In my future real estate plans, I want to make my flips as environmentally friendly as possible, and that includes smart technologies (likes Nest thermostats and smoke alarms).

Municipal liens, property tax liens, environmental liens and federal tax liens are examples of exceptions.

There can be extremely expensive costs involved for buyers in meeting environmental regulations, etc.

If you can get that much, it is a factor, but have you had the building inspected (environmental, condition) to make sure you have good expense data?

The other major risks I have heard is environmental and IRS tax liens.

4 Due Diligence cost - $16,000 seems low -- did it include --an appraisal, phase I Environmental , Engineering Inspection Report and Survey ?

I'd like to see the original vote stand for many reasons -- safety, quiet, environmental, and fewer rules needed, which we seem to have a problem enforcing.

You can go here... http://www.mass.gov/eohhs/gov/departments/dph/programs/environmental-health/exposure-topics/lead/ and on the right hand side of the screen there are "related links" with "Database of Lead Inspections for Homes in Mass" as a choice.

One for general structural and one for phase 1 environmental?

There was a leaking underground oil tank issue that had to be resolved (there is another thread on that....) and I'm waiting for the "all clear" from the State Environmental Office.
