Final answer:
Rent should generally be paid at the landlord's business place, or their residence if they do not have a business place. The exact location can vary by local law and consulting specific laws or professional advice is recommended.
Step-by-step explanation:
If the rental agreement does not specify where or when the rent is to be paid, the general rule is that rent is to be paid at the landlord's place of business. However, if the landlord does not have a place of business, then the rent should be paid at the landlord's residence.
In some jurisdictions, the law may specify that rent should be paid at the dwelling unit unless another location is agreed upon. It is important to note that these rules can vary depending on the local laws and regulations, so it's always best to consult the specific laws in your area or seek professional legal advice.
