@Antoine Martel. You are either very lucky, a great interviewer or both.
I have a website that connects investors with investor friendly Realtors around the country. (I can't mention the name or my post will be deleted but look at my tag line.) I can not tell you how hard it is to find them. I struggle to find great agents in most markets. (If you have any suggestions of folks I should call, please PM me. I would love to reach out.)
Everyone has different standards as to what they mean by investor friendly. Some just want agents who will send foreclosure or distress property lists and write tons of offers. Any agent can do that. Others want a bit more.
My standard tey must be both licensed and investing for a number of years and no way you get that from a simple Zillow list. There are many markets I've tried to research where I came up empty attacking the puzzle from many different angles. That is not to say there are not investor friendly Realtors in those markets. Maybe I should have just called Zillow agents.
If you are blindly calling, certain companies, RE/MAX being one, allows you to screen agents based on specialty. Investing is one such screen.
But know anyone can call themselves an investor friendly agent. They do not need to have the experience to back it up.
Many agents on BP respond to posts and say they are investor friendly. I look up many of them and have added a few to my site but several - too many - I find out have been licensed 6 minutes. They may know investments but they don't know the ins and outs of selling a home and where the minefields are.
Again, bottom line, ask the agent how long they have been licensed and if they personally invest. If both are positive answers, go deeper but if either one is the wrong answer, move on no matter how much you like them.
