Off the Plan Potential Problem #41: Rental Market Changes
Explore CM Lawyers’ off-the-plan purchase services.
The rent quoted when you reserve an apartment may differ from what tenants will pay when it is ready. New supply, local demand and the property’s actual features can change the result. A workable investment plan should separate a rental estimate from a contractual guarantee and allow for periods when income does not meet expenses.
Why can the rental outlook change before an off-the-plan purchase settles?
The interval between exchange and completion exposes you to changes in demand, competing supply and household budgets. The finished apartment may also differ from the assumptions used in an early appraisal. Neither a rising market nor a weak market affects every suburb, building or apartment in the same way.
Check conditions again as completion approaches. Avoid treating a market description from the sales campaign as a current assessment. Nearby developments completing together may increase competition, but whether that affects your apartment requires local evidence rather than a general prediction.
Is a rental estimate the same as a rental guarantee?
No. An estimate expresses an opinion about likely rent; a guarantee is an obligation whose enforceability depends on its wording and the party giving it. Neither label removes the need for scrutiny. Ask who prepared the estimate, when it was prepared and what evidence and assumptions support it.
Keep the written appraisal and any qualification about furnishing, vacancy, incentives or completion. If someone calls an amount guaranteed, ask for the actual agreement. A verbal sales assurance should not be treated as equivalent to an independently checked contractual commitment.
Where can I find useful rental evidence?
Use recent evidence for comparable properties, supported by independent local property managers and official rental data. Compare achieved rents where available, rather than relying only on advertised asking rents. Record the date, dwelling type and area covered, because a broad median may not describe the apartment you intend to buy.
The NSW Rent and Sales dashboard and rental bond data provide useful context. New bond records concern new tenancies, not every existing lease. Check the dataset’s definitions and sample size before applying a headline figure to your property.
What makes another apartment a useful comparison?
Compare bedroom count, usable layout, parking, outdoor space, condition, furnishing, access and location. Also consider the likely tenant group and any competing apartments in the same building. A similar asking price or postcode is not enough to establish that two properties will achieve the same rent or attract tenants equally.
Ask an independent manager to explain why each comparison is relevant and whether incentives affected the reported result. My practical advice is to retain the reasoning behind an estimate, not just the weekly dollar figure at the bottom of the appraisal.
How do I work out the income actually available to meet expenses?
Start with realistic rent received, then account for vacancy, management fees, letting costs, strata levies, rates, insurance, maintenance and borrowing costs. Gross rental yield is not cash left in your bank account. Your budget should also allow for irregular expenses and the timing of payments, rather than annual totals alone.
Moneysmart explains investment property costs. Separate principal repayments from deductible expenses and obtain tax advice about the applicable rules. A possible deduction does not pay an invoice when it falls due or guarantee the investment will make a profit.
How should I allow for vacancy and lower rent?
Test whether you could meet the property’s expenses if finding a tenant takes longer or the achievable rent is lower than expected. Include your other commitments and accessible reserves. A plan that works only with immediate occupancy and the highest suggested rent deserves further assessment before you sign.
Use several plausible scenarios instead of a single forecast, and review them with your financial adviser or lender. If you own several similar properties, consider whether they could experience weaker demand together. A future resale should not be your only contingency.
What should I check in a rental guarantee agreement?
Identify the guarantor, term, payment calculation, exclusions, claim procedure and termination rights. Check whether the promised figure is gross or net and whether particular management, furnishing or letting arrangements are compulsory. Assess the guarantor’s ability to pay: a contractual right may have little practical value if the company becomes insolvent.
Ask what happens when the guarantee expires, the property is vacant, management changes or settlement is delayed. Have the guarantee and purchase contract reviewed together. A guarantee should not replace an independent assessment of the property’s ordinary rental prospects.
Can I increase the rent whenever my costs rise?
No. An increase in your mortgage repayments or other expenses does not itself allow an immediate rent increase. NSW generally limits increases to once in twelve months and requires at least sixty days’ written notice, with limited exceptions for certain older agreements. The tenancy’s terms and applicable rules must be checked.
Official rent increase guidance explains timing and notice requirements. Renewing a lease with a continuing tenant does not necessarily restart the clock. Budget for costs you may have to absorb rather than assuming you can pass every increase to the tenant immediately.
Can I invite applicants to bid more than the advertised rent?
No. NSW landlords and agents must advertise residential rental properties at a fixed price and cannot solicit or invite offers above that price. Applicants may make a higher offer freely and voluntarily, but financial pressure on the owner does not justify encouraging a bidding process or using misleading advertising.
NSW’s advertising rules explain the distinction. Keep descriptions accurate and respond to enquiries consistently. Review the asking rent against evidence if interest is weak, rather than assuming repeated relisting or competitive pressure will produce the original forecast.
Can I postpone repairs if the investment is losing money?
Financial pressure does not remove your obligations to provide premises fit to live in and maintain them in a reasonable state of repair. Urgent repairs require prompt attention. Poor maintenance can also affect tenant retention and future letting, so repairs should remain part of your operating budget during weaker rental conditions.
Landlord repair obligations and minimum housing standards continue throughout the tenancy. In strata, coordinate common property issues with the owners corporation, while meeting your own obligations to the tenant. Keep records of requests, responses and completed work.
Can I change property managers if the rent disappoints?
You can consider changing managers, but first distinguish market conditions from a failure to perform the management agreement. Check the agreed services, fees, notice period and termination process. Replacing the agent does not itself end the tenant’s lease or entitle you to alter the tenant’s existing rights.
NSW management guidance explains agreements and record transfers. Review inspections, enquiries, recommendations and authorised expenses before deciding. If you wish to end a tenancy, separate lawful grounds and notice requirements apply; wanting a better return is not a general cancellation power.
Can falling rental expectations let me cancel the purchase?
Usually, disappointing rental prospects do not themselves create a right to cancel a binding off-the-plan purchase. Review any express conditions, guarantees, disclosure issue or actionable representation with your solicitor. Do not assume you can withdraw, recover the deposit or cap your exposure at the deposit simply because the investment looks less attractive.
NSW off-the-plan guidance explains specific protections. The legal question is whether a particular contractual or statutory right arises on the facts. Preserve evidence and seek advice promptly before missing a settlement obligation or sending a termination notice.
When might a rental forecast be misleading?
A business making a prediction about future rent must have reasonable grounds for it when made. A claim may be misleading without deliberate dishonesty. Conversely, a disappointing result alone does not establish liability. The wording, surrounding circumstances, evidence, reliance and loss all need assessment under the relevant legal rules.
ACCC guidance covers future claims, while NSW guidance addresses property agents. Save appraisals, advertisements and messages, including qualifications. Identify who made or adopted the statement. A complaint or legal claim should address the evidence rather than treat every market movement as wrongdoing.
What does a real rental guarantee dispute show?
Chen v Feng [2020] NSWCATCD 8 shows that a rental guarantee and a claim against individuals behind an agency are different things. The dispute concerned a Brisbane apartment managed through an agency connected with NSW. The agency’s financial collapse left the investor seeking compensation from its licensee and another individual.
NCAT rejected the rental guarantee claims against those individuals on the evidence. The guarantee was a contractual obligation of the agency, but failure to pay did not itself establish the alleged misleading or unconscionable conduct. The Tribunal separately ordered the licensee to pay limited compensation for mishandling client funds; the application was otherwise dismissed. The case concerned a short-term letting arrangement and its particular evidence, not a general rule about ordinary NSW residential leases. The practical lesson is to examine the guarantee’s terms, the obligor’s financial capacity and the evidence supporting any separate claim.
