How often are REIT dividends paid?

Could you please elaborate on the frequency of REIT dividend payments? Are they distributed quarterly, semi-annually, annually, or do they vary depending on the specific REIT? Understanding the payout schedule can help investors plan their cash Flow and evaluate the potential returns of investing in REITs. Additionally, is there any information about the stability of these dividends over time, and are there any factors that might impact their payment?
