Sell or let? The decision guide for owners

You are moving, have inherited or need capital – and wonder: sell or let the house? Yield, taxes, effort and risk compared, with a worked example for the Baselbiet.

Anyone who no longer lives in a house themselves has two options: sell and invest the capital elsewhere – or let and generate long-term income. Both can be right. The only wrong thing is to decide on gut feeling.

In brief

  • Letting pays off if the net yield exceeds alternative investments and you are willing to bear the effort
  • Selling pays off if you need capital, can use the replacement purchase or the house needs renovation
  • Tax-wise: on sale, property gains tax once; when letting, income tax on the rental income every year
  • At ImmoBilà both routes only cost on success – we calculate both for you

The decisive questions

  • Do I need the capital – for a new home, retirement, the children?
  • Can I use the tax deferral via replacement purchase (only when selling and buying again)?
  • What is the condition? Major renovations (roof, heating, façade) burden the yield for years
  • Do I want to deal with tenants, repairs and statements – or pay for it?
  • How is the location developing? Good locations in the Baselbiet have gained a lot of value in 15 years

Calculating the yield realistically

The gross yield (annual rent ÷ market value) often looks good. What counts is the net yield: after deducting maintenance and reserves (1–1.5 % of the building value per year), management, insurance, vacancy risk and mortgage interest, single-family homes in the Baselbiet usually leave a net yield of 2 to 3 % on the market value. Similar for condominiums with a renovation fund. On top of that comes the possible increase in value – which nobody guarantees, however.

Taxes: two worlds

  • Selling: property gains tax once (3–25 % on the gain) and transfer tax 1.25 % – deferrable with a replacement purchase
  • Letting: rental income is income every year and increases the progression; the property counts towards taxable wealth; in return, maintenance, management and debt interest are deductible
  • Selling later: the property gains tax is still due – only later, but with a longer holding period

Effort and risk

Letting a single-family home is more work than a flat in an apartment building: garden, heating, roof and grounds are the owner’s responsibility. A change of tenant every few years means vacancy and refurbishment. Anyone not wanting to bear the effort themselves budgets 4–6 % of the rental income for management. Risks: rent losses, tenant damage, rising interest on the mortgage.

Worked example single-family home Füllinsdorf

Market value CHF 1,000,000, mortgage CHF 400,000 at 1.7 %

Letting: market rent around CHF 2,900/month = CHF 34,800/year. Less maintenance/reserves CHF 9,000, insurance/management CHF 3,000, mortgage interest CHF 6,800, vacancy reserve CHF 1,400 → net income around CHF 14,600 = 2.4 % on the equity of CHF 600,000 before tax. Sale: proceeds CHF 1,000,000, repayment of the mortgage, property gains tax depending on investment costs (with a gain of CHF 240,000 around CHF 60,000, deferred with a replacement purchase). Freely available capital around CHF 540,000–600,000.

Conclusion and decision guide

  • Sell, if: need for capital, replacement purchase possible, renovation backlog, no interest in management, community of heirs without a common line
  • Let, if: no need for capital, good location with potential for value growth, property in good condition, willingness for the effort or budget for management, children to move in later
  • Combine both: let first, sell in 5–10 years with a longer holding period – if the market allows

Frequently asked questions

Questions on this topic.

Can I let the house and sell it later with a replacement purchase?

No – the replacement purchase requires owner-occupation until the sale.

  • Anyone letting in the meantime loses the deferral
  • Exception: short transitional letting – clarify case by case with the tax administration
What about the imputed rental value if I let?

It no longer applies – instead you pay tax on the actual rent.

  • Maintenance, management and debt interest remain deductible
How quickly will I find a tenant for a single-family home?

In the Baselbiet usually within 4 to 8 weeks – single-family homes to rent are rare.

  • Prerequisite: a market-based rent
  • Families often look for the start of the school year
