Try this..

SELECT D.*,DC1.Comment 
FROM Deals AS D
   INNER JOIN DealComments AS DC1
        ON D.DealId = DC1.DealID
    INNER JOIN 
    (
        SELECT 
            DealID,
            MAX(CommentTime) AS CommentTime
        FROM DealComments AS DC2
        GROUP BY DealID
    ) AS DC2
        ON DC2.DealId = DC.DealId
            AND DC2.CommentTime = DC1.CommentTime
