If you’re looking to buy a home but can’t get a standard bank loan, seller financing might seem like a perfect workaround. In a typical property sale, the buyer pays the full price upfront using a mortgage from a bank. With seller financing, the seller acts as the lender — you pay them in instalments instead. It’s a less common path, but one that can open doors for buyers who are self-employed, have irregular income, or a less-than-perfect credit history. However, it’s not a simple handshake deal. The arrangement comes with its own costs, legal hurdles, and even outright bans in some Australian states.

Seller financing isn’t a single product — it comes in several forms, each with different rules and risks. The three most common types are a terms finance (or wrap-around loan), a vendor-financed deposit, and a lease option or rent-to-buy agreement. Understanding which one you’re entering into is the first step. Here’s what you actually need to know.
The central concept here is the balloon payment.
What I tend to notice is that many buyers focus on the low monthly payments and forget about the balloon date entirely. That single deadline is where most deals fall apart.
Total costs of a seller-financed deal
The purchase price is only the starting point. In a seller-financed arrangement, you’re also paying a higher interest rate, legal fees for drafting the contract, and potentially stamp duty depending on your state. The seller isn’t a bank — they don’t have a compliance department checking every detail, which means the contract needs to be watertight. That costs money.
Here’s a breakdown of the typical fees and costs you’ll encounter:

| Cost item | Typical amount | Who pays |
|---|---|---|
| Down payment | 10–20% of purchase price | Buyer |
| Interest rate premium | 1–2% above bank rate | Buyer |
| Legal / conveyancing fees | $1,000–$2,000 | Buyer (usually) |
| Building inspection | $400–$700 | Buyer |
| Stamp duty | 3–5% of purchase price | Buyer |
| Balloon payment | Remaining balance after term | Buyer |
One scenario that catches buyers out: you agree to a $500,000 property with a 10% down payment and a 30-year amortisation schedule, but the balloon is due in 5 years. Your monthly payments are low — maybe $2,000 — but after 60 months you still owe roughly $450,000. If you can’t refinance or sell, you’re in trouble. That single balloon date is the most consequential trigger in the entire deal.
If you’re unsure about the legal side of drafting or reviewing a seller-finance contract, a service like JustAnswer Real Estate Law can connect you with a property lawyer who can review the terms before you sign.
Common mistakes buyers and sellers make
Treating the balloon date as a formality
The most financially damaging mistake is assuming you’ll easily refinance when the balloon comes due. If your credit hasn’t improved, or if property values have dropped, a bank won’t lend you the full amount. You then face default. The seller gets the property back, and you lose everything you’ve paid. A realistic refinancing plan — not a hopeful one — is essential from day one.
Skipping independent legal advice
Both parties should get their own lawyer. A seller might draft a contract that heavily favours them — for example, a clause that allows repossession after a single missed payment. A buyer might sign without realising the interest rate can be adjusted mid-term. Independent legal review costs a few hundred dollars but can prevent a total loss. In Victoria and South Australia, where vendor finance is banned, any attempt to use it can void the contract entirely.
Ignoring the full cost picture
Buyers often compare only the monthly payment to a bank mortgage. But seller financing typically carries a 1–2% interest rate premium, plus legal fees, stamp duty, and inspection costs. Over a 5-year term on a $500,000 loan, that extra 2% adds roughly $50,000 in interest alone. The total cost can easily exceed what a bank loan would have cost — even if you couldn’t qualify for one initially.
Not having a backup plan
What happens if you lose your job, or interest rates rise sharply before the balloon date? Most seller-financed contracts don’t include hardship provisions. If you can’t pay, the seller has the right to repossess. A practical step is to build a cash reserve equal to at least 6 months of payments, and have a clear exit strategy — either refinancing or selling before the balloon date.
How seller financing actually works — step by step
Finding a willing seller
Seller financing isn’t advertised like a bank loan. You typically find it through private listings, real estate agents who specialise in creative finance, or directly approaching sellers of properties that have been on the market for a long time. Sellers who are motivated — perhaps they need to sell quickly or have had trouble finding a buyer — are more likely to consider it. You’ll need to explain your situation clearly and demonstrate that you’re a reliable payer, even if you can’t get a bank loan.
Negotiating the terms
Once a seller agrees in principle, you negotiate the key terms: purchase price, down payment (typically 10–20%), interest rate (usually 1–2% above bank rates), loan term (commonly 5–7 years), amortisation schedule (often 30 years), and the balloon payment structure. Both parties should put everything in writing. A promissory note outlines the repayment terms, and a mortgage or deed of trust secures the loan against the property. This is where a lawyer is essential — a poorly worded agreement can lead to disputes later.
Legal checks and inspections
Before signing, you need the same checks as any property purchase: a building and pest inspection ($400–$700), a title search to confirm ownership, and a strata report if you’re buying a flat. The seller should also provide a current certificate of title. If the property has any encumbrances — like an existing mortgage — the seller must disclose this. Some seller-financed deals require the seller to pay off their existing mortgage first, which adds complexity.
Exchange and settlement
Once the contract is signed, you’ll pay the deposit (usually 10%) into a trust account. Settlement typically occurs around 42 days after exchange, though this can be negotiated. At settlement, the seller transfers the title to you, and you begin making monthly payments according to the promissory note. The seller holds a lien on the property until the loan is fully paid off — including the balloon payment.
Planning for the balloon date
This is the most critical phase. From the day you sign, you should be working toward refinancing with a bank before the balloon date. That means improving your credit score, building a stable income history, and saving for a larger down payment. If refinancing isn’t possible, you may need to sell the property before the balloon date. Some buyers use the seller-financed period to renovate and increase the property’s value, then sell at a profit to cover the balloon. Whatever your plan, treat the balloon date as a hard deadline — not a suggestion.

Is seller financing right for your situation?
Seller financing can be a genuine path to home ownership for buyers who can’t get a traditional mortgage. But it’s not a shortcut — it comes with higher costs, a hard balloon deadline, and legal complexity that can trip up both parties. The buyers who succeed are the ones who treat the balloon date as a non-negotiable target, get independent legal advice, and have a realistic refinancing or exit plan from day one. If you’re considering this route, start by speaking to a property lawyer who understands your state’s regulations.
