Hi,
So this agent wants you to sign a exclusive buyers agency agreement which he wants you to sign, but what you want to know is this for one house, one block or one square mile????
As an investor I use a lot of agents, I use them according to the area they are based in, notice I did not say area of expertise as I only find 1 or 2 in 10 really have the drive and experience to potentially qualify at some level as an expert in there specific market.
Although most agents are professional in presentation and do well showing listings to home owner buyers, they are far from qualified to work exclusively for an investor! Most agents have no real estate investing education, no experience and no expertise to work on behalf of investors.
I don't know what state your in, but pick a town or city 2 or 3 hundred miles away and ask them to meet you there to look at a property, 99 out of a 100 will tell you "NO"!
I invest in Arizona and Nevada as primary markets, I use an agent for example who knows Chandler AZ for my investments in that area and if I want to invest in Peoria AZ I use an agent who is familiar with that area (Chandler & Peoria are 60 miles apart but part of the greater Phoenix area), and if I want to buy something in say Williams AZ (West of Flagstaff) i use an agent in that area.
I would simple tell this agent if you want to do business together great, but I buy real estate all over and I am not going to limit myself to one agent or agency, but don't stick yourself in a position to limit your ability to operate or function!
If this agent say's it's my way or the highway tell him goodbye, and find some other real estate agents to work with!
Good luck,
GR
