Calculating maintenance costs for your property correctly

A sound investment calculation lives or dies by realistically estimated maintenance costs. Anyone who underestimates them often faces unpleasant surprises after the purchase.

Which fixed costs arise

Recurring expenses form the basis of any cost analysis. These include property tax, water charges, insurance premiums and administration fees. With condominiums, there are also service-charge contributions, from which the owners' association builds maintenance reserves for shared areas such as stairwells.

Building your own maintenance reserve

For individually used areas – such as balconies or water and electricity connections – the owner bears responsibility. It is advisable to set aside a maintenance reserve per square metre per year in order to fund future repairs such as roof refurbishments or plumbing renewals.

Calculating with benchmark figures

Experts recommend planning not only for the purchase price and around 10 to 12 percent in ancillary costs, but also for 3 to 5 percent for maintenance. However, these benchmark figures depend heavily on age, condition and building services. An on-site inspection by professionals provides the most realistic assessment.

Taking local factors into account

In addition, location-specific factors should be considered: pest problems, ground moisture or accelerated wear and tear caused by traffic noise. Only a location-appropriate calculation makes it possible to set the necessary reserves with precision. We would be glad to support you with a well-founded valuation.
