The Monetary Authority of Singapore is doing consultations about simplifying the rules for REIT debt limits:

MAS proposes that a minimum ICR of 1.5 times apply to all REITs. Currently, the ICR requirement of 2.5 times is to be met only by REITs which intend to increase their aggregate leverage from 45% to 50%. To simplify the requirements, MAS proposes that a single aggregate leverage limit of 50% apply to all REITs going forward.
