What I Wish Every First-Time Buyer Knew Before Applying for a Mortgage
Written by Oliver Smith, Mortgage Broker
Last reviewed: October 2026
If I could sit down with every first-time buyer six months before they started looking at properties, there are a few things I would want them to know.
Not because buying your first home needs to be complicated.
Quite the opposite.
A lot of the stress comes from discovering things too late.
You find the house before understanding what you can comfortably borrow.
You put every pound into the deposit and forget about the costs afterwards.
You worry that having car finance means you cannot get a mortgage.
Or you spend weeks trying to make your finances look “perfect” without knowing whether the things you are changing actually matter.
Hi, I’m Oliver. I’m a mortgage broker based in Sale, helping first-time buyers across Trafford and further afield understand their options.
These are some of the things I wish every first-time buyer knew before they applied for their first mortgage.
1. Speak to a Mortgage Broker Before You Fall in Love With a House
This is probably the first thing I would change.
A lot of people approach the process like this:
Find house → make offer → panic about mortgage.
I would rather it looked more like:
Understand finances → establish sensible budget → start viewing → make offer.
You don't necessarily need a property before having an initial mortgage conversation.
We can look at your:
Income.
Deposit.
Existing debts.
Monthly commitments.
Approximate mortgage borrowing.
Likely monthly repayments.
That can give you a realistic range before you start spending Saturday afternoons viewing houses you may not actually want — or cannot comfortably afford.
MoneyHelper also recommends understanding what you can afford before starting your property search and notes that mortgage affordability depends on both income and monthly expenditure.
2. The Maximum Mortgage Is Not Your Target
This is one of the biggest things I want first-time buyers to understand.
Suppose a lender could potentially allow you to borrow £325,000.
That does not automatically mean “I should borrow £325,000.”
It means that under that lender's assessment, the borrowing may potentially be available.
You still need to decide whether you actually want that level of mortgage.
There is a big difference between what the lender might approve and what feels comfortable to you every month.
You may want money left for:
Holidays.
Savings.
Pension contributions.
A car.
Social life.
Hobbies.
Future children.
Home improvements.
MoneyHelper makes the same distinction: lenders have their own affordability rules, but ultimately you still need to decide whether the mortgage is affordable now and if your circumstances change later.
3. Your Current Spending Matters
Your salary is not the only thing a lender looks at.
If two people both earn £50,000 but one has:
£500 monthly car finance.
A personal loan.
Credit-card balances.
...while the other has very few commitments, their mortgage affordability may be different.
Lenders can consider expenditure such as travel, childcare, loans, credit cards, subscriptions and normal living costs.
So when I ask about your outgoings, I am not judging them.
I need to understand them because the lender will too.
4. Car Finance Does Not Automatically Stop You Getting a Mortgage
This deserves its own section because I get why people worry about it.
You may have:
PCP.
Hire purchase.
Personal loan.
Lease commitment.
That does not automatically mean “No mortgage.”
It means the monthly commitment may affect how much you can borrow.
Before clearing a large car balance with your deposit savings, I would rather compare both scenarios.
For example:
Option A: keep £15,000 towards the house deposit and retain the car finance.
Option B: use £10,000 to clear the car and reduce the deposit to £5,000.
Depending on the mortgage, one option may work better than the other.
Don't make a major financial decision purely because somebody told you “You need to clear all debt before applying.”
Let us look at the actual numbers.
5. You Don't Need Perfect Finances to Speak to Me
Sometimes people delay the mortgage conversation because they think they need to tidy everything up first.
They say “I'll speak to you when my credit card is cleared.” or “I'll get in touch when I've saved another £10,000.”
There is nothing wrong with improving your finances.
But you may be doing work that isn't necessary.
If you speak to me earlier, we can identify what actually needs improving.
Perhaps saving another £5,000 makes a meaningful difference.
Perhaps it doesn't.
Perhaps paying down a particular debt improves affordability considerably.
Perhaps keeping the money for the deposit is more useful.
Knowing the objective can make saving much easier.
6. Check Your Credit Report Before the Mortgage Application
I would definitely do this.
Not because you need a perfect credit score.
But because it is useful to know what a lender may see.
MoneyHelper recommends checking your credit report before applying for a mortgage so you can identify mistakes and see whether missed payments or other information
could affect an application.
Look for:
Incorrect addresses.
Accounts you don't recognise.
Financial links that should no longer exist.
Missed payments.
Incorrect information.
If something is wrong, you have time to deal with it before the mortgage application.
7. Don't Panic if Your Credit History Isn't Perfect
If you do find something you are worried about, tell me.
Perhaps there was:
A missed payment.
Default.
Arrangement to pay.
Previous financial difficulty.
That does not automatically mean homeownership is impossible.
Different lenders have different criteria.
What matters can include:
What happened.
How long ago it happened.
Amount involved.
Credit history since.
Deposit.
Wider circumstances.
What I would avoid is making lots of mortgage applications hoping somebody says yes.
