They require too much action from the tenants.

I think I'm understanding it is about obtaining a solid grasp on these various aspects, then creating action in the right way.  

I am a longtime newbie finally taking action. 

Also I've read that it's not advantageous to start a foreclosure action when there is a mortgage ahead of you.

Of course, if it turns out that they are growing illegal plants, that's another issue altogether.You ought to at least get a cut of that action!!!

It certainly takes education & action & a mentor ( or a dozen) but now is most certainly the time to jump in.

You are familiar with the saying "actions speak louder than words" I take it?

Another is a pre-foreclosure purchase, where the seller is highly motivated and is under undue pressure to enter into a sale agreement.A neighbor offers a price to a property at a premium so that the buyer can control the property next door;A seller does not disclose deficiencies about the property, physical or in title, or even of pending actions (like government re-zoning actions).A buyer does not disclose to a seller of an existing permissible higher and better use for the property.

Why is there any benefit to taking this course of action?

My fear of the 2008 government actions, specifically the enactment of the Housing and Economic Recovery Act (aka "HERA") in July and the Emergency Economic Stabilization Act (aka "EESA") in October, is that we are replacing our "Capitalist" system with a "Socialist" system and jeopardizing the principles that made this country great.
