When you apply for a mortgage, your lender typically requires the property to be appraised by one of their approved appraisers. This practice helps create more consistent appraisals and gives you assurance that the appraiser is properly licensed and certified. Even though the home appraisal is the lender’s requirement, it’s the borrower’s responsibility. You usually pay for it as part of the mortgage costs at the time of closing. The cost is typically around $300 but can be more depending on the price of the property.

There are two primary appraisal methods for residential property. In the sales comparison approach, the appraiser compares the property with three or four similar homes that have sold in the area, often called comparables, or comps. The analysis considers specific components, such as lot size, square footage of finished and unfinished space, style and age of house, as well as other features such as garages and fireplaces.

The cost approach is used more for new property and is based on reproduction costs. The appraiser estimates the cost to replace the structure on the property if it were destroyed. The appraiser then looks at land value and depreciation to determine the property’s worth.

The appraiser gathers information for the appraisal report from a number of sources, but the process often begins with a physical inspection of the property inside and out. Additionally, the appraiser may look at county courthouse records and recent reports from the local real estate multiple listing service.

The appraisal report generally includes:

• an explanation of how the appraiser determined the value of the property
• the size and condition of the house and other permanent fixtures, along with a description of any improvements that have been made and the materials used
• statements regarding serious structural problems, such as wet basements and cracked foundations
• notes about the surrounding area, such as new or established development, rural acreage, and so on
• an evaluation of recent market trends of the area that may affect the value
• a comparative market analysis that supports the appraisal
• maps, photographs and sketches

A common misunderstanding is that the appraisal amount is only for the house itself. In fact, the figure appraises the total value of the home and any other permanent structures, along with the land that the house is built on. This appraisal figure also determines the loan amount you can get to buy the property.
