Another factor that works well with US investors is that the local currently AED (Dihram) is pegged to the USD at 3.67~ AED per 1 USD.For long term rentals, its on average 5-8% after the “Service Charge” reduction.

I agree that these are more important factors.

I planned for it financially, but it's a headache for sure. your rent is too high if they are sitting vacant.. there is more inventory than butts to put in them.. therefore competition for the few qualified tenants this will cause rents to go DOWN.. if a property is not rented in 2 to 4 weeks your rent is too high .. this is one of the major risk factors that many dont see when buying in a subdivision of group of ALL new rentals..

There are two types of appreciation to consider:1.Market Appreciation: Rising property values driven by external factors like economic growth, demand, or market conditions.

I found out those two factors still couldn't guarantee they pay their rents on time. 

Will depend on several factors like the type of property, type of tenants, your risk tolerance, other assets you own, your estate planning, laws where the property is located, etc.

@Nik Farooqui You are correct in that GC licensing is never a requirement but it is more of a "silent factor" that can make a lender more comfortable lending hard money and thus the approval and loan process easier.

If think you'll have capital expenses I'd factor those costs in. 

There are a lot of factors that go into this and a lot of levers to pull.If none of this works and the goal of the new purchase is to househack that property into an investment property, you may be able to use a DSCR loan to buy the new property as an outright investment property.

Some investors make it work by targeting less saturated areas nearby, but a lot of folks find more affordable markets out of state, which can make this strategy more feasible.Capital needs can vary quite a bit depending on factors like partnering, financing options, and property types.
