Years ago, I spent an expensive hour with a consultant who helped me list out all my requirements for a house. As I left I was irritated. I thought I knew everything on the list! Why had I spent so much money? Then I went house shopping. The list was extraordinarily helpful. No waffling for me!
The worksheets are on this link. Three of the four worksheets are for planning. The fourth is to document reference checks. are designed to help you have the same experience. Spending time thinking about what you want and need in a housemate relationship helps. Then write it down! It really, really helps!
Good luck and happy hunting!
