Yes. Unless you are highly experienced in real estate transactions, or you are a real estate broker, you should always have a lawyer oversee and advocate for you in a real estate deal. This is a transaction that includes large sums of money and lots of potential liability. Realtors take 4-5% of the transaction to sell the home. It makes perfect sense to spend $1000-$2000 on an attorney to make sure everything is done correctly, and in your best interests.
