My business partner and I tried RE our way and although we weren’t totally failing we weren’t creating the success we wanted. 

You:live on a different continentare young have no credithave no real estate experienceare in a class of investors that as @Jay Hinrichs pointed out is highly targeted in scamsIf 10 people like you attempted this, 9 would fail.

I'm not sure if its fear of failing again, if you want to call it that, or just the difficulty of starting over. 

This is an area many new to the strategy fail to include.  

That's pretty strong evidence they created a fantasy to escape your lease and no-pet policy.My response would be simple:Dear Tenant,You failed to provide any evidence of an unsafe situation in the home.

You’re looking for diversity; people will leave when they lose their jobs if the entire economy in an area is centered around one or two industries.Small businesses and any kind of services will either move away or fail if the biggest employers are not hiring.

Then I either get better than average rents or I'll sell it.First I repair/replace things, if needed, that cause more damage (to property or life) if they fail, roof, water heater, plumbing & electrical... anything health and safety related. 

I do charge $50 extra per hour if a guests fails to leave the place on time and the cleaning crew is waiting outside and I have a reservation back to back.

Should your tenants pay late fees because Hosted Web Application infrastructure failed?

With that, even if you fail miserably (Not that you ever will), you can easily dust yourself off and jump into other ventures.
