Property and lender guide

Unusual property home loans

Possibly. Company title, stratum title, several dwellings, mixed use or an unusual lease can change the deposit and the lenders available, even when your income is strong.

Client story

How can one property detail change the loan?

Miles had more than $3m of property supporting an existing loan of about $1.77m. The numbers looked strong until the valuer marked a minor commercial component.

In that past application, the bank applied a 70% limit and removed one business property from the properties backing the loan. The bank would lend roughly $2.5m.

Our team changed which properties backed which loans and moved one property into its own application. That recovered about $300k, taking the available lending to roughly $2.8m.

  • Before restructuring

    About $2.5m

    Available lending under the original assessment.

  • After restructuring

    About $2.8m

    About $300k recovered by changing which properties backed which loans.

The point is not that every bank uses the same limit. It is that one property classification can change the available equity before the income assessment changes at all.

What will you actually own?

  • A strata lot

    You buy a separately titled lot within a scheme, with associated rights and responsibilities for common property.

  • Company shares

    The company owns the property. Your shares give occupancy rights under its governing documents; you are not buying an ordinary strata lot.

  • A leasehold interest

    Your rights depend on the lease, its remaining term and its conditions. The lender must be able to accept that interest as security.

For company title, ask your solicitor to check the constitution and any approval needed to transfer shares, rent the home or alter it. Revenue NSW explains the ownership structure.

Why can company title require a larger deposit?

Company title usually means shares in a company carry the right to occupy a particular part of a building. That is different from owning an ordinary registered strata lot. Your solicitor should confirm the legal position from the company and title documents.

For the loan, I separate acceptance from the maximum loan percentage. Current policies include refusals, 80% options without lenders mortgage insurance and more conditional options. The development size, company setup, location and valuation can all matter.

Example: a $700k unit with an 80% loan limit

  • Purchase price

    $700k
  • 90% loan first expected

    $630k
  • 80% bank limit

    $560k
  • Company and occupancy
    Constitution, ASIC company search, shares and occupancy rights.
  • Property and loan
    Number of units, address, valuation and whether mortgage insurance is available.

I looked at 4 lenders with published company-title rules. They fall into 2 broad groups. The dwelling count is the figure that decides which group may apply.

Stratum title is not the same as strata title

The similar name creates false starts. Stratum title can divide a building by level or section and rely on easements or service arrangements. I would not let a standard-unit pre-approval stand in for a title check.

Current policies range from standard treatment to state-specific acceptance, an 80% cap without mortgage insurance or refusal. The title search, plan, state, valuation and shared-service documents decide which row is relevant.

  • Title question

    Does the title and plan identify a stratum estate and the rights needed to access and use the property?

  • Property question

    Can the property be valued and sold as acceptable residential security under the selected policy?

  • Loan question

    Does the required loan percentage fit the title rule, location and mortgage-insurance position?

Will the lease last beyond the loan?

ACT residential Crown leasehold is commonly addressed in lender policy. A lease elsewhere can follow a different rule. I would first identify the lessor, location, unexpired term, permitted use, assignment conditions and any performance obligations.

Example: a 25 year lease and a 30 year loan

  • Lease remaining

    25 years
  • Requested term

    30 years
  • Lease ends before the loan

    5 years early

The lease would expire 5 years before the requested loan term. That term cannot work as proposed. A shorter term still needs to satisfy the selected lender's additional buffer and the lease conditions.

Current comparison: published additional buffers in the policies reviewed range from 5 to 20 years beyond loan maturity. The precise lender and lease type matter.

Do not read a positive buffer as approval. Some policies distinguish ACT Crown leasehold from non-ACT Crown leases, private leases, snowfields leases and other specialist arrangements.

Leasehold land is different from a residential park site

A manufactured home in a residential park can involve owning the home while renting the site. That is different from the Crown leasehold arrangements discussed above. Check the site agreement and the finance available for the exact ownership structure. The Queensland site agreement guide explains rent, utilities and other terms to review.

