Everyone Wants to Retire Near the Grandkids. Almost Nobody Runs the Math

This is one of the most common retirement questions we get, and it almost never comes with a spreadsheet attached. Someone in their late fifties or early sixties calls to say the first grandchild just arrived, and suddenly the retirement plan pointed at the Carolinas or Arizona is being redrawn around a zip code they never researched. The emotional logic is unimpeachable. The financial logic is where it gets complicated, because “near the grandkids” is a location constraint that quietly rewrites almost every other line in the budget. Let’s actually run it.

The Hidden Cost of Being a Price Taker

When you pick a retirement town for weather or taxes, you shop the whole country. When you pick it for proximity, you inherit your adult child’s housing market, state income tax regime, and property tax structure whether they suit your retirement or not. That is the entire game, and it is why the math looks so different from a generic 4% article.

The backdrop is not friendly right now. The S&P Cotality Case-Shiller U.S. National Home Price Index stood at 335.10 as of May 2026, its highest reading in the trailing 12 months. Since then, the picture has grown more nuanced: the index posted a 1.5% annual gain for June 2026, yet for the 13th consecutive month U.S. home values fell in real terms, as inflation ran roughly 2 percentage points above that price gain. A nearly nine-percentage-point gap separated June’s strongest market (Chicago, up 6.9% year-over-year) from its weakest (Seattle, down 2.0%), underscoring stark regional divergence. Wherever your grandchild’s parents have settled, you are buying near the top of a market that may not be the same market you would have chosen freely.

Existing home sales have continued to slip, falling to a seasonally adjusted annualized rate of 3.98 million units in August 2026. That is firmly in what the market considers soft territory, and it means that if you ever need to sell, you will be doing it into thin demand. That is the entry price of proximity.

A Working Budget for a Couple Retiring at 65 Near Family

Assume a couple in a mid-tier metro where the kids landed for work, cost of living roughly at the national average. Numbers in current dollars:

• Housing, all-in: $33,600 a year. Modest mortgage or paid-off home with taxes, insurance, and a maintenance reserve at roughly 1.5% of value annually.
• Healthcare: $8,400 for the couple, covering Medicare Part B, a Medigap plan, Part D, and out-of-pocket dental and vision.
• Food: $12,600, aligned with the USDA moderate-cost plan for two adults over 60.
• Utilities and transportation: $9,000.
• Miscellaneous and reserves: $12,000. This is where grandkid life lives: birthday and holiday gifts, summer camp contributions, 529 deposits, travel to see other grandkids, vehicle replacement, and emergency reserves.
• Federal and state tax on withdrawals: $6,000, assuming a blended effective rate on the taxable portion of the drawdown.

That lands around $82,000 a year. It is comfortable, not lavish, and it sits above the $78,535 average annual household expenditure reported in the 2024 Consumer Expenditure Survey, because retirees near family tend to spend more on the miscellaneous bucket. Worth noting for context: the national personal saving rate slipped to 2.7% in June 2026, a nearly four-year low, which is a reminder that even average households are running lean. A retiree drawing down a fixed portfolio cannot afford to make the same mistake.

Turning the Budget Into a Portfolio Number

The average Social Security benefit for an aged couple, both receiving benefits, reached $3,208 per month after the 2026 COLA, equivalent to roughly $38,500 a year. Higher-earning two-earner couples claiming at full retirement age can receive meaningfully more than that average, but using the SSA’s published figure as a floor is the conservative and defensible approach. The 2026 cost-of-living adjustment is 2.8%, and it is now baked into every current benefit check.

Against an $82,000 budget and a $38,500 floor benefit, a couple with average earnings faces a gap of roughly $43,500 a year. Divide that by a 4% withdrawal rate and you get a portfolio target of about $1.09 million in invested assets held outside the primary residence. Higher-earning couples who bring Social Security closer to $50,000 combined narrow the gap to around $32,000, which maps to a portfolio target near $800,000 at the same 4% rate. The range is wide, which is exactly why running the numbers on your specific benefit statement matters before you sign a purchase contract in your child’s zip code.

