Hi group

I'm buying a 30" Trenton in Mount Pleasant in a couple days....but am nervous.
It'll be my first home and I'm having the hardest time imagining the look of it. When I drive by completed ones that I think are Trentons - I'm not sure if it's the right model. Can the dining, kitchen, and family rooms fit full furniture sets?
Does anyone have pics of the in and out of the finished house that you'd like to share?
Any tips on the buying / contract portion?
Did they negotiate, should I ask any specific questions?
Any help or assistance is appreciated.
Thanks in advance
Michelle
