RealToken holders are only paid when rent is collected. If rent is not collected from the tenant, then there is no rent to send out to token holders.
However, in the event that a tenant does not pay rent, the property management company is also not paid for their services. The property management company is only paid for the months that there is a tenant in the property.
If a tenant is delinquent on their rent, they will be evicted from the property and replaced with a more creditworthy tenant.
