Buying a home with a B permit: check purchase rights and financing separately
EU citizens whose main residence is in Switzerland face different property rules from people living abroad.
Updated 30 September 2026Buying a home with a B permit: ask the right question
Many people living in Switzerland with a B residence permit ask whether they may buy a home. The permit alone does not provide the whole answer. Legal acquisition depends on nationality, lawful and actual residence in Switzerland, the type of property and its intended use. An owner-occupied main home differs from a holiday home or a property held purely as an investment. The Federal Act on the Acquisition of Real Estate by Persons Abroad, commonly called Lex Koller, distinguishes these situations. The competent authority in the canton where the property is located gives the binding assessment of an individual case.
The financial examination is separate. A bank asks about property value, equity, income, existing obligations, repayment and affordability. Legal permission to acquire ownership does not constitute a financing promise. Conversely, a preliminary mortgage approval does not replace a check that this particular property may legally be acquired. Both matters should be resolved before buyers sign a binding contract or make a large advance payment.
Zurich provides information on property acquisition by persons abroad, and the Federal Office of Justice publishes legal guidance and answers to frequent questions. Official sources matter especially because amendments to Lex Koller were proposed in 2026. A proposal submitted for consultation is not automatically law in force. This article reflects information available on 30 September 2026; anyone contemplating an actual purchase should confirm the current legal position immediately beforehand. A long search can span legal changes, so an early informal answer should not be treated as permanently valid.
EU and EFTA citizens resident in Switzerland
According to Zurich's official guidance, EU and EFTA nationals who are lawfully and actually resident in Switzerland are not classified as persons abroad for Lex Koller purposes. In that respect they are treated like Swiss nationals when acquiring real estate. For a Portuguese citizen genuinely resident in Zurich, a B rather than C permit is therefore not itself a separate exclusion in the usual mortgage affordability calculation. Identity and residence still have to be evidenced. Special properties can also be subject to other public-law requirements.
Actual circumstances matter. A registered address may not suffice if the centre of a person's life remains abroad. Someone intending to move but not yet resident in Switzerland is in a different position from someone already living here. Cross-border cases also need separate attention. The Federal Office of Justice explains that people resident abroad can be subject to restrictions even where they have EU or EFTA nationality. Frontier workers have specific rules and should not be treated as ordinary residents buying their principal home.
This legal equality says nothing about the mortgage amount. Swiss nationals, too, receive financing only when the property, equity and affordability satisfy a lender's policies. A well-prepared file with income, wealth and property evidence is important for everyone. The residence document is supplied as part of identity and domicile evidence; it does not replace a valuation or a credible repayment plan. A bank may request several documents at once, but the reasons for legal acquisition checks and credit-risk checks remain distinct.
Third-country citizens holding a B permit
People who are nationals of countries outside the EU and EFTA face a narrower legal position. The Federal Office of Justice explains that a person lawfully and actually resident in Switzerland may, under the rules currently in force, generally acquire a dwelling or detached house as their own main home at that place of residence without an acquisition permit. This commonly concerns a person with a B permit. The property must genuinely serve as a main home for the person and their family. Building land, several units, unusually extensive plots or a different intended use can raise additional questions. A blanket claim that a B permit permits every property purchase would be wrong.
Someone wanting a holiday apartment, buy-to-let property or a home intended for later letting cannot simply extend the main-home exception to that purchase. Other rules apply and the transaction may need authorisation or be impermissible. The cantonal authority and land registry assess the particular facts. Disclose the intended use to the notary or competent authority before making a reservation payment. If the planned use changes while the purchase is in progress, update the information rather than assuming the original explanation remains sufficient.
In April 2026 the Federal Council opened a consultation on tightening Lex Koller. One proposal would require an acquisition permit in future for principal homes bought by third-country nationals. At this article's date, it was a legislative proposal, not a blanket rule already governing every ongoing purchase. Because the position may evolve, verify the current law immediately before acquisition. Legal advice obtained months earlier may need updating if a property search or financing negotiation takes longer than expected.
What changes with a C settlement permit
A person who holds a C settlement permit and actually resides in Switzerland is generally treated like a Swiss national under the Lex Koller rules, according to Zurich and federal information. This addresses the property-acquisition question. Other rules governing the property, such as planning, building permission or condominium restrictions, still apply. Nor does a C permit make a holiday home automatically affordable or waive contractual obligations. The mortgage credit assessment remains separate.
A change from B to C should not be assumed to produce better mortgage prices or a higher lending limit automatically. Conditions depend on lender policy, income, lending value, equity and the chosen mortgage structure. A broader legal range of potential acquisitions may influence the search, but it does not create additional income. If a suitable principal home can already be purchased lawfully with B and financing is sound, the buyer need not assume that ownership must always wait until C is granted.
