If you want to buy or build a property, you are making one of the most important financial decisions in your life. In addition to choosing the right property, financing plays a key role – and in particular the question of what interest rate to finance at. This is because the interest rate not only influences the monthly burden, but also the total costs over decades.
Whether a new build, existing property or capital investment: the right strategy always depends on the current market situation – and on how well you prepare your own project. Solid financing does not start with the bank, but with well thought-out planning.
This is exactly where VIAREALIS® supports you – with comprehensive market knowledge, a strong network of financing partners and advice that goes far beyond standard offers.
The most important facts in brief
- Interest rates determine your financing costs – Even small differences in the interest rate have a significant impact on the monthly installment and total costs in the long term.
- Effective interest rate beats borrowing rate – When comparing offers, it is not only the stated interest rate that counts, but also the effective annual interest rate including all additional costs.
- Equity capital creates advantages – those who contribute more of their own capital benefit from better conditions and more financial security.
- Early planning pays off – Whether initial financing or a follow-up loan: if you act in good time, you can secure interest rates and gain room for maneuver.
Current interest rate level in 2025
If you want to buy or build a property today, you should keep an eye on the current interest rates – this is crucial for the sustainability of a mortgage and the monthly installment. In June 2025, the average borrowing rate for ten-year loans is 3.23% (source: https://www.baufi24.de/bauzinsen, as at June 2025)
Dr. Klein quotes a corridor of 3.09 % to 3.93 % (source: https://www.drklein.de/zinsentwicklung-prognose, as of June 2025), while Finanztip quotes 3.50 % to 3.70 % (source: https://www.finanztip.de/baufinanzierung/hypothekenzinsen, as of June 2025) for mortgages of 80 %. A closer look at the interest rate structure – including the borrowing rate and APR – helps to avoid additional costs.
For borrowers, this means that anyone planning to take out a loan today is operating in a market environment that is still affordable but challenging. The difference between the cheapest and most expensive offers is noticeable – so a comparison of conditions pays off more than ever. VIAREALIS® helps you to assess whether financing makes sense today – and shows you possible interest rate reserves with alternatives such as KfW subsidized loans or longer commitment periods.
VIAREALIS® thus pursues a holistic consulting approach: with in-depth market knowledge in Dresden, systematic comparison and a customized financing concept for your dream property – whether new construction or capital investment.
Debit interest vs. effective annual interest rate – why the difference matters
When banks quote an interest rate, they often talk about the borrowing rate – i.e. the pure price for the money borrowed. But this is only half the truth. The actual relevant value is the effective annual interest rate. In addition to the borrowing rate, it also includes all additional costs, such as processing fees, brokerage costs or commitment interest. According to the consumer advice center and legal requirements (§ 6a PAngV), the effective interest rate must always be stated – it allows you to make a realistic comparison between offers. VIAREALIS® works with you to ensure transparent contract terms and makes sure that you fully understand the interest rate structure before you make a decision.
Sample calculation – The rented property as an investment
Model scenario for Dresden, June 2025:
- Purchase price: € 300,000
- Equity (incl. ancillary costs):80.000 €
- Financing volume: € 220,000
- Debit interest rate (10 years): 3.23% (source: https://www.baufi24.de/bauzinsen, as at June 2025)
- Effective annual interest rate: approx. 3.35 %
- Repayment: 2 % annually
- Monthly installment (annuity ≈ 5.23%): approx. 958 €
Rent & yield:
- Monthly rent: € 900 → Annual rent: € 10,800
- Gross rental yield: € 10,800 / € 300,000 = 3.6 %
- According to Miet-Check Dresden, the average gross rental yield in Dresden is 4.26 % (source: https://www.drklein.de/zinsentwicklung-prognose as of June 2025)
- Deduction of maintenance and ancillary costs (e.g. € 2,800/year): Net rental yield ≈ 2.78 %
Financing in comparison: effective interest rate of 3.35 % vs. Net rental yield of 2.78 % → slight discrepancy. However, the total return remains attractive due to the leverage effect: as long as the net yield does not significantly exceed the interest rate level, owners benefit from value appreciation and rental growth in the long term. Calculate rental yield here
This model shows that even with a moderate rent, a rented property in Dresden can be a worthwhile capital investment thanks to interest, repayment and value development factors – with clever planning by VIAREALIS®.
Why only a sample calculation?
