A sign of the times. When we have to publish a registry of where the former drug houses have been. Well there is a very good reason for this. It is toxic and can cause brain damage to young children and severe health problems for adults.
The registry is not used by all cities which makes it less useful than if it was mandatory. The other problem with registry...how do you get a home removed from the registry once a home is cleaned up or repaired? There is no provision for removal from the registry as of this posting.
So the obvious issue is being on the registry could certainly lower the value of the homes around the Meth home and could long term affect the value of a repaired Meth home.
One of the problems with buying a Meth house is the insulation is affected in most cases as well. You may not be able to see the problems with a visual inspection. Go to the link I have provided and take a look at the issues created by these intrusions into communities causes by the people that prey on our society with lethal drugs.
This web site registry was created in December 2006 as a National Registry by city. Not all cities participate but some cities will take you literally hours to cruise through to see if the home you want to buy or show is on the registry.
Checking the registry is not a sure fire way to find out the facts...always chat with the neighbors...they will know too!
I hope this helps you in your quest to find a great "safe" home of your dreams for you and your family.
