Been renting this place, and the landlord's agent is from Orange Tee. The agent keep arranging for people to view the house to sell the house. I can understand that the landlord wants to sell the house and facilitate for viewing, but the agent keeps requesting for multiple viewing last minute and as and when her potential buyers want to view, disrespecting my time. Also, during COVID now, agent did not take safety precautions for viewers and my safety. It is disturbing my peace of mind as a rent payer.
