It is the fundamental question in later-life housing, and there is no blanket answer: **stay and adapt, or sell and move?** As a rule of thumb: if the location and layout are right, converting is usually the cheaper and emotionally easier option – a barrier-free bathroom and a stairlift together often cost less than the transfer and moving costs. If the house has become too large, too remote or too demanding to maintain, no conversion will fix that. In both cases the timing is what matters: decide from a stable situation, not after a fall.

## What is actually being decided?

It is rarely about the house as such. It is about four things that change independently of one another:

- **Access to daily life.** How far are the shops, the doctor, the post office and the bus stop – and how well does that work without a car?
- **Accessibility.** Stairs, thresholds, the bathtub, the steps down to the laundry room.
- **Upkeep.** Garden, roof, heating, façade. What is a pleasure today can be a burden in ten years.
- **Size.** A house built for four costs as if for four, even when only two people live in it.

Only when you assess these four separately does the answer become clear. An accessible house in a poor location cannot be converted out of that problem. A poorly accessible house in the middle of the village certainly can.

## The case for staying – and what it costs

The strongest reason to stay is rarely structural: it is the neighbours, the family doctor, the route to the hairdresser you could walk in your sleep. That network rebuilds only slowly elsewhere, and in later life it is worth more than a modern floor plan.

Structurally, the most effective measures are surprisingly cheap: grab rails, better lighting and removing thresholds cost little and prevent the most common falls. The big item is the bathroom – replacing a bathtub with a level-access shower typically runs at around CHF 15 000 to 30 000. Depending on the house, a stairlift and wider doorways may follow. Which contributions you can apply for, and why the application has to come **before** the work, is set out on the topic page [Adapting your home](/en/adapting-your-home/).

One point about financing: increasing the mortgage to pay for a conversion is considerably easier while you are still working. After retirement that is exactly where the bottleneck appears – the guide on [mortgages after retirement](/en/blog/mortgage-affordability-after-retirement/) explains why.

## The case for selling

The argument against staying is mainly one thing: running costs and effort that do not shrink as you get older. Banks apply a flat **1 per cent of the property value per year** for maintenance and running costs – on a CHF 1 000 000 house, that is CHF 10 000. This is not an estimate for good years but an average over time that includes the roof, the boiler and the façade.

There is also this: people who have lived in the same house for decades often have several building components reaching the end of their life at the same time. Tackling a heating replacement at 78 is a different exercise from doing it at 55.

## The comparison at a glance

| | Stay and adapt | Sell and move |
|---|---|---|
| One-off costs | conversion, depending on scope | transfer, removal, clearing the house |
| Running costs | maintenance around 1 % of value per year | rent or service charges of the smaller home |
| Tax | none immediately | property gains tax, deferrable in some cases |
| Social network | stays | has to be rebuilt |
| Effort | high once, then lower | high over several months |
| Reversible | yes | no |

That last row is often underrated. A conversion can later be followed by a sale; a sale cannot be undone.

## If you sell: the five mistakes that cost most in later life

**First, the asking price.** It is the single most consequential decision in the whole sale. Too high a price puts off the right buyers, the listing stays online for months and eventually gets a reputation as hard to sell – and the property often ends up going for less than it could have. How a realistic price comes about is covered in the guide on [valuing your home before a move](/en/blog/valuing-your-home-before-moving/).

**Second, incomplete paperwork.** It slows things at two points: buyers cannot assess the property properly, and their bank will not release the financing. After decades in the same house, gathering it takes longer than expected – start early.

| Document | Where to get it |
| --- | --- |
| Current land register extract | Land registry of your district or canton |
| Cadastral plan | Cantonal GIS portal or surveying office |
| Floor plans and building drawings | Your own building file, architect or building authority |
| Building insurance certificate | Cantonal building insurance |
| GEAK energy certificate | Certified GEAK assessor |
| Receipts for value-adding investments | Your own records – they reduce the taxable gain |
| Permits for conversions and extensions | Municipality or building authority |

**Third, time pressure.** Selling takes **three to nine months** from preparation to transfer. Selling because the senior apartment has already been confirmed puts you in a weak negotiating position. Plan backwards – and treat clearing the house as a separate block of time.

