How do you ensure you do not end up with a money pit? The single most important expenditure when looking to buy or sell a home is a real estate agent. Not too long ago, there was a push for individuals to buy or sell their house on their own, using a service that listed your house, but left it at that. When you have a medical issue, you go to a licensed physician. When you have a legal issue, you find a lawyer who is in good standing with the American Bar Association. Why would you not want a licensed professional to help you with the most expensive financial transactions of your life? It might seem unnecessary, researching a quality real estate agent to help when you buy or sell a home, but in the end, it has the potential to make the process 100% more pleasant.
