Mistake 1: No written agreement — why a verbal sale is void
The most fundamental mistake in any private property sale is failing to record the agreement in writing before either party starts relying on it. Buyers begin making renovation plans, sellers start looking for a new home — and then one party changes their mind, only to discover that without a written agreement there is no legal recourse at all.
Under section 2(1) of the Alienation of Land Act 68 of 1981, an agreement for the sale of immovable property must be in writing and signed by both parties to be valid. A series of WhatsApp messages, a handshake, or a verbal price agreement is worthless in court — the law treats it as no sale at all. Even a partial written agreement that is missing key terms may be unenforceable.
How to avoid it: do not proceed with any aspect of the transaction — paying a deposit, moving out, giving notice on your bond — until a properly signed offer to purchase is in hand. A few hours spent getting the paperwork right before signing protects both parties from expensive disputes after the fact.
Mistake 2: Using a generic OTP template
Downloading a free OTP template from the internet and filling in the blanks is one of the most common — and potentially costly — private sale mistakes. Generic templates are drafted for the average transaction, which means they routinely omit clauses critical to your specific situation. A template written for a Cape Town freehold property may miss Tshwane-specific municipal practicalities, estate levy clearances, or sectional-title provisions.
Poorly drafted templates frequently leave out the suspensive condition for bond approval (a critical buyer protection), fail to specify which fixtures are included, use outdated terminology, or contain conflicting clauses that create ambiguity. When a dispute arises, an ambiguous or incomplete OTP is a gift to the party who wants to wriggle out of their obligations. Our guide to the offer to purchase sets out what a complete OTP must contain.
The voetstoots clause is the classic example of template trouble. Voetstoots never protects a seller who deliberately conceals a known defect; in sales by developers or anyone selling in the ordinary course of business, the Consumer Protection Act 68 of 2008 overrides voetstoots entirely; and in estate-agent-mediated sales the Property Practitioners Act 22 of 2019 makes a signed seller disclosure form mandatory. Even in a pure private sale, completing the property disclosure form is best practice — our voetstoots and defect disclosure guide covers the law in full. A generic template handles none of this nuance.
How to avoid it: if you must use a template, have it reviewed by a conveyancer before either party signs. Alternatively, use our OTP creator, which generates a complete, legally sound offer to purchase tailored to the South African legal framework, with all the essential clauses included.
Mistake 3: Leaving out suspensive conditions
A suspensive condition is a clause that makes the sale conditional on a future event. The most important is the bond condition: the sale is subject to the buyer obtaining a home loan of a specified amount within a specified period. Without this clause, a buyer who needs finance is contractually obligated to pay the full purchase price — even if the bank declines the bond application.
This mistake is surprisingly common, especially when buyers and sellers are eager to close the deal and do not want to introduce “doubt” into the agreement. But the doubt is already there — the bond may or may not be approved. The suspensive condition simply ensures the contract fairly reflects reality: if there is no finance, there is no sale.
How to avoid it: every suspensive condition must specify a deadline and the consequence if it is not met. Common conditions to consider: bond approval, the sale of the buyer’s existing property, approval from a homeowners’ association, and a satisfactory building inspection. Our suspensive conditions guide covers the standard wording and timing of each.
Mistake 4: Underestimating transfer costs
Buyers frequently underestimate the total cost of acquiring a property because they forget to budget for transfer costs — the costs payable over and above the purchase price. Transfer duty (payable to SARS), transfer attorney fees, Deeds Office levies, and bond registration costs (if taking a home loan) can add R80,000–R150,000 to the total cost of a R2 million property. Our transfer costs guide breaks down every line item.
Sellers are not immune to this mistake either. The costs of selling include the cancellation attorney’s fees (to cancel your existing bond), any shortfall between the sale price and your outstanding bond balance, rates and levy clearance figures, compliance certificates, and — if an agent is involved — the estate agent’s commission. Sellers sometimes discover too late that the net proceeds from the sale are significantly less than they expected.
How to avoid it: use the transfer cost calculator and the bond cost calculator to get accurate estimates before you commit to any sale, and ask the transfer attorney for a written, itemised cost estimate at the start of the instruction.
