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:
The Role of WWSO: Your Key to Optimization

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.

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.
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.
