Do I need my own property valuation as a buyer?

In most cases no. Every bank values the property itself before granting a mortgage, usually with a hedonic model, at no cost to you. A paid appraisal of your own is worthwhile mainly for special properties, for inheritance divisions and divorces where a neutral value is needed between the parties, or when you are the one selling.

What happens if the bank's valuation is below the purchase price?

The bank finances on the lower of the two values, following the lowest-value principle. If its estimate is below the purchase price, you must cover the entire difference with additional equity, and the hard 10 per cent is calculated on the valuation. That is exactly why it pays to have the financing checked before you bid, not after.

What are free online valuations worth?

For standard properties in well-documented locations, hedonic online estimates are a usable plausibility check, with a range of easily plus or minus 10 per cent. For special cases such as converted farmhouses, one-of-a-kind homes or building leases the models fail, because comparison data is missing. Take them as a rough second opinion, not as the truth.

Does a new kitchen increase the property's value?

By less than it cost. Fit-out standard affects value, but the market rarely pays the full CHF 50'000 more for a CHF 50'000 kitchen, because taste is personal and kitchens age quickly. Location, by contrast, is fully priced in, because it cannot be replaced.

Property valuation: when you need one and when you don't

Portals and advisers sell property valuations as if they were compulsory for buyers. The truth is less spectacular: the bank values the property anyway, free of charge and before it lends you a single franc. Where a valuation really counts, and where your money is better spent.

The bank values it anyway

No Swiss bank grants a mortgage without its own valuation. For standard residential property this runs through hedonic models: the property is compared with thousands of actual sales of similar homes, by location, floor area, year built and condition. You get the result in the financing meeting, it costs you nothing, and it is the only valuation that counts for your financing. An additionally purchased appraisal changes nothing about the bank's estimate.

Where the valuation still catches you

The bank's valuation becomes relevant for you in one case: when it is below the purchase price. The bank finances on the lower value under the lowest-value principle, and you pay the difference entirely out of your own pocket. Bid above market value in a bidding process and you find out at the worst possible moment. So: have the financing checked, property included, before the bid, not after the handshake.

When a paid appraisal is worth it

→Inheritance division and divorce: when parties have to agree on a value, it takes a neutral estimate rather than numbers poker. More in the article Inherited a property.
→Special properties: converted farmhouses, one-of-a-kind homes, building leases, multi-family houses. Hedonic models lack the comparison data here, and often the bank itself requires an individual appraisal.
→Selling: whoever sets the asking price wants to know what the market will bear. Set it too high and it costs months; too low and it costs money.
→Doubts about the price: if your gut feeling and the listing are far apart, an estimate is cheaper than a bad purchase. First step: a free online valuation as a plausibility check.

Location beats fit-out

In every valuation, model or expert, the location factors dominate: municipality, tax multiplier, transport links, view, noise. The fit-out has a weaker effect, and it works asymmetrically: a new kitchen for CHF 50'000 rarely lifts the value by CHF 50'000, because the market doesn't pay full price for taste and fit-out ages. A location advantage doesn't age. In practice, when comparing two properties: don't be dazzled by freshly renovated surfaces, and weight the location difference more heavily than the fit-out difference. How to read locations is covered in the article How to spot a good location.

What you really need as a buyer

Not the property's value to the nearest thousand francs, but two other numbers: what the bank will carry, and where your personal limit lies. The first is settled in the financing meeting. The second comes from your income and your equity, not from the property, and it protects you where no valuation helps: at the moment someone bids more and you have to decide whether to go along.

Frequently asked questions

The buying check doesn't value the property; it runs your side of the numbers: affordability, equity and your personal price limit for the negotiation.
