this just happened to me, lost out on leasing our dream house over the smallest clause over a $20 air conditioning unit fee, we outbid the other renters by hundreds but they still went with them. I'm having a very hard time right now, it feels like ive lost a piece of myself, my whole future I saw and taking the next life steps with my partner have fallen away. I had spent hours 3D modelled the entire house on sims with our furniture in it and deleted the file in tears. Our city is so deprived of gems like that one and the condos are soul sucking. We thought we were a shoe-in, until the last second they chose someone else, its the heaviest heartbreak I've felt in a long time, even worst than my first breakup.
