Yes, it's shocking they would abandon a project like that. We had a situation in our little town where the city was going to use redevelopment funds to build an apartment building with retail on the ground floor. The recession hit, the state withdrew all redevelopment money and the city did not have enough to finish the project. Halfway built, it sat unfinished for five years. The city was finally able to sell the land for one million, but they had put five million into the project, so it was a huge loss.
If they sell the land they may or may not get back what they put into it, depending on if the potential buyer can adapt the finished parts to their needs, but unfinished work is not really a selling feature.
