Mortgage from 50: Roadmap for the Years Before Retirement

With the fiftieth birthday, a topic comes to the forefront for many homeowners in Switzerland that had long seemed secondary: the affordability of their mortgage after retirement. While salary, promotions, and family mostly dominated financial decisions for the past decades, banks are now starting to review every extension or increase of the loan from a new perspective. What's decisive is no longer the current employment income, but rather the significantly lower income that will be available in retirement.

Why 50 is the Crucial Turning Point

The Swiss affordability rule is strict. Housing costs—that is, imputed interest of around five percent, amortization, and maintenance—must not exceed one third of gross income. As long as a mortgage holder works full time, this threshold can generally be met without difficulty. With retirement, the calculation suddenly changes: State pension (AHV) and occupational pension together usually amount to about 60 percent of the previous salary. Those who previously earned 150,000 francs will have about 90,000 francs in retirement. The imputed housing costs, however, remain just as high.

That's exactly why banks are required to check affordability for mortgage renewals after age 60 based on the expected retirement income. Those who fail this assessment may, in the worst case, no longer get a renewal and must repay part of the mortgage or sell the property. The period between 50 and 65 is therefore decisive, as it's when the course for the next decades is set.

Calculate Affordability Early

The first step is an honest assessment of your situation. Anyone who is 50 years old today should check affordability for two key dates: once based on current salary and once with the anticipated retirement income. The pension fund can provide a forecast of the retirement assets and the expected pension upon request. Together with the maximum AHV pension, which in 2026 amounts to 2,520 francs per month for singles, this gives a realistic picture of the future budget.

A concrete example shows the dimension: For a mortgage of 800,000 francs on a home valued at one million, the imputed housing costs amount to around 48,000 francs per year, or about 4,000 francs per month. If you have 90,000 francs in retirement income, these housing costs are exactly at the affordability limit. Even a slightly lower pension fund benefit or an unexpected rate hike can tip the balance.

Amortize the Second Mortgage by 65

The most important classic measure is to fully amortize the second mortgage before entering retirement age. In Switzerland, the second mortgage—that is, the portion between 65 and 80 percent loan-to-value—must be repaid within 15 years or at the latest before retirement. If you still have a significant second mortgage at 50, you should review your amortization plan and, if needed, accelerate it.

This reduces the loan-to-value to a maximum of 65 percent, which noticeably lowers the imputed housing costs. In the sample property worth one million, the mortgage would drop to 650,000 francs and the imputed housing costs would fall to around 39,000 francs per year. This makes it much easier to stay below the affordability threshold with less stress.

Use Pillar 3a and Pension Fund Strategically

Voluntary retirement savings offer several levers in the years before retirement. Contributions to Pillar 3a are tax-deductible and can later be used for indirect amortization of the mortgage. Additional purchases into the pension fund reduce taxable income during the high-earning years and at the same time strengthen the later pension, improving the affordability calculation in old age.

The order is important: Pension fund purchases may not be made during the three years prior to a capital withdrawal, otherwise the tax privileges will be retroactively revoked. So, if you want to use pension fund capital for larger amortization before retirement, you must plan these purchases in advance. A staggered strategy over several years helps avoid unpleasant surprises.

Strengthen Negotiating Position with the Bank

With increasing age, banks become more cautious. At the same time, 50-year-olds are attractive clients for most mortgage institutions, with established creditworthiness, completed pension planning, and a stable relationship with the bank. This position can be used to your advantage. Before your next renewal, it's worth comparing providers, especially insurers and pension funds, which often offer lower rates than retail banks.

If you have an offer from a competitor in your pocket, you will often get a discount of 10 to 30 basis points at your principal bank. On a ten-year fixed mortgage of 700,000 francs, that's quickly 15,000 to 20,000 francs less in interest costs. It's important to start negotiations early—ideally twelve to 18 months before the current tranche expires.

Critically Review the Property

An unpleasant but necessary question concerns the property itself. Does the detached house with five rooms and a large garden still fit the post-retirement stage of life? The maintenance costs of older properties increase with each passing year, and energy renovations are becoming mandatory for most buildings from the 1980s and 1990s. If you live in an oversized property in old age, you tie up capital and incur ongoing costs that may no longer be appropriate during retirement.

A sale and move to a smaller condominium or an age-appropriate property frees up equity that can flow into retirement planning while also reducing monthly housing costs. This step is emotionally difficult, but often the most effective financially. Those who consider it early have enough time to implement it in an orderly fashion.

A Roadmap from 50

The following procedure is recommended: At 50, conduct the first comprehensive affordability assessment with a view to retirement age. At 55, review and, if necessary, accelerate the amortization plan for the second mortgage. Between 55 and 60, focus on pension fund purchases and targeted contributions to Pillar 3a. From 60 onwards, begin concrete preparations for the first mortgage renewal after retirement—including comparing banks and negotiating.

Those who follow this roadmap avoid the two most common mistakes in the Swiss mortgage market: postponing uncomfortable decisions and relying on the previous principal bank without comparison. The years between 50 and 65 are the most important for financial security in your own home. Those who make active use of them will continue living in their own four walls after retirement, without falling into the affordability trap.
