Arlington officials originally projected land acquisition costs at $60 million. Because of property owner disputes (17 of 62 are still outstanding), the actual cost is $80
billion million, which doubles the original estimate based on local tax appraisal figures. That's some huge inflation that should be taken account as the Metro Budget office ostensibly projects local costs of $75 million in offers to Nashville property owners.
Fortunately for Arlington, there is a contractual cap that requires the pro football club to assume increasing costs of outstanding disputes in the future. In a convention center build here in Nashville I don't see a third party present to absorb skyrocketing costs.
