The week we picked our lot we viewed several models and our sales agent took note of what we liked. At the end she priced the house out with all the major options we wanted. Using options/upgrades from the various houses. Very clever way TV does this now.
No big deal and I can't believe your agent won't do this for you now. Takes about 15 minutes. To get individual pricing for each option is more difficult because of how their program is built.
I'm pretty sure this was done on purpose but that's my humble opinion.
We actually viewed two houses recently built on our visit and the owner mentioned that she wanted a fridge that came out to the counter. She could not get it through TV, but you can always ask.
You can buy the basic appliance package and sell off those appliances. There is a great demand in TV and you should get fair prices.
Good luck with your build! Just be prepared to have plan A, B and C in place and it should be a piece of cake.
