Stopped by the sales office today, they actually have lot 58? for 599K, it's a plan 1. They also have another plan one for 610K, slightly better location since it is a corner unit with a bigger lot and side yard.
I liked plans 1 and 3, thought 1 was a good size for a starter home. 599K seems a bit high still though, I'd pay like 500K for it.
Reservations: Too close to the train tracks, walked by there at night and could definitely hear the train since it's literally right across the street. High mello roos, and its Tustin. And last of all... no refrigerator!!!
