There are 3 common approaches, or Appraisal Methods, used by Appraisers to establish property value. After thorough exercise of all 3, a final value estimate is correlated. When evaluating single-family, owner-occupied properties, the Sales Comparison Approach is heavily weighted by an Appraiser.

1. Cost Approach – A formula is used to obtain the property value: Land value (vacant) added to the cost to reconstruct the appraised building as new on the date of value, less accrued depreciation the building suffers in comparison with a new building.

2. Sales Comparison Approach – The Appraiser identifies 3 to 4 comparable comps, recently sold properties in the neighborhood, ideally, sold in the previous 6 months and within ½ mile of the subject property. A comparison is done between the recently sold properties and the subject property including square footage, number of bedrooms and bathrooms, property age, lot size, view, and property condition.

3. Income Approach – The potential net income of the property is capitalized to arrive at a property value. Capitalization is the process of converting a future income stream into a present value. This approach is suited to income-providing properties and is used in conjunction with other valuation methods.

The mortgage company owns the appraisal even though the borrower paid for it. This is because the mortgage company orders the appraisal on the borrower's behalf, and the Appraiser lists that mortgage company on the report. The borrower does have the right to receive a copy; however it's the mortgage company's discretion to give the borrower the original appraisal report.

The property seller sets the price, especially for residential property, not the Appraiser. Sellers usually don't order an appraisal because they want to obtain the highest price for their home and therefore don't want to be bound by the Appraiser's assessment.

The real estate agent receives a percentage of the price as compensation and often represents the seller in the transaction and assists them in setting the sale price. They perform a Comparative Market Analysis (CMA), which real estate agents in most states are allowed to perform without an Appraiser's License or Certification. The CMA is vital to the agent's preparation for a listing examining recent property sales in the neighborhood to arrive at a listing price. Typically the agent will suggest a price to the seller based on the CMA however the seller may choose to list their property for a higher price.
