Thank you for the detailed explanation! 

If the Appraiser chooses to include converted living spaces as GLA, the Appraiser must include an explanation detailing the composition of the GLA reported for the comparable sales, functional utility of the subject and comparable properties, and market reaction.”I am a layman on this matter, nonetheless this is my interpretation: Unless this "4th Bedroom" has a permanent heat source, is completely finished out according to spec with the house, and comparable to neighboring properties with finished basements, then there is a good chance it will not appraise.

@Joe Villeneuve thank you for that explanation

If you need any explanations shoot me a message.
