When you have a good plan for your property investment, you can make sure that you are doing the right thing. A part of planning is to check ahead the achievements and the portfolio of the property management office that you would ask help from. You might even stumble upon their advertisements that can give you the first impressions of what kind of office they are. You might be able to read about them from magazines and billboards and other media so you would be able to have an idea what they are all about. How they advertise can say a lot about what principles and ethics they uphold in their office and would even determine how they will be treating you when they make dealings with you. Make sure they are a stable group with how they perform their advertisements. You might also give it a try to look personally at their properties. Their properties can also have a big impression on you if you can trust them with responsibilities. You can also ask opinions from the people who were able to work under them. You can also get the opinions of those who had been their tenants so you can see if their work is satifactory.
