Heh Mr. Wonderlick ! Who pissed in your corn flakes ? And yes you can improve the value of a brand new house ! You can add hardscape, landscape, remodel the kitchen and baths with granite, or more add square footage to the house. And yes the most expensive house on the street is the hardest to sell and appraise. And yes I am a real estate professional ! I appraise houses, invest and develop real estate.
