Just curious what the costs would range (assuming no asbestos or other major environmental hazard)?

Look at how differently every real estate buyer does inspections, environmental due diligence, title due diligence etc. 

Dig into to this and make sure there isn't something going one like a environmental cleanup is required or some other reason why no one was willing to bid on this property.

Project is entitled with planning department and demo of building is okay as it is not historic and no issues with state environmental.

If you need to treat for pets or pests, do it in as environmentally-friendly application as possible.  

However the property is located close an impacted water body and over the course of the next 2 to 3 years there is a study being conducted to determine if the septic systems in my area are contributing to the pollution of the river.

There are several types of inspectors that specialize in particularareas, for example: structural engineers; geotechnical engineers, roofers, plumbers, sewerline scopes, electricians, HVAC contractors; environmental professionals; industrialhygienists; surveyors; etc.

@Michael Hart  very common misnomer Real Estate can and does go to zero and actually goes negative.many ways.. look at blighted inner cities.. many properties have zero value.. environmental issues on a property.. etc... but generally speaking I hear ya.. but I think this is one thing that has led many investor to lose lots of money over the years.. thinking that RE is a SURE thing and they can't lose... nothing can be farther from the truth.

@Henrick Sorenson any type of pollution policy would be offered by a Lloyd's of London insurance carrier.  

As part of the land purchase, I feel it would be best to present all of the revenue generation options upfront for each property before starting geological, environmental, and civil surveys.I would appreciate any insight on creating value post-purchase, identifying suitable revenue options, forecasting, estimation of potential returns during development, key team members to add (engineers, surveyors, etc.), and deal structuring (I am raising funds for the purchase so insight into owner-financing options, etc. would be great).Thanks for replying,Ryan
