• I'm 67 and am still working 5 days a week. Many of my friends have retired, but I can't afford to.
• I regret not investing in a pension offered to me earlier in life.
• Now I'm planning to move away from my grandchild so I can work less and enjoy a lower cost of living.

I am 67 years old and when people ask me if I've retired yet, my knee jerk response is, "No I haven't! What's retirement?"

I am a Psychologist, was formerly a teacher, and have worked and paid taxes all my life. I am well paid for the work that I do. I have paid my mortgage off and have no outstanding debts. In spite of this, I am now faced with the prospect of living on a state pension, which is just not possible, continuing to work or, as I have now decided, selling up and moving 200 miles away from my only granddaughter so I can live in a location where house prices are lower and I can afford to work less.

This wasn't the plan

It didn't start out this way. I once imagined that somehow I would make such a success of my life that I would be able to retire at 50 or younger, enjoying being a lady that lunches, going on cruises, and doing the odd spot of volunteer work. But I didn't actually have a plan.

I started my working life as a teacher, got married at 30 then found myself to be a lone parent when my children were 2 and 5, with no family support. I was not well advised and ended up with the children, the mortgage, no pension, and an ex-husband who tried his best not to pay anything at all.

Around that time I decided I needed a career change, and started to train as a Psychologist, a long and very expensive process. I'm not quite sure how I did it, but I managed to work, study, and raise children — all on my own.

I was proud of what I accomplished, but had nothing at all in the way of savings; life was a constant struggle to make ends meet. I still did what I could and at 40 I started to pay £100 (about $127 USD) a month into a private pension. Now I know that I was badly advised and if I were to take it, this would only pay me around £1,500 (about $1,905 USD) per year —nowhere near what I would need to live on.

The thing I never did with my money still haunts me

The obvious question is, why didn't I pay into the teacher's pension offered to me earlier in my career? Why indeed.

Not taking advantage of this is one of my greatest regrets. But when I was in my early 20s we didn't have any financial education. Even the teachers' unions didn't send out advice about pensions. To me, it just seemed like a large monthly outgoing from an already meagre salary, so I opted out and didn't give it another thought. Now I know that money would have made a big difference. Hindsight is a wonderful thing.

I needed to make some tough decisions

I realized around 5 years ago that the only way I could even contemplate retirement would be to downsize and move to a cheaper area in order to have a reasonably substantial nest egg to help me eke out my twilight years. Most of the advice I have read claims that to have a comfortable retirement where I live, one needs a gross annual income of around £40,000 (around $50,802 USD). I have calculated that with my state pension, bits and pieces for my writing, and interest on the surplus when I move, to reach that £40,000 I will still need to work at least one day a week. Not perfect, but a lot better than the five days I have been working.

With this in mind, I put my house on the market. Then my eldest daughter, who lives nearby, announced that she was pregnant. Fantastic as that was, I could no longer imagine moving away, so I carried on working five days.

I'm now more than a year past the typical retirement age and most of my friends seem to be enjoying a fruitful, active retirement. Meanwhile, I'm becoming more and more exhausted, suffering from frequent low-level infections, and becoming increasingly resentful.

Change is coming

Now, my house is back on the market. I will be moving to Derbyshire, where my younger daughter lives and where house prices are around half of those where I live now.

It will be a massive wrench, especially leaving my granddaughter, but I need to do it while I'm still fit and healthy. I have lived in my current house for 38 years and expected to leave it in a box. I've worked out a solution, although not ideal. I will have enough income to work one day a week, more time to focus on my passions, I'll be able to travel and get involved in the local community and still be able to visit my granddaughter every 6 weeks or so.

My advice to young people now? However distant it seems, don't leave it to chance. Make a retirement plan and start paying as much as you can into a good pension. The years fly by and it will be here before you know it.

• Christine Wilder-Abrams began to struggle with the stairs of her two-story house in California.
• She didn't want to leave her home of 35 years, so she built an ADU, or "granny pod," in the yard.
• Her 34-year-old daughter now lives in the main home, which Wilder-Abrams calls a win for them both.

In 2021, Christine Wilder-Abrams started to struggle with the stairs in her two-story home in Oakland, California.

