When Lennar says they have the "everything home" they mean that everything is wrong. They did not caulk the windows or outlets leading to leaks when it rains.
My "energy star" home if filled with drafts. The drywall was not taped in the corners or ceiling leading to hairline cracks everywhere. The cheapest materials were used including the upgrades that I over paid for. Unskilled labor was used so the walls are crooked.
I can hear every step someone takes upstairs because of poor instalation. The list goes on.
I would tell anyone not to buy a Lennar home. I made a comment on my facebook so all can see.
