When using comps, it's important to make adjustments for significant differences between your property and the comparable sales. Start by identifying key features that differ, such as square footage, number of bedrooms or bathrooms, lot size, or recent renovations. You can then estimate the value of these differences based on local market trends or by consulting a real estate professional. Keep in mind that some features, like location or views, can be more challenging to quantify but may have a significant impact on value.
