Buying a House on the Open Market
This complete guide explains everything buyers need to know, from working out what you can afford and securing a mortgage to understanding surveys, making offers, and budgeting for hidden costs.
Buying a property is one of the biggest financial decisions most people will ever make. Whether you are a first-time buyer, moving into a larger home, downsizing, or investing in property, understanding the buying process is essential in 2026’s housing market.
The UK property market has continued to evolve over the last few years, with higher living costs, fluctuating mortgage rates, stricter affordability checks, and growing demand in certain areas all affecting how buyers approach purchasing a home. While buying a property can feel overwhelming at first, being informed about your finances, mortgage options, surveys, legal costs, and the offer process can make the experience significantly less stressful.
There are many elements of buying a house that people often overlook. From understanding how much you can realistically afford to knowing what questions to ask an estate agent, careful preparation can help you avoid costly mistakes later.
This 2026 guide covers everything you need to know before buying a property, including:
- How to work out what you can afford
- What mortgage lenders assess
- Why mortgage applications get declined
- How much deposit you may need
- What to ask estate agents and sellers
- The hidden costs of buying a house
- Homebuyer surveys explained
- Key trends affecting buyers in 2026
By understanding the full buying process before you begin, you’ll be in a far stronger position to secure the right property at the right price.
How do I know what house I can afford?
One of the first steps when buying a property is understanding exactly what you can afford. In 2026, mortgage lenders will continue to apply detailed affordability assessments to ensure buyers can comfortably manage their repayments even if interest rates rise further.
A good place to start is by using an online mortgage affordability calculator. Most lenders and comparison websites provide these calculators free of charge, and they can help give you a rough estimate of how much you may be able to borrow.
To complete an affordability calculation, you will usually need:
- Your annual salary before tax
- Your monthly take-home income
- Any additional income, such as bonuses, benefits, freelance work, or child maintenance
- Your monthly expenses
- Existing debts and credit commitments
- Household bills and living costs
- Childcare or maintenance payments
- Travel and commuting costs
Mortgage lenders in 2026 are placing even more focus on disposable income rather than simply applying a multiple to your salary. This means your spending habits, debt levels, and monthly commitments can significantly affect how much you can borrow.
While affordability calculators are useful, they are only estimates. Your actual mortgage offer may differ depending on the lender’s criteria, your credit history, the size of your deposit, and current market conditions.
It’s also important to avoid stretching your budget too far. Just because a lender is willing to approve a certain amount does not necessarily mean it is financially comfortable long-term. Buyers should consider future expenses, rising energy costs, maintenance, and unexpected financial changes before committing.
What will my mortgage lender assess in 2026?
Mortgage lenders carefully examine your financial situation before approving a mortgage application. Since interest rates and living costs remain higher than pre-2020 levels, lenders are continuing to apply stricter affordability checks in 2026.
Some of the main factors lenders assess include:
Your income
Lenders will review your salary, bonuses, overtime, commissions, and any secondary income. If you are self-employed, they will usually request at least two years of accounts or tax returns.
Your monthly expenditure
Your regular spending is now scrutinised more closely than ever. Lenders want to ensure you can comfortably afford repayments after covering essential living costs.
This may include:
- Rent payments
- Utility bills
- Credit card repayments
- Loans and finance agreements
- Insurance
- Food and transport costs
- Childcare expenses
- Subscription services
Your credit history
Your credit score remains one of the most important parts of a mortgage application. Lenders check whether you have:
- Missed payments
- Defaults or CCJs
- Excessive borrowing
- Payday loans
- High credit utilisation
- Recent credit applications
Your deposit size
A larger deposit generally improves your chances of approval and can help secure better mortgage rates.
Employment stability
Lenders prefer stable employment. Buyers who frequently change jobs or have inconsistent income may face additional checks.
Stress testing
Mortgage providers continue to stress test applications in 2026 to ensure borrowers could still afford repayments if interest rates increase further in the future.
How much deposit do I need to buy a house?
The minimum deposit required for a mortgage in the UK is typically 5% of the property value, although many lenders prefer buyers to have at least 10%.
The size of your deposit directly affects:
- The mortgage deals available to you
- Your interest rate
- Your monthly repayments
- Your chances of approval
For example:
- 5% deposit = 95% mortgage
- 10% deposit = 90% mortgage
- 15% deposit = 85% mortgage
- 20%+ deposit = access to more competitive rates
In 2026, mortgage rates are generally more favourable for buyers with larger deposits because lenders view them as lower risk.
Example
If you purchase a property worth £250,000:
- A 5% deposit would be £12,500
- A 10% deposit would be £25,000
- A 20% deposit would be £50,000
First-time buyers may also benefit from certain government-backed schemes or specialist mortgage products depending on eligibility.
You should also remember that your deposit is not the only upfront cost. Legal fees, surveys, moving costs, and stamp duty may all need to be paid separately.
Why has my mortgage application been declined?
Mortgage applications can be rejected for many reasons. Some are easily resolved, while others may require more preparation before reapplying.
Here are some of the most common reasons mortgage applications are declined in 2026.
1. Poor credit history
Your credit score plays a major role in mortgage approval.
Late payments, defaults, County Court Judgments (CCJs), or excessive debt can reduce your chances significantly.
Before applying, check your credit report with agencies such as Experian, Equifax, or TransUnion.
