Get some of your own experience the hard way, with your own money, then you'll understand all of the little things in your proposal that are turn offs to those who already possess credit, money and experience. 

I'm sure the landlord would have received notice of foreclosure before the bank actually took possession of the property and therefore the landlord would be in violation of the lease.

I cannot see any records via the registry of deeds where the mortgage company challenged the order, am I to assume that the government is now in possession of the property?

Hi Diego, if they stop paying rent you can still evict them and get a Writ of Possession.

Because I couldn't buy the property, I filed for Adverse Possession.  

It depends on if the property has already been auctioned publicly at the county site, or if the bank has already regained possession of the property.  

I read somewhere that the new thing for ownership is to take possession in a trust as opposed to an LLC because banks and financial institutions view a trust as an individual and not a business and will offer faster and better financing to you and whoever your buyer is in the future.

In my area once you have been granted possession and all the additional paperwork has been filed .

The security deposit must be accounted for within 21 calendar days of your getting possession and all deduction items on it backed up with repair receipt copies or rental agreement/lease violation fee deductions. 

You can have a really poorly written agreement but the buyer is in possession with a tenant, that should show any judge there was an intent to sell.
