I'm going to explain to the seller he needs to have an environmental test done to see if in fact the ground is contaminated.

I am looking for tips and suggestions how to effectively start this process and what key elements should I look for during this process.

You have no obligation and neither does the environmental company have, unless it is obvious that there is the scent and oily appearance, then I think the company has the obligation to report.  

Financing is one of the most credit elements of understanding in order to prevent mistakes in SFR investing.  

=============================Title Insurance Company is irrevocably committed to issue to buyer an owners title insurance policy covering the property with standard coverage customary in the state where property is located showing liability in the amount of the purchase price and showing insurable title to the property vested in buyer, subject only to the following(a) Title Insurance company standard exceptions(b) Liens for all current general and special real property taxes and assessments not yet due and payable(c) liens of supplemental taxes, if any assessed(d) any facts an accurate survey and/or a personal inspection of the property may disclose(e) the mortgage/deed of trust/deed to secure debt lien in connection with any buyer financing(f) any laws, regulations, ordinances (including but not limited to, zoning, building and environmental ) as to the use, occupancy, subdivision or improvement of the property adopted or imposed by any governmental body, or the effect of any non-compliance with or any violation thereof, including but not limited to, any disclosure an/or report required by ordinance(g) rights of existing tenants and/or occupants of the property (if any)(h) covenants, restrictions, easements and other matters that do not materially impair the value of the property or the use thereof(i) non-monetary encumbrances disclosed to buyer in writing prior to entering into this agreement (j) any other matter for which the title insurance company agrees to provide insurance at no additional cost to buyer===========================================================

At least from the buyers perspective to add a protective element.2) Moving on is sort of complicated depending on how your agreement was drawn up.

If there is slope on a lot that you are looking to buy, there may be an ECA (Environmentally Critical Area) or slide prone designation tagged onto the property.

It's location, weak inventory and the uniqueness of the elements of the property and the vision of the other bidders that drives the bidding war.

At that point there's an element of risk that goes into any purchase.

I think the cost for that is a reasonable element to consider in any changing of ownership of the home at this time.I'm not pursuing the idea of trying to become the owner of this property to pull off any lucrative accomplishment.
