I've been a realtor for 29 years. There is a lot to do in Real Estate that most people don't understand or have a clue how involved it is. Buyers can search for homes on the Internet, but do they know what questions to ask during the process of buying?
Do you know how to negotiate with a Realtor or a Seller?
Do you know how much it costs to purchase a home? I can refer you to reputable local lenders who can help you.
If Real Estate is not your profession, you should not take on the task of buying or selling alone.
