Fit for the future?

Climate change, rising electricity and gas prices, inflation ... It's hardly surprising that, especially now, people are thinking about how to protect themselves from rising energy costs in the future. The trajectory set by the German government is clear: by 2030, a whopping 80 percent is to be generated from renewable energy sources and 60 percent less CO₂ consumed. In the coalition agreement, the government decided that photovoltaic systems would be mandatory on commercial roofs and the norm on private roofs. There are now also laws in some German states, such as Hamburg, Berlin, and Baden-Württemberg, which have introduced mandatory solar for new buildings and renovations gradually or plan to do so over the next few years. For property owners, this means that more energy-efficient renovations and modernizations are needed. But how do owners go about it? Is it worth it? And how do you apply for a loan? We'll explain it to you. 

What exactly qualifies as a modernization?

To avoid confusion, let's first clarify the difference between renovations and modernizations. When you hear the term renovation, it's about remedying a defect or damage, i.e., a deficiency, through extensive repairs. The goal is more of a restoration than a quality improvement. Typical renovation measures are, for example:

  • Mold removal

  • Facade repairs

  • Energy renovations

  • Balcony and terrace renovations

A modernization, on the other hand, can be seen as an upgrade or a goodie, which increases the living comfort and/or makes a building more energy-efficient, i.e., something like:

  • New water-efficient toilet cisterns or faucets

  • New ventilation systems

  • Elevator installations

  • New heating systems, e.g., with heat pumps

  • Installation of solar energy systems

  • Improved insulation, roofs or windows

Modernization loans are typically nothing more than earmarked installment loans (up to 50,000 euros) or construction financing (over 50,000 euros). They are directly linked to your property and are only paid out when you can prove that the planned measures have been implemented.

Are owners obligated to modernize and renovate?

Yes and no. Generally speaking, German law does not require you to update or renovate. So you don't have to redo a bathroom or kitchen every couple of years or anything like that. But there are some cases in which there are certain renovation regulations, for example, when:

  • the roof of your purchased or inherited house does not comply with the minimum thermal insulation (applies if you became the owner of a building existing at the time after February 1, 2002) and you do not live in it yourself. The roof must be insulated following the minimum requirements.

  • the heating system is over 30 years old, and you do not live in the building yourself. Then the heating pipes may need to be insulated, and the boiler replaced if they do not meet the standard.

  • you renovate at least 10% of the exterior facade. There are specifications on how it must be insulated if you already plan to tackle this.

  • the health of the occupants is at risk, e.g., in the case of mold infestation, dry rot, or water damage.

The Building Energy Act (GEG) 2022

With the new building energy law (GEG) from November 1, 2020, there are new energetic requirements that new buildings and existing buildings must fulfill. Our colleagues at Dä will explain more about what the GEG entails.

Why is modernization worth it?

Okay, so it's not a must to modernize your property. But there are some excellent reasons why it can make sense to spend a little money on these projects. 

Reason 1: You save money in the long run

When you renovate or modernize a property, you have an initial investment, but in the long run, you can also significantly reduce your utility and operating costs. New insulation, modern heating, or new windows with triple glazing can ensure that you or your tenants have to heat much less. By installing and using a photovoltaic system or battery storage — which you can either use yourself or fully feed into the power grid — you reduce or offset electricity costs. And water-saving fixtures will also make future bills cheaper. 
If you use the property yourself, you can deduct 20 percent of the modernization costs, up to a maximum of 40,000 euros, spread over three years. Speaking of saving money: There are attractive development loans from the KfW with excellent conditions for many modernizations and energy-efficient renovations. So your investment will pay off relatively quickly. You can find out more about subsidized loans under "Planning a modernization.“

Reason 2: You future-proof your investment

You know when they say it's always good to be prepared? This also applies to real estate. You'll be better off in the long run if you take care of things before they become problems and you have to carry out extensive renovations. If you're unlucky, you may be in for a nasty surprise sooner or later, which can get expensive. By modernizing, your costs are much easier to plan
But modernization is also a good idea if you want to develop rental income as part of your investment strategy. According to the German Civil Code (BGB), the rent increase may amount to up to 8% of the modernization costs falling on the apartment each year (we explain more in detail below under the item "Planning a modernization.“) Since modernizations are also beneficial for tenants, they are usually well accepted. Nevertheless, you should proceed correctly and fairly. Otherwise, your tenants may object to the rent increase.

