How Far in Advance Should You Start Selling Your House? (A Real Consultation)

If you're planning a move with a real date attached, selling your house becomes a timing puzzle. Maybe you're emigrating, starting a new job, or working around a school year. Start too late and you miss the date. Sell too quickly and you can end up completing months before you're ready to go.

I've now done around 800 free consultations with home sellers. This call was with Carla (not her real name), who's moving back to her home country after twenty years in the UK. We spoke in early September, about six months before she wants to be gone. Her four-bed house had been quietly sitting on the market for a couple of months with no offers, and the quick-sale leaflets were starting to look tempting. I've changed some details to protect her privacy.

It turned out her timing was close to perfect, and nothing about her sale was actually broken. By the end of the call she had dates on every step of the plan, and it's a plan almost anyone selling ahead of a move can copy.

So, how far ahead of a move should your house go on the market?

Sellers working towards a fixed moving date should allow around seven months from listing to completion. On average it takes 62 days to find a buyer, then another 154 days to complete. With six months or less to go, the answer is a well-planned launch or relaunch, never a panicked price cut or a quick-sale company.

But the reasoning matters more than the number, because the same maths that tells you when to start also tells you when not to panic...

If you'd rather cut straight to the chase, I've built a free quiz that works out which selling method fits your property and your priorities. It takes about 60 seconds, and you get your answer straight away.

Hit the button below to get started:

1. Carla's situation: a good house, a quiet market, a date

Here's where Carla was when she booked the call:

• A four-bed family home in a village-feel suburb of a commuter city.
  Well kept, with a garden, a garage and parking for two cars. A proper family house, in other words.
• On the market since midsummer at a little over £400,000.
  She's with a small two-person local agency on a twelve-week contract at 1% plus VAT, and she's about two months in.
• Around ten viewings, no offers.
  And no two viewers gave the same reason. That detail matters, and I'll come back to it.
• Moving abroad next spring, and in no hurry to leave.
  After twenty years in the UK she's heading home, but for personal reasons she was happy to have a few more months here first. Selling this autumn and being gone by Christmas was never the goal.
• Her priority was the price, not the speed.
  She'd worked hard for everything she has, and this sale funds the next chapter of her life. Giving a chunk of it away for a fast exit was never on the table.
• A mortgage with a sting in its dates.
  About £140,000 still outstanding, with an early repayment charge of 4% that drops to 1% on 1st March, around six months after our call.
• No panic, but no appetite to drift either.
  She didn't want to still be sitting there next summer.
• A letter through the door.
  A "we buy any house" company offering within a few thousand pounds of her asking price. More on that shortly.

Most sellers in her position start by asking how to sell faster. So the first genuinely useful thing we did was work out whether faster was even the right target...

2. Her real deadline wasn't "as soon as possible"

Carla's ideal completion date was early March, six months after we spoke. Partly that was personal: she was in no rush to leave and happy to see out the winter here. And partly it was financial: completing any earlier would have cost her roughly £4,000 in mortgage penalties, while completing much later would eat into the new life she's planned. A deadline like that is a window to hit, not a race to run.

Here's the mortgage maths:

• Paying off her mortgage before the end of February triggers a 4% early repayment charge, about £5,600 on her £140,000 balance.
• From 1st March the charge steps down to 1%, about £1,400.

So waiting a few extra weeks was worth roughly £4,000 to her, less a little extra interest along the way.

Carla had already decided she didn't need to sell fast and didn't want to rush. The mortgage simply put a number on the right month, and the pieces fell into place: March it is.

And there's a second, sneakier cost to selling too early. Say she'd found a buyer in September for a quick sale. Buyers usually don't like waiting five months to move in. (Imagine they had a baby on the way or some deadline of their own to meet.)

She'd have spent the winter warding off her own buyer, and a sale that sits in limbo like that has more time to fall apart.

So her brief wasn't speed at all. It was certainty: doing everything now to make sure the move actually happens in March, at a proper price.

