Everything owners want to know before selling or letting.
What you pay at ImmoBilà – and what you don’t.
What does selling through ImmoBilà cost me?
A commission from 1 % of the sale price – only on success.
- Valuation, photos, documentation, listings, viewings: included
- No advance payment, no flat fee if unsuccessful
- For comparison: 2–3 % plus VAT is usual
When and how do I pay the commission?
Only after the sale.
- Due after notarisation at the notary
- Usually settled via the notary’s payment of the purchase price
- No sale – no commission
What does letting cost?
One month’s rent (net rent).
- Only due once the lease is signed
- Listings, viewings and credit checks included
- No tenant – no fees
What does the valuation cost?
Nothing. The on-site valuation is free and without obligation – afterwards you decide freely whether and with whom to sell.
What other costs arise when selling?
Besides the commission, in Basel-Country expect:
- Notary (purchase contract, notarisation): CHF 800 – 2,500 depending on effort, plus VAT
- Land registry fee: approx. CHF 300
- Transfer tax: 1.25 % for the seller (1.25 % for the buyer)
- Property gains tax: only if there is a gain, see ‘Taxes’
- Possibly cancellation of the mortgage note and early repayment penalty for a fixed-rate mortgage
Do I have to commit to a long contract?
No.
- Mandate with no upfront costs, duration and terms in writing
- A brokerage contract can be terminated at any time
- Commission only if the sale is concluded with a buyer we introduced
How does the sale work?
How does a house sale work?
In seven steps – we support you through each one:
- Free on-site valuation
- Mandate and documents
- Marketing: photos, documentation, listings
- Viewings and negotiation
- Reservation agreement + buyer’s financing confirmation
- Notarisation
- Land register entry and payout
How long does a sale take in Basel-Country?
With the right price 3 to 4 months:
- Marketing: 6–10 weeks
- Reservation and purchase contract: 2–3 weeks
- Notarisation and land register: 3–6 weeks
Too high a price prolongs everything.
Who draws up the purchase contract?
A notary in Basel-Country (independent, with state authorisation to notarise).
- Land purchases must be notarised – a private contract is void
- We provide the notary with all the details and documents
- We coordinate the appointment with both parties
What happens at the notary appointment?
The contract is signed and notarised.
- Seller and buyer sign before the notary
- The buyer presents an irrevocable payment undertaking from their bank
- The notary registers the transfer of ownership with the land registry in Arlesheim
When do I get the money?
After the land register entry – usually 2–4 weeks after notarisation.
- Part may be withheld by the notary until the property gains tax has been assessed
What is a reservation agreement?
A written declaration of intent between you and the buyer.
- Deposit usually 1–2 % of the purchase price
- Secures the phase up to the notary appointment
- Only the notarised purchase contract is legally binding; flat-rate contractual penalties are ineffective
When do benefits and risks transfer?
Usually with the land register entry or the agreed transfer of possession.
- From then on the buyer bears costs and risks
- Insurance, mortgage interest and running costs are settled as of the cut-off date
Can I sell my house while I still live in it?
Yes – that is the normal case.
- Viewings by arrangement
- Moving out and handover are set out in the purchase contract
- A later handover date is negotiable
Which documents do I need?
Which documents do I need for the sale?
For every property:
- Current land register extract
- Building insurance certificate (BGV)
- Floor and cadastral plans, building permits
- Running cost statements, existing mortgage notes
- For condominiums: deed of constitution, regulations, minutes, renovation fund
- For let properties: leases
Whatever is missing, we obtain for you.
Where do I get a land register extract?
From the Basel-Country land registry in Arlesheim – can be ordered online. As part of the mandate we take care of it for you.
Do I need an energy certificate (GEAK)?
In Basel-Country the GEAK for a sale is voluntary.
- Mandatory only in FR, VD, NE and JU
- For older houses it strengthens buyers’ confidence
- Cost approx. CHF 450 – 750
My oil heating is old – is that a problem when selling?
Since 1.1.2026 new rules apply in Basel-Country.
- A defective fossil-fuel heating system or a burner over 15 years old must be replaced with a renewable system
- Buyers factor in these costs
- We advise you on whether replacing it before the sale makes sense
What about the mortgage note?
It is dealt with in the purchase contract.
- Usually transferred to the buyer; a new issue costs CHF 350 – 1,500
- Your mortgage is repaid from the purchase price
- For fixed-rate mortgages: ask the bank about the early repayment penalty beforehand
What taxes do I pay?
What is property gains tax?
The tax on the gain on sale: sale price minus investment costs.
- Investment costs = purchase price + value-adding investments + commission + notary
- Basel-Country rate: 3 % to 25 %; from CHF 120,000 gain a flat rate 25 %
- Surcharge for ownership under 5 years, deduction for long owner-occupation (from the 21st year)
Can I avoid property gains tax?