When it comes to financing, there is rarely an “off-the-peg” solution. Property location, credit profile, income situation, subsidy options, repayment requirements – all of these factors influence your monthly installment and long-term total costs. Instead of confusing you with ten different models, a realistic example calculation shows how interest, repayment and property interact. It provides orientation and creates a sense of scale.
VIAREALIS® advises you individually and, together with selected financing partners, creates a personal financing concept that is tailored to your project, your life situation and your goals. Because in the end, it’s not the model calculation that counts – but the solution that really suits you.
Fixed interest rates – security vs. flexibility
An important component of any construction financing is the question of the fixed interest rate. It determines how long you fix the agreed interest rate – usually for 10, 15 or even 20 years.
- Short-term commitments (e.g. 10 years) offer more flexibility, but also the risk of rising interest rates on follow-up financing.
- Longer commitments (15 years or more) create planning security, but often cost a little more – because banks factor in the interest rate risk.
Which term makes sense for you depends largely on your personal situation: Do you want to sell soon, rent out or use the property yourself in the long term? Together with the VIAREALIS® financing experts, you will develop a concept that takes into account both your financial possibilities and your future plans.
Forward loan – secure interest for tomorrow today
A forward loan is a special form of follow-up financing: you agree today on an interest rate for a loan that you will only draw down in one, two or even three years’ time. This is particularly interesting if your current fixed interest rate ends soon – and you want to secure the current interest rate level.
Typically, a forward loan comes with a small interest premium (e.g. 0.3 to 0.6 percentage points, as of June 2025), but offers maximum calculation security. Especially in uncertain market phases – such as at present – it can make sense to “reserve” favorable interest rates at an early stage.
Repayment strategies & monthly installment – the right mix for you
The repayment – i.e. the repayment of your loan – has a significant influence on how long you are financially tied and how high your monthly installment will be. An initial repayment of 2 % per year is standard. But there is room for maneuver:
- A higher repayment rate (e.g. 3% or more) means that you will be debt-free more quickly, but your monthly repayments will also be higher.
- Lower repayments give you more financial leeway in everyday life, but extend the repayment period.
A well thought-out repayment concept takes into account your life planning, such as starting a family, changing careers or retirement provision. With VIAREALIS®, you can develop a suitable strategy – including options such as special repayments, a change of repayment rate or a combination of annuity and building society savings.
Equity – your lever for better conditions
The more equity you contribute, the more favorable your financing will be. Why? Because banks rate the risk lower if you are financially involved yourself.
- 20% equity is considered a good minimum – e.g. to cover incidental purchase costs (land transfer tax, notary, estate agent).
- 30 % or more often opens up access to particularly good interest conditions and expands your scope for action.
Equity also reduces the loan amount – and therefore your monthly installment. VIAREALIS® helps you to calculate the optimal use of equity – and shows you ways in which, for example, your own contributions, existing reserves or subsidies can be used.
Provider comparison – where you can really save
Not every bank offers the same conditions. There are noticeable differences between regional savings banks, large commercial banks, direct banks and independent brokers – both in terms of interest rates and flexibility.
- Savings banks and cooperative banks score points with their regional proximity and personal service, but often have a conservative lending policy.
- Direct banks often offer more favorable interest rates – but with standardized processing.
- Brokers & platforms (such as VIAREALIS®) access several offers at the same time and can thus put together the best package for your situation.
A professional comparison often saves not only tenths of a percent, but also fees, time and nerves.
Don’t forget ancillary costs – what really adds to the purchase price
Many buyers only calculate the purchase price of the property – and forget the additional costs that need to be financed or covered with equity. Depending on the federal state and property type, these can account for up to 12% of thepurchase price.
Typical items:
- Real estate transfer tax in Saxony: currently 3.5%
- Notary and land registry costs: approx. 1.5-2 %
- Brokerage commission: up to 3.57 % (depending on agreement)
- Fees for expert opinions, energy performance certificates or financing brokerage
These costs are usually not covered by the bank loan – unless you choose 110% financing (with a premium). VIAREALIS® helps you to list all costs transparently and integrate them into your financial planning. In this way, you avoid unpleasant surprises – and secure your project from the outset.
Real estate financing vs. construction financing – what’s the difference?
These terms are often used interchangeably – but there are differences:
- Construction financing usually refers to the financing of new buildings or major modernizations – often with special construction loans, commitment interest rates and phased plans.
- Real estate financing covers all types of real estate acquisition – whether new construction, the purchase of an existing property or the financing of a capital investment.
