7 Surprising Costs to Expect in 2026

Are you planning to buy a home in 2026? Then it probably won’t surprise you that the costs of buying a home have risen significantly. What many people don’t realize is that, in addition to the purchase price, there are a surprising number of extra costs coming your way. Below are the seven most unexpected expenses you really need to factor in. This will help you avoid financial setbacks and ensure you’re fully prepared to make your dream home a reality.

1. Mandatory sustainability measures and energy label upgrades

Starting in 2026, every home must have at least an energy efficiency rating of C. This requirement means that many homebuyers will have to invest immediately in insulation, HR++ glass, a heat pump, or solar panels. As a result, the costs of buying a home can quickly add up. On average, an energy label upgrade will cost you over €7,500, but for older homes, this can even rise to €10,000.

It’s not just the investment itself that counts, but also additional costs for consulting and inspection. Subsidies are available, but coverage is decreasing as more and more people make their homes more sustainable. Did you know that failing to meet these requirements makes it harder to get a mortgage?

Making your home more sustainable increases its value, but it does require a substantial financial buffer when factoring in the costs of buying a home.

2. Higher transfer tax for second homes and investors

Are you buying a second home or investing as a real estate investor? If so, you’ll be in for a shock in 2026 when the transfer tax rises sharply. It will increase to 8 percent for properties not occupied by the owner. As a result, the costs of buying a home will be significantly higher for investors and parents buying for their children.

For example: for a home priced at €400,000, you’ll pay €32,000 in transfer tax. First-time homebuyers still benefit from an exemption, but the conditions are stricter. Age limits and a price cap make it harder to qualify for this exemption.

This measure is intended to make the housing market more accessible to first-time homebuyers, but at the same time increases the costs of buying a home as an investment. Take this cost into account and check carefully whether you qualify for an exemption. That way, you won’t face any surprises when calculating the total costs of buying a home.

3. Increased Costs for Structural Inspections

A structural inspection will be mandatory for many homes in 2026, especially if there is overdue maintenance or the property is older. Due to stricter reporting requirements, rates have risen to an average of €600 to €800. This is a significant increase compared to a few years ago. As a result, the costs of buying a home are increasing.

Reports must comply with new NEN standards. Special attention is given to foundations, asbestos, and sustainability. For historic buildings or homes outside the Randstad, the costs may be even higher.

Don’t be caught off guard—schedule a structural inspection well in advance. That way, you’ll know exactly where you stand and can better estimate the costs of buying a home.

4. Mandatory digital appraisal and validation

Starting in 2026, banks will require a validated digital appraisal with a 3D scan. The cost ranges from €450 to €700, depending on the location and complexity of the home. This makes the upfront costs of buying a home less predictable.

The advantage is that the appraisal is faster and more objective. The disadvantage is that there is less room for negotiation. Some providers charge extra for a physical inspection in addition to the digital scan. Furthermore, these appraisal costs are no longer always tax-deductible.

Pay close attention to your mortgage lender’s terms and conditions. Always request a quote in advance so you don’t face unexpected costs. This way, you can keep the total costs of buying a home under control.

5. Bank Guarantee and Higher Security Deposit

In 2026, the security deposit will generally remain at 10 percent of the purchase price, especially in popular regions where competition is high. If you can’t pay this amount yourself right away, you’ll need to arrange a bank guarantee through a bank or insurer. This will cost you 1 to 1.5 percent of the guarantee amount.

Example calculation: for a home priced at €500,000, you’ll pay €500 to €750 in fees for the bank guarantee. This is in addition to the regular home-buying costs. Buying property or doing business internationally? In those cases, the requirements are often even stricter.

Make sure you arrange the security deposit and guarantee on time. Failure to pay on time can result in penalty clauses in the purchase contract. So be sure to factor these home-buying costs into your budget well in advance.

6. Mortgage advisory and brokerage fees are rising

Mortgage advisory fees are expected to rise to an average of €2,800 to €3,500 by 2026. This is due to stricter regulations and increased administrative requirements. Independent advice is becoming increasingly important, as the mortgage market is more complex than ever. This is driving up the costs of buying a home.

For business owners and self-employed individuals, there are additional costs, such as an income statement, which can cost up to €500. Digital providers are sometimes cheaper but offer less personalized guidance. Rates vary significantly by region and advisory firm.

Always compare multiple providers before making a decision. This way, you’ll get the best advice for your situation and keep the costs of buying a home as low as possible.

7. Costs for the digital deed of sale and notary processing

Since 2026, the digital deed of sale has been the standard. This entails additional validation costs. Notary fees are rising due to stricter identification and anti-money laundering rules. On average, you’ll pay between €1,200 and €1,700 for the transfer of ownership and the mortgage deed combined.

Some notaries charge a surcharge for digital signatures or expedited processing. International clients often pay more. Be sure to factor these items into your calculation of home-buying costs.

Please note: not all notary fees are tax-deductible. Always request a detailed quote in advance. This will help you avoid surprises when finalizing your purchase.
