Keeping the Deal Alive: A Risk Plan for Private Property Transactions

An accepted offer is not a completion. In a private property sale, the absence of an estate agent can make the process quicker and cheaper, but it also removes a familiar chase mechanism. In 2026, deals still fall apart over mortgage delays, survey findings, title problems, slow conveyancing and simple cold feet. The seller who assumes that a good price means a completed sale, and the buyer who assumes that a handshake means certainty, are both exposed.

Why private deals come apart

The causes are rarely mysterious. A buyer’s mortgage application may be delayed by affordability checks, a down-valuation or missing documents. A survey may reveal damp, structural movement, an unusual lease or a defect that changes the buyer’s view of value. Searches may disclose a local authority issue, a flood risk or a planning problem. Leasehold sales can stall while management packs are requested and service charge accounts are queried. Conveyancing may simply move slowly, and in a private sale there is no agent pressing both sides for weekly updates.

Cold feet also matter. A buyer may see another property, lose a mortgage offer, or become nervous about a title defect that is actually minor. A seller may receive a higher offer and be tempted to reopen the deal. In England and Wales, until contracts are exchanged, neither side is usually legally bound to complete, subject to any separate agreement. Scotland has a different system, where missives can create binding obligations earlier. The practical lesson is the same: risk must be managed before exchange, not after.

A risk checklist for sellers

First, qualify the buyer before accepting. Ask for a mortgage decision in principle, evidence of deposit, confirmation that a solicitor or conveyancer has been instructed, and a realistic timetable. A buyer who cannot explain the source of funds or who has not spoken to a lender may still be genuine, but the seller should price in more uncertainty.

Second, prepare the pack early. Title documents, the Energy Performance Certificate, TA6 and TA10 forms, leasehold information, guarantees, planning permissions and building regulations certificates should be ready before the buyer’s conveyancer asks for them. Delay at this stage is often mistaken for reluctance.

Third, agree a written timetable with milestones: instruction of conveyancers, search orders, mortgage valuation, exchange and completion. A timetable is not a guarantee, but it exposes drift early.

Fourth, consider the deposit terms carefully. On exchange, a deposit is usually 10 per cent, although it can be negotiated. The deposit is not generally paid before exchange as a sign of good faith in a standard private sale. Any reservation fee or holding deposit should be documented and reviewed with legal advice, because the legal effect depends on the wording.

Fifth, think about exclusivity. A lock-out or exclusivity agreement can give a buyer a period of exclusive negotiation, but enforceability and practical value vary. A seller should take legal advice before signing one and should not grant exclusivity without a clear end date and exit terms. Continuing to market a property after exchange is not usually appropriate, but before exchange the seller must decide how much marketing risk to carry.

A risk checklist for buyers

Buyers should obtain a survey before exchange, confirm the mortgage offer and its conditions, review the search results and raise enquiries promptly. They should also verify that the seller’s title matches the property being sold, especially where land, parking, access rights or leasehold interests are involved.

A buyer should keep a reserve for unexpected legal or survey costs and should not pay a large sum to a seller before exchange without legal advice. Reservation fees and holding deposits are not standard in every private sale and may not be refundable. The buyer’s conveyancer should confirm the position in writing.

Insurance deserves early attention. Buildings insurance responsibility often passes on exchange, not completion, so the buyer should arrange cover from the correct date. Legal expenses insurance may assist with certain disputes, and title indemnity insurance may be available for some defects, but neither is a substitute for proper investigation.

Deposit terms and lock-out agreements

A deposit paid on exchange is part of the binding contract. If the buyer fails to complete, the seller may be entitled to retain it, subject to the contract terms. If the seller fails to complete, the buyer may have remedies under the contract. These are legal questions, not negotiating points to be left vague.

Lock-out agreements are sometimes presented as a way to stop gazumping or gazundering. They can be useful where both sides understand the terms, but they are not a standard feature of every residential sale. A poorly drafted agreement can create confusion about whether the seller may continue marketing or whether the buyer is obliged to proceed. The prudent course is to ask a solicitor or licensed conveyancer to review any such document before signature.

Communication habits that keep a deal moving

A private sale benefits from a single point of contact on each side and a written weekly update. Email is usually better than a stream of messages, because it creates a record of what was agreed. Key dates, changes to the timetable and requests for information should be confirmed in writing. If a mortgage offer is delayed, the buyer should say so early rather than allow silence to fill the gap.

Sellers should avoid treating every enquiry as a threat and buyers should avoid treating every delay as bad faith. A short, factual update is often enough to prevent a deal from becoming emotionally expensive. Where a chain is short or absent, the parties should still plan for contingency: a backup buyer, a later completion date or a fallback rental arrangement may be sensible.

When to reassess

A deal should be reassessed if the buyer cannot evidence funds, if searches reveal a problem that neither side will resolve, if the mortgage offer is withdrawn, or if the timetable has slipped repeatedly without explanation. Walking away is not failure; it is sometimes the rational response to unmanaged risk. In 2026, a private sale is most likely to succeed when both parties treat the period between offer and exchange as a structured process rather than a waiting game.
