FW is (in my opinion) always going to be a safe place to invest in. 5. a real estate agent can help 

CAn some one shed me some lights on how foreigner can invest in Duabi, which firms that I can go through, who are reliable and keep my investment safe and able to get some decent returns, and what are the tax consequences for earning potential from outside the country?

Your not correct under many different circumstances.First property tax is 1.1% (fairly safe) with 2% annual increase (prop 13).Next expenses include a lot more than property tax and interest. 

That is a safe harbor from the IRS with a couple of caveats. 

Hi @Zhong Zhang I have used vacancy hacks over the years to get personal properties under 1% when turning tenants over. 3% increase depends on renewing or getting new tenants, when renewing tenants that's  a safe amount. 

Maryland has more likely (but still long shot) criteria.But, it is not safe to assume you won't be sued since the US has about 30 million civil lawsuits pending as I type this.And, it is against public policy to insure intentional torts.

We found that two key factors significantly helped us succeed with our short-term rental (STR): using NightlyPricer instead of AirDNA and opting for Safely Insurance.NightlyPricer: Rather than relying on AirDNA, we chose Nightly Pricer, which provides more dynamic, real-time adjustments based on demand, local events, and market trends.

Bought it as a safe bet thinking it would do roughly $35k annually in short term rents.

Feel free to reach out directly if you'd like to dig deeper into the chaos I've immersed myself in over the last 10 years or so.Cheers and drive safe

I know that the general guidance is that emergency funds aren't to be invested, but given our financial security and the fact that we already have a personal e-fund in a safe, non-volatile location, would it still be crazy/unwise to invest this 15k in an S&P500 index fund in a brokerage?
