Property auction and direct cash sale are the two fastest UK routes to a completed sale. They produce genuinely different outcomes — different timelines, different fee structures, different risks — and the right choice depends on the property and the seller’s priorities.
Quick comparison
| Traditional auction | Cash buyer | |
|---|---|---|
| Time to exchange | Auction day | 24 hours after acceptance |
| Time to completion | 28 days post-auction | 7–14 days from start |
| Deposit at exchange | 10% on day | 10% at exchange |
| Fees to seller | 2–3% commission, £300–£600 legal pack | £0 |
| Price certainty | Uncertain (reserve may not be met) | Certain (written offer) |
| Property exposure | 3–4 weeks marketing | None |
| Mortgaged buyers | Effectively excluded | N/A (we’re cash) |
How traditional auction works
- Instruct an auction house (regional or national). They value the property and agree a reserve price with you.
- Legal pack prepared — title, special conditions, searches — available to prospective buyers 2–3 weeks before auction.
- Marketing period — 3–4 weeks of listings in the auction catalogue, online portals, and (often) local signage.
- Auction day. Live or online. Bidders compete openly. If the reserve is met, the hammer falls and the property is sold.
- Exchange immediately after the hammer falls. Buyer pays 10% deposit on the day.
- Completion 28 days later. Buyer settles the balance; you move out.
If the reserve isn’t met, the property is withdrawn or sold privately post-auction at negotiated terms. You still pay the auctioneer’s fees.
How cash buyer works
- Enquiry — you share the property details.
- Written offer within 24 hours.
- Acceptance — solicitors instructed both sides.
- Legal work (day 2–7) — title, searches, enquiries, contract drafting. Most of this runs in parallel, so total elapsed time is 5–10 working days.
- Exchange — often same day as completion, or the day before.
- Completion — funds transferred, keys handed over, typically day 7–14 from first enquiry.
Price comparison
Auction price dynamics:
- Can exceed market value in hot demand (multiple bidders pushing the price).
- Often land 10–20% below market value — auction-experienced buyers factor the 28-day speed premium into their bidding.
- Specialist investment property, short-lease flats, and problem properties often do better at auction than on the open market.
- Typical actual hammer price: 75–90% of open-market value.
Cash buyer pricing:
- Firm written offer, not a range.
- Typically 80–92% of open-market value depending on condition and complications.
- Not affected by how many bidders exist on the day — the offer is the offer.
For a £320,000 property:
- Auction (typical): hammer at £280,000, less 2% commission (£5,600) and £400 legal pack, plus 3 months of carrying costs (£2,550) = £271,450 net.
- Cash buyer: offer at £281,600, no fees, no carrying costs = £281,600 net.
The cash buyer net return is often slightly higher despite the apparently lower headline price, because the fee structure and timeline compress costs. For investor-quality property in a hot auction market, auction can outperform — but it’s far less predictable.
When auction is the right choice
- Specialist investor property — short-lease flats, tenanted HMOs, development opportunities. Auction’s natural buyer is an investor.
- Unmortgageable property with strong underlying appeal to cash buyers (refurbishment opportunity, interesting character). Auction concentrates the buyer pool.
- Properties where bidding competition is plausible — unique features, rising market area, known under-supply of similar stock.
- You have 7–10 weeks and can tolerate the reserve-not-met risk.
When cash buyer is the right choice
- You need a certain completion date — a chain-break rescue, a specific onward purchase date, a repossession hearing.
- The property is unusual in ways that don’t suit auction — probate with executors who need to wait for grant, divorce sales where both parties need written-offer certainty.
- You want to avoid the withdrawn-at-auction risk. If your reserve isn’t met, you’ve paid fees and still don’t have a sale.
- You value privacy — no public listing, no catalogue, no competitive bidding visible to your neighbours.
- Speed matters more than absolute top price.
The honest caveats
- Reserve-setting at auction is a judgement call. Set the reserve too high, the property is withdrawn and you pay fees. Set it too low, you may sell significantly below market.
- Auction legal packs cost money — £300–£600 — and are paid whether the property sells or not.
- Post-auction sales (where the auctioneer negotiates with a bidder after the day) often settle below reserve, defeating the purpose.
- Not all cash buyers are principals. Verify the firm you’re dealing with. The quick house sale company glossary entry covers the sector distinctions.