She wasn't ready to give up the home or neighborhood she had lived in for nearly 35 years, so she found a solution: build a one-story accessory dwelling unit, or ADU, in her backyard that she could live in, then ask her daughter to move into the main house.

"I was ready to downsize and have a smaller place to live and take care of," Wilder-Abrams, 72, told Business Insider. "The home is in an urban area, so there are a lot of possibilities for my daughter, too."

ADUs have become a popular alternative to traditional apartments or houses, in part due to their relative affordability and how little land they require.

These smaller units, typically 150 to 1,200 square feet, cost between $100,000 and $300,000 to build on average. However, additional expenses, such as inspections, utility installations, and permitting fees, can add to the cost.

An analysis of Google search data shows growing interest in "granny pods," or small outbuildings where older relatives or family members who need extra support can age in place while maintaining independence and personal space.

Wilder-Abrams, 72, now lives in the 560-square-foot, one-bedroom, one-bathroom tiny home that she financed and built for about $350,000. Meanwhile, her 34-year-old daughter lives in the 2,000-square-foot, three-bedroom, two-bathroom main house with her three-and-a-half-year-old daughter.

The ADU was a win for mom, daughter, and granddaughter

For Wilder-Abrams, building an ADU in her backyard and having her daughter move into the main house was much more affordable than purchasing a new home in Oakland.

Wilder-Abrams said that her family home, purchased in 1987 for about $230,000, is now valued at over $1 million. As of October, the median home sale price in Oakland was $751,455, according to Zillow.

"It's hard for me to believe houses cost that much today," she said. "How can anybody afford it?"

Beyond affordability, ADUs also offer families an added sense of security. They're a practical solution for adult children or aging parents who want to maintain their independence while still having access to support.

Wilder-Abrams said that the new living arrangements have benefited her and her daughter, who was widowed in October 2023, equally.

"I get to live close to my daughter and granddaughter," she said. "It's nice that I'm here for them."

Wilder-Abrams especially loves seeing her granddaughter regularly. "It's great watching her grow up," she added.

The construction process of the ADU

Wilder-Abrams' tiny home was built by Inspired ADUs, an ADU builder operating in Oakland, Orange County, and the greater Bay Area, which she found online.

Inspired ADUs offers over 70 different layouts, ranging from 300-square-foot studios to two-story units exceeding 1,200 square feet. Prices start at $13,800 for pre-designed or custom ADU plans, $215,000 for panelized kits, and up to $314,000 for a full prefabricated unit. The company also manages the permitting process for its clients.

"The permitting process was really easy," Wilder-Abrams said. "The architect said it'll take about three months, and it took three months."

Construction on Wilder-Abrams' ADU began in 2021. By May 2022, her daughter had moved into the main house, and she had settled into the ADU.

To finance the construction of the ADU, Wilder-Abrams took out a second mortgage on her home, as the original mortgage had been paid off years earlier. She now has a monthly mortgage payment of $1,500, which her daughter pays as rent.

Downsizing can be difficult

Wilder-Abrams' ADU has an open floor plan with high ceilings, large windows, and brand-new European appliances, including a refrigerator, dishwasher, stove, oven, and stackable washer and dryer. Her new home also has its own patio and garden.

"My ADU feels very spacious," she said. "Everybody's surprised by how big it is."

Despite the generous size of the ADU, Wilder-Abrams had to part with many belongings, including most of her longtime furniture — such as her couch and dining room table — as well as items that had belonged to her husband and both of their parents.

"Downsizing is hard. You really have to want to do it," she said.

Wilder-Abrams now has an apartment-sized L-shaped sofa, and instead of a dining table, there's a built-in bench in the ADU where she eats.

"I think having less stuff is freeing. There are just fewer things for me to take care of or worry about all the time," she said.

Wilder-Abrams has more security

Swapping homes with her daughter wasn't something Wilder-Abrams had envisioned years ago, but it's turned out to be a surprisingly successful arrangement for both of them.

"I wasn't sure if she would want to return to her childhood home, but she's happy about it," Wilder-Abrams said.

Another benefit is the support she has received as she ages. Last year, Wilder-Abrams had knee surgery, and she said her recovery would have been much more challenging without her daughter nearby.

"The first few days, she stayed with me to change the ice packs regularly," she said. "It was so convenient for both of us."