Timing tip: Before you choose how to sell, ask your lender for your early repayment charge schedule in writing. Many charges step down on a fixed date. If yours does, the cheapest completion date may be later than you think, and if you're trying to avoid those types of charges then that can change which selling routes make sense for you.

Once you know the date you're aiming at, the next question is how much runway you actually need...

3. How long does selling a house actually take?

Rightmove's July 2026 analysis puts the average move at 216 days from listing to completion: 62 days to find a buyer, then another 154 days to complete the sale. That's around seven months. A seller who is six months from their moving date isn't ahead of schedule. They're merely on time.

That 216-day figure surprises almost everyone I share it with (you can see the trade coverage of it here). The completion half is quicker on houses than flats: around 149 days for terraced and semi-detached homes, against 169 for flats.

And those are averages of sales run on autopilot. In my experience, a freehold family home can complete in more like three to four months, if the seller gets their solicitor up and running early. I'll show you how in the plan.

For Carla, speaking in early September, the timetable worked backwards like this:

1. Completion in early March. The week her mortgage penalty drops, six months out.
2. A buyer by early December. Working back from a three-to-four-month completion on a freehold house.
3. Relaunched by mid-October. That gives six to eight weeks of fresh marketing to find that buyer. In a local market moving like hers (more on that below), that's realistic.
4. Notice to her agent now. Her twelve-week contract plus its notice period runs out around mid-October anyway, which makes the whole schedule click into place.

Sit that timetable next to her situation and something surprising drops out. Two quiet months in, Carla wasn't behind at all. She was exactly where the schedule says she should be, with nothing to spare.

That cuts both ways, of course. No reason to panic, but equally, no room to drift.

It's exactly at this point, a couple of months in with no offer, that the quick-sale routes start whispering. So we priced them properly...

4. Why the quick routes made no sense for her sale

The fast routes sell one thing: speed. Carla neither needed it nor wanted it. She was happy to stay a few months longer, her priority was getting a proper price for a house she'd worked hard for, and a sale completing before March would even have added roughly £4,000 in mortgage penalties. Paying £80,000 or more for speed she had no use for was the worst deal on the table.

Here's the route-by-route breakdown of why...

4.1. The "we buy any house" companies

Remember the letter through Carla's door, offering within a few thousand pounds of her asking price? She'd already clocked it as bait, and she was right.

Genuine, well-funded cash house-buying companies pay around 80% of a property's market value. On a house like Carla's, that's an offer of around £330,000. In other words, she'd be giving up roughly £80,000 in exchange for completing in a few weeks.

These companies suit people who value speed, certainty and convenience far more than price, and that is not most sellers. When someone books a call with me looking at house-buying companies, I end up suggesting a different route about 97% of the time.

For Carla it was even more clear-cut...

The whole point of this sale was to fund her next chapter at something like full value, and she had months to do it properly. A company completing in three weeks would trigger her 4% mortgage penalty too. She'd be paying roughly £80,000 for speed, and the speed itself would cost her another £4,000. I've broken down what these companies really pay, and why, in my guide to how much house-buying companies actually pay.

Fair warning: When a house-buying company claims it'll pay 90% or even 95% of market value, one of two things sits behind the claim:

1. A high offer that drops later, once you're committed and short of time.
2. No real purchase at all. They quietly go looking for a buyer for you, which leaves you no better off than with a decent local estate agent.

My guide to "we buy any house" scams covers the warning signs in full.

So the fastest route was out. The second-fastest didn't fare much better...

4.2. Selling at auction

Sellers typically give up 10 to 15% of a property's value at auction. On Carla's home, that's somewhere between £40,000 and £60,000, and you lose so much at auction for two reasons:

1. Fewer buyers. Most people either can't buy at auction or don't want to, so there's less competition to push the price up.
2. The wrong buyers. The people who do turn up are largely there hunting a bargain. That's the game.