Adjusting the rent fairly

For various reasons, you should continually develop the rent of your property. Otherwise, the resale value will also suffer sooner or later in addition to your return. However, you should always be fair to your tenants when increasing the rent. Here you can find out what you need to pay attention to. 🤝

Modernizations also increase property value. So if you ever want to sell, that's another plus.

Reason 3: You're helping to protect the environment and improve sustainability

If you're one of the many people concerned about climate change and looking for ways to get involved, an energy modernization or renovation is a great approach. After all, you can significantly reduce the CO₂ emissions of your house or apartment and thus pave the way to climate neutrality. Germany aims to reduce emissions by 65 percent by 2030 and be climate neutral by 2045. According to a study by McMakler, however, we are still far from achieving this goal. So far, only 13 percent of all energy certificates issued for German properties have an energy rating of B or better. So there's definitely still room for improvement. 

How do you plan a modernization?

If you want to carry out an energy modernization or renovation, you can apply for a state subsidy, aka a KfW loan, as briefly mentioned above. The KfW offers various subsidized loans for existing properties and new buildings. However, you can't do this alone, but only directly via a bank or indirectly via a mortgage broker like us. Our financial professionals will find the right bank for your modernization loan and apply for the corresponding KfW funding. 

Apply for funding? You bet!

Make an appointment with Janina

Before you apply for the loan and start the refurbishment or modernization, we recommend hiring an energy efficiency expert. This person will take stock of the situation, tell you which measures are recommended, and draw up a corresponding concept with a renovation roadmap for your property. After implementing the modernization measures, you will need this person anyway to obtain the "confirmation after implementation" and to receive the repayment subsidy

Lightbulb light

Then you need the financing, subsidy application, and a contractor to carry out the renovation or modernization work. However, you shouldn't officially commission the company until you've successfully applied for financing and funding. Otherwise, you won't receive it. However, you can already obtain cost estimates to gauge the required loan amount.

At least three months before the start of construction work, you must inform your tenants in writing about the upcoming work and any rent increase. Your letter must contain the following:

  • Start of construction work

  • Duration of the works

  • List of planned measures

  • Amount of future operating costs

  • If applicable, new rent amount

However, you may only increase the rent if you haven't agreed on a graduated or index-linked rent or if you're legally required to. Otherwise, you're obligated to bear the costs yourself. Here are a few tips to calculate the maximum rent increase:

  • You have to deduct the maintenance costs that the modernization eliminated. This means costs that you would otherwise have had to spend on renovating. 

  • You must also subtract public subsidies and interest savings from the modernization costs.

  • The rent increase may not exceed 8% of the remaining amount per year. 

  • The rent increase may only increase by a maximum of 3 euros per square meter every six years. So if the 8% is above that, that's your cap

If you feel unsure about calculating the new rent amount, you are welcome to contact our financial experts. We will be happy to work it out with you.
Once everything has been settled with your tenants, the change can be carried out as scheduled. If you are a skilled craftsman and can professionally perform the modernization work, you can do it yourself and save some of the modernization costs

Once the work has been completed and the expert has given the official go-ahead, you'll be credited with your repayment subsidy

Get your modernization loan with ease

So, if you need a modernization loan, Urbyo is the right place for you. During the consultation with your financial expert, you'll find out how high your maximum loan can be and which subsidy loans you can apply for. In addition, your contact will help you prepare and submit all the documents the bank requires. These include documents about your financial situation, cost estimates, and information about the property.

Don't worry: We'll find a suitable financing model for you and make the modernization process go as smoothly as possible. Your property will be fit for the future in no time.

Avoid fails during energy-efficient refurbishment

  1. Poor planning: Uncoordinated implementation of refurbishment measures without taking into account their impact on the overall concept can lead to damage and subsequent costs.

  2. Window replacement: New windows can improve thermal insulation, but if the entire building is not well insulated, thermal bridges can occur. Replacement can also lead to moisture damage.

  3. Professional implementation: DIY (Do it Yourself) windows can lead to structural damage. A specialist company takes insulation and details into account to avoid moisture damage.

  4. Photovoltaics for roof renovations: When renovating roofs, the integration of photovoltaics should also be considered in order to save costs and ensure efficient planning.

  5. Efficiency of the heating system: Switching to a modern heating system, e.g. a heat pump, is pleasing, but the efficiency depends on the insulation and the heat distribution system.

  6. Clarify before buying: When buying a house, you should clarify any renovation measures that have already been carried out, the dimensions of the heating system and the quality of the insulation.

  7. Realistic expectations: The financial benefits of energy-efficient refurbishment only become apparent after a few years, and the choice of high-quality materials may be questionable if you intend to sell.
