We have some meetings coming up in a couple days with lawyers and banks so hopefully it goes well.

Quote from @Chris Porter: Unfortunately I need to evict my tenants and I need a lawyer.

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 was given to understand that tenants/tenant lawyers can only sue someone they have done business with.

Have someone physically there to check on the property and partner with them, etc.I'm not a lawyer and this isn't legal advice, but foreigners can setup US business entities in the United States, and not have to be physically in the United States.

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

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.

We thought about hiring a lawyer but the legal fees were expected to be in the range of $10k to $15k and would have taken months (if not years).

Quote from @V.G Jason: I'd partner with a lawyer that can help put some contractual language on the downside of working with contractors and real estate agents.I'd also partner with a RE brokerage firm that clearly understands your goals. 

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