When a contract holder can return home, any removal and electricians / plumbers required will need to be arranged with the contract holder.
The rent account for the decant property will need to be voided and the property passed for the void process to be completed. Ideally, the property should be advertised in advance, once an expected decant end date is known.
Considerations
For short decant periods, a retirement scheme guest room may be sufficient, however the contract holder would need to meet the criteria of the scheme and residents of the scheme would need to be consulted in advance.
