Because a CMA is a free service, a potential seller can confirm the accuracy of the value estimate by getting CMAs from more than one real estate agency. Real estate agents make frequent tours of local properties, so they are usually more familiar with comparable sales and listings than appraisers. Agents work directly with buyers and sellers, so they usually have a better understanding of their likes, dislikes and motivations. Agents talk with each other and usually have a better knowledge of the details and conditions which influenced the price of comparable sales. Some agents specialize in certain types of properties and may be more qualified than some appraisers to estimate their value.
Agents have a marketing mindset, and therefore tend to be more creative than appraisers.
They may uncover value-enhancing opportunities through division, assemblage, boundary line adjustments, use permits and remodeling that an appraiser might overlook. However, a diligent buyer will eventually uncover any defects and determine the market value. Attempting to avoid disclosure is an unethical practice. Ocean front and hillside properties may require a geotechnical report to determine setbacks and foundation designs. Other properties may need more detailed inspections of roofs, foundations, underground storage tanks, wells and septic systems.
