Auction vs Cash Buyer: Which Actually Sells Faster?
Fees, timescales, reserve risk and price outcomes compared honestly for both routes.
The 60-second answer
- Auction typically achieves a higher price, in 6–10 weeks, with 2–3% + VAT fees and no guarantee the reserve is met.
- Cash buyer typically pays 75–85% of market value, in 7–21 days, with no fees and full certainty on completion.
If you need to complete on a specific date, cash wins. If you have 8+ weeks and the property is priced well, auction can beat cash by 5–10%.
Auction basics
Traditional (unconditional) auction
- Contracts exchange on the fall of the hammer
- 10% deposit paid on the day
- Completion 28 days later
- Buyer forfeits deposit if they pull out
Modern (conditional) auction
- Buyer pays a non-refundable reservation fee (typically 3–4.5% + VAT, sometimes 5%)
- 28 days to exchange, 28 days to complete (56 days total)
- Opens the buyer pool to mortgage-backed buyers
- Seller often receives 90%+ of market value
Fee comparison
| Item | Auction | Cash buyer | | --- | --- | --- | | Sale-side fee | 2–3% + VAT | £0 | | Reserve marketing fee | £500–£1,500 | £0 | | Legal pack fee | £250–£500 | Usually paid by buyer | | Withdrawal fee if reserve not met | £1,000–£2,500 | N/A |
Certainty comparison
- Auction reserve missed: ~15–25% of lots don't sell on the day.
- Cash buyer withdrawal: rare with a regulated buyer once written offer is agreed and survey completed.
Net outcome worked example
£220,000 property, empty probate, no chain:
Auction (modern, reserve £200k): hammer £215,000 − fees ~£7,600 = net £207,400 over 8 weeks. Cash buyer: offer £178,000, £0 fees, complete in 2 weeks.
The cash route is £29,400 lighter — but it's also 6 weeks faster with no reserve risk.
Frequently asked questions
Is auction always cheaper than an estate agent?
No. Auction fees are usually higher than a good online agent, but they buy speed and certainty.
Can I set a hidden reserve?
Yes. Auctioneers set a guide price (marketing figure) and a reserve (minimum acceptable) — the reserve is confidential.
What if my property doesn't sell at auction?
You can re-enter the next auction, accept a post-auction offer, or switch to a cash sale.
