Webinar Room Rental

As a real estate investor in room rentals, you are constantly looking for ways to optimize the return on your property or properties. Every dollar counts, and every opportunity for improvement is worth exploring. But did you know that the WOZ value of your property, in combination with the WWS, plays a crucial role in your potential rental income and therefore in your return? This is where WWSO (in this context: the effective optimization of the WOZ value for your rental properties) comes in.

Higher Returns from Your Property? The Role of WWSO in Room Rental Returns

As a real estate investor in room rentals, you are constantly looking for ways to optimize the return on your property or properties. Every dollar counts, and every opportunity for improvement is worth exploring. But did you know that the WOZ value of your property, in combination with the WWS, plays a crucial role in your potential rental income and therefore in your return? This is where WWSO (in this context: the effective optimization of the WOZ value for your rental properties) comes into play.

What is the connection between WOZ, WWS, and your return?

Let's explain it step by step:

  1. The WOZ value: The basis for taxesThe WOZ value is the value of your property as determined by the municipality. This value is reassessed annually and serves as the basis for various municipal taxes and levies, such as property tax (OZB), water board tax, and income tax (owner-occupied home allowance). An excessively high WOZ value therefore means unnecessarily high costs.
  2. The Housing Valuation System (WWS): Determines the maximum rent Forsocial housing (and in some cases also liberalized housing below a certain threshold), the maximum rent is calculated using the WWS. This system awards points based on characteristics such as surface area, facilities (kitchen, bathroom), energy performance (energy label!), and... yes, you guessed it: the WOZ value. A lower, but correctly determined WOZ value can contribute to a more favorable rent point score, which can be important for the affordability of your rooms and for preventing rent commission proceedings.
  3. Room rental: Specific dynamicsInroom rental, the WWS system is often applied on the basis of the individual living spaces or a proportional share of the common areas. As a result, small deviations in the WOZ allocation or the points system can have a major impact on the total rental potential of your property.
  4. Return: The ultimate goal Yourreturn on room rental is directly influenced by your income (rent) and your expenses (taxes, maintenance, etc.). By optimizing your WOZ value through a thorough objection procedure—supported by a solid report (WWSO)—you can reduce your costs. By maximizing the WWS points score (if applicable), you can optimize your income. Both contribute directly to a higher return.

The Role of WWSO: Your Key to Optimization

In this context, WWSO stands for the expertise and process of critically assessing the WOZ value of your property, with a special focus on its impact on your room rental strategy and return on investment.

A specialized party such as Renewable Partners B.V. can help you with this by:

  • Thorough analysis of your WOZ decision: We check whether the municipality has correctly taken all relevant factors into account in the valuation.
  • Independent valuation and substantiation: We collect and analyze comparable properties and specific characteristics of your property that may influence the WOZ value. These include the state of maintenance, the actual rental price (for rented properties), the ratio between living space and communal areas, and vacancy rates.
  • WWS analysis in relation to WOZ: We can accurately calculate the impact of the WOZ value on your WWS score and advise you on any optimization opportunities.
  • Submitting a professional objection: We will draft a thorough objection and submit it to the municipality on your behalf, which will significantly increase the chances of a successful reduction in the WOZ value.

Why take action now?

The WOZ value is determined annually. This means that you have the opportunity to object every year. A successful objection can not only lead to immediate savings on your municipal taxes, but also has a continuous positive effect on your operating costs and, indirectly, on the maximum rent you can charge for your rooms.

I want to upgrade my label!

What is the difference between energy label A and A+++?

The difference lies mainly in the degree of insulation and the proportion of sustainably generated energy. An A label can be achieved with good insulation and an efficient installation. For A+++, more is needed: a large proportion of the energy must be generated sustainably, for example with solar panels and a heat pump.

What requirements must my home meet to qualify for energy label A?

The energy label is determined based on the fossil energy consumption of the home, expressed in kWh/m² per year. For an A label, this value is between 105 and 160 kWh/m² per year. With good insulation, an A label is easily achievable. Homes built after 1991 often already have sufficient basic insulation to fall into this category. Solar panels are therefore not necessarily required to achieve an A label.

What are the benefits of an A label?

  • An A-label home is excellently insulated.
  • You enjoy greater living comfort and lower energy bills.
  • You are contributing to a better climate.
  • Many banks offer interest rate discounts on mortgages for homes with an A label (average 0.1%–0.2%).
  • With an average home value of €387,000, this can amount to savings of €500–€1,500 per year.
  • I want to register my energy label!
