Make sure to factor in additional costs such as utilities, internet, and insurance. 6. Consider using a real estate agent to help you find the right property. 7. Be aware of the local laws and regulations regarding renting and leasing," remarked another expat who made the move to Nordrhein-Westfalen, Germany.
