Decorations & organizing detrimental to buying buildings

I had to "limit" myself to purchasing. 1 day a week I purchase a building and 1 or 2 plots of land. This week it will be Nelson's house. But in honor of Thanksgiving I will also purchase another Kwik-e-mart for Nelson's neighborhood. Since I do a lot of the hour tasks I decorate accordingly. Keep eyeing the Post office building as it sits there with no quests to perform but holding off. Have to get the Apt and Channel 6 building first!!
