What is a "home improvement mortgage"?
Do you want to renovate your home but aren’t sure how to approach it financially? Then it’s helpful to know what a renovation mortgage entails. A renovation mortgage isn’t a separate type of mortgage, but rather a way to borrow extra money through your existing mortgage or a second mortgage specifically for renovating your home. This allows you, for example, to finance a new kitchen, bathroom, or dormer window without immediately dipping into your savings.
In practice, a renovation mortgage works as an increase to your existing mortgage or as a second mortgage. With a private increase, you’ve already arranged for a higher registration with the notary when you took out your first mortgage, making it easier to borrow additional funds. If you opt for a second mortgage, you’ll take out a new loan on top of your current mortgage. In both cases, the lender will assess your income and the value of your home after the renovation.
But what exactly do you use a renovation mortgage for? Think of permanent improvements, such as an addition, a new bathroom, or the installation of solar panels. Sustainability measures, such as insulation or a heat pump, also fall under this category. In 2023, 1 in 6 homeowners used their mortgage for a renovation. This shows just how popular this form of financing is, especially now that sustainability is becoming increasingly important.
The construction account is an important part of the renovation mortgage. The amount you borrow for the renovation is set aside in a construction account. You can then easily submit invoices for the renovation. This gives you a clear overview and control over your expenses. Please note: You can only obtain a renovation mortgage if you have equity in your home. This means the home must be worth more than your current mortgage balance after the renovation. Lenders always assess your income and the (future) home value before approving the loan. Good news if you want to make your home more sustainable: for energy-saving measures, you can borrow up to 106% of the home’s value.

Financing Options for Your Renovation
Are you about to upgrade your home and wondering what the smartest way is to finance it? There are several options for arranging a renovation mortgage, each with its own advantages, considerations, and costs. Below, we’ve clearly listed the most important options for you.
Increasing Your Mortgage or Taking Out a Second Mortgage
The most common way to finance a renovation is to increase your existing mortgage or take out a second mortgage. If you arranged for a higher loan-to-value ratio with the notary when you purchased your home, you can often borrow additional funds relatively easily. Otherwise, you’ll need to take out a second mortgage, which usually requires a notary and a new appraisal report.
Pay close attention to the terms and conditions. The bank will consider your income, the value of your home after the renovation, and your existing mortgage balance. Be sure to factor in additional costs, such as notary fees, advisory fees, and an appraisal. For example: you increase your mortgage by €30,000 to pay for a new kitchen and an addition. This allows you to spread the costs over a longer period and often benefit from a lower interest rate than you would with a personal loan.
Using Home Equity
Has your home increased in value beyond your current mortgage balance? If so, you can use that equity toward your renovation mortgage. Equity is the difference between your home’s market value and the outstanding mortgage balance. Due to rising home prices, Dutch homeowners had an average of €70,000 in equity in 2024.

