I bought a new Lennar home less than a year ago. I read the horrible online reviews and I should have known better. The workmanship is shoddy, at best. The treehouse I built myself as a pre-teen is of better quality. There is zero management by the construction crews, they do whatever they feel like and leave beer cans and garbage everywhere in my new neighborhood. The construction crews have destroyed multiple yards, broken a water main, hit my truck THAT WAS PARKED IN MY DRIVEWAY, and completely destroyed our community mailboxes. Lennar refuses to respond to any of this, and expects homeowners to pay to replace this. Don't walk, RUN AWAY FROM LENNAR.
