Condominium – The first digital contribution calculator

The optimal contribution amount in your community renovation fund can be calculated very easily and quickly with the Houzy contribution calculator for condominium property.

The online calculator rely on the results of the "HouzyCheck" digital state analysis. This examines the need for renovation of private and common owned components and calculates the resulting renovation costs.

Based on this previous analysis of common renovations timing and costs, Houzy forecasts the proportion of the renovation fund that can cover the associated costs. You can then use the contribution calculator to calculate the optimal amount of your contribution to the renovation fund.

To calculate the required contribution margin, you only need three details of the current renovation fund. In most cases, you can specify these separately from the administration or the co-owners and thus start directly with the examination of the fund.

What information does Houzy need for the renovation calculator?

FAQ arrow

Important for the evaluation of the renovation calculator are the basic details such as address, year of construction and house type. Information on the materials of the various components (e.g. the roof or the façade) as well as renovations already carried out make the renovation calculator much more accurate. In the "Pro version", additional information on the standard of construction and condition can be entered. Rooms and building components can also be entered several times and more specifically, which leads to an even more precise result. In short: the more information you can provide, the better.

Why is the renovation calculator free of charge?

What should be considered when buying an apartment?

FAQ arrow

Before buying an owner-occupied apartment, you should definitely take a look at the condominium regulations, because with the purchase you accept the regulations of this community. The resolutions and minutes of recent owners' meetings also provide important information about decisions, such as upcoming renovations. In addition, it should be clarified in advance what the status of the renewal fund is and the annual contributions of the condominium owners. Buying a condominium also means that you have to help finance all upcoming renovations. So if the roof is renovated a year after the purchase and there are no funds in the renovation fund, the new owner will be faced with major expenses. With the Houzy renovation and renewal fund calculator, such expenses and risks can be identified even before the purchase.