And beyond the discount, hers is simply not an auction property. A well-kept four-bed family home in a commuter suburb sells to families, and families don't buy at auction.

For me, the deciding factor on auction is usually mortgageability. Auction comes into its own when a property can't get a mortgage, because investors are then the realistic buyers anyway. Carla's house is perfectly mortgageable, so auction would shrink her buyer pool for no good reason. I've set out the full trade-offs in my guide to the pros and cons of selling at auction.

Auction genuinely suits some sales though, especially properties that can't get a mortgage. If you're weighing it up for your own home, I've designed a free quiz that tells you in about 60 seconds whether auction fits your property and your priorities. If it does, I can introduce you to a leading auction house in your area. If it doesn't, I'll tell you what I'd suggest instead.

With the quick exits crossed off, one question remained. If the fast routes weren't the answer, why hadn't the normal route worked yet?

5. The last checks: was anything actually wrong?

Nothing about Carla's sale was broken. Sales were agreed on roughly a third of the competing homes nearby, the house matches its target buyer, the photos are good, and ten viewings without an offer is close to ordinary maths. The one weak link was reach: her agent could only access a fraction of the buyers.

Each of these checks is one you can run yourself, so here they are one at a time. Four came back fine, and one didn't...

5.1. The four things that were fine

• The market.
  Within half a mile of Carla's home, around 20 similar three-and-four-beds were for sale, and roughly a third of them had a sale agreed. We widened the search to the whole city as a sanity check, and got the same picture. We run this check all over the country and see anywhere from 10% to 50%, so a third is genuinely decent.
• The viewing numbers.
  A figure we've seen hold true for years is roughly one offer for every seven viewings. So ten viewings and no offers isn't far off the ordinary run of the odds, a bit like flipping a coin and getting heads twice.
• The feedback pattern.
  Sometimes the pattern matters more than the count. The thing I listen for is the same objection coming back again and again, because that points at something real. Carla's feedback was scattered: the cul-de-sac, the kitchen, personal taste. Six out of seven viewers never offer, and each has their own reason, so I've learned to read scattered feedback like this as "not for them" rather than as anything specifically wrong with the house.
• The photos.
  She'd paid for a professional package and it showed. Not the problem.

Market tip: The "bad time to sell" story is evergreen. I've been hearing it for years now. Seems to be because Estate agents love an excuse, and the media loves doom and gloom...

But the fact is, there's always something. Whether it's an upcoming budget, or the holidays, or interest rates, or the news.

I don't remember a single year in the past decade where sellers weren't told the market was against them, and pretty much the same number of homes kept selling anyway.

Run the two-minute check before you believe it: head to Rightmove and count the similar homes for sale within half a mile, then count how many have a sale agreed. It'll probably be more than you expect.

If your home is getting plenty of viewings and still no offers, I've walked through that exact diagnosis in another real consultation.

5.2. The one thing that wasn't fine: reach

Her agent was the problem. Not because they're bad people, or bad at their job, but because of what they don't have. Agents get viewings in three ways:

• Listings. Buyers spot the property on Rightmove or Zoopla and call in.
• The database. An agent selling lots of similar homes nearby is constantly fielding calls from buyers with the right budget for those homes, and those buyers go on a list the agent can ring for you.
• Cross-selling. When a buyer views a similar house and says no, that agent books them in to see yours instead.

We track our own numbers on this, and the portals generate only about 30% of our sales. The other 70% comes from those proactive routes. That goes completely against the grain of the common misconception that "Rightmove sells the house, so agents are all the same".

Carla's agency is a talented two-person firm, and over the years I've consistently seen the best individual agents leave the big companies to set up on their own. The catch is that they start off as a small business, and some never get past that.

In this situation, it meant they didn't have a single other listing in her area and price bracket. No similar stock means:

• No database to ring. Nobody with the right budget has been calling them about anything like her house.
• No viewings to cross-sell from. There's no similar home for a buyer to say no to first.

