The burden of the past: Why legacy systems in real estate management become a risk

Legacy systems are usually historically grown IT solutions that are often based on outdated programming languages or architectures. They may have been reliable once, but their disadvantages prevail today.

High operating costs and inefficiency

One of the biggest drawbacks of old systems is the exploding operating costs. Maintenance requires highly specialized staff, which is often difficult to find and expensive. Every small adaptation or extension becomes a complex, time-consuming and error-prone project.

• **Manual processes:**Old software rarely supports today's usual automation standards. This leads to employees still having to perform routine tasks such as rental management, additional cost accounting or document deposit manually or with high effort.

• **The connection of new, specialized tools (e.g. digital deficiencies management, IoT integration or modern CRM systems) is often impossible or can only be realized with expensive, unstable workarounds.

vulnerabilities and compliance risks

Security is of utmost importance in the real estate industry, which manages sensitive tenants and object data. Legacy systems are a massive risk here.

• Old technology: Without regular security updates, these systems are vulnerable to modern cyber attacks. A successful attack can lead to data loss, operational interruptions and massive reputation damage.

• GDPR compliance: Compliance
