Just encapsulate, don't disturb.

@James Wise, how come you had your disturbing reply?  

they do a drive by on their own.. put their offer in and only look at the house during the home inspection.. no one wants to disturb tenants..really good agents in those price points have buyers lined up that buy that way.. no way are they going to haul someone around and show them beat up house after beat up house..

If you lose your job, or quit, you have 30 days to find a new one or leave the country.Not saying it's not a great country (I've heard lots of good things) or that there aren't good aspects of the economy and political system, but it's well known that a major part of the reason the economy is so good there, and the reason there is so much new construction is that a decent percentage of the workforce are practically enslaved laborers brought into the country as indentured servants (given a little bit of money and then being forced to spend decades working for pennies to pay off their debts).There are several disturbing documentaries about Dubai worker exploitation and some very prominent human rights groups focused on Dubai these days.Here's a summary:http://en.wikipedia.org/wiki/Human_rights_in_Dubai

Tell tenants to call police anytime there is domestic disturbances or she is damaging property.

Now, in less than a year, there are 5 kids (the 5th baby arrived just few weeks ago) and 3 dogs, doing "dodos" everywhere, attacking us on our own property, tenants don't seem to work and it's hard to imagine how they make living (neither one of them seem to work), causing noise disturbance by loud inappropriate music every time we are in our back yard, etc... 

I imagine the worst: a neighbor who is trashy and keeps empty soda cans or water bottles on the lawn, toys strewn about, doesn't cut the grass, smokes, has excessive traffic, vicious dogs, unclean or untidy enough to attract and feed roaches, loud music that disturbs my tenant, or even maintenance like the roof or windows.

Of course things can occasionally go wrong like a loud/drunk guest disturbing other guests but people understand the risks associated in apartment style buildings to a degree.Our very first STR was a small mansion on the beach that also had a detached 2/1 with a pool between the units. 

The only thing I am hesitant about is that across the street, there is a property with a weird construction: a garage with a huge (metal) roof, which could be visually disturbing for some people.

"It's good" or "it's just hot outside" is not a satisfactory answer on how the unit is running.It is disturbing that the outside unit i.e. the condenser was replaced with a larger size but not the evaporator/air handler.