So every viewing she'd had almost certainly came from someone finding the listing themselves.

Tucked in a cul-de-sac with no passing traffic, that missing 70% was the whole story. (If your own sale has been stuck far longer, months or even years, the fuller version of this diagnosis is in my consultation on a house that hadn't sold in two years.)

So the fix wasn't a price cut, and it wasn't a fast exit. It was reach. And reach is fixable, especially if you have time to work with like Carla did.

6. The plan: a relaunch with a date on it

The plan is one big relaunch rather than a series of small changes: new agents, fresh photos and a re-evidenced price, all landing on the same day. One big splash, instead of three little ripples that each get ignored.

Here's the plan I gave Carla, step by step:

1. Read the contract and find your notice date.
   Almost every agency agreement adds a notice period on top of the fixed term, usually one or two weeks, sometimes four.
   
   Check two things: how long the notice period is, and whether you can serve it during the term or only at the end.
   
   That date is your relaunch date, and everything else works backwards from it. In Carla's case the contract simply runs out in October. If you feel genuinely trapped in yours, I've recorded a video on getting out of an estate agent contract early.
   
   Part of why changing agents works at all is human. Agents get tired of a property after a few weeks and drift towards their newest instructions, and that bites hardest with a small team like Carla's agent had. Move to new agents and you become the new property they're excited about.
2. Ask for the photos you paid for.
   Carla had paid £300 for professional photos, and they looked genuinely good. She paid for the package, so the files should be hers: ask for the originals in writing before you leave. Then plan two fresh shots anyway from the new agents:
   
   A new front photo, so the relaunch doesn't look like the same old listing to everyone who's been scrolling past it.
   
   And new garden photos. Right now that matters more than usual: gardens got particularly burnt out by the heatwaves during the summer just gone. Lawns are turning green again now, but if you're still showing those yellowy-brown garden photos into autumn and winter, you end up quietly telling buyers you've been waiting since July and no-one's wanted your home yet. A quick re-shoot removes that risk.
   
   Small changes, but each one gradually stacks the odds further in Carla's favour.
3. Get three agents out, and push the valuations for honesty.
   Agents overvalue to win instructions, and an overvaluation costs a deadline seller the one thing they can't buy back: time. Homes priced right at launch find a buyer in around 36 days on average, against 127 days when a cut is needed (Rightmove, July 2026).
   
   So say it to them plainly: "I need to complete in early March, which means I need a buyer by December. How do we price this so it sells and you earn your commission?" You're after a realistic price arrived at from evidence, rather than hope or pessimism.
4. Instruct two of them, not one.
   Using two agents at once is called dual agency, and most agents will agree to it. You get two listings on the portals (use different front shots so it genuinely earns a second look), two buyer databases being worked, and two teams cross-selling.
   
   It costs maybe an extra half a percent. You'll always see that fee on the bill, and you'll never see the money that the extra reach and competition made you. We still run sales this way, because it works.
5. Leave the fee structure alone.
   Carla had an idea on agent fees: offer the agent a bonus percentage for beating a target price. I talked her out of it.
   
   One thing I've learned over the years is that agents are effectively running a bulk business, and a quirky arrangement in one contract rarely gets remembered. We've tried things like it before, but I've never been convinced it's actually changed anyone's behaviour.
   
   Worse still, a bonus above a threshold gives the agent a reason to park your sale and wait for a lottery-ticket price while your date slides past.
   
   It misaligns your incentives with the agent's in another way too: the easiest way for them to hit the higher fee tier is to direct their negotiating efforts at you, to agree lower price thresholds. Agent fees are a necessary evil when it comes to selling, but I filmed a video a while ago sharing our process for negotiating £1,000s off estate agent fees.
6. Instruct your solicitor on relaunch day, not offer day.
   That 154-day completion average is mostly waiting: for paperwork, for searches, for forms nobody sent back. So get signed up the day the listing goes live, complete the ID checks, return every form, and ask your solicitor what a buyer's solicitor will want.
   
