I wouldn't do it again but I didn't loose the house or file bankruptcy either. 

We actually did recently create a Dropbox business account mainly to back up our Googledrive folders since those have all of the soft collateral files on all of our loans, as well as our corporate docs, agreements, etc.

To give them 100% protection file a mortgage and note 1st lien position.

That will help keep your personal things beyond the reach of others that file legality against your business.  

Many jurisdictions allow contiguous property owners to file a protest petition and stop you dead in your tracks unless you negotiate a deal.

Yes as noted by @Kyle Mccaw, your not going to agree to any other terms once the eviction action has been filed and process started,, unless your in the court room with a mediator.

They are going to be more expensive and you still have to file your taxes afterwards.

I believe there are sample estoppel agreements in the file place.

We file joint return. 

It's uploaded in the file place called Service Animal Form or something like that.
