If there was any prior use that could have caused environmental damage (leaking chemicals, buried wastes, etc,) you might want to have it checked out.

Avoid exotic, hard to care for plant materials, or plants that are highly susceptible to disease and/or insects.Consider elements of Crime Prevention Through Environmental Design CPTED.... google it to learn more.Here's an excerpt from our rental agreement, you may find helpful:LANDSCAPING/YARD CARE.Regular landscaping/yard care (mowing, edging, trimming, fertilizer, weed control) will be provided by _______________________.For all Tenants:a.Tenant agrees to keep yards, walkways, patios and decks clear and to keep premises free of junk and debris.b.Tenant accepts liability for all landscape damage and/or replacement of such, if caused by neglect, abuse or lack of water.c.Tenant may plant the beds adjacent to their dwelling to their liking, but only with those plants that are of appropriate size and type for the beds.All plants brought or caused to be brought to the property by Tenant will be cared for by Tenant.d.Tenant agrees not to cut or prune trees, hedges and shrubs.This will be Landlord’s responsibility.e.Tenant agrees to properly dispose of all plant debris and agrees to not leave such on the property.f.Landlord will consider special Tenant requests for planting and removal of plants, shrubbery and trees, but reserves the right to determine the make-up of the landscaping.For Tenants of single family homes only: a.Tenant agrees to mow, water, and keep the grass, lawn, flowers and shrubbery thereon in good order and condition, applying fertilizers and weed retardant as needed. b.If there is a failure of Tenant to keep the landscaping in good order and to follow these guidelines, Landlord reserves the right to hire a landscaping service at Tenant’s expense (after a 10-day notice to perform covenant).c.Landlord reserves the right to restore the landscaping to its initial condition, as it was at the time Tenant began occupancy, or if improved during Tenant’s occupancy, to the level of such improvement.

For me, solar has been a play of hopefully having a small environmental impact, and reducing my own energy costs.  

If the deal has some upside, it is clearly worth the spend for an environmental survey/engineering company for their opinion.

If the property is non-residential you should consider a Phase I Environmental Site Assessment to provide some potential liability protection associated with past uses such as oil tanks or use of solvents, etc.

Kind of unsettling to people that they watching for cops, junkies etc and now this guy comes out creates a hostile environment. Ant

The seller (bank) has contracted a company to complete an environmental assessment of the land.  

Oh, some violations, environmental, are not filed together with housing code violations, so you have to ask where to go to find them.2.

Don't forget about the environmental!

@Anthony SimboliMake sure to get a Phase 1 Environmental Site Assessment done (your lender will most likely require it anyway).
