Foundation Risk in Dutch Valuation Reports, What Amsterdam Buyers and Sellers Need to Know.

Since 1 April 2026, foundation risk has become a standard part of the Dutch valuation report. For buyers and sellers in Amsterdam, this is a major change.

In many parts of Amsterdam, foundations already played a role behind the scenes. Today, they directly affect valuations, mortgage approvals, negotiations and sometimes even the speed of a sale. At Burgemeester Vastgoed, foundation risk is now discussed earlier in the buying and selling process because waiting until the valuation stage can create delays and uncertainty.

What changed in the valuation report?

Dutch valuers now work with foundation risk classifications from A to E.

• Risk class A, low risk
• Risk class B, Limited Risk. 
• Risk class C, Increased awareness, this rarely causes issues. 
• Risk class D, High risk, the valuer will most likely request additional research (QuickScan).
• Risk class E, increased risk, Very high risk. Additional research will be needed.

The information is sourced from the database of the Dutch Knowledge Centre for Foundation Problems (KCAF) and is now included in the property valuation process. A higher classification does not automatically mean a property has structural damage. It does mean there may be reason for additional investigation or supporting documentation before the valuation can be completed. This is important because most mortgage lenders require an approved valuation report before financing is granted.

Why foundation risk matters more in Amsterdam

Amsterdam has one of the oldest housing stocks in the Netherlands. Many buildings are constructed on wooden foundation piles and some neighborhoods are more sensitive to subsidence and foundation movement than others. As a result, foundation risk appears more frequently in Amsterdam valuation reports than in many newer cities.

Valuers may assess factors such as:

• Construction year
• Location specific data
• Previous foundation reports
• Visible cracking
• Maintenance condition
• Municipal archive information
• Comparable buildings nearby
• VvE documentation for apartments

This means a postcode alone never tells the complete story. Two apartments in the same area can receive different assessments depending on the available data and condition of the building.

Can foundation risk delay a mortgage?

Yes.

If a valuation report includes a higher foundation risk classification, lenders may ask for extra documentation or further investigation before approving the mortgage. That can delay financing and create uncertainty during negotiations. NHG has also confirmed that the updated valuation report provides more detailed information regarding foundation risk and that this information is relevant when assessing mortgage applications.

For buyers in Amsterdam, preparation matters

In Amsterdam’s competitive property market, buyers often focus on location, square meters and asking price first. But foundation quality can have a direct impact on the long term value and future costs of a property.

Foundation condition may influence:

• Mortgage approval
• Future maintenance costs
• Resale value
• Negotiation strategy
• Long term investment potential

This is especially important in older apartment buildings where responsibility for maintenance may be shared through the VvE. For sellers, transparency is becoming more important. Sellers who prepare properly are often in a stronger position during negotiations. For older properties or homes in known risk areas, it is smart to organize documentation before listing the property on the market. Clear information creates confidence and helps reduce delays once the buyer starts the mortgage process.

Why local knowledge makes a difference

Foundation risk in Amsterdam is highly local. Conditions can vary per neighborhood, per street and sometimes even per building block. That is why local market knowledge matters. An experienced Amsterdam buying or selling agent understands which areas require additional attention and knows how to interpret foundation related information within the context of the local market. At Burgemeester Vastgoed, buyers and sellers are guided through the full process, including valuation risks, VvE documentation, negotiations and financing strategy.

More transparency in the market

The updated valuation report creates more transparency in the Dutch housing market. At the same time, it also increases the importance of preparation and proper guidance. For buyers, this means understanding the risks before committing to a purchase. For sellers, it means preparing documentation early and preventing surprises later in the process.
