Of course the worst case is actually getting lawyers involved and I wouldn't go that route I just wanted to make the basic contract law argument about the PoA's limitation. 

Lawyers, engineer, architect, expeditor, surveyors, etc pile on the fees quickly. 

One of our lawyers informed me that you have to issue a 28 day notice to vacate.  

Each exchange starts the clock again, and you lose the tax benefit if you do not hold and rent out each property for enough time to satisfy the rules.6) I used a 1031 exchange lawyer in the city that I purchased in.

I have to get a lawyer there anyways and talk about the implication of him doing this without notifying me and redo the loan paperwork .

3- Feel free to tag someone who is well versed in DC zoning here whether this person is an agent or a lawyer. 

Anyways I sent him a notice through a lawyer about this issue stating that he is breaking the lease.

I had a conversation with a Probate/Estate lawyer and he suggested the following but what he said doesn't quite add up to what I have read so I want to see if I am just not understanding or if I am getting bad gouge.Advice was to create WY LLC that owns all properties, that is then "owned" by a land trust for additional anonymity, that the beneficiary is a regular Trust that owns everything else in my name.

Otherwise, you could also provide prevention recommendations somewhere on the lease that includes what you've mentioned above.Assuming you don't have a lawyer to help with your rental agreement you can find some sample clauses on a site such as Law Insider.

I don’t believe a tenant can stay forever, and I can cover the extra payments and lawyer fees for up to two years for the tenant who will be harder to remove.
