This guide is designed to help you ask better questions, organise evidence and know when professional or official confirmation is needed. Requirements and individual circumstances can change, so use the dated official sources at the end.
1. Prepare the property and document file
A smoother tenancy begins before the advert is published.
Confirm ownership or management authority, permitted use, energy certificate, insurance, safety and the condition of services and appliances. Resolve material defects and decide exactly what is included.
Build a property file containing current records, appliance information, maintenance contacts, meter details, condominium rules where relevant and a photo inventory. Define who can approve repairs and how urgent issues will be handled.
- Validate the energy certificate
- Test safety equipment and essential services
- Create an inventory before marketing
2. Advertise clearly and screen consistently
Good information reduces unsuitable enquiries and disputes.
State the rent, deposit, advance rent, available date, duration, furniture, utilities, pets, parking, accessibility and any objective qualification requirements. Use recent photographs that accurately represent the property.
Ask every applicant for the same necessary information, explain why it is needed, limit access and retention, and avoid criteria that could be unfair or discriminatory. Assess affordability and references consistently rather than making informal assumptions.
Tenant information can be sensitive. Collect only what is necessary for a defined purpose and manage it with appropriate consent, access and retention controls.
3. Contract, register and receipt
The written and tax records should match the tenancy agreed.
Use a written contract identifying the parties, property, use, dates, duration, rent, payment, deposit, advance amounts, responsibilities, inventory, communication details, renewal and notice. Obtain appropriate legal and tax advice for the specific arrangement.
Communicate the contract and relevant changes to the Tax Authority within the applicable process and deadlines, and issue electronic rent receipts where required. Keep evidence of rent, deposits, expenses and communications.
- Attach the signed inventory
- Record every sum by its purpose
- Keep tax and tenancy records aligned
4. Handover and manage predictably
A responsive system protects the home and the relationship.
Complete a signed move-in inspection with photographs, meter readings, keys, manuals and emergency contacts. Give the tenant a clear route for reporting repairs and acknowledge issues promptly.
Schedule lawful access with proper communication, document works and keep decisions in one record. Before the tenancy ends, explain the checkout process, inspection, final meters, key return and how any deposit reconciliation will be evidenced.
- Use a repair-priority system
- Retain invoices and access records
- Document checkout deductions with evidence
