We’ve all heard the horror stories. A friend’s house that sat on the market for eight months. A colleague who had to drop their asking price three times. The neighbour who’s still showing viewers around after six months with no serious offers.
Selling your home doesn’t always have to be so stressful. The biggest mistakes that often prevent quick sales tend to be surprisingly easy to fix once you know what you are doing wrong.
After helping thousands of families move across Buckinghamshire, Bedfordshire, and Hertfordshire over the past 30 years, we’ve seen the same costly errors repeated time and again. The good news? They’re all avoidable.
1. Falling in Love with an Unrealistic Price
It’s completely natural to have an emotional attachment to your home’s value. You remember what you paid, you’ve invested in improvements, and you know it’s worth every penny to you. But here’s the thing – the market doesn’t share your emotional connection.
We’ve seen sellers add £20,000 to their asking price because “someone might pay it” or because they need the extra money for their next purchase. Unfortunately, buyers aren’t charitable. They compare properties, and if yours is overpriced by even 5%, they’ll simply move on.
The warning signs you've overpriced:
- Silence. No viewing requests in the first two weeks
- Viewers who seem unimpressed despite your home being in great condition
- Comments like "it needs a lot of work" when it clearly doesn't
The hardest part of selling is being objective about price. That’s exactly why you need an honest, professional valuation before you start. Our property valuation service gives you the market reality – not what you want to hear, but what buyers are actually prepared to pay.
2. Forgetting That First Impressions Count (A Lot)
You know the saying about never getting a second chance to make a first impression? It’s never more true than when selling your home.
If you imagine yourself being a buyer, you visit a house and the garden is a bit wild, there is an old rusty bike by the front door and the paintwork looks old and flaky – you have already mentally reduced your offer before you have even entered the house. Or worse, you have already decided its “not the one”.
It may seem harsh, but people make emotional decisions about homes within the first few minutes.
Small changes that make a big difference:
- A fresh coat of paint on the front door (honestly, it works wonders)
- Tidy up the garden - even if you're not a gardener, neat and simple beats overgrown
- Pack away family photos and personal items - buyers need to imagine their own family here
- Make sure every room has natural light streaming in
- Fix that dripping tap or squeaky door you've been meaning to sort for months
You don’t need to spend thousands. You just need to help buyers see the potential rather than the work.
3. Choosing Your Estate Agent for the Wrong Reasons
Pricing is absolutely crucial when selling as is, and it’s where many sellers get tripped up. You need to put yourself in a buyer’s shoes – they’re taking on risk and extra work, so they expect the price to reflect that.
This one’s close to our hearts because we see the aftermath regularly. Sellers choose their agent based on the highest valuation (see point 1!) or the lowest commission, then wonder why nothing happens.
We once had a seller come to us after six months with another agent. Their previous agent had valued the property £30,000 above market value, taken stunning photos of the garden but somehow missed photographing the beautiful kitchen, and hadn’t sold a single property in the area for over a year.
Red flags when choosing an agent:
- They're the only one giving you the valuation you want to hear
- Their marketing looks like it's from 2005
- They can't show you recent sales in your area
- You get the feeling they're just saying what you want to hear
Your estate agent should feel like a trusted adviser, not a yes-person. They should challenge you when needed, guide you through the process, and demonstrate they know your local market inside out. Our experienced team has been doing exactly this for over three decades – we’ll tell you the truth, even when it’s not what you want to hear.
5. Skimping on Marketing (Then Wondering Why Nobody Calls)
In 2025, your house is competing with hundreds of others online. If your photos look like they were taken on a flip phone from 2008, or your property description reads like a shopping list, buyers will scroll straight past.
We regularly see properties with photos so dark you can’t tell if there’s furniture in the room, or descriptions that mention “three bedrooms” but forget to mention the stunning view or newly fitted kitchen.
Professional photography isn’t an optional extra – it’s essential. Most buyers decide whether to book a viewing based solely on your online photos. Poor photos mean no viewings. No viewings mean no sale.
Your estate agent should provide high-quality photography, detailed floorplans, and descriptions that actually make people want to visit. If they’re not delivering this as standard, find someone who will.
6. Leaving Legal Preparation Until the Last Minute
Nothing kills buyer enthusiasm quite like delays. You’ve found a buyer, agreed a price, then suddenly everything grinds to a halt because you can’t find the building regulations certificate for that extension you built five years ago.
Smart sellers get organised before marketing begins. It’s not exciting, but having your paperwork ready shows buyers (and their solicitors) that you’re serious and professional.
Get these sorted early:
- Energy Performance Certificate (EPC) - you'll need this anyway
- Property deeds and any lease information
- Planning permissions and building regulations certificates
- Guarantees for any major work you've had done
Being prepared prevents those frustrating delays that can cost you a sale.
7. Digging Your Heels In Over Completion Dates
Your buyer loves your house, they’ve made a good offer, but they need to complete in eight weeks and you were hoping for twelve. Do you really want to lose a good sale over four weeks?
Buyers aren’t trying to be difficult – they often have their own chains, work commitments, or children starting new schools. Sellers who can be flexible on timing often find they can negotiate better prices in return.
Obviously, you have your own circumstances to consider, but a bit of flexibility can be the difference between a sale and starting over.
Why Experience Matters When Selling Your Home
We know how frustrating it is to watch other houses in your street sell while yours sits on the market. The truth is, avoiding these mistakes isn’t something you have to figure out alone.
Since 1989, we’ve been helping families across Buckinghamshire, Bedfordshire, and Hertfordshire sell their homes successfully. Over the years, we’ve learned that every seller’s situation is unique, but the principles that lead to quick, successful sales remain the same.
We’ll give you an honest valuation based on what’s actually happening in your local market right now – not what happened six months ago or what you might hope for. Our professional photography captures your home at its absolute best, and we’ll keep you updated every step of the way so you never have to wonder what’s happening with your sale.
With offices in Bletchley, Hemel Hempstead, Milton Keynes, and Tring, our team knows what buyers are looking for in your specific area. More importantly, we know how to present your home so it stands out for all the right reasons.

Frequently Asked Questions
How long should it realistically take to sell my house?
If you’ve got your price right and your home’s looking its best, you should start getting viewing requests within a couple of weeks. The whole process from marketing to completion usually takes 8-12 weeks, though this can vary depending on your local area, the season, and whether you’re dealing with a chain.
What's the biggest mistake sellers make with pricing?
Falling in love with a figure that just doesn’t match what’s happening in the market right now. Look, we get it – you’ve invested in your home and you remember what you paid. But buyers are comparing your house to what else is available today, and if you’re even 5% above market value, you could be waiting months longer than necessary.
Should I accept the first offer that comes in?
That’s always a tricky one. If someone’s made an offer very quickly, it might mean you’re priced below market value – especially if you haven’t had many viewings yet. On the flip side, don’t dismiss a reasonable offer just because it’s first. Think about the buyer’s situation, whether they’re in a chain, and what your own timescales look like.
How much difference does professional photography really make?
It’s absolutely crucial. Nearly all buyers start their search online these days, and if your photos are dark or blurry, they’ll scroll straight past without a second thought. We’ve seen good photography boost viewing requests by 30-40% compared to basic phone snaps – it really is that important.
What should I do if my house hasn't sold after a month?
Don’t panic, but don’t ignore it either. Have an honest look at how many viewing requests you’re getting – if it’s very few, that’s usually a price issue. If you’re getting viewings but no offers, listen to the feedback. Sometimes a small price tweak or a bit of tidying up can make all the difference. And don’t be afraid to have an honest chat with your agent about changing the approach.
