What is Monte Carlo Simulation?
Вычислительный метод, запускающий тысячи рандомизированных сценариев для моделирования диапазона возможных результатов инвестиции и количественной оценки вероятности исходов.
Description
Monte Carlo simulation is a quantitative risk analysis technique that uses random sampling to generate thousands of possible outcomes for an investment. Instead of relying on a single forecast, it varies key inputs, rental growth, vacancy rates, exit cap rates, interest rates, across their probable ranges and produces a distribution of outcomes. This shows the likelihood of achieving target returns and the probability of adverse scenarios.
For a Dubai property investment, a Monte Carlo simulation might vary rental growth (2%-8%), vacancy (0%-15%), exit cap rate (5%-8%), and interest rate (4%-7%) across 10,000 scenarios. The output might show a median IRR of 12% with a 90% confidence interval of 7%-18%, and a 5% probability of negative returns. This probabilistic approach is far more informative than a single-point estimate.
How to interpret
Monte Carlo simulation replaces single-point forecasts with probability distributions, which is a more honest representation of how uncertain the future is. Rather than saying "this investment will return 12%", a properly run simulation says "there is a 60% probability the return falls between 8% and 16%". This range gives investors a much clearer picture of what they are actually accepting when they commit capital.
The inputs to a Monte Carlo model are as important as the model itself. Garbage in, garbage out: if the range of assumptions used for rental growth or vacancy is too optimistic, the simulation will show a misleadingly positive outcome distribution. Use conservative central estimates and wide ranges to capture true uncertainty.

Monte Carlo simulation is most commonly used by institutional investors and fund managers evaluating Dubai property portfolios where multiple interdependent variables drive outcomes. The technique is less common among individual retail investors, but the underlying discipline, stress-testing key assumptions against a range of scenarios, is accessible and valuable at any investment scale.
Dubai's market volatility history, with price swings of 50%+ in the 2008-2011 downturn, provides useful data for calibrating the tail risk distributions in Monte Carlo models. Investors who use only post-2020 data to inform their assumption ranges are systematically understating downside risk. Including longer historical data, particularly through full market cycles, produces more strong risk distributions.