**Fourth, property gains tax.** More on that below.

**Fifth, trying to do it all yourself.** The sale, the clearing out and the move all fall in the same period. That is a lot even at 45. Involve the children early and agree who takes which part – not once the notary appointment is already booked.

## Property gains tax and the replacement-property deferral

On sale, the canton or municipality taxes the gain: the difference between the original purchase price plus value-adding investments and the sale price. How much depends on the canton, the gain and the holding period.

There is good news for long-standing owners here: short holding periods attract surcharges in many places, while **long ones earn reductions**. Someone who has lived in the same house for thirty years therefore often pays less than the pure increase in value would suggest. Because the reduction is tied to holding-period thresholds in many cantons, postponing a sale by a few months can be worth real money.

Three things help concretely:

1. **Collect receipts for value-adding investments** – every documented renovation reduces the taxable gain. An age-friendly conversion can count towards this.
2. **Ask your tax office for a provisional calculation** before you list.
3. **Check the replacement-property deferral.** If you use the proceeds to buy another owner-occupied home – including a smaller apartment – the tax can be deferred. It is postponed, not waived. Conditions are set cantonally.

General information on the Swiss tax system is available from the [Federal Tax Administration FTA](https://www.estv.admin.ch).

## The third route: sell and stay put

Between staying and moving lies an option many people overlook: you sell the property and have a **right of residence** or a **usufruct** entered in the land register. Ownership passes; you carry on living there.

This can make sense within the family, where the children will take over the house eventually, or with a third party where capital is needed. The purchase price is correspondingly lower, because the buyer cannot use the property for now. The difference between a right of residence and a usufruct – and what each triggers for tax – is covered in the guide on [passing on property](/en/blog/inheriting-property-switzerland/).

## Summary

- Assess access, accessibility, upkeep and size separately – the answer follows from those, not from a gut feeling.
- If the location and layout are right, converting is usually cheaper than moving and preserves your social network.
- Budget around 1 per cent of the property value per year for maintenance and running costs, regardless of how many people live there.
- A sale takes three to nine months; clearing the house comes on top of that.
- After a long holding period the property gains tax is often more moderate than feared – and can be deferred by buying a replacement home.
- Converting is reversible, selling is not. In case of doubt, that is an argument for doing them in that order.

## Frequently asked questions

### When should you start thinking about selling the family home?

Ideally before an event forces the decision. Selling from a stable situation gives you three to nine months, a strong negotiating position and the ability to optimise the timing for tax. Selling under pressure after a fall or a diagnosis usually means taking the first price offered.

### Does an age-friendly conversion pay off compared with selling?

Often yes, if the location and layout are right. A barrier-free bathroom and a stairlift together frequently cost less than the transfer and moving costs of a move – and you keep your surroundings. Against conversion: a house that is too big for two people, too far out, or whose upkeep already overwhelms you.

### How much is property gains tax when selling a Swiss home?

It depends on the canton, the gain and how long you have owned the property. Short holding periods attract surcharges in many places, long ones earn reductions – so after decades in the same house the tax is often more moderate than people fear. Ask your tax office for a provisional calculation before you list.

### What is a replacement-property tax deferral?

If you use the proceeds to buy another owner-occupied home in Switzerland, the property gains tax can be deferred – it is not waived but postponed until you sell the new property. This applies to downsizing into a smaller apartment too, but only for the reinvested portion. Deadlines and conditions are set by each canton.

### Can I sell my house and still live in it?

Yes, through a right of residence or a usufruct entered in the land register. You give up ownership, receive the proceeds or an annuity, and stay living there. The purchase price is correspondingly lower because the buyer cannot use the property for the time being. Both arrangements need professional advice and proper notarisation.

### How long does selling a house in Switzerland take?

Usually three to nine months from preparation to the transfer of ownership. Allow additional time for clearing the house – after decades in the same home that is often the more demanding part and takes several months of its own.
