I bought a 16 unit apartment complex that was a expense nightmare, with low rents, that I eventually gave up trying to make profitable. 

This experience will help you prepare for more complex real estate deals in the future.

The sheer complexity of this matter alone is enough to illustrate the problem, but this is just the tip of the iceberg.

It just adds complexities and costs without any benefits. 

One complex I own in replaces up to the studs.

These systems are becoming more sophisticated and (my favorite) capable, leading to improved user experiences and potentially freeing up human employees to handle more complex tasks and interactions.

Out-of-state projects add another layer of complexity.

A good friend of mine, managed a similar transaction last year: he merged several single-family homes around Florida and exchanged them for a mid-size apartment complex in Chicago.

In my experience, a suit for specific enforcement of a real estate purchase contract is not particularly complex or fact intensive that would lead to extensive time needed for discovery. 

Does the condo complex have rent to own percentage restrictions (they all do, you want to know what percentage is allowed and what percentage it is at now)?
