Do not spend another dime on this property until that question is answered.It could be something as simple as an outstanding fine for an overgrown lawn or as disastrous as environmental contamination leaching into a public water supply.  

As I continued to research the property I found that the adjacent property was marked as a place with environmental interest but just because it’s marked it doesn’t mean it is a violation or dangerous.

Those centers can sit for awhile as you had overbuilding and now a population decline and a small list of tenants wanting to enter that market or expand current foot print in a declining market.
