Finding the perfect property can be exciting, but not every home is easy to finance. Lenders view some dwellings as higher risk than others, which can affect how much you can borrow or whether a loan is approved at all. Understanding why certain properties attract more caution — and doing your homework before you sign a contract — can help you avoid unexpected finance problems. If you’re new to the process, our pre‑approval guide explains how to get ready to buy.
Lenders assess the property as well as the borrower. High‑density apartments, very small units, properties in flood or bushfire zones, remote or single‑industry towns, and dwellings with unusual titles or unapproved structures can all trigger caution. Banks may cap the number of loans they will approve in a single building, require bigger deposits or simply decline certain property types. Pre‑approval considers your finances, not the specific property, so a lender can still decline a loan after a valuation. To avoid surprises, check the title, size, location and condition of the property; obtain strata and building reports; research comparable sales and speak with your broker early.
Key Takeaways
- Lenders are cautious about high‑density apartments, tiny studios, rural properties and homes in flood or bushfire‑prone zones.
- Banks sometimes cap the number of mortgages in a single development and may require larger deposits for inner‑city apartments.
- Mining towns, single‑industry regions, retirement villages and student housing often require higher equity or may be declined.
- Unapproved structures, major defects and unusual titles can cause valuation shortfalls or render a property ineligible.
- Pre‑approval doesn’t guarantee that a lender will accept a particular property, so early checks and advice are essential.
Why the property itself can affect finance approval
When you take out a mortgage, the property acts as security for the loan. Lenders need to know that they can recover their money if you default, which is why they scrutinise the property itself. If a dwelling is hard to sell, expensive to insure or susceptible to significant price swings, it becomes a riskier proposition. Banks therefore adjust their policies based on property type, size, location and condition. In 2025, some lenders quietly capped the number of loans they would approve in certain high‑rise developments and required larger deposits for inner‑city units to manage exposure.

The kinds of properties that can attract more lender caution
Certain features frequently raise red flags for banks and mortgage insurers. High‑density apartments and very small units: lenders often have limits on how many apartments they will finance in one building. Studios under about 40 square metres are considered less marketable and may not meet lenders mortgage insurance criteria. Rural or remote properties: homes on large acreage or in isolated locations can be hard to value and sell. Properties over 50 hectares or far from services often require specialist lenders or higher equity. Mining towns and single‑industry regions: property values in towns reliant on a single industry can swing wildly. Some suburbs are on so‑called ‘no‑go’ lists and require significant deposits. Flood or bushfire‑prone areas: properties in high‑risk zones often have higher insurance costs and may be difficult to insure, which lenders factor into their risk assessment. Special‑purpose dwellings: retirement villages, student accommodation, hotel or serviced apartments, time‑share properties and other niche dwellings come with complex leases or restrictive usage clauses. Many lenders decline them or require very large deposits. Unapproved structures and major defects: extensions or renovations done without council approval can void insurance and reduce market value. Structural problems uncovered during inspections can lead to a lower valuation. Unusual titles: company share, stratum or leasehold titles can complicate ownership and resale, so not all lenders will finance them.
What buyers should check before making an offer
You don’t need to be a property expert to identify potential finance issues, but it helps to do some basic due diligence. Confirm the title and size: ensure the title is freehold or standard strata and that the floor area meets lender requirements. Company share or stratum titles and tiny studios may not be acceptable. Obtain strata or body corporate reports: for apartments and townhouses, these reports reveal building defects, pending special levies and the financial health of the owners’ corporation. Significant defects or poor finances can affect loan approval. Order a building and pest inspection: independent inspections identify structural problems and unapproved work. Major defects can reduce the property’s value and cause the lender to require repairs. Check zoning and hazard overlays: local council zoning maps show whether a property sits in a flood, bushfire or landslip zone. High‑risk locations may need specialised insurance and can affect lender appetite. Research market comparables: look at recent sales of similar properties to understand the likely valuation. Unique homes or prestige properties often have more conservative valuations. Ask about the builder or developer: if you’re buying off the plan or a recently completed property, investigate the track record of the developer. Some lenders keep lists of builders they won’t work with due to past issues.

Why valuation surprises matter
Even with pre‑approval, the lender will commission a valuation of the specific property. If the valuer deems it worth less than what you’ve offered, the bank will base the loan on the lower figure. You will need to make up the difference in cash or renegotiate the price. Valuation shortfalls are more common with unusual properties, rapidly rising markets or dwellings with defects. Doing your own research or asking your broker to arrange a valuation early can help identify potential issues before you commit.
How early checking can save a deal from unravelling
Performing these checks before you fall in love with a property can save thousands of dollars in inspection fees and legal costs. If you discover early that a studio is too small for most lenders or that a rural property will require a much larger deposit, you can adjust your search or negotiate from a position of strength. A mortgage broker can help by accessing lender policy guides and advising which lenders accept particular property types. They can also suggest whether a larger deposit or a guarantor might overcome a property’s drawbacks.
When to get advice before you commit
If the property you’re considering is out of the ordinary such as a tiny studio, a rural block or a retirement village unit — talk to a broker or conveyancer before signing a contract. They can explain the implications of the title, the likely valuation range and any restrictions on finance. Even for conventional properties, it’s wise to involve your broker as soon as you have a shortlist. They can order preliminary valuations, review strata or building reports and flag any potential finance hurdles. Early engagement gives you time to solve problems rather than scrambling at the last minute.
Frequently Asked Questions
- Can a lender reject a property even if I am pre‑approved?
Yes. Pre‑approval assesses your financial position but not a specific property. If the property doesn’t meet the lender’s policies or the valuation is too low, the loan may be declined.
- Why are some apartments harder to finance?
High‑rise developments often have caps on the number of loans a bank will approve. Very small units may fall below minimum floor‑area requirements. Lenders also consider location and the building’s overall risk profile.
- What happens if the valuation comes in low?
The lender bases the loan amount on the lower of the purchase price or the valuation. If the valuation is lower, you may need to contribute a larger deposit or renegotiate the price.
- Should I check finance risks before making an offer?
Absolutely. Reviewing strata and building reports, zoning and comparable sales before committing can identify issues that might affect finance. A broker can also advise whether the property meets lender criteria.
- Can property condition affect approval?
Yes. Properties with major structural defects, unapproved alterations or poor maintenance can fail a valuation or be deemed ineligible. Addressing these problems or choosing a different property may be necessary.
