I presume your talking about the Low/High/Median
Here is an example that I have put together. It is not a Standard Boiler Plate. You could take this an modify it for your Subject I have included the FNMA Selling Guide Reference that Include in my reports
-----------------------------------------------------------
SUBJECT VALUE ABOVE OR BELOW PREDOMINATE NEIGHBORHOOD PRICE
PREDOMINANT PRICE VERSUS OPINION OF MARKET VALUE - The predominant price on page one is the MEDIAN of the value range for ALL residential properties within the subject neighborhood. ... These sales have not been verified or adjusted for any amenities, sales concessions, or any other significant value related differences. The Lowest Price or Highest Price may or may not have been excluded.
The Neighborhood/Market Segment contains homes of various ages, GLA, and designs. The subjects opinion of value may be below or above the predominate price. Relying solely on the predominant price can be misleading. The predominant price represents only a median price of properties. The majority of the properties may be either below or above the predominant price. The only concern regarding the subject value in relation to the low, high, and predominant price would be if the value is below the low price or above the high price. This may suggest an under or over improvement.
The value of the subject is well within the established median range of prices and is not an over/under improvement.

Price Range and Predominant Price
The appraiser must indicate the price range and predominant price of properties in the subject neighborhood. The price range must reflect high and low prevailing prices for one-unit properties, two- to four-unit properties, condo units, or co-op units depending on the property type being appraised and the appraisal form being used. Isolated high and low extremes should be excluded from the range, which means that the predominant price will be that which is the most common or most frequently found in the neighborhood. The appraiser must state the predominant price as a single figure using whole numbers.
