Relocation usually means one of two choices if you're NEW in GERMANY.
1. Hire a relocation agent
Advantages: 1 on 1 service, bespoke requirements, expertise from somebody with local knowledge
Disadvantages: High cost…often a deal-breaker for young professionals if their employer is not paying
2. Going it alone
Advantages: No cost, plus the individual knows their own requirements best
Disadvantages: Limited local knowledge, language barrier, time consuming, difficulty getting appointments, risk of signing an unfavourable contract.
