I agree it's great to build housing. But picture this scenario. You buy a 3 bedroom house on a quiet cul de sac with five other similar houses next to it. At the end of the cul de sac next to your house is a few acres of woods. A builder then builds a 100 town house 5-story building right behind your house. An entrance to the building is put in right next to your house and you now have 200 cars from the 100 units entering and exiting right past your house. The new residents can stare down from the fifth floor of their units into your once private back yard. And of the 100 units, only 10 or 15 are designated low-income.