For legal clarification, prepare a description of the specific facts: nationality, residence status, actual home, desired property and intended use. For financing, add salary certificates, tax documents, evidence of equity and a property valuation. Separate folders let the notary handle acquisition and the lender assess affordability efficiently. That prevents an unresolved legal question being mistaken for an inadequate equity percentage. If a condition of the purchase depends on a permit or official confirmation, make sure the contractual timetable reflects the time needed to obtain it.
Main residence, second home and investment property
The intended use of a property has a strong influence on acquisition rules. A main residence is the actual centre of life for the buyer and family. A second home is used in addition to another home; a holiday property is occupied mainly for temporary stays. An investment property is held primarily to let and earn income. These are not merely marketing labels. Describing a property as a principal home in a contract while intending to let it from the outset can create legal problems. Stated use needs to match reality.
For a third-country citizen with B, the main-home exception is central. Other uses require a separate check with the competent canton. EU or EFTA citizens actually resident in Switzerland and people with C have a different Lex Koller position. Still, holiday homes can face local quotas, second-home provisions, building rules or use restrictions. Every particular property must be assessed with its location and legal attributes in mind.
Financing differs as well. Banks assess an owner-occupied home differently from a rented property. Rental income, vacancies, maintenance and lending ratios matter more for an investment property. FINMA stresses that lenders should set segment-specific risk-appropriate equity and amortisation requirements. Someone planning to occupy a home first and let it later should discuss this early. A loan calculated solely for continuing own use may need reassessment after a change of use. The planned financing product, insurance and tax treatment can change at the same time.
Check the legal position before a purchase commitment
Start with the official information from the Federal Office of Justice and the canton where the property is located. Describe nationality, permit, actual residence, property type and intended use rather than asking only whether a B permit is enough. Where the treatment is unclear, the cantonal authorisation authority can decide whether the specific transaction requires a permit. The Federal Office of Justice explicitly points to cantonal implementation and case-by-case decisions. A property advert or a casual phone comment from a mortgage adviser cannot replace this review.
The notary and land registry need the relevant legal details to complete the transfer. Ask in good time what evidence is necessary and whether a formal ruling or authorisation is required. If the transaction depends on lending or an authority's decision, the purchase contract should address that risk. Even a reservation agreement can create payments and obligations. Understand its terms before signing, especially if there will be a long interval between reservation and notarisation. Recheck any change of law or residence status during that interval.
The Federal Office of Justice also makes clear that owning Swiss real estate gives a foreign national no entitlement to a residence permit. This matters where a purchase is part of a planned move. Immigration permission and real estate acquisition are different questions. Someone not yet resident should clarify residence rights independently of the purchase. A lender may also make financing contingent on the lawful transaction and formal transfer of ownership. Resolving the steps in the right order avoids a costly contractual commitment based on a misunderstood status.
Financing: the same core questions for buyers
For a mortgage, the lender principally asks whether the property is suitable security and whether the household can sustainably service the debt. It reviews market value, sufficient equity, the source of funds, composition of income and amortisation plan. For an owner-occupied home, a model with roughly 20 percent equity is common. Recognised minimum standards require at least 10 percent of lending value from sources other than occupational pension withdrawal or pledge. The lender can require more, notably if it values the property below the purchase price.
An affordability calculation typically includes imputed interest, maintenance and required amortisation. The often quoted guide of approximately one third of gross income is an orientation, not a statutory limit. Lenders may treat income and costs differently. Multiple income sources need an assessment of stability. Self-employment, variable bonuses and a new employment contract should therefore be explained with evidence. A B or C permit is not a numeric step in this formula. A legal acquisition check may be necessary, but it should not be represented as a line in an interest or affordability bar.
A realistic plan preserves a reserve after the deposit. Notarial and land-register charges, moving costs, renovations and maintenance may arise soon after purchase. Anyone using pension money should understand the effect on retirement, disability and family protection. Financing and pension planning intersect here. For someone with only a few years of Swiss employment, it is especially useful to read the pension-fund statement and assess gaps, without assuming that the gap itself permits a higher mortgage.
Example: a Portuguese family in Zurich
A Portuguese family has lived lawfully and actually in Zurich for several years. Both adults have B permits and want to buy a condominium apartment as their shared main residence. As EU citizens resident in Switzerland, they are generally not classified as persons abroad under the cantonal Lex Koller guidance. The B permit should therefore not be turned into a special financial test in a mortgage calculator. Identity, domicile and details of the property still need to be documented for the transaction.
