Modern Method of Auction Explained: The Fees Sellers Miss

The Modern Method of Auction (MMoA), also called conditional or online auction, is marketed heavily to sellers who want speed. It is a legitimate route — but the way it is paid for catches people out.

How it differs from a traditional auction

Traditional (unconditional) auction: the hammer falls, contracts are exchanged there and then, the buyer pays a deposit and completion is typically 20 to 28 days later. The buyer is legally committed immediately.

Modern Method (conditional): the winning bidder does not exchange at the end of the auction. They pay a non-refundable reservation fee and secure an exclusivity period — commonly 28 days to exchange and a further 28 days to complete, so around 56 days in total. The buyer is not contractually bound to buy until exchange.

Who pays, and how much

This is the crux. In MMoA the buyer usually pays the reservation fee, often quoted as a percentage of the purchase price subject to a minimum, and it is frequently non-refundable. Because buyers factor that fee into what they can afford, it typically depresses the bidding — so the seller pays for it indirectly even when the invoice has someone else''s name on it.

Always ask the auctioneer, in writing:

• Exactly what the buyer pays, and whether it counts toward the purchase price (often it does not)
• What the seller pays: entry fee, marketing, legal pack costs, and any commission on top
• Whether the reservation fee is refundable if the buyer withdraws
• What happens to the fee if the sale falls through because of something in the legal pack

The timetable risk

Because the buyer is not committed until exchange, the 56 days can end with nothing. A mortgage can be declined, a survey can come back badly, a buyer can simply walk and forfeit the fee. You have then lost two months of marketing time and the property carries the "previously sold" flag on the portals.

The counter-argument is real too: the non-refundable fee means MMoA buyers drop out far less often than ordinary private-treaty buyers.

When MMoA is a good fit

• Properties that are mortgageable and will attract competitive bidding
• Probate and repossession sales where transparency of process matters to the seller
• Sellers who want a defined timetable but a wider buyer pool than a traditional auction room

When it is not

• Unmortgageable property — short leases, structural movement, non-standard construction. MMoA buyers usually need finance, and finance is exactly what these properties cannot get. A traditional unconditional auction or a cash buyer suits far better.
• Sellers who need a guaranteed completion date. Conditional means conditional.
• Low-value properties where a percentage-based reservation fee is proportionally very large.

Comparing the three routes honestly

Estate agent — typically 4 to 6 months to completion, usually the highest price, lowest certainty, agent commission plus your own legal fees, and finance-related fall-throughs are common.

Modern auction — around 8 weeks if the buyer holds, variable price, medium certainty, entry and marketing costs to the seller, and the buyer can still withdraw before exchange.

Cash buyer — 7 to 28 days, discounted price, highest certainty, legal fees covered, and no mortgage to be declined.

Which is best depends entirely on whether your problem is price or certainty. If you have six months and a mortgageable house, use an agent. If your property cannot be mortgaged, or you need a date you can plan around, an unconditional auction or a direct cash sale will serve you better.