It is important to note that both forms of financing require different strategies – especially when it comes to term, repayment and subsidy programs.
Take the first step now
Let us advise you personally on your investment in Dresden.
Commitment interest – the silent cost driver
For new construction projects in particular, it can take months before the loan is fully drawn down. But be careful: from a certain point in time (usually after 6 or 12 months), many banks charge so-called commitment interest – a kind of “penalty interest” on loan amounts that have not yet been drawn down.
These often amount to 0.25 % per month on the outstanding amount – that is an additional 3 % per year. If a loan of over €200,000 is delayed, this can quickly add up to several thousand euros.nancing vs. construction financing – what’s the difference?
These terms are often used interchangeably – but there are differences:
- Construction financing usually refers to the financing of new buildings or major modernizations – often with special construction loans, commitment interest rates and phased plans.
- Real estate financing covers all types of real estate acquisition – whether new construction, the purchase of an existing property or the financing of a capital investment.
It is important to note that both forms of financing require different strategies – especially when it comes to term, repayment and subsidy programs.
Follow-up financing – act in good time, plan wisely
Many borrowers initially focus on getting started with their financing. However, the exit is at least as important – or more precisely, the follow-up financing after the fixed interest rate has expired. Because what is well calculated today can become significantly more expensive in ten or fifteen years’ time.
For example, if your fixed interest rate expires in 2027, you can secure your follow-up conditions now – up to 60 months in advance – with a forward loan. This is particularly useful in times of rising interest rates.
Dresden real estate market – stable values, good opportunities
Dresden is considered one of the most dynamic real estate locations in eastern Germany – with a solid economy, high quality of life and continued influx. The market will remain stable in 2025:
- Good demand in city center locations, Radebeul, Striesen and Plauen
- New-build projects with moderate prices per square meter compared to major cities such as Leipzig, Berlin or Hamburg
- Rental yields of between 3-4 % are realistic depending on the location
These conditions make Dresden attractive for owner-occupiers and investors alike. VIAREALIS® knows the local market conditions inside out – and helps you not only to find offers, but also to classify and evaluate them correctly. This makes your financing not only affordable, but also future-proof.
Apartment or house? Make clever use of interest rate differences
Whether you are financing a condominium or a single-family home also makes a difference to the interest conditions. Why?
- Apartments are considered more stable in value and easier to utilize
- The risk for banks is lower → slight interest rate advantages (0.1-0.2 % possible)
- For rented apartments, the achievable yield also counts
For owner-occupiers, on the other hand, houses often offer more design freedom – but also more responsibility for maintenance and ancillary costs. VIAREALIS® advises you individually on which type of property suits your living situation – and how you can get the most out of your financing partner.
Compare interest rates – what really counts
Many people only compare the borrowing rate when buying a property – a mistake. The decisive criterion is the effective annual interest rate. It includes all additional costs: processing fees, commitment interest, brokerage costs and special conditions.
An offer with a 3.1% borrowing rate can be more expensive than one with 3.3% – if it contains hidden additional costs. Therefore, always pay attention to this when making a comparison:
- Effective interest rate (incl. all ancillary costs)
- Special repayment rights
- Fixed interest period
- Repayment rate and flexibility
Regional differences: Why location can influence conditions
It is not only your credit rating that determines the financing conditions – the location of the property also plays a role. Banks assess the risk based on resale value, regional demand and economic development.
In popular cities such as Dresden with stable demand and a solid infrastructure, many banks offer better conditions than in structurally weaker regions, for example. Property values can also often be better secured or even increased in cities in the long term.
For investors, this means that a property in an economically strong location such as Dresden not only offers security, but also greater acceptance when it comes to financing. VIAREALIS® knows the local particularities – and shows you where investments are particularly worthwhile.

Build knowledge: Why you should understand your financing
An often underestimated factor for good financing is understanding. Those who understand the fixed interest rate, repayment structure, subsidy options and contract components make better decisions – and recognize risks at an early stage.
Unfortunately, many buyers rely purely on their bank – and overlook possible disadvantages in the contract. VIAREALIS® therefore takes a transparent advisory approach: we explain how your financing works, what you can influence – and what you cannot.
The aim is for you not only to sign your financing, but to understand it. This is the only way to ensure that you can handle your investment flexibly and confidently in the long term.
