Like a box of chocolates!
In the summer of 2012 I entered the house for the first time as the official owner. Before purchasing it I had done an inspection of the structural integrity of the house, so I knew that there was some restoration work to be done. However, the work turned out to be a lot more than I had expected. Naively, at the moment of signing the contract it looked like a good deal to me, but later on I realized that I should have gotten a big discount instead.
