Is Dubai property a bubble? What the UBS index says about Dubai, Frankfurt, Hong Kong and Singapore

“Is it too late to buy in Dubai?” is a question best answered with someone else’s method. The Swiss financial group UBS publishes an index of housing-market overheating in world cities several times a year, and it provides a frame of reference.

How Dubai is rated

The index placed Dubai in fair-value territory. The assessment gave these reasons:

• house prices fell for seven years in a row and recovery only began in 2021, so the risk score over the decade dropped substantially;
• rents grew faster than house prices — over the four quarters covered, rents rose by about 20%;
• adjusted for inflation, housing remained roughly a quarter below the level reached in 2014;
• immigration was boosted by visa programmes, the absence of income tax and the early lifting of Covid restrictions.

The caveats in the same assessment were just as useful: the market is cyclical and prone to overbuilding, and rising mortgage rates together with continued expansion of supply, especially of apartments, limit the potential for price growth.

For comparison — cities in the risk zone

• Frankfurt. Long near the top of the list of the most overheated markets. More expensive mortgages cut the rise short: real prices fell by almost a fifth from their late-2021 peak, and letting out a purchased home became a loss-making exercise.
• Hong Kong. Between 2003 and 2018 real prices almost quadrupled while incomes stagnated; a skilled worker would need more than twenty years of average annual income to afford a 60 m² flat. The city sat at bubble level for years.
• Singapore. Real prices rose by 15%, but rents rose by about 40% over the same period, which held the rating in check. One detail stands out: foreigners pay a stamp duty that can raise the cost of a purchase by up to 65% — the highest rate among the world’s financial centres.

A practical benchmark

A simple rule follows from this logic: if a specific property pays back in under 15 years — that is, it yields more than about 6.7% a year — it deserves attention. This is not a guarantee but a filter: it screens out what is bought purely in the hope of price growth.
