I'm wondering if anyone has been involved in buying a property that has been "cleaned up" by a state department of environmental management.

Yes, it is more management, but also well worth the increased per sq ft income and the social good of impact investing by creating community, affordable housing, and an environmentally friendly real estate solution.

Verify if it’s on city water/sewer, if it has any liens against it, of the phase 1 environmental survey comes back ok, how the utilities are, if the profit and loss statements are accurate, and anything else that the park has.  

And, this was handled directly with the subcontractor (meaning, no GC markup and I take care of the legwork involved with permits and utilities).I would guess the prices vary significantly based on location - labor costs and environmental regulations would have a huge impact on this. 

Be sure to understand the age and condition of the major components, roof, HVAC, windows, kitchens, bathrooms and how soon you will have to replace them.

You will most likely need an environmental report, and the appraisal is going to be more costly too.The larger title companies like First American and Fidelity have rate calculators that can give you an idea of closing costs, but I'm not sure if they support commercial properties.

Unless Buyer exercises the right to terminate granted herein, Buyer accepts the physical condition of the Property and any violation of governmental, building, environmental, and safety codes, restrictions, or requirements, but subject to Seller’s continuing AS IS Maintenance Requirement, and Buyer shall be responsible for any and all repairs and improvements required by Buyer’s lender. 

I am not an expert on this, but I heard of an older dentist office near me a while back that had some environmental issues.

Hardwood flooring only when it was originally there.My Rehabs include any major component that will not last past 5 years along with the usual cosmetics stuff. 

Any environmental issues with the building or land?
