Moving into a new house...fiance and i cant agree on how to decorate HELP?

my fiance and i just bought our first house and we are both excited to remodel and decorate it...but we have totally different ideas...i told him he can decorate his game room however he wants and hes excited about that but he also wants to decorate the entire house however he wants and he really just doesnt have good taste and i would like everything to be neutral so that we can have a high resale value.....i guess i dont really have a question i just need advice....or if you can let me know magazines or websites with good ideas.....thanks!!!!
