Don't use a buyers agent if you know what you are doing
A buyers agent is not needed if :
-you know what you are doing,
-know the general price range of the area/property and generally follow the market
-you have a pretty specifically defined property you want.
-you generally have bought a property before
-you are fairly good at negotiating
Although it sounds like a steep criteria, it really is not. It basically means that if you have done your homework and are fairly educated, go without the buyers agent.
For a good perspective behind the motivation of most real estate agents, read
Freakonomics:
Here is an excerpt of the relevant point:
"In Chapter 2, for example, real estate agents are essentially accused of failing to serve their clients' needs as a result of the incentive structure that prevails. Agents are paid a commission based on the selling price of a house. If an agent holds out for an extra $10,000 on the sale of a $300,000 house, that's a big deal for the seller, but a mere $150 for the agent. As a result, the Steves suggests this incentive structure drives real estate agents to go for churn instead of the highest possible price."
I did not user a buyers agent on my last purchase and saved myself a lot of money, and a lot of hassle dealing with competing offers. here is why.
In my experience, not having a buyers agent gives you a lot of leverage in two ways: commission and offer price.
The sellers agent/broker will usually act as both buyer and selling agent with a negotiable commission usually at 4% (300,000*0.04 = $12,000) instead of 5% (300,000*0.05 = $15,000).
In the situation where you having a buyers agent, the selling agent and buyers agent split $7,500 each in the example.
However, in the situation where the agent/broker acts as both the buyer and the seller, the agent/broker stands to make $12,000, or an added incentive for them of $4500.
Given the above example in Freakonomics, the agent then becomes much more amendable to your offer, since regardless of the offer prices, given now they stand to make higher commissions, they make more money, and are more apt to deal with you.
Either way, the seller has a much more profitable interest to deal with you than a competing offer coming from a buyer with a 'foriegn' buyers agent.
I have not only done this on my last purchase but in a lot of offers leading up to my purchase and in each one found myself with much stronger negotiation power.
You want to really test a buyers agent and see how they are driven by commission rather than your best interest?
Spend three weekends in a row having them show you properties and show some moderate interest, but mention none have yet to really peak your interest. On the 4th weekend, show a little more interest then moderate, and see how strong they push you to buy.
