In appraising most residential properties, a real estate appraiser relies primarily on the:

The reproduction cost approach estimates the cost to construct an exact replica of the property using the same materials and construction methods. While it can be useful for unique properties or new constructions, it is not the primary method used for typical residential appraisals, as it does not consider current market conditions and buyer preferences.

Similar to the reproduction cost approach, the replacement cost approach determines the cost to replace the property with a similar one using modern materials and techniques. While this method can provide useful information, it is not the primary focus in residential appraisals, as it does not reflect market sales data which is critical for determining value.

The income approach is primarily used for investment properties by estimating the income potential of the property. This method is less applicable to most residential properties, as they are usually owner-occupied and do not generate rental income. Thus, it is not the primary method for appraising such properties.
