That will dramatically change what financing abilities you have at your disposal. 

So I decided to cut down that tree and dispose of it.

I bought 3 cheap and unloved homes during the 2008-2016 economic problem, but now that that problem had been disposed and good times have returned I'm stuck!

You could record an option if seller chose to wait to dispose after tenant moves to kill your competition.I can't answer your sub2 question without know all about debt. 

I can't believe people would just dispose of them in the walls like that.

Oh, and if I own it, I have a wider range of how to dispose.

BTW, if he disposes of property for a less than his basis, he won't pay tax.

We have informed the tenant we will dispose of his belongings at end of the waiting period.  

The extra year can be used to dispose house if they don't exercise option.

An advantage you have is with proper documentation of the rent owed and damages getting you a judgment in civilian court, you can send the paperwork to the Defense Finance Accounting Service to process a garnishment against his wages where 25% of his "disposable" income will be garnished monthly until you get paid back.
