We used Statewide Environmental Services LLC in Raritan NJ, they took care of everything.

Your surveyor can do the entire process, possibly with the support of a Civil and Architect if you get into more of the site plan and design components.

You'd just pay them for each of the components, then you'd have a performing rental. 

Check with Connecticut's Environmental Protection Agency. 

Crime prevention through environmental design is a hot topic these days and landscaping plays into that.  

The rule of thumb on here is $100-150/door especially with most deals having a financed component.

Has anyone ever required a Phase 1 environmental assessment as a contingency?  

Another option would be to develop a relationship with a home inspector and have them come to inspect the house, but instead of having a full inspection, rather just focus on the main components and structure and forego the written report and just take your own notes while walking around with the inspector.

They make the entire component work but there are so few of them that are actually reliable and most people don't know the right questions to ask them when they interview them so they get duped. 

Lots of components in play to help answer what is best, including your overall financials and goals.
