I want to buy the land next to my house for $1.7 million to build a playground for my kids – can I afford it?

One of the clearest advantages of the fat or chubby FIRE lifestyle (financial independence, retire early) is the freedom to make meaningful improvements to your quality of life without second-guessing every dollar. That freedom shows up most vividly when someone can buy land or a larger home that serves the family today and holds value for years to come.

That is precisely the situation facing one Redditor who posted in r/fatFIRE. With a net worth of roughly $12 million, this poster is weighing a major financial decision that carries both immediate lifestyle benefits and longer-term implications. Specifically, he is considering buying the tear-down house next door and keeping the land.

Timing shapes the backdrop. The 30-year fixed mortgage rate averaged 6.65% for the week ending August 20, 2026, according to Freddie Mac, up from a brief dip below 6% in late February before rates climbed back through spring and summer. Many high-net-worth individuals in this environment bypass traditional financing altogether, using all-cash transactions or asset-backed credit lines to keep lifestyle acquisitions clean and fast. Meanwhile, national home price appreciation has essentially stalled. The S&P Cotality Case-Shiller National Home Price Index posted a year-over-year gain of just 0.8% through April 2026, barely above March’s 0.7% pace, with a nearly nine-percentage-point gap separating April’s strongest market (Chicago, up 6.5%) from its weakest (Seattle, down 2.3%). Realtor.com’s midyear forecast projects full-year 2026 home price growth of only 1.2%, a rate below the current pace of inflation. At that level, the purchase functions less as a high-growth investment and more as a land bank anchored to lifestyle value.

The Scenario

The Redditor is in his mid-40s, has three children, and lives in a very high-cost-of-living area. His family’s net worth sits at approximately $12 million, built from $15 million in assets against a $3 million mortgage. The current home is worth about $4 million, with $1 million of equity already folded into that net worth figure. What makes the adjacent property compelling is its character: a teardown available for around $1.7 million, which the Redditor is seriously considering clearing and converting into private open space for his kids.

There is a meaningful tax angle worth understanding. Under IRS Publication 523, the sale of vacant land adjacent to your primary residence can be treated as part of a single home sale, provided the land and home are sold within two years of each other and both meet the ownership and use tests. For a married couple filing jointly, the combined gain from both sales could be sheltered by the $500,000 primary-residence exclusion. That is a genuine long-term benefit, but it comes with strict conditions: the buyer must have owned and used the vacant land as part of the home, and both sales must either meet the Eligibility Test or qualify for partial tax benefits. A tax professional should be consulted before assuming the exclusion will apply. Beyond taxes, carrying costs add up in a high-cost market. Ongoing maintenance, landscaping, and property taxes on a bare parcel can represent a meaningful annual drag on liquidity, and those costs deserve a real place in the budget.

Strategic Asset Management

It is rare to find a Reddit comment section in broad agreement, but this thread leans heavily toward buying. The original poster’s main hesitation is opportunity cost relative to a $50 million net worth target, but commenters push back on that framing with good reason. At a $12 million net worth, a $1.7 million outlay represents roughly 14% of total assets. That is a real number, but it does not threaten the family’s financial independence. And unlike most discretionary purchases, land adjacent to a primary residence holds residual value. If market conditions shift, the parcel could be sold for a reasonable recovery.

The core case for buying rests on a straightforward observation: privacy and space are genuinely scarce in high-cost markets, and their value tends to compound over time. A $1.7 million outlay in this context is a durable lifestyle upgrade, not a consumption expenditure. The capital stops being liquid, but it does not disappear.

Just Do It

Whatever net worth target this Redditor is chasing, the more pressing question is whether a unique opportunity is about to slip away. The house next door does not come up for sale on a regular schedule. The financial math is sound. Watching his children play on that land is a return on investment that no diversified portfolio can replicate, and with a $12 million balance sheet behind the decision, the answer is clear: make the purchase.

Editor’s note: The 30-year fixed mortgage rate was updated to 6.65%, reflecting the Freddie Mac Primary Mortgage Market Survey for the week ending August 20, 2026; the prior claim that rates were not expected to fall below 6% was corrected to note that rates did briefly touch 5.98% in late February 2026 before rebounding. The Realtor.com midyear 2026 home price forecast of 1.2% growth and regional Case-Shiller detail (Chicago up 6.5%, Seattle down 2.3% in April 2026) were also added.
