You sell your house. You stay living in it as a tenant. Decades pass. Then your landlord dies—and leaves you the property.

It sounds like the plot of a feel-good novel, but according to New Zealand financial columnist Mary Holm, it's a real scenario that recently unfolded—and it offers a master class in both the promise and peril of sale-leaseback arrangements.

Writing in the NZ Herald, Holm recounted the case as part of her ongoing coverage of retirees who sell their homes to unlock equity while negotiating the right to remain as tenants. The arrangement—sometimes called a "sale and rent-back"—has gained traction in countries with aging populations and expensive housing markets. The pitch is seductive: cash out your biggest asset without the upheaval of moving.

But as Holm's example illustrates, these deals are anything but simple.

The Windfall No One Expected

The details are sparse, but the outline is clear. An elderly homeowner sold their property to a buyer—likely a neighbor or acquaintance—and stayed on as a tenant under a long-term lease. Years later, the landlord died and bequeathed the house back to the original seller, now well into their twilight years.

Holm presents the case as a curiosity, but it's also a reminder that sale-leaseback deals hinge entirely on trust, legal clarity, and—let's be honest—luck. The tenant in this story got lucky. The landlord could just as easily have sold the property to a third party, raised the rent to market rates, or left it to someone with no sentimental attachment to the arrangement.

"This story should be of interest to your readers," Holm wrote, "in light of recent Q&As about selling your house to your neighbour and then living in it as a tenant."

She's right. It should be.

Why Retirees Are Tempted

Sale-leaseback deals appeal to a specific slice of the retirement population: people who are house-rich but cash-poor. You've paid off the mortgage. The house is worth a fortune. But your pension doesn't stretch far, and you don't want to downsize or move into a retirement village.

Selling to a trusted buyer—a family member, neighbor, or friend—can provide a lump sum for medical expenses, home repairs, or simply a more comfortable retirement. In exchange, you pay rent, often below market rate, and retain the right to stay in the home for a fixed period or for life.

New Zealand, like much of the developed world, is grappling with an aging population and a housing affordability crisis. KiwiSaver, the country's voluntary retirement savings scheme, helps—but many retirees still find themselves asset-rich and income-poor. Sale-leaseback arrangements offer a way out of that bind.

Or so the theory goes.

The Risks You're Not Told About

Here's what the glossy brochures don't mention: you're giving up ownership. That means you're also giving up control.

If the buyer decides to sell, you could be evicted. If they die, their heirs might not honor the arrangement. If they fall into financial trouble, the property could be seized by creditors. Rent can be increased. Maintenance responsibilities can shift. And if the deal isn't structured properly, you could face unexpected tax liabilities or lose eligibility for certain benefits.

Legal protections vary by jurisdiction, but in many cases, tenants in sale-leaseback deals have fewer rights than standard renters. And because these arrangements are often informal—handshake deals between neighbors or relatives—disputes can turn ugly fast.

Holm has been covering these scenarios for years, and her columns are littered with cautionary tales. The 120-year-old's windfall is the exception, not the rule.

Who Benefits?

The real winners in sale-leaseback deals are often the buyers—especially institutional investors who have entered the market in recent years. Companies in the UK, Australia, and New Zealand now specialize in purchasing homes from retirees and leasing them back, often at terms that heavily favor the buyer.

These firms offer below-market prices, charge above-market rents, and impose strict lease terms. The retiree gets immediate cash, but at a steep cost. And because the deals are complex and emotionally charged, many sellers don't fully understand what they're signing.

Consumer advocates have raised alarms. In the UK, the Financial Conduct Authority has warned that sale-and-rent-back schemes can leave vulnerable people worse off. New Zealand doesn't have equivalent regulations, which means retirees are largely on their own.

The KiwiSaver Angle

Holm's column also touched on KiwiSaver withdrawals at age 65—a separate but related issue. KiwiSaver allows members to withdraw their savings once they hit the eligibility age, but many retirees face a dilemma: take the money now, or leave it invested for growth?

The question ties back to the same underlying problem: how do you fund a retirement that could last 20, 30, or even 40 years? Selling your home and renting it back is one answer. Drawing down KiwiSaver is another. Both come with tradeoffs.

The retiree who inherited their house back likely didn't have to make that choice. But for everyone else, the math is unforgiving.

What You Should Do Instead

If you're considering a sale-leaseback, get independent legal and financial advice. Not from the buyer. Not from a broker with a commission on the line. From someone who works for you.

Ask hard questions. What happens if the buyer dies? What happens if they want to sell? Can the rent be increased? What are your rights as a tenant? Is there a better way to access your home equity—like a reverse mortgage or a home equity loan?

And be honest about why you're doing this. If it's because you're desperate for cash, a sale-leaseback might just be kicking the problem down the road.

The 120-year-old's windfall is a heartwarming story. But it's also a fluke. Don't bet your retirement on one.
