In almost all cases, an open house is just that. Open to the public.
You can simply go take a look.
However, there are some rules that agents work by that you might want to consider.
It has to do with which agent is due any commission should you decide to purchase
It is best, if you select an agent that you are comfortable working with before you start
looking. This agent will provide you with all the information you will need to make an
educated decision down the road. And this agent, if selected to be your buyer agent,
is tasked with looking out for your best interests. With selecting one to be your
"buyer agent", be careful, all other agents are obligated to look out for the best interests
of the seller.
Interview a few agents. Find one that takes the time "up front" to explain all this to you.
Then go look at those properties that fit your needs and your budget.
If you have any questions, feel free to give me a call.
