It is probably not anything so premeditated. They have a number of things to promote in a small area. Full promotional sites take time to put together. That URL is as close to a static single page site you can build. It screams quick solution as a stopgap before committing to something more time/cost intensive. Since they are trying to move condos, they want to start getting names of people interested ASAP.

Digital/Marketing agencies do this all the time. If one or both of those two large proposals move forward, maybe they keep it. It's more likely the domain gets forwarded to one of those properties once they have full sales materials.

The reason there isn't say a Streeterville one is because there are dedicated sites for everything they have there. All you would be doing is adding an additional step to the sales funnel. And that funnel doesn't even matter so much for rentals since they don't need presales. OBP has condos, but the rental portion didn't necessitate generating sales quickly as a condition to start construction.
