99-Year Land Lease vs Renting Out a Granny Flat Yourself

By Buy My Backyard ·21 June 2026

Why the Distinction Matters

When homeowners first hear about the Buy My Backyard model, the most common initial question is: "What's the difference between this and just building a granny flat and renting it out myself?"

It's a fair question. Both options put a secondary dwelling on your land. But who pays for it, who gets paid, who carries the risk and who does the work are fundamentally different.

Option 1: Build It Yourself and Be a Landlord

If you build a granny flat and rent it out yourself, the dwelling is yours and so is the tenancy, which is governed by the Residential Tenancies Act in your state. Key characteristics:

  • Build cost: You fund design, approvals and construction — from savings or borrowing
  • What you receive: Rent from tenants over time, less your costs
  • Term: Fixed-term (6 or 12 months) or periodic tenancies
  • Vacancy risk: Yours — rent stops between tenancies
  • Maintenance: Yours
  • Control: High — you can use, re-let or redevelop the dwelling as you choose
  • Legislation: Residential Tenancies Act (state-specific)

The Practical Reality of Being a Landlord

As a landlord renting out a granny flat, you can expect:

  • Upfront build and approval costs, and possibly loan repayments
  • Tenant turnover and vacancy periods between tenancies
  • Active management — advertising, screening, inspections and renewals (or a property manager's fees)
  • Repairs, maintenance and compliance obligations
  • Market rent fluctuations — rents can fall as well as rise
  • Legislative changes that can shift the balance between landlord and tenant rights

Granny flats commonly rent in most metro markets, and being a landlord can work well for people who have the capital, want the dwelling as their own asset and are comfortable with the responsibilities. It's real work and real risk, though, not a hands-off arrangement.

Option 2: Lease the Land to Buy My Backyard

Under our model, you grant Buy My Backyard a 99-year lease over an agreed portion of your backyard. Key characteristics:

  • Build cost: $0 — we fund design, approvals and construction
  • What you receive: A one-off lump sum, paid up front when the lease is signed
  • Term: 99 years, documented and registered on your title
  • Vacancy risk: Ours
  • Maintenance: Ours
  • Dwelling: Built, owned and managed by Buy My Backyard for the lease term
  • Rent: Paid by tenants to Buy My Backyard — you don't receive rent or ongoing payments

The Practical Reality of a 99-Year Land Lease

Under a 99-year land lease with Buy My Backyard:

  • You keep title to your whole property — it's not a subdivision or a sale
  • You're paid once, up front, and the money is yours outright
  • We find tenants, manage the dwelling and handle maintenance for the life of the lease
  • You have no landlord duties and carry no vacancy or maintenance risk
  • The lease is registered on your title and continues if you sell the property

On property sale Dwelling and tenancy go with the sale Lease stays with the land; your lump sum is already yours
Tax implications Rent is assessable; deductions may apply Seek tax advice on the lump sum

Which Is Better?

It depends on what you want.

Building and renting yourself may suit you if you have the capital or borrowing capacity, want to own the dwelling outright, want to receive the rent and are comfortable being a landlord over the long term.

Leasing the land to Buy My Backyard may suit you if you'd rather have cash now, don't want to fund a build or take on debt, and don't want tenants, maintenance or vacancy risk.

Which Is Better for Flexibility?

If you want maximum flexibility — the ability to use the space yourself, end a tenancy or redevelop freely — building and renting yourself gives you more control.

A 99-year lease is, by design, a long-term commitment over the leased portion. Ending it early generally requires the agreement of both parties or a specific breach provision. That's the trade-off for receiving a lump sum up front with no cost and no landlord responsibilities.

Do I Need a Lawyer for a 99-Year Lease?

Yes — and we actively encourage it. A 99-year land lease is a significant legal document. Before executing the lease, you should have it reviewed by an independent solicitor who can advise on:

  • Your rights and obligations as the landowner
  • Buy My Backyard's rights and obligations as lessee
  • The defined portion of land covered by the lease
  • Termination events and processes
  • Registration of the lease on your title
  • Implications for your mortgage — your lender's consent may be required
  • State-specific legislative requirements

Buy My Backyard will provide you with a draft lease well in advance of execution and will pause the process to allow adequate time for legal review.