2. Too many recent credit applications
Applying for several loans or credit cards within a short period can raise concerns for lenders.
Multiple applications may suggest financial difficulty or reliance on borrowing.
3. High debt levels
Large amounts of outstanding debt reduce affordability and can lead to rejection.
Lenders consider:
- Credit cards
- Personal loans
- Car finance
- Buy now, pay later agreements
- Overdraft usage
4. Payday loan history
Even if repaid on time, payday loans can negatively affect mortgage applications because lenders may view them as a sign of financial instability.
5. Small deposit
The smaller your deposit, the higher the lender’s risk.
If your deposit is too low, some lenders may reject the application or offer less competitive rates.
6. Unstable employment
Frequent job changes or inconsistent income may cause lenders to question affordability.
7. Self-employment complications
Self-employed applicants usually need:
- Two or more years of accounts
- SA302 tax calculations
- Business bank statements
- Proof of future income stability
8. Errors on your credit file
Administrative mistakes can happen.
Old addresses, incorrect defaults, or fraudulent activity may negatively affect your score.
9. Not being registered on the electoral roll
Being registered to vote helps lenders verify your identity and address history.
10. Affordability concerns
Even applicants with good salaries can be rejected if their outgoings are considered too high.
What do I need to know before making an offer on a house?
Once you’ve found a property you like, it’s important to approach the offer process carefully.
Before making an offer, you should:
- Understand your maximum budget
- Have a mortgage agreement in principle
- Research local property prices
- Understand current market conditions
- Learn more about the seller’s circumstances
- Review the property’s condition
- Check transport links and local amenities
In 2026, buyers are continuing to face competition in many areas, especially for homes that are energy efficient, chain-free, or close to transport links.
Properties that require substantial renovation may take longer to sell, which can provide opportunities for negotiation.
What should I ask the estate agent?
Estate agents can provide valuable information about both the property and the seller.
Here are some important questions to ask.
Why is the owner selling?
Understanding the seller’s motivation can help you negotiate.
If they need a quick sale due to relocation, divorce, or financial reasons, they may be more open to lower offers.
How long has the property been on the market?
Properties that remain unsold for long periods may:
- Be overpriced
- Have hidden issues
- Be in less desirable areas
- Require renovation
Longer listing times can create negotiation opportunities.
Have there been many viewings or offers?
This gives insight into competition.
High interest could mean you need to act quickly.
Have the sellers found another property?
If the seller has already secured their next home, they may be more motivated to move forward quickly.
What is the minimum price the seller would consider?
Many buyers forget to ask this question, but it can reveal useful information about the seller’s expectations.
Are there any known issues with the property?
Ask directly about:
- Damp
- Subsidence
- Flood risk
- Boundary disputes
- Roofing problems
- Boiler issues
What are the neighbours and area like?
While agents may not reveal every negative detail, they can often provide useful local insights.
Can I offer below the asking price?
Yes and in many cases, buyers do.
Whether a lower offer is accepted depends on:
- Market conditions
- Seller motivation
- Property condition
- Competing offers
- How long the house has been listed
You may have stronger negotiating power if you:
- Are chain-free
- Are a cash buyer
- Already have a mortgage agreed in principle
- Can move quickly
- Have identified repairs or structural issues
- Are buying a property that has been listed for a long time
However, in highly competitive areas, significantly lower offers may be rejected immediately.
Researching comparable sold prices nearby can help you make a realistic offer.
How can I make myself more appealing to sellers?
Sellers want buyers who are financially secure and unlikely to cause delays.
You can make yourself more attractive by:
Being chain-free
Chain-free buyers are often preferred because there is less risk of the transaction collapsing.
Having a mortgage agreement in principle
This shows sellers you are financially prepared.
Being flexible with dates
Flexibility can help sellers coordinate their onward move.
Using an experienced solicitor
A proactive conveyancer can help reduce delays.
Responding quickly
Delays in paperwork or communication can frustrate sellers and risk losing the property.
What should I ask before buying a house?
Before committing to a purchase, make sure you fully understand the property.
What is included in the sale?
Ask whether fixtures, fittings, appliances, curtains, or garden items are included.
Has the property experienced issues before?
Properties may have a history of:
- Flooding
- Damp
- Structural movement
- Roof leaks
- Pest problems
Knowing this early can save you from future expenses.
How old are the boiler and electrics?
Replacing major systems can be expensive.
Ask about:
- Boiler age
- Electrical rewiring
- Plumbing updates
- Roof replacement
Has the property been renovated or extended?
If work has been completed, confirm:
- Planning permission was obtained
- Building regulations were followed
- Guarantees or warranties exist
What are the running costs?
Rising energy bills remain a major concern in 2026.
Ask about:
- Utility bills
- Council tax
- Service charges
- Ground rent
- Insurance costs
Is the property energy efficient?
Energy efficiency has become increasingly important.
Check:
- EPC rating
- Insulation
- Double glazing
- Heating system efficiency
- Solar panels or heat pumps
Homes with poor EPC ratings may be more expensive to run and harder to mortgage in the future.
What is the local area like?
Visit the area at different times of day to assess:
- Traffic
- Noise
- Parking
- Safety
- Public transport
- Local amenities

Buildings insurance is usually required by mortgage lenders.
Contents insurance is optional but strongly recommended.
What are the different homebuyer surveys?
Surveys are one of the most important parts of buying a property.
