Great question! Here are top 5 reasons in my opinion
1. It is "Free" to use your own buyer's agent. The seller puts up all the commission and it is split in half so why not get the free assistance?
2. Agent know about properties earlier than pretty much everyone else. I have a listing coming next week. I already have 8-10 agents who have buyers that are ready to see it because I told them about it. Those buyers will beat the general public to it.
3. Agents do the work for you. Do you want to try to line up showings yourself, gain access, line up a route, get seller's disclosures ready? I'm guessing no. A good buyer's agent will do that for you.
4. They know what comes next. Real estate deals can be tricky with lots of inspection issues, closing issues, appraisal issues and MUCH more. An experienced agent has seen it all and can guide you through it efficiently so it is on their plate and not yours.
5. Access to market data. How do you know what a fair offer is? Most don't. Agents are thee to help you with a market analysis to make sure the house you want to buy is priced right, and based on that, you will not overspend on the house.
I have two fantastic buyer's agents and I know the time and effort they put into each deal to ensure happy clients. In my opinion, everyone should have a dedicated buyer's agent.
