Buyer and seller can’t agree on price: rescuing a stuck deal
Most stuck property deals die over a gap smaller than either side believes, because both are defending bluffed positions rather than real limits. An impartial AI mediator takes each side’s true bottom line in confidence, tests privately whether the positions overlap, and proposes a number and conditions both can accept — or tells you early, without revealing either number, that no deal exists.

Stuck property deals at a glance
A low appraisal or valuation, a building or pest report, a survey issue — the facts changed mid-deal, but both sides are still anchored to numbers set before the evidence arrived. Neither wants to be the one who moves first.
The buyer’s stated position and the seller’s stated position are negotiating stances, not real limits. Deals collapse over apparent gaps of tens of thousands when the true reserve and true ceiling overlap comfortably.
Each side tells the mediator its real limit in confidence. The numbers are never revealed — they’re only used privately to test whether the deal is still alive and to propose middle ground both sides can accept.
Finance conditions, appraisal contingencies, and settlement dates all expire. A mediated resolution in days beats weeks of email standoff — and both sides usually prefer a rescued deal to starting the market process again.
If the deal is under contract, any price change or extension is documented through your conveyancer, solicitor, or attorney. The Deal Memo records what was agreed so that amendment is fast and unambiguous.
How it works, step by step
- 1
Reset your real number from the new evidence
Whatever changed — a low appraisal, a building report, a market shift — set your new true limit from that evidence, not from the number you were defending last week. Sellers: what would a fresh sale realistically bring, minus the cost and delay of relisting? Buyers: what is the property worth with the defects priced in? That number goes to the mediator, not to the other side.

Start a mediation and invite the other side
Either party starts the mediation and sends the other a join link — a stalled deal usually just needs one side to propose a neutral process instead of another counter-offer. Each side gets a private channel to the mediator; neither can see the other’s.
- 3
Give the mediator your sealed bottom line
Tell the mediator your real limit and what you’d trade beyond price: settlement timing, repairs before settlement versus a price reduction, which conditions you’d waive. It is sealed — never disclosed, hinted at, or leaked to the other side in any form — so you can be honest without handing over leverage.

Let the mediator work the gap, bundling price and conditions
The mediator tests privately whether the two sealed positions overlap. Stuck deals often unlock on a bundle rather than a number: a smaller price cut plus an earlier settlement, or repairs completed instead of a discount. If the positions truly never overlap, it says so early — without revealing either number — before deadlines expire.

Close with a Deal Memo, then formalise
When both sides accept the same proposal, the mediator writes a Deal Memo: the revised price, conditions, timeline, and any commitments, in plain English. Both parties take the same document to their conveyancer, solicitor, or attorney to amend the contract or draft the new one — fast, because nothing is ambiguous.
The appraisal gap is a negotiation problem, not a valuation problem
When a lender’s appraisal or valuation comes in under the agreed price, three things can move: the price, the buyer’s cash contribution, or a mix of both. But by that point the negotiation has usually hardened — the seller feels the price was already agreed, the buyer feels the market just ruled in their favour, and every offer reads as an insult to someone. A neutral middle changes the dynamic: each side tells the mediator what it can genuinely do, and what crosses between the parties are the mediator’s proposals, not accusations. The same logic applies to building reports and surveys — the question is never whose fault the defect is, it’s whether a price exists that both sides still prefer to walking away.
Sealed by code, not by promise
The reason both sides can be honest with the mediator is that the confidentiality is enforced in code, not by a policy document. A settlement guard checks every proposal against both sealed limits before it is shared, so the mediator can never float a number that betrays where either side stands. A leakage guard screens every message to the shared channel so neither side’s numbers or private notes can leak in any form. What the other side sees are the mediator’s proposals and your accept/decline decisions — nothing else.
Know early whether to renegotiate or walk
Not every stuck deal deserves rescuing. If the seller’s true reserve sits above the buyer’s true ceiling, no amount of persuasion closes the gap — and the kindest thing a mediator can do is say so before another fortnight of deadline extensions burns goodwill and finance approvals. Because the mediator holds both sealed numbers, it can tell both sides early that no overlap exists, without revealing either figure. If you’re under contract, take that signal to your conveyancer or attorney promptly: your rights around conditions, deposits, and termination depend on the contract and your jurisdiction, and timing matters.
