Hello and welcome to Bigger Pockets! And, welcome to the club of real estate investors in Dubai ☺
First about Bigger Pockets.. this is an awesome place to network with other investors and professionals that can help you in your real estate career. But that's just one little part.
Not sure if you have checked out the other contents yet. If not, I encourage you to read the blogs, check out the forum posts, set up some keyword alerts like "Dubai", "Sharjah", etc. and your interests. This will make sure you are notified as soon as someone posts with those words. By the way that's the way I was alerted about your post.
Also listen to the podcasts. There are over 150 hours of amazing interviews with people who have done what we are learning how to do.
Then there is the Ask BP section which includes some great Q&As. There are many books available here too. Check out the suggestions at biggerpockets.com/books
Now a little about investing in the UAE. The laws in Sharjah about rent locking for 3 years makes it less attractive to me personally, but again I can't say much because I haven't studied the emirate yet. I can guide you about Dubai and especially International City. It's a low hanging fruit and the returns beat the country average.
Feel free to ask questions. I'll be add whatever value I can.
Good luck!
