Chain
In plain English: A line of dependent property transactions — each buyer is also a seller, all moving on the same day.
How chains work in practice
Imagine a first-time buyer at the bottom. They buy from someone moving to a bigger house. That person is buying from a family moving to the countryside. Each transaction depends on the one below it funding it. All links exchange and complete on the same day — usually a Friday.
Why chains break
- Mortgage delay at one link
- Survey issue on one property
- A buyer gazumping or gazundering
- Solicitor capacity or holiday gaps
- Divorce, redundancy or bereavement at any link
How to survive a chain
- Lock in your finance early — an agreement in principle on day one.
- Instruct a solicitor who handles chains routinely.
- Keep communication open — estate agents often drive chain coordination.
- Be ready for completion dates to slip; do not book removals firm until exchange.
Where Offrly fits
A realistic upfront Offrly valuation makes chain coordination smoother: you price correctly at the start, so the sale doesn't drag mid-chain while you reduce and re-list.
Why Offrly? It's the free photo-aware AI valuation — the AI reads each comparable's photos the way a seasoned property analyst would, and a hyperlocal regression resolves prices down to the street rather than the postcode. Live comparables on every query. About 30 seconds, no signup, no email.

How long is a typical UK chain?
Three to five links is common. Longer chains exist but become progressively more likely to collapse.
Can I avoid being in a chain?
Yes: buy from a first-time buyer, investor or developer (no onward sale), or buy chain-free (your seller has already moved). First-time buyers who are renting are themselves chain-free on the buy side.
What happens if one link collapses?
Everything stops. The break point has to find a new buyer or seller, which can take months. Chain-free properties trade at a small premium because of this risk.