The bank will reassess your income and the (expected) value of your home after the renovation. Taking out a loan against home equity is especially attractive if your renovation further increases the home’s value.
Personal Loan or Consumer Credit
For smaller renovations, such as a new floor or bathroom up to €25,000, a personal loan or consumer credit is an option. The interest rate is usually higher than with a renovation mortgage, but you don’t have to pay notary fees and the money is deposited into your account quickly.
Please note: the term is shorter, and the monthly payments are often higher. An additional advantage is that with a personal loan, you may sometimes be able to deduct the interest if you can demonstrate that you spent the money on your home and repay the loan within 30 years. Still, this option remains best suited for relatively small projects.
Using Savings
Do you have savings available? If so, you can choose to finance (part of) the renovation with them. The biggest advantage is that you pay no interest and have no additional monthly payments. You also don’t need to submit any paperwork or get approval from the bank.
The downside is that your savings buffer will shrink. Financial advisors recommend always keeping at least three to six months’ worth of fixed expenses as a reserve. Keep in mind that, starting in 2026, you’ll pay tax on savings exceeding €59,357 per person.
Financing Energy-Saving Measures
Do you want to make your home more sustainable, for example with solar panels, insulation, or a heat pump? If so, with a renovation mortgage, you can borrow up to 106% of the home’s value if you spend this additional amount entirely on energy-saving measures. This makes it attractive to invest directly in lowering your energy bill.
There are also various grants and special loans available for sustainability improvements. Here’s a real-life example: you borrow an additional €15,000 for HR++ glass and a heat pump. This makes investing in sustainability both feasible and affordable.
Step-by-Step Guide: How to Apply for a Renovation Mortgage
Are you about to upgrade your home and want to know how to apply for a renovation mortgage? With this step-by-step guide, we’ll walk you through the entire process, from the initial idea to opening the construction account. That way, you’ll know exactly what to expect and what to look out for.
Step 1: Research and Planning
Start by clarifying your renovation plans. What exactly do you want to change about your home? Estimate the costs and create a realistic budget. Consider items such as materials, labor, and a contingency fund for unexpected expenses. Next, have your home appraised—both its current value and its future value after the renovation. This will immediately show you how much room there is for a renovation mortgage. Also check with your notary to see if a higher mortgage registration is already possible.
Step 2: Calculate Mortgage Options
Now you’ll determine the maximum amount you can borrow. Use online calculators or consult an independent advisor to calculate your maximum renovation mortgage. This process takes into account your income, the value of your home, and your home equity. Take current lending standards and eligibility requirements into account. This way, you’ll know exactly whether your plans are feasible and won’t run into any surprises.
Step 3: Request and compare quotes
Request quotes for your renovation mortgage from various lenders. Pay close attention to the interest rates, terms, and the maximum loan amount. The difference in interest rates can be significant—sometimes as much as 0.5% per year. Also compare the flexibility of the construction account and the options for penalty-free prepayments. A smart comparison can save you thousands of euros over the entire term.
Step 4: Submit Your Application and Gather Documents
Have you made your choice? Then it’s time to submit your application for the renovation mortgage. Gather all the necessary documents, such as the appraisal report, income information, and a breakdown of the renovation costs. Want to know exactly what you need to submit? Check out the overview of required documents for a renovation mortgage. Submit everything to the lender and follow the application process closely. Be sure to respond promptly to requests for additional information.
Step 5: Finalize the Mortgage and Open a Construction Account
Once your renovation mortgage is approved, you’ll go to the notary to finalize everything officially. The additional funding for your renovation will be deposited into a construction account. From this account, you can easily submit invoices from contractors and suppliers for reimbursement.
Keep track of everything by keeping neat records of all your expenses. This way, you’ll always have the renovation and its financing under control.
Advantages and Pitfalls of a Renovation Mortgage
Are you about to renovate your home and considering a renovation mortgage? If so, it’s wise to not only look at the benefits but also to be fully aware of the pitfalls. This way, you can avoid surprises and make an informed decision that’s right for your situation.
Advantages
A home improvement mortgage offers quite a few advantages if you’re planning to renovate your home. First of all, you’ll benefit from a much lower interest rate than with a personal loan or consumer credit. This immediately reduces your monthly payments.
In addition, the interest on a home improvement mortgage is often tax-deductible if you choose an annuity or linear mortgage. This allows you to claim a tax benefit, as long as the money goes toward home improvements.
Another advantage: you spread the costs over a longer term—sometimes as long as thirty years. This keeps your monthly payments manageable. This is particularly attractive for major renovations, such as an addition or a dormer window.
Do you have equity in your home? If so, you can use it to benefit from rising home prices. Often, the renovation itself also increases the property’s value, especially when it involves making the home more sustainable or adding an extension.
The construction loan account provides clarity. You know exactly what you’re borrowing for and have control over how the funds are spent. This means you’re less likely to face financial surprises with a renovation mortgage.
Pitfalls
However, a renovation mortgage also has its pitfalls. Your monthly payments will increase, and if your home’s value drops, you run the risk of ending up with residual debt. Additional costs, such as notary fees, appraisals, and consulting fees, are often added to the bill . Not every renovation automatically increases the home’s value. Take a new kitchen, for example: it’s nice for you, but it’s not always an investment that pays off when you sell. This means you could end up borrowing too much without realizing it and be left with a higher debt. The tax rules are strict. Interest deductions are only allowed for annuity or linear renovation mortgages, provided the funds are used for home improvements. If you spend the money on something else, this benefit is forfeited. The income and borrowing criteria are also strict. You must be able to demonstrate that you can handle the payments, especially when refinancing or taking out a second mortgage.

Finally, if your renovation ends up costing more than planned, you’ll usually have to pay the difference out of pocket. Thorough preparation and a realistic estimate are therefore essential when taking out a renovation mortgage.
Smart Financing: Tips and Considerations for 2026
Do you want to make smart use of a home improvement mortgage in 2026? These practical tips will help you make the right choices and avoid surprises. That way, you’ll get the most out of your renovation and your finances.
- Create a realistic renovation plan and budget
List all the cost items for your renovation: materials, labor, and unforeseen expenses. Always set aside an extra 10 to 15 percent for unexpected costs. Use handy tools to calculateyour maximum mortgage amount, so you know how much you can responsibly borrow with a renovation mortgage. - Understand the tax rules and benefits
Keep in mind that mortgage interest is only tax-deductible with an annuity or linear renovation mortgage—and only if you spend the money on home improvements. Check for current government subsidies for sustainability measures, as tax benefits can make a significant difference in your monthly payments. - Compare lenders and terms
Don’t just automatically go with your current bank. Compare different lenders based on interest rates, terms, penalty-free prepayment options, and the flexibility of the construction loan account. The lending standards for 2026 could positively impact your maximum home renovation mortgage amount due to expected wage increases. - Consider future plans
Do you expect to renovate again or perhaps move? If so, opt for flexibility in your renovation mortgage so you aren’t unnecessarily tied to strict terms or high costs when making changes. - Keep your financial buffer in mind
Make sure you always have a financial reserve left over after taking out a renovation mortgage. A good rule of thumb: set aside at least three to six months’ worth of fixed expenses as a buffer, so you don’t run into trouble in unexpected situations. - Seek advice from an independent mortgage advisor early on
Avoid mistakes and disappointments by seeking advice early on. An independent advisor will objectively assess your situation and help ensure you don’t overpay or miss out on important tax benefits with your renovation mortgage. - Pay attention to the term and repayment method
Choose a repayment method that suits your needs and financial situation. Think carefully about the term: a longer term means lower monthly payments, but ultimately more interest on your home improvement mortgage.
By keeping these points in mind, you’ll be able to make informed choices in 2026. This way, you’ll get the most out of your home improvement mortgage and maintain control over your financial future.

3. Can I finance my renovation when buying a home?

6. Can I get a renovation mortgage without equity?
Without home equity, you can only get a renovation mortgage if the appraiser determines that the value of your home will demonstrably increase after the renovation. This is always assessed by the lender. Want to know what rules will apply in 2026? Read “What’s Changing for Your Mortgage in 2026?” for the latest developments.
