At the initial raid they will take anything the see grow related, lights, bongs, weed, EVERY SCRAP OF PAPER!!!!!, possibly computers, any cash, possibly render the main power feed inoperable if they feel someone is going to get the bright idea to set up shop behind the police tape (yes it happens) they usually leave some weed behind..after all your going to need if you post bail and see what they have done.
As for seizing of assets, this should happen after you are sentenced and proven guilty. Most states dictate that they need proof that you have bought assets from drug money, however this is not always the case....take for example a car transporting drugs....the judge may see it as a TOOL used to commit the crime. As where the police impound the car for the time being until sentencing. Its is a stretch that your home will be treated in the same fashion. I think being assed out of a place to live will be the least of your concerns.
seizing of assets is funding for law enforcement toys and programs. They like to seize stuff....after all who doesn't like free $ to pay for stuff. mortgage paid off...you bet your ass they will fight tooth and nail for it. less hoops to jump through. If your home is worth 140,000 and the bank still owns a majority of the note they will probably look for bigger and better fish to fry. The county you live in really determines how bad they are going to come after you or if the even bother that much. The county I live in has a major hardon for seizing shit. There are some websites that have statistical data of $ and property seized by county. you can come to your own conclusion based on other data from arrests. Dig dig dig far into public records even have a sit down with a lawyer. The ideal situation would be to have as little ownership of the house as possible. Borrow against the house, and hide that money well. After all your paying interest.....but if your worried that much....remember money does grow on trees.............literally.
Now I know a friends father that got popped for a MAJOR meth manufacturing and distro that was found guilty. The property was paid for free and clear however the property was in such distress that the courts did not bother. This was in a southern state, in a very rural county...they basically looked and said we get more money from taxes. The friend and me went to rehab the home to rent out while the father was incarcerated...we waited till all legal preceding were done before we could get to work....we just let all the tweakers run a muck till everything was over....was fun...found a mobile meth lab. We chased alot of them away with bats and guns. Glad we had brought alot of muscle.
Laws are different everywhere so do your homework...it will pay off.
