I would LOVE to have the space in the last pic to "play with!!"
Flipper landscaping & builder landscaping are pretty much the same recipe, from what I've seen. Remove the top soil to sell, put a row of non-native shrubs waaaay too close to the house, bonus points for prickly ones, an extra-large shrub on either side of the front door, or for a few $$'s more, a pair of topiaries, a much too big tree on either side of the front walk, cover all other space with sod, call it "maintenance free."
