Answer
The comparison is ambiguous: in some cases, renting in Uruguay is cheaper than in Belgrade; in others, it is more expensive than in Russia or about twice as expensive as the previous budget in Thailand. There is no single overall benchmark.
Rental prices depend on the city, neighbourhood, number of bedrooms, furnishings, lease term, and gastos comunes. It only makes sense to compare countries when the housing quality, location, and cost components are similar; otherwise, the conclusion is arbitrary.
For a move, it is more useful to calculate the full monthly cost scenario in Uruguay than to ask whether it is “expensive or cheap.” In addition to rent, include shared building expenses, electricity, gas, internet, a rental guarantee, an agency fee, and a contingency for seasonal bills, especially in winter. Only this kind of calculation is comparable between countries.
