My household has made literally millions thanks to a combination of book royalties from the wife and elixir consignments from the husband. I have over 3 million simoleons in the household account, and that's not even counting the business investments (I completely own all the investment business in Sunset Valley) or all the physical possessions.
So, I can place a 64x64 empty lot at various places on the Sunset Valley map, and use them for whatever.
I'd like to make at least one of them a Resort. And due to my massive funds, I can get enough decorations and amenities to make it an instant five-star resort.
What is a good price I can charge customers, the highest price where customers will pay?