Push the retirement age down to 60 and the bridge to Medicare alone adds $20,000 to $30,000 a year for five years. That forces a tighter withdrawal rate of 3.3% to 3.5%, which pushes the portfolio target well past $1.2 million even in an average city.

The lever most people miss is claim timing. Delaying Social Security from 67 to 70 lifts the combined benefit by roughly 24%, moving a $38,500 average benefit closer to $48,000 and shrinking the portfolio requirement by $200,000 or more at a 4% rate. If the grandkid metro is expensive, delayed claiming is often the cleanest way to close the gap without saving another dollar.

The Consideration Almost Nobody Prices

Your adult children are mobile assets, and you are not. That variable separates this scenario from every other retirement math exercise.

If you buy a home to be near them and they relocate for a job in year six, you eat a round-trip transaction cost of roughly 8% to 10% of the home’s value in agent commissions, closing costs, and moving expenses. On a $500,000 house that is $40,000 to $50,000 gone. The median price of a previously owned home reached a record $440,600 in June 2026, so the stakes on a forced sale are real. Layer on the fact that services prices rose 2.3% from a year ago in June 2026, which hits healthcare and housing services hardest, and the real erosion of a fixed portfolio during a stuck-in-place stretch adds up quickly.

The structural fix is to rent for the first two years near the grandkids, or to buy a home priced well below what the lender will approve, so a forced sale in a soft market does not vaporize a chunk of the portfolio. Keep an extra 12 months of expenses in short-term Treasuries as a mobility reserve, separate from the normal emergency fund. Think of it as optionality insurance on your children’s career decisions.

State tax is another quiet variable. Retiring near grandkids in Tennessee, Florida, or Texas is a very different portfolio problem than retiring in California or New York. MERIC’s first-quarter 2026 cost-of-living data puts California at an index of 140.5 and Hawaii at 184.8 against a national baseline of 100, with New York coming in around 126. The same $82,000 budget in a high-cost coastal metro is closer to $95,000 to $100,000, and the portfolio target moves from the $800,000 to $1.1 million range to well above $1.2 million on the same 4% rule.

What It Actually Takes

For a couple retiring at 65 in a moderate-cost metro where their children have settled, the realistic starting point is Social Security of roughly $38,500 (average) to $50,000 (above-average earnings), a portfolio sized between $800,000 and $1.1 million in invested assets at a 4% withdrawal rate, a paid-down or modest mortgage, and a clear-eyed look at what their specific benefit statement actually says. In a high-cost coastal metro, the portfolio target shifts to $1.2 million or beyond, and the case for delaying Social Security to age 70 becomes very strong. Retire before 63 and you need a pre-Medicare healthcare bridge plus a tighter 3.3% to 3.5% withdrawal rate, which pushes the target higher still.

Build the mobility reserve. The risk no calculator flags is that the people you moved for might move themselves, and the housing market you would have to sell into is currently soft, elevated, and slow. NAR chief economist Lawrence Yun noted that home sales in August fell due to high mortgage rates, though home prices continued to rise and existing home sales are up 1.6% year-to-date through the first eight months of 2026. That combination of rising prices and thin volume is exactly the market that punishes a forced seller. Price that risk in dollars before you sign, and the near-the-grandkids retirement stops being a leap of faith and starts being a plan.

Editor’s note: This update corrects the services PCE inflation figure to 2.3% year-over-year for June 2026 (per BEA), revises the Social Security couple benefit to the SSA-published average of $3,208 per month ($38,500 annually) with an updated portfolio range to reflect a range of benefit scenarios, and replaces the California and New York cost-of-living index figures with MERIC Q1 2026 data (California 140.5, New York approximately 126 against a national baseline of 100). Existing home sales data has been updated to include the August 2026 reading of 3.98 million units.