Deferring, yes:
- Replacement purchase: buy another owner-occupied home in Switzerland within 2 years
- Inheritance and gifts: also deferred
- Documented investments reduce the gain – keep the invoices
What is the transfer tax?
A tax on the change of ownership: 1,25 % of the purchase price each for seller and buyer.
- Buyer exempt if they live in the property permanently
- Seller exempt if they invest the proceeds within 2 years in a replacement property with the same use
An example, please.
House bought in 2010 for CHF 700,000, sold in 2026 for CHF 1,000,000, without major investments:
- Gain after indexation, commission and notary: around CHF 240,000
- Property gains tax: around CHF 60,000
- Transfer tax seller: CHF 12,500
- With a replacement purchase: both deferred or exempt
We work out your specific case before the sale.
Do you also do tax returns for property owners?
Yes – Roman Frey, our financial adviser and property fiduciary, takes care of that.
- Imputed rental value, flat-rate or actual maintenance deductions
- Mortgage interest, energy-saving measures
- Let properties, property gains tax return
I have inherited – what now?
The inheritance itself does not trigger property gains tax (deferral).
- We value the property for the division of the estate
- We support the community of heirs neutrally
- Sale or takeover by one heir – both possible
Questions about letting.
How high can I set the rent?
In line with the market and without an excessive yield.
- Permissible net yield per the Federal Supreme Court: reference rate + 2 % (currently 1.25 % + 2 %)
- Tenants can challenge the initial rent within 30 days
- We calculate and document the rent
What is the reference interest rate?
The average mortgage rate published quarterly by the Confederation – as of September 2026: 1,25 %.
- Determines when rents may be lowered or raised
- Feeds into the calculation of the permissible rent
Is there a mandatory form for the initial rent in Basel-Country?
No. Unlike in Basel-City, Zurich or Bern, the previous rent does not have to be disclosed on an official form in Basel-Country. We still recommend transparency.
How do you vet the tenants?
With four documents:
- Debt enforcement register extract (no older than 3 months)
- Proof of salary or employer confirmation
- References from the previous landlord
- Proof of liability insurance
Rule of thumb: rent at most one third of net income.
How high can the rental deposit be?
At most three months’ rent (Art. 257e CO), in a blocked account in the tenant’s name.
What belongs in the lease?
The key points:
- Parties, property, start of tenancy
- Net rent and running costs (only what is expressly listed)
- Deposit, notice periods and dates
- House rules, handover report
We use vetted templates under the Swiss Code of Obligations.
Do you also let new builds off-plan?
Yes. We start the first letting several months before move-in.
- Visualisations and floor plans
- Rent calculation
- Viewings on the construction site
What is my property worth?
How is my property valued?
Depending on the property with the appropriate method – plus an on-site viewing.
- Hedonic: single-family houses and owner-occupied flats – comparison with thousands of transactions, as banks do
- Real value: special properties – land plus current building value
- Income value: apartment buildings and commercial
What is the difference between market value, tax value and insurance value?
Three values, three purposes:
- Market value: the price a buyer pays today – counts when selling
- Tax value: cantonal assessment basis, usually significantly lower
- Building insurance value: replacement value of the building, excluding land
What are current prices in Basel-Country?
Asking prices in Liestal and surroundings 2026:
- Single-family houses: around CHF 7,700 – 8,000 per m²
- Owner-occupied flats: around CHF 8,500 – 9,600 per m²
- Cantonal vacancy rate: 0.6 % – good properties are in demand
Should I renovate before selling?
Usually not much.
- Tidying, painting, tending the garden, fixing broken details – that brings more than expensive renovations
- You rarely recover renovation costs when selling
- At the valuation we tell you what is worthwhile
Questions about financing.
How much equity does a buyer need?
At least 20 % of the purchase price.
- Up to half (10 %) may come from the pension fund – early withdrawal or pledge
- The other 10 % must be ‘hard’ equity: savings, pillar 3a, advance inheritance, gift
- Affordability: housing costs at most one third of gross income (calculated with 5 % interest, 1 % maintenance, repayment)
That is why we ask buyers for a financing confirmation early on.
How high are mortgage rates in 2026?
Depending on term and bank:
- Fixed-rate mortgages: around 1.4 % to 2.1 %
- SARON mortgages: below that
The mortgage calculator on the Financial advice page shows you the monthly costs.
What happens to my current mortgage when I sell?
It is repaid from the purchase price.
- For fixed-rate mortgages the bank usually charges an early repayment penalty
- Ask for the amount early
- Alternative: the buyer takes over the mortgage