Prepare for your consultation – you should bring these questions with you
An effective financing discussion does not start with the bank – it starts with you. The better prepared you are, the more specifically your advisor can address your wishes.
These questions will help you prepare:
- How high can I realistically expect my monthly mortgage to be?
- How secure is my income in the next few years?
- Am I planning special repayments or future investments?
- What type of real estate am I looking for (new build, portfolio, investment)?
- Is flexibility or interest rate security more important to me?
VIAREALIS® supports you with a structured checklist even before the meeting. This saves you time – and you receive a customized offer faster.
Getting a second opinion – why it pays to get an outside perspective
Many buyers go straight to their bank – and take out the first offer that comes along. Understandable, but often expensive. This is because not all banks have the same interest rates, risk assessments or scope for special conditions.
A second opinion is particularly worthwhile for large amounts – for example via an independent financing partner such as those with whom VIAREALIS® works. This allows you to compare several offers directly – neutrally, transparently and without pressure.
A second opinion does not mean mistrust, but diligence. And it often brings decisive advantages in terms of interest rate, term or flexibility.
Your checklist for optimal real estate financing
Good financing starts with structured preparation. This checklist shows you step by step what you should pay attention to:
- Clarify the financing framework: How much equity is available? How high can the monthly installment be?
- Choice of property & location: New build, old building or investment? Which location in Dresden suits your plan?
- Obtain & compare offers: borrowing rate, effective interest rate, repayment, special repayment, eligibility for subsidies
- Check KfW funding: Which programs can be integrated? What needs to be applied for and when?
- Define the loan structure: Term, fixed interest rate, amortization, forward options
- Contract review & advice: choosing the best way together with the VIAREALIS® financing partners
- Long-term planning: follow-up financing, possible unscheduled repayments, property value development
Conclusion: Financing with foresight – your advantage with VIAREALIS®
Financing a property is much more than just choosing an interest rate – it is a central component of your personal future planning. Especially in 2025, when interest rates are at a challenging but stable level, well-founded decisions are more crucial than ever.

Frequently asked questions about real estate financing 2025
Which fixed interest rate makes sense in 2025 – 10, 15 or more years?
This depends on your life situation and risk tolerance. If you want to play it safe today, choose a longer fixed interest rate (e.g. 15 or 20 years) to protect yourself against possible interest rate increases. Shorter fixed rates offer slightly lower interest rates, but uncertainty when it comes to follow-up financing. Our financing partners will help you find the ideal model.
What is the difference between the borrowing rate and the APR?
The borrowing rate is the pure loan interest rate without additional costs. The APR includes all additional costs incurred (e.g. processing fees, brokerage costs) and is therefore the more meaningful comparison value. The effective annual interest rate should always be considered when comparing offers.
How much equity should I bring in?
We recommend an equity share of at least 20% of the purchase price plus the ancillary purchase costs (notary, land transfer tax, estate agent). Those who contribute more (e.g. 30% or more) generally receive better interest conditions and more flexibility in repayment.
What is commitment interest – and how can I avoid it?
Commitment interest is charged if an approved loan is not drawn down within a certain period – often after 6 or 12 months. These additional costs often amount to 0.25 % per month. They can be avoided by negotiating the commitment interest-free period wisely or by setting a realistic construction or payment schedule.
Is a forward loan worthwhile in 2025?
A forward loan can be useful if your current fixed interest rate ends in the next 3-5 years and you want to secure the current interest rate level. It incurs a small premium, but offers planning security. Whether it is worthwhile depends on your remaining debt, market expectations and life planning – our financing partners will give you sound advice on this.
Are there still state subsidies for buying real estate?
Yes – via KfW programs (e.g. KfW 124, 297/298, 300) and regional offers such as the SAB in Saxony. Energy-efficient buildings or families with children in particular can benefit from attractive conditions. VIAREALIS® shows you how to combine subsidies with your bank loan in a sensible way.
What documents are required for financing?
As a rule, the bank requires
- Proof of income (salary, tax assessment notices)
- Proof of equity capital
- Land register extract & exposé of the property
- Revenue and expenditure account
- If applicable, building plans, energy performance certificate, rental income (for capital investment)
Our partners will support you in compiling all documents.
How quickly can financing be concluded?
This depends on the completeness of your documents and the bank processing time. As a rule, 2-4 weeks is realistic – even faster if you are well prepared. VIAREALIS® ensures that your financing request is submitted quickly and completely in order to avoid delays.
