ago.

Consumer sentiment has deteriorated sharply alongside the rate environment. The University of Michigan’s preliminary September 2026 reading came in at 47.8, down 7.5% from August’s final reading of 51.7 and now sitting below the first percentile of the index’s entire history. Sentiment is 13% below year-ago levels, and year-ahead inflation expectations jumped to 4.6% in September, the highest since June. That combination of fragile confidence and rising price expectations is a poor backdrop for taking on new discretionary debt, regardless of where the headline index lands in any given month.

The College Math Is More Urgent Than Most Parents Realize

Four-year public in-state tuition and fees average $11,950 for the 2025-26 school year, according to the College Board. The full cost of attendance for an in-state student at a public four-year university, including room and board, books, and personal expenses, averages $30,990 per year. For two children completing four-year degrees, the total bill in today’s dollars approaches $250,000, and every year you delay saving, that gap widens.

Education costs have consistently outpaced general inflation. Private nonprofit four-year tuition increased 4% before inflation adjustment in 2025-26, while room and board at public four-year schools averaged $13,900. Every year a 529 sits unfunded, the compounding advantage shrinks and the gap between savings and tuition widens further, making early action far more valuable than a larger contribution made later.

The tax case for 529 accounts is clear. Contributions grow tax-free, and withdrawals for qualified education expenses are federally tax-free. In 2026, a married couple can contribute up to $38,000 per child per year without triggering a gift tax filing. The “superfunding” election lets you front-load five years of contributions at once, so a couple could deposit up to $190,000 per child in a single year. With two children, a $250,000 inheritance could be nearly fully deployed into 529 accounts, giving years of tax-free compounding an immediate head start.

The accounts are also more flexible than they used to be. Under the One Big Beautiful Bill Act, signed July 4, 2025, the annual K-12 withdrawal limit doubled to $20,000 per beneficiary beginning in tax year 2026, and qualified expenses now include curriculum materials, tutoring, and standardized test fees. That expansion broadens the range of uses well beyond college tuition, making 529s useful even if a child takes a non-traditional academic path.

The Honest Tradeoff Between These Two Paths

A second home can appreciate over time and generate rental income, but it concentrates wealth in an illiquid, high-maintenance asset at precisely the moment when borrowing costs are at a multi-year high. The national personal savings rate was 3.0% in July 2026, according to the Bureau of Economic Analysis, ticking up from June’s 2.6% but still well below the levels typical of prior economic expansions. Household budgets remain under pressure from elevated inflation, and adding a second mortgage onto that backdrop raises financial fragility without the safety net of a liquid reserve.

A 529, by contrast, is tax-efficient, directly addresses a known future liability, and retains more flexibility than most parents realize. Unused funds can now be rolled into a Roth IRA for the beneficiary under the SECURE 2.0 provisions, eliminating the longstanding concern that over-funding traps capital forever.

The 529-to-Roth IRA Pipeline: Overcoming the Overfunding Fear

The most common psychological barrier to choosing college savings over real estate is fear of locking up capital permanently. Under SECURE 2.0, a beneficiary can roll over up to a lifetime maximum of $35,000 from an unused 529 plan directly into a Roth IRA. The rule requires the account to have been open for at least 15 years, and rollovers count against the beneficiary’s annual Roth contribution limit for that year. The result is a tax-free wealth transfer mechanism that converts idle education savings into retirement capital, a two-for-one outcome a vacation home simply cannot match.

A second home becomes a reasonable goal once rates fall and household income has grown. Using a one-time windfall to take on ongoing leverage in a rising-rate environment, while leaving a known six-figure education expense unfunded, puts the steps in the wrong order.

The Middle Way: A Staged Windfall Strategy

If a couple remains fundamentally deadlocked, a partial superfunding approach offers a middle path that honors both goals without high-leverage debt. Families can immediately place a portion of the windfall, such as $75,000 per child, into 529 plans to lock in tax-free compounding against rising education costs. The remaining cash can be parked in short-term Treasury bills or a high-yield savings account, preserving liquidity and creating a down payment fund deployable for a vacation home in three to five years, once the rate environment improves and household income has grown to support the carrying costs comfortably.

How to Deploy the $250,000 Without Regret

1. Prioritize the 529 accounts first. Use the superfunding election to deposit a lump sum for each child. Splitting $190,000 to $200,000 between two accounts locks in years of tax-free growth immediately. The remaining $50,000 to $60,000 stays liquid or goes to your emergency fund.
2. Revisit the second home in three to five years. If rates fall and your income has grown, a vacation property financed on your own cash flow makes far more sense. Buying a discretionary asset with earned income is structurally sounder than buying it with a one-time inheritance.
3. Avoid splitting the money equally between both goals. Dividing $125,000 each way leaves the college accounts underfunded and the down payment too small to avoid carrying costs that strain your monthly budget.

Editor’s note: This pass updates the primary mortgage rate to 6.95% per Freddie Mac’s September 17, 2026 survey (a roughly 20-month high), replaces the forward-looking FOMC language with the confirmed September 16, 2026 outcome (a unanimous 12-0 vote to raise rates to 3.75%-4.00%), refreshes consumer sentiment to the preliminary September 2026 reading of 47.8 (below the first percentile historically, with year-ahead inflation expectations rising to 4.6%), and updates the personal savings rate to 3.0% in July 2026 per the BEA’s August 26 release.
