That kind of depends on how you run things. Sure, owning the house you grow in is really convenient. But when the feds take your house, whether you still owe $100,000+ on it, or it's completely payed off. It sucks to lose that much capital, or too trash your credit that badly. Professional commercial growers rent houses with a fake name, minimize their contact with the property and if there's ever trouble you're only ditching your deposit, equipment and last harvest. Keep your equipment value low; and have short harvest intervals... that way what you're losing is less than what bail would be. But that's just for people talking about growing commercially. If anyone's growing at their house... I hope they're not moving too much weight.
Any grower who buys a house to grow in, and gets it seized.... well they are pretty stupid.
The bank/lender has the FIRST lien on that property no matter what when it comes to seizure. As long as the property has little equity, they wont seize it if they find 1000 kilos of coke in it. LEO has to pay the bank off, sell it, and make a profit.
This holds true with anything with titles and liens like homes, cars, boats etc.
So make sure all your stuff has a lien, and little equity. Easier with homes.