Mistake 5: Skipping the compliance certificates
In South Africa, the seller must provide an electrical compliance certificate (CoC) before transfer — it is mandatory on every sale, typically costs R850–R1,500 for the inspection and certificate if the installation passes, and is valid for two years. Depending on what the property has, other certificates may also be required: a gas compliance certificate where there is a fixed LPG installation, and an electric fence system certificate (SANS 10222-3) where there is an electric fence. A beetle certificate is a coastal convention — in Gauteng it is usually required only where a bank or the OTP insists on it. A separate plumbing certificate is required by the City of Cape Town only; sellers elsewhere often arrange one under the mistaken belief that it is compulsory nationwide. Our seller’s guide sets out the full certificate matrix.
Private sellers often forget to arrange these certificates early in the process, only to discover defects when the inspector attends the property. Rectifying non-compliant electrical installations or gas fittings can take weeks and cost thousands of rands. These delays push back the transfer date, frustrate the buyer, and can even result in the buyer exercising cancellation rights if the transfer is not registered within the time frame specified in the OTP.
How to avoid it: arrange all required compliance inspections as soon as the OTP is signed — or even before listing. If defects are found, address them immediately. Your transfer attorney will confirm exactly which certificates apply to your property.
Mistake 6: Appointing the conveyancer too late
Many private sellers appoint a conveyancer only after the OTP is signed. By that point, any errors or missing clauses in the contract are already binding, and correcting them requires the buyer’s cooperation — which is not always forthcoming, particularly if the buyer perceives the change as disadvantageous.
Appointing a conveyancer before signing allows the attorney to review the OTP (or draft it from scratch), identify risk areas, and ensure the agreement properly protects your interests. In a private sale there is no estate agent in the transaction, so the conveyancer is the only professional checking the deal — see our guide to selling your house privately. A short consultation before signing costs a fraction of what it costs to resolve a dispute after the fact.
How to avoid it: contact a conveyancer at the same time as you begin negotiating with the other party — not after the deal is done. Early involvement means fewer surprises and a smoother transaction for everyone.
Frequently asked questions
A verbal agreement for the sale of immovable property is void in South Africa — not merely difficult to prove, but legally non-existent. Section 2(1) of the Alienation of Land Act 68 of 1981 requires every sale of land to be contained in a written deed of alienation signed by both parties or their authorised agents. A series of WhatsApp messages, a handshake, or a verbal price agreement creates no contract at all. If the other party withdraws, you have no legal recourse — regardless of any deposit paid or plans already made. Always get a properly signed offer to purchase before anyone relies on the deal.
Once both parties sign the OTP, it is a binding contract. Cancellation is only possible if: (a) a suspensive condition fails — for example, the buyer’s bond is declined within the stated period, in which case the agreement lapses automatically; (b) both parties agree in writing to cancel; or (c) the other party breaches the contract, entitling you to cancel after following the breach procedure in the agreement. Unilateral cancellation without one of these grounds exposes you to a claim for damages or for specific performance — a court order compelling you to go through with the sale.
A compliance certificate (CoC) is issued by an accredited inspector and confirms that a system — electrical, gas, or electric fence — complies with the relevant safety regulations. The seller is responsible for providing a valid electrical CoC on every sale; the other certificates apply only where the property has that installation. Without the required certificates, the transfer cannot proceed to lodgement, and registration is delayed while inspections are arranged and any defects repaired. Bond-granting banks also insist on the certificates before registration.
Yes — but you must disclose it to the buyer. Knowingly concealing a defect is fraudulent and can expose you to a damages claim even if the OTP contains a voetstoots clause. Voetstoots protects you from claims about latent defects you did not know about; it never protects deliberate concealment.
The safest course is to record every known defect in a written disclosure form attached to the OTP — mandatory in estate-agent-mediated sales under the Property Practitioners Act 22 of 2019, and best practice in a private sale. A defect disclosed in writing is a defect the buyer accepted.
Ideally before the OTP is signed. A conveyancer can review or draft the OTP, identify potential issues before they become problems, and make sure the agreement accurately reflects what both parties intend. Appointing the conveyancer only after signature means any errors in the document are already binding, and correcting them requires the agreement of both parties — which is not always forthcoming once interests have diverged.
