We purchased a home last year, (built in 2005)...and have a laundry list of builder defects, which Lennar says they are not responsible for. To top it all of, the Lennar Reps were hateful that we were bothering them about these defects.
A leaking roof above my daughters bed is no laughing matter to me when we are buying a NEW home. Shady people working for Lennar and wherever Mr. Lennar is, they probably don't care as long as cash is flowing. IM now stuck unlsee we want to sell for half what we owe or walk away...but you can still save yourself a lot of anguish.
If you don't care about quality, then buy from Lennar.
