Regarding the overall Dubai market:
-Everyone expected 2020 to be tough, with so much supply coming online. Some supply might now slip to future years, which unfortunately would prolong the pain. I would much prefer 2020 to be the year where everything gets dumped on the market and we hit bottom so I hope that as much as possible is completed in 2020.
-There are a lot of investors waiting to see the bottom, they've been holding fire and staying on the sidelines waiting for a clear sign. This is how all markets work when they are going down, most people wait to buy until they see some upswing. Bottom-catchers are a smaller percentage of investors.
-The supply for 2023, 2024 was already pretty light. New launches had dried up in the 2nd half of 2019 and are now totally dead. The launches that have occurred are small buildings with less units (compare Burj Crown to Address Fountain Views as an example). If construction continues roughly on schedule, then there will be a period in a few years where there is very little new supply.
-The government has intervened in the Real Estate market. The boom and bust model is not very attractive to them. Remember that everything in Dubai is new. Their handling of the economy included. Burning investors over and over is not attractive or long-term thinking. Cancelled projects and megaprojecs is not cool. I predict that once we do hit bottom, the government will try to manage the market to behave like most developed markets in the world: predictable and consistent price growth of around 5% per year over the long-term. But managed even better because they have much more control than most governments.
-That would mean no more flooding the market with launches in the good times, and no more cancelling projects because you got over-stretched.
I already invested last year and so was early. And I actually want to use the apartment when it's ready (Elie Saab). So I do have a vested interest. But I like to think I did apply some logical thinking before making the decision to buy

If anyone has a different opinion of how things will go, I'd be interested to hear.
