Many who buy a house or flat underestimate the maintenance costs. The earlier you analyse and plan for future renovation needs, the more securely you protect your home. Maintenance costs depend directly on the remaining life of the individual components, electrical installations, appliances and wiring. Kitchen appliances or fitted carpets need to be replaced the quickest, while the shell lasts the longest.
Parity life table
Using the parity life table, you can estimate what should last how long, when you need to renovate or refurbish what, and approximately how much it will cost you. It makes sense to set aside 1 to 1.5 percent of the building's new value every year - from day one.