   A sale that starts at a sprint is how a freehold house completes in three to four months instead of five. And if your buyer turns up earlier than planned, being organised gives you a stronger hand to negotiate the completion date you actually want.
7. Then make it one big splash.
   On one day: the old board comes down, two new listings go live, new photos, and whatever price the fresh evidence points to.
   
   I prefer to make all the changes land at once. Make them one at a time and each one can pass unnoticed: a price nudge here, a new photo there, the same listing everyone has already scrolled past. Do the same work on one day and the property reads as a brand new listing to every buyer looking. I think about it like trying to make one big splash, instead of three little ripples.

7. Where Carla landed

Carla started the call thinking her market was the problem: the budget, the holidays, the time of year, and so on. She'd half-convinced herself the sale was going wrong, and the quick-sale letter on her doormat was starting to look like a lifeline.

But she finished the call with a timetable instead:

• This week: read the contract, find the notice date, request the photo files in writing.
• By mid-October: three valuations done, two new agents instructed, solicitor lined up for launch day.
• Early December: the window for finding her buyer, with six to eight weeks of fresh marketing behind it.
• Early March: completion, six months after our call and the same week her mortgage penalty drops from 4% to 1%.

Nothing about the house changed during our hour-long phone call. What changed is that the market went from a threat to a measured fact: a third of her competition selling, viewings arriving at a normal rate, and one fixable gap in the amount of exposure her home was actually getting.

Starting a sale six months before a fixed moving date, with a proactive plan, is definitely not too soon, and definitely not too late. It's pretty much right on schedule, and in my opinion that's the real lesson of this call: the sellers who hit their dates aren't the ones who panic in month two. They're the ones who put a date on every step, set the sale up correctly, stack the odds in their favour by getting some of the little details right, and basically spend the time on purpose, rather than letting months slip by.

If you've got your own moving date bearing down on a sale that's gone quiet, this is exactly what my free consultations are for. It's a proper one-to-one call with me, we work through your situation together, and you leave with a specific plan, the same way Carla did.

Thanks for reading, and good luck with your move.

Frequently asked questions

1

How long before moving should you put your house on the market?

For most homes, around seven months before a fixed moving date is the comfortable point to be on the market: Rightmove's July 2026 analysis shows 62 days to find a buyer plus another 154 days to complete. With less runway than that, a properly planned relaunch and an early-instructed solicitor can compress the completion part considerably.

2

How long does it take to sell a house in the UK in 2026?

The average seller takes 216 days from listing to moving: 62 days to find a buyer and 154 more to complete (Rightmove, July 2026). Completions run quicker on houses, around 149 days for freehold homes against 169 for leasehold flats. Either way, a well-prepared freehold sale can beat those averages.

3

Should I sell to a "we buy any house" company if I have a moving deadline?

A genuine house-buying company pays around 80% of market value in exchange for completing within weeks. On a £400,000 home, it means a loss of around £80,000. That trade only makes sense when you absolutely must sell quickly. With months of notice, a well-run estate agent sale can hit your dates, and you keep the money. I've covered the numbers in how much house-buying companies pay.

4

Can I speed up completion once I've found a buyer?

Completion averages 154 days in part because nobody starts the legal work until a buyer appears. Instructing your solicitor the day the listing goes live, completing ID checks and returning every form up front means the sale starts with some momentum, and a freehold house can then complete in more like three to four months.

5

Should I cut my asking price if my moving date is getting closer?

Rule out the other explanations first: an agent with no similar stock nearby, tired photos, a listing gone stale. If those checks are clear and the home has had real time on the market, then look at the price. Ask two or three agents what has actually sold nearby and what they would list at. If that evidence points lower, change the price once, decisively. I've shown that elimination running in full in a consultation on a house that hadn't sold in two years.
