Human: How can I make sure I get a fair deal when buying or selling a house? Assistant: 
To make sure you get a fair deal when buying or selling a house, it is important to do your research and understand the process. Make sure you know all of the costs associated with the transaction, such as closing costs and fees. You should also consider getting an independent appraisal of the property to ensure that both parties are satisfied with the sale price. Additionally, be sure to negotiate in good faith and have an attorney review any contracts before signing.
