The 28 Day Auction Clock: What Has To Happen in Week One

Everyone buying at auction stares at the same number. Twenty-eight days. It sits in the catalogue, it gets repeated by everyone in the room, and it becomes the thing people plan around.

It’s the wrong number to worry about. Twenty-eight days is plenty of time to complete a purchase. What kills these deals is week one, and almost nobody is thinking about week one when the hammer comes down.

Can you pull out after bidding at auction?

No. Not without losing money. At a traditional auction the hammer is the exchange of contracts, so once it falls you are committed, and if you walk away you lose your deposit and can be pursued for the seller’s losses on top.

This is the bit that catches first-time auction buyers, and it’s worth being blunt about it.

When you buy through an estate agent, you view the property, you put an offer in, the agent takes it to the seller, and the seller accepts. At that point nothing has happened legally. No contracts, no commitment, and you can walk away.

At a traditional auction, the fall of the hammer is the exchange of contracts. There’s no cooling off period. Nothing is subject to survey. You’ve bought it.

You pay ten per cent on the day, and the balance by the completion date. If you pull out, you lose that ten per cent, and the seller can come after you for their losses on top. If the lot goes back to auction and sells for less than you bid, you can be liable for the shortfall as well as losing your deposit.

That’s why the preparation matters more here than anywhere else in property.

How long do you have to complete on an auction property?

Usually twenty-eight days from the hammer, but it varies and you should never assume it. Twenty-eight days is the common period, not a rule. Some lots are fourteen. Some auction houses count twenty working days instead, which lands in roughly the same place, and a bank holiday in the middle buys you a day or two at most.

The only date that counts is the one in the special conditions of sale. Find it before you bid, not after.

While you’re in the catalogue, find the buyer’s administration fee too. It’s on top of your deposit and it’s cash you need on the day.

Week one, day by day

Here’s what the first seven days need to look like. If all of this has happened, you’ve got around three weeks of legal work left, and three weeks is enough.

One thing people don’t expect is that the terms themselves often carry an expiry, sometimes only a couple of weeks. The offer can run out before the purchase does.

Your real deadline is the valuation

If you take one thing from this, take this. Your deadline isn’t day twenty-eight. It’s the valuation, and it’s much earlier than you think.

A physical valuation takes a week or two to get booked, then around another week for the report to come back. Work that forward.

A week of drift at the front costs you a week at the back, and the week at the back is the one you can’t compress. That’s the whole argument for treating week one as the emergency.

Do you always need a valuation on an auction purchase?

No, and this is the single most useful question you can ask on day one: can this be done without a physical valuation?

Plenty of bridging lenders will work from a desktop valuation or an automated valuation instead, usually where the loan sits at a more conservative level against the property’s value. If that’s available on your deal, the timeline changes completely. The application goes in, the valuation is agreed, and the offer can follow within days.

The trade-off is real though. If you want to borrow the absolute maximum, you’ll almost certainly need a physical valuation. You can’t have both the highest borrowing and the fastest route, so decide which one the deal actually needs.

Buying under value is not a deposit

This one catches people who think they’ve bought well, so it’s worth saying plainly.

Lenders advance against the lower of the purchase price and the valuation. Every one of them works this way.

So say you buy a house worth two hundred thousand pounds for a hundred and fifty. You haven’t created fifty thousand pounds of equity you can borrow against. The lender works off the hundred and fifty. Seventy-five per cent of a hundred and fifty thousand is a hundred and twelve thousand five hundred, not seventy-five per cent of two hundred thousand.

Getting a lot under market value is a good deal. It isn’t a deposit, and it won’t reduce what you need to put in.

It’s also worth saying that a cheap lot at auction isn’t the same thing as a below market value transaction, which is a different structure altogether.

Is there a minimum bridging loan amount?

Yes, and it is the thing that catches people out on cheap lots. I get this call most months and it’s always the same conversation.

Bridging lenders have minimum loan sizes. The very floor of the market sits in the mid twenty thousands, but that’s a small handful of lenders. Most of the well known names won’t look at anything under a hundred thousand.

There’s a second test on top, and it’s the one that surprises people. Lenders also set a minimum property value, usually somewhere between a hundred and a hundred and fifty thousand pounds, regardless of how little you’re borrowing.

So a lot with a ten thousand pound guide price is a cash purchase. There’s no lender for it at any price. I had exactly this a few weeks ago on a terrace in Lancashire, and nobody tells you that before you register to bid.

Can you get a mortgage on an auction property?

Sometimes, but rarely inside the deadline, and that is the real problem.

There’s no rule against using a mortgage to buy at auction. Plenty of lots are perfectly ordinary houses and a mainstream lender would be happy with them in principle. The difficulty is the timetable. A residential or buy to let application typically runs to six to ten weeks, and you have four. If anything at all goes sideways, a query on the title, a document an underwriter wants, a valuer who asks for a structural report, you are past your completion date and your deposit is at risk.

And a good proportion of auction lots aren’t mortgageable as they stand. No working kitchen or bathroom, a short lease, non standard construction, or works needed before anyone would live in it. Those are often exactly why the lot is at auction in the first place.

That’s the gap auction finance fills. A bridging loan for an auction property is designed around the deadline rather than your income, it will lend on a property in poor condition, and the exit is a sale or a refinance once the works are done and the property is mortgageable again.

