Final answer:
When appraising a single-family home, the appraiser is required to state that the income approach was not developed and explain the reason for it.
Step-by-step explanation:
When appraising a single-family home, if an appraiser decides not to develop the income approach, the requirement for reporting this on the URAR form is to state that the approach was not developed and to explain the reason the approach was not developed. The income approach is commonly used to determine the value of income-generating properties, but it may not be applicable to single-family homes where the income potential is not a significant factor in determining their value. Therefore, the appraiser should provide a clear explanation as to why the income approach was not considered.
