Most UAE banks work within an overall debt-burden ratio cap of 50% of income across all your combined obligations, but that upper limit isn't the same as a "safe" or comfortable target for a single loan's EMI. Many financial advisors suggest keeping any one loan's EMI closer to 20-30% of your monthly income, leaving room for other existing debt, unexpected expenses, and the possibility of taking on further financing later without breaching the overall cap.