How do multiple dwellings change the assessment?

A listing may describe a house, cottage and granny flat as 3 dwellings. First I confirm how many are legal, approved, self-contained and included in the valuation.

Example: a $900k property with 3 approved dwellings

  • Accepted value

    $900k
  • Example 70% path

    $630k
  • Contribution before costs

    $270k

Some current residential policies can consider 3 established dwellings but reduce the loan percentage or require a credit exception. Other policies stop at 2.

If the same borrower plans to build the 3 dwellings, the construction limit can be tighter. The established-security rule does not answer progress payments, builder requirements or the as-if-complete valuation.

  • Approval and completion
    Approvals, existing versus proposed dwellings, and whether construction is involved.
  • Use and valuation
    Owner-occupied or investment use, rent relied on, valuation basis and saleability as one title.

If building is involved, use the construction financing guide as a separate decision. A lender accepting the finished security does not automatically mean it will fund the build.

Dual key, duplex or granny flat: check the title

A listing label does not establish separate ownership. Check the approved layout, number of legal dwellings and registered titles. If several dwellings share one title, do not plan on selling or refinancing each dwelling separately without checking the legal and lender requirements.

For apartment size and building rules, see the apartment home loan guide. If you plan to add a dwelling, start with the approvals and construction finance process.

Mixed use depends on what the valuer is being asked to value

A home office is different from a shop and residence on one title. A separately titled home above a shop is different again. The words "mixed use" do not settle the loan.

  • Title and planning
    Title, zoning and approved use.
  • Occupation and valuation
    Actual use, valuation basis, commercial floor area, and any lease or management rights.
  • Residential use in mixed zoning

    Some current policies can use residential treatment where occupation is permitted and a residential valuation is returned.

  • Residence above a shop on its own title

    Some policies may consider it where the separate title, residential use and valuation fit. Others exclude homes above shops.

  • Residential and commercial use on one title

    Current positions range from a lower loan percentage with a full valuation to refusal or another assessment path.

  • Completed warehouse conversion

    Some current policies accept a legal residential conversion, while others exclude property converted from a previous commercial use.

Miles's case shows why I would read the valuation classification before arguing about the number. The 70% limit in his earlier application came from the minor-commercial-component classification, not a lower dollar valuation.

If the valuation wording appears wrong, separate a factual error from a correct policy warning. A wrong use, floor area or title fact may support a review. A correct mixed-use classification usually needs a lender whose rule fits, not a request to ignore it.

Use the bank valuation challenge guide if you already have the report.

An easement is not an automatic fixed loan limit

An easement can give another party a right to use part of the land for access, drainage, sewerage, electricity or another registered purpose. Your solicitor or conveyancer should explain what the dealing allows and whether it affects your plans for the property.

For the finance question, I check whether the easement affects how you can use the property, where you can build, its value or how easy it may be to sell later.

That does not mean every easement is fine. The title, building position, access, proposed work and valuer's view of use, value and future saleability can still change the answer.

For utility or access easements, our power lines and easements guide separates the title, measurement, building-permission and finance questions.

Which document will answer the lender's concern?

Choose the document group that matches the lender's concern:

  • Company title

    Contract, company constitution, ASIC company search, shares and occupancy rights, development details and any existing valuation.

  • Stratum title

    Title search, deposited plan, easements, shared-service arrangements and valuation.

  • Leasehold

    Complete lease, lessor, expiry, permitted use, assignment terms, performance conditions and proposed loan term.

  • Several dwellings

    Title, council approvals, plans, leases, valuation and a clear statement of which dwellings are complete or proposed.

  • Mixed use

    Title, zoning and approved use, floor plan, commercial floor area, leases, planning records and valuation wording.

  • Easement

    Title search, registered dealing, survey or site plan, building position, proposed work and any valuation comments.

Once the property classification is clear, I can compare the relevant current policy without turning an application into the first title check.
