Definition of property pledging and mortgage lending value in Switzerland

Pledging means providing an asset as security for a loan, without necessarily selling it or transferring it permanently. In the context of a Swiss mortgage, it can allow financial or pension assets to be used as additional security for the lender.

Pledging definition: what it means in practice

In a mortgage transaction, pledging does not replace the mortgage registered on the property. It is more often added to the main property security when the bank wants to secure the financing further or when the borrower wants to avoid liquidating certain assets.

In practical terms, you can pledge securities, a bank account, a life insurance policy, a pillar 3a account or, in some cases, pension assets. These assets generally remain in your name, but they are blocked or assigned in favour of the lender. If you fail to meet your repayment obligations, the bank can enforce its rights over the pledged asset under the agreed conditions.

The important distinction is this: pledging an asset does not always mean giving it up economically. You may keep ownership of the asset, but you lose part of your freedom to use it for as long as the pledge remains in place.

Property pledging: definition and difference from a mortgage

The expression “property pledging” is often used imprecisely. Technically, in Swiss property financing, the main security is generally a real estate pledge, often in the form of a mortgage certificate. Pledging, by contrast, usually concerns an asset that is separate from the property being purchased: an account, a securities portfolio, an insurance policy, pillar 3a assets or another item of wealth.

The difference is therefore essential. The mortgage is secured by the financed property. Pledging concerns another asset that you provide as additional collateral.

Example: you buy a home in Switzerland, but you do not want to withdraw your pillar 3a to increase your equity. Depending on your situation, the bank may accept this pillar 3a being pledged. It remains invested or held within its pension structure, but it serves as security for the financing. This solution can be attractive from a tax and wealth-planning perspective, but it reduces your future room for manoeuvre.

Why does a bank ask for pledged assets?

A bank may ask for pledged assets when the application presents a higher risk than average or when the financing structure requires additional security. This can happen if the loan-to-value ratio is high, if income is irregular, if part of the equity comes from illiquid assets or if the borrower wants to keep certain investments instead of selling them.

Pledging can also be used to optimise a financing strategy. For example, instead of selling securities in an unfavourable market environment, you may sometimes be able to keep and pledge them. This avoids a forced sale, but it creates another risk: if the value of the securities falls sharply, the bank may require additional collateral or a reduction in exposure.

This is a point many borrowers underestimate. Pledging is not a free solution or a neutral one. It can improve the feasibility of a financing arrangement, but it creates a dependency between your mortgage and the value of the pledged asset.

Mortgage lending value: definition and calculation by the lender

In Swiss mortgage financing, the mortgage lending value is the property value used by the lender as the basis for determining the loan-to-value ratio and the maximum mortgage amount. It does not therefore automatically correspond to the seller’s asking price, the purchase price or the owner’s personal estimate. It is a value established by the lender for financing and risk-management purposes. As a general rule, it may not exceed the property’s market value.

This concept must be distinguished from the value assigned to other assets that may be provided as additional security. When a securities portfolio, life insurance policy or pension assets are used as collateral through property pledging, the lender separately determines what proportion of those assets it is prepared to recognise as security. The mortgage lending value of the property, by contrast, relates to the home, investment property or plot of land secured by the mortgage lien.

To calculate the mortgage lending value of an owner-occupied home, the lender generally begins by estimating its market value. For relatively standard apartments and houses, it may use a hedonic valuation method. This method compares the property with completed transactions involving similar properties and takes into account factors such as the municipality, neighbourhood, living area, plot size, age and condition of the building, standard of fittings and other specific characteristics. A physical inspection is not always required when the lender has access to recent and sufficiently documented data. An individual valuation and inspection may, however, be required for an unusual property that is difficult to compare or sell.

A different method is generally used for an investment property. In this case, the mortgage lending value is determined primarily on the basis of the income value. The lender estimates the sustainable net rental income and capitalises it using a rate that takes account of management and maintenance costs, future investment requirements, vacancy risk, the property’s location and regional economic conditions. Temporarily high rents or income that is not considered sustainable may therefore not be taken fully into account.

The lender also applies a prudent approach. It should not include a hypothetical future increase in the property’s value or rely solely on the expectations of the seller or buyer. It also considers risks specific to the property, including its condition, use, marketability, location and any legal restrictions. Each lender defines its valuation methods in its internal policies. Consequently, two lenders may determine slightly different mortgage lending values for the same property.

When a property is purchased, the lower-value principle generally applies. The mortgage lending value is therefore the lower of the purchase price and the market value estimated by the lender. If you purchase a home for CHF 1,000,000 but the lender estimates its market value at CHF 900,000, the mortgage lending value will be CHF 900,000. Conversely, if the lender values the property at CHF 1,050,000 while the purchase price is CHF 1,000,000, the mortgage lending value will normally be limited to CHF 1,000,000. Exceptions may apply, particularly to certain transfers at preferential prices between related parties.

This difference directly affects the amount of equity you must contribute. In the first example, if the lender accepts a maximum loan-to-value ratio of 80%, the maximum mortgage calculated on a mortgage lending value of CHF 900,000 is CHF 720,000. You must therefore finance the remaining CHF 280,000 yourself, in addition to any acquisition costs that are not covered by the mortgage. The difference between the price paid and the mortgage lending value cannot simply be financed through a proportional increase in the mortgage loan.

The calculation can be summarised as follows:

Maximum mortgage amount = mortgage lending value × accepted loan-to-value ratio

This result does not, however, constitute a financing commitment. The lender also assesses your affordability, income, other debts, the overall quality of your application and any additional security available. Even when the mortgage lending value theoretically permits a certain loan amount, the lender may grant a smaller mortgage if it considers the resulting costs to be unaffordable over the long term.

Finally, the mortgage lending value is not necessarily fixed permanently. The lender determines the frequency of reassessments according to the type of property, the level of indebtedness and market conditions. If an adverse development or exceptional event causes a lasting reduction in the property’s value, the lender may revise the mortgage lending value downwards. If the mortgage debt remains unchanged, the loan-to-value ratio will consequently increase. The lender may then require additional amortisation or further collateral.

Advantages and limits of pledging for your mortgage

The main advantage of pledging is that it allows you to use your wealth as security without having to liquidate it immediately. This can be relevant if you want to keep a securities portfolio, preserve a pension strategy or avoid a tax-inefficient withdrawal.

In the case of pillar 3a, for example, pledging can help strengthen the mortgage application while keeping the assets within the pension wrapper. This approach may be more consistent than a withdrawal if you want to preserve your retirement capital or avoid a poorly planned early withdrawal.

But the limit is clear: a pledged asset is no longer fully available. You cannot always move it, withdraw it or modify it freely. In addition, if the asset loses value, the bank may reassess its view of the risk. Pledging must therefore be analysed not only as security, but also as a constraint on your wealth.

When is pledging relevant?

Pledging can be relevant if you have solid assets but do not want to use them directly as equity. It can also be useful when you want to structure more flexible financing, avoid selling assets at the wrong time or preserve a long-term pension strategy.

However, it is less suitable if your financial situation is already tight. Pledging an asset does not make a loan more affordable. It can improve the security given to the bank, but it does not automatically reduce your charges, your interest or the risk of over-indebtedness. Before accepting a pledge, you should therefore check its real impact on your budget, your tax position and your wealth flexibility.
