iKey Facts
- •Amalgamation sales coordinate 2-5+ neighbouring landowners selling as a single site
- •Standard structure: each vendor signs separate contract, all cross-conditional on others completing
- •Pricing split usually by land area, sometimes by frontage or pre-agreed ratio
- •A single hold-out vendor can sink the entire deal — coordination is critical

Standard Amalgamation Structures
Model 1 — Cross-Conditional Separate Contracts Each vendor signs their own contract. All contracts conditional on all other vendors signing and completing. Most common.
Model 2 — Single Joint Contract All vendors are joint parties to one contract. Cleanest but requires alignment on every term.
Model 3 — Sequential Option Structure First vendor grants buyer an option. Buyer uses option as proof to secure remaining vendors. Riskier; rare.
Coordination Mechanics
For cross-conditional contracts:
- Common closing date — all vendors settle on same day
- Shared advisor — one specialist (ACRES) coordinates all vendors
- Documented pricing methodology — area-based, frontage-based, or pre-agreed split
- Tie-breaker mechanism — if one vendor disputes, defined resolution path
- Hold-out protections — buyer can't cherry-pick; all-or-nothing

- Hold-out neighbour kills the deal for everyone
- Disagreement on pricing split
- Different vendor circumstances (one needs fast settlement, another long)
- Trust between vendors — must align on shared advisor and decisions
Vendor Protections
Strong amalgamation contracts include:
- Cost-recovery clause if deal collapses due to one party
- Independent advisor (ACRES, not buyer's agent) acting for vendors
- Defined dispute resolution
- Equal information rights for all vendors
Pricing Premium
Amalgamated sites typically achieve 15-70% premium over sum of individual sales. The premium compensates for coordination complexity.

Frequently Asked Questions
What if one neighbour holds out for more money?
Hold-out leverage exists. ACRES negotiates "must-sign" thresholds (e.g., 90% participation triggers deal) to manage.
Can vendors have different settlement dates?
Usually no — buyer wants single settlement. Some structures allow staggered closing.
Who pays for the shared advisor?
Typically each vendor pays a pro-rata share of total commission.
