We are in the same process a little ahead of where you are at.When we went thru the model every thing we seen was standard for x amount of dollars when you go to pick out counter tops ,siding, carpet,wood floors, paint, windows etc. We started with the standard then upgraded or had the option to downgrade or go cheaper when we went to pick stuff out. There are an unbelieveable amount of options out there esp upgrades.When we didnt spend the same dollar amount as the standard we applied it to something else for an upgrade. Everything is negotable and money can be moved around.The only thing we had some problems with was how the house sits on the property you want to see how the house sits on the property how the drive way sits with the grade of the lawn front back and side of house where the storm drains and easement are compared to property lines and the house.Look at it all.I wanted to pour a 15 by 30 pad on the side of the 3rd stall she said ok when we went to look at the foundation we noticed there wasnt enfough room we were not very happy look at it all before you agree