The apartment costs CHF 900,000 in this example, and the bank also values it at CHF 900,000. The family proposes CHF 180,000 in equity, at least CHF 90,000 of which is not sourced from the occupational pension scheme. The requested mortgage is CHF 720,000. The bank then examines both incomes, any anticipated part-time work, existing obligations, imputed housing costs and amortisation of debt above two thirds of lending value. It can decline financing despite the clear legal acquisition position if affordability is insufficient. Conversely, strong affordability cannot remove a legal acquisition restriction.
The family also checks the heating system, renovation fund and planned work of the condominium association. The simple question Can we buy with B? becomes a sensible sequence: establish legal eligibility, value the property, prove the equity, examine income and risks, and choose a mortgage strategy. This structure is particularly useful for internationally connected households because it assigns distinct questions to the appropriate authority, notary and lender.
Example: a third-country buyer with B
A national of a country outside the EU and EFTA lives in Winterthur with a valid B permit and an actual home there. They wish to buy a detached house in Winterthur for themselves and their family. Under the rules described by the Federal Office of Justice, acquiring such a principal home without an acquisition permit can generally be possible if all conditions are satisfied. The buyer should disclose residence and planned personal use to the notary. If the plot includes developable land, several dwellings or a planned tenancy, the legal classification needs separate examination.
Meanwhile the bank compares purchase price with its own market valuation. It asks for evidence of savings, income and any pension assets. If part of income comes as a bonus, it examines stability. The necessary amortisation is included in the affordability test. That financial assessment is independent of whether the legal acquisition is permit-free. If an adviser asks about B or C, clarify whether the question relates to proof of residence for the transaction or to a specific internal lending requirement. Do not merge the two purposes.
The same person then considers a holiday apartment in another canton. The exception for the primary residence does not cover that second purchase. Separate Lex Koller rules and possibly cantonal restrictions apply. An individual check with the authorities is needed before an advance payment. This illustrates why a guide giving only yes or no to a B permit would be unhelpful: the intended use can change the legal answer substantially. The financeability of each purchase also has to be calculated in its own right.
Taxes and pension provision alongside home ownership
Owning a home has tax effects beyond interest and maintenance. Until the end of 2028, owner-occupied property generally remains within the current imputed-rental-value system with related rules for interest and maintenance costs. The Federal Council has put the reform into force from 1 January 2029. At that point, imputed rental value on owner-occupied property disappears and many deductions change significantly. A buyer in 2026 should not build a long-term amortisation plan solely on today's deductibility of mortgage interest. The exact result depends on wealth, rental property, first-buyer status and cantonal rules.
Energy renovation also deserves separate planning. Ask what investment the property will need over the medium term and whether work preserves value, enhances it or does both. The tax rules for 2026 and 2028 may differ from those from 2029. Zurich publishes guidance on allocating maintenance expenses. Invoices should describe the work clearly enough to support the distinction. Subsidies and a condominium association can change who bears which cost. A renovation may make financial sense even if the tax deduction is smaller than hoped.
Using occupational pension assets or pillar 3a for equity reduces or pledges pension savings. Assess the effect on retirement income, disability and survivors' protection. This is especially important for families with children or dependants abroad. An uncovered pension risk may be financially more serious than a small difference in mortgage interest. Sound advice therefore connects the property, financing, family protection and long-term liquidity, rather than treating residence-permit type as a substitute for those questions.
Checklist and frequent questions
For the legal review, collect nationality, residence document, actual domicile, property address and intended use. Ask the competent cantonal authority where the classification of main home, investment, second home or building land is uncertain. For financing, prepare price, market valuation, evidence of equity, salary statements or business accounts, liabilities and an amortisation plan. For the property, collect condition reports, renovation quotations and condominium reserve documents. Resolve open issues before making a binding purchase commitment.
May an EU citizen with B buy in Zurich? With lawful and actual residence in Switzerland, they are generally treated equally for Lex Koller purposes, although the actual transaction still needs checking. Can a third-country citizen with B buy a main home? Under the current position, this can be possible without authorisation if specific conditions are met. Does that extend to holiday homes? No; those need a separate legal assessment. Is C always a prerequisite for a mortgage? That blanket statement is wrong; the financial check considers property, equity and affordability. Legal acquisition must be resolved separately.
Does owning a home grant residence rights? No. The Federal Office of Justice explicitly says it does not. Were the Lex Koller amendments proposed in 2026 already law? A consultation does not equal entry into force; check the current legislative position before buying. Answering these questions in the right sequence lets buyers find an appropriate property and prepare financing without drawing false financial conclusions from a permit type. Written clarification is particularly valuable for complicated ownership structures, building land or a plan to let the property later.