So the honest answer is that if your lot is conventional, your mortgage is already agreed and your lender knows the deadline, a mortgage can work. If any one of those three isn’t true, plan on bridging and refinance afterwards.

Six ways these deals die

Every failed auction purchase I’ve seen is one of these six, and not one of them is bad luck.

• The legal pack got read after the bid instead of before. A short lease, a missing title, a right of way through the garden, a tenant nobody mentioned. All of it was in the pack, free to download, before you raised your hand.
• A conveyancer who doesn’t do auction work. A normal residential conveyancer works to a six to ten week timetable. You’ve got four. Ask them one question before you instruct: how many auction completions did you do last year? If they pause, use somebody else.
• The valuation comes in under what you paid. Your loan drops, and you have to find the difference in cash, in days.
• The property simply isn’t lendable. No energy certificate or one below an E. Non standard construction, concrete, prefab, single skin brick. Cladding with no EWS1 certificate. A lease too short, and most lenders want sixty years or more still running when the loan is repaid. Any one of those and a lot of lenders say no however good the price was.
• You run out of cash before you run out of time. The deposit, the auction house fee, stamp duty with the surcharge on top if it’s an additional property, your solicitor, the lender’s solicitor, the valuation fee. People budget for the deposit and forget the rest.
• Adverse credit that surfaces in week three. A default, a satisfied county court judgment, an arrangement you’d forgotten about. There are lenders who are entirely relaxed about all of it, but they have to know on day one. Switching lender in week three isn’t a plan.

Four things to do before you bid

Do these four and week one is admin. Skip them and week one is a panic, and panics cost you your deposit.

1. Read the legal pack properly, and have your solicitor review it. If you want to use AI to help you get your head round a long document, fine, but it isn’t a substitute for someone qualified reading it.
2. Appoint a solicitor who does auction work, and give them the lot number and the auction date before the auction.
3. Get terms agreed in principle on the lot you’re actually going for, and ask whether it can be done without a physical valuation.
4. Add up every cost, not just the deposit.

And one more that isn’t about finance at all. Line up your trades before you complete, because you already know roughly when you’ll get the keys. I got quoted for some fencing in October and the chap couldn’t start until December. If your refurbishment plan assumes someone can start the week after completion, check that with them rather than hoping.

Go to an auction before you bid at one

The best advice I give clients costs nothing. Go to an auction when you’re not buying.

Sit in the room, watch what happens, talk to the auctioneers, see what lots actually go for against their guides. If a lot guided at two hundred and fifty thousand sells for three hundred, you’ve just learned what guide prices mean in that area, and you’ve learned it without any money on the table.

Then when you do go back to bid, you know the room, you know the process, and you can make a decision rather than a guess. It sounds soft. It isn’t. Comfortable people make better decisions under pressure, and an auction room is pressure.

And set your maximum before you walk in. If we’ve worked out terms based on two hundred and eighty-five thousand, that’s your ceiling. Don’t bid three hundred and ring me afterwards, because the deal we built doesn’t exist at three hundred.

Auction finance questions people ask

How long after an auction do you have to complete?

Commonly twenty-eight days, sometimes fourteen, and some houses count twenty working days. The binding date is in the special conditions of sale for your lot.

What happens if you pull out of an auction purchase?

You lose the ten per cent deposit you paid on the day. If the lot goes back to auction and sells for less than you bid, you can also be liable for the shortfall and the seller’s costs.

Do you need a survey to buy at auction?

No, and that is the risk. Nothing is subject to survey, so any survey you want has to be done before you bid, at your own cost, on a property you don’t yet own.

How fast can a bridging loan complete on an auction purchase?

Fast enough for a twenty-eight day deadline when the groundwork is done before the auction. What decides it is whether the application went in on day one and whether a physical valuation is needed.

Can you borrow against the value rather than the price you paid?

No. Lenders advance against the lower of the purchase price and the valuation, so buying under market value doesn’t increase what you can borrow.

Can you use bridging finance for the refurbishment as well as the purchase?

Yes. The works are usually funded as a drawdown facility released in stages as the work is done, rather than handed over at completion. There’s more on that on our refurbishment bridging page.

Twenty-eight days is enough. Starting on day four isn’t.

That’s really the whole thing. The timescale at auction isn’t the problem, and bridging finance exists precisely because mainstream lending can’t move at this speed.

What goes wrong is the first week. Documents that arrive slowly, a solicitor instructed late, a valuation booked on day nine instead of day two. None of it feels urgent at the time, and all of it lands on the completion date.

If you’ve got a lot you’re thinking about, the useful conversation happens before the auction, not after. Send me the lot and the legal pack and I’ll tell you what’s possible, what it’ll cost and how fast it can move. If the answer is that it won’t work, you’ll hear that too, and you’ll have heard it before you’d committed anything.

Your property may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

This is general information, not a quotation, an offer of finance or personalised advice. No lender is named. Rates, fees, timescales and lender criteria vary by lender and by deal, and the terms available to you may be different. Bridging finance is short-term secured borrowing and it can be expensive. If a secured loan is not repaid in line with its terms, the lender may take enforcement action against the property or any other security provided.