MoneyHelper warns that making repeated applications in a short period can affect your credit profile, so understanding the position first is much better.
8. Your Deposit Is Not the Only Money You Need
First-time buyers understandably become obsessed with the deposit.
Perhaps your goal is £20,000.
You finally reach it.
Great.
But buying the property may also involve:
Solicitor or conveyancer fees.
Survey.
Mortgage product or arrangement fees.
Insurance.
Tax where applicable.
Moving costs.
Furniture.
Initial repairs.
MoneyHelper specifically highlights survey, conveyancing, mortgage, insurance and tax costs as expenses buyers need to budget for alongside the deposit.
So if you have exactly £20,000 and the mortgage requires a £20,000 deposit, we should talk about where everything else is coming from.
9. Don't Automatically Put Every Penny Into the Deposit
This links directly to the previous point.
A larger deposit can absolutely help.
MoneyHelper says first-time buyers commonly need at least around 5% to 10%, and a larger deposit can reduce borrowing and potentially provide access to a wider range of mortgage products.
But that doesn't mean more deposit is always better at any cost.
Imagine you have: £40,000 savings. You could put the full £40,000 into the property.
Or perhaps you use £32,000 deposit and retain £8,000 for fees, furniture and emergencies.
The larger mortgage may cost more.
But the stronger cash reserve may make your first year of homeownership considerably less stressful.
We can compare the numbers rather than guessing.
10. The Day After Completion Matters Too
Getting the keys isn't the end of the financial planning.
It is the beginning of homeownership.
Suddenly you are responsible for:
Mortgage.
Council Tax.
Gas and electricity.
Water.
Broadband.
Insurance.
Repairs.
Furniture.
Maintenance.
If you are leaving your parents' home for the first time, some of these costs may be completely new.
That is why I like first-time buyers to think about “What will I have left after completion?” rather than only “Can I scrape together enough to complete?”
MoneyHelper suggests trying to build accessible savings where possible to cover unexpected changes in income and household costs.
11. A 5% Deposit Doesn't Mean You Should Automatically Buy With 5%
You may find a mortgage that allows you to purchase with a relatively small deposit.
That can be extremely useful.
But the mortgage available at 95% loan-to-value may be different from what is available at 90%.
A bigger deposit means less borrowing and may potentially improve the interest rate or product choice.
Suppose you could buy today with 5% deposit or wait another six months and reach
10%.
There is no universal answer.
Buying sooner may be more important to you.
Another buyer may prefer waiting if the financial difference is meaningful.
We can compare both.
12. An Agreement in Principle Is Not a Mortgage Offer
This is really important.
An Agreement in Principle can be useful.
It can give an initial indication of what a lender might be prepared to lend.
But it isn't the same as “The bank has approved my mortgage.”
The formal application still needs to be completed.
The lender still needs to assess:
Your full circumstances.
Supporting documents.
Credit.
The property.
So I don't want someone making a property decision based on the belief that an Agreement in Principle guarantees the final mortgage.
It doesn't.
13. The Property Has to Pass the Mortgage Test Too
You may personally be a fantastic mortgage applicant.
Good income.
Good deposit.
Good credit.
That does not mean every property is automatically acceptable to every lender.
The lender is taking the property as security.
Things such as:
Construction.
Lease length.
Location above commercial premises.
Property condition.
Unusual features.
...can potentially affect lender appetite.
This is another reason the final lender choice can depend on the property you actually find.
14. The Mortgage Valuation Is Not Your Survey
Please remember this.
The lender's valuation is primarily for the lender.
It is there to help the lender decide whether the property is acceptable security for the mortgage.
It is not necessarily somebody investigating every potential problem with the house.
If you want a more detailed assessment of the property's condition, you may need an appropriate survey.
A mortgage offer does not mean “The house is perfect.”
It means the lender has agreed to provide the mortgage under the terms of its offer.
15. You Can Negotiate on a Property
Another thing first-time buyers can feel awkward about.
An asking price is not always a fixed price.
You can make an offer.
MoneyHelper's own first-time buyer material specifically addresses this question because new buyers often wonder whether negotiating below asking price is normal.
Whether a lower offer is appropriate depends on:
Market.
Property.
Competition.
Seller.
Condition.
I'm not your estate agent and I am not going to tell you what to offer.
But I don't want you assuming the asking price is automatically the only price anybody is allowed to discuss.
16. Don't Let an Estate Agent Determine Your Mortgage Budget
Estate agents sell houses.
Your mortgage adviser helps you understand the borrowing.
Those are different jobs.
If somebody says “You could probably stretch another £25,000.” the important word is probably.
Before increasing your offer or budget, understand what that actually means to your mortgage.
An extra £25,000 purchase price might mean:
Larger deposit.
More borrowing.
Higher monthly payment.
Different LTV.
Different mortgage product.
Don't increase the budget because somebody says the property is “worth stretching for” without understanding the financial consequences.
17. Buying With a Partner Requires More Than Combining Two Salaries
A couple may have stronger affordability because two incomes are supporting the mortgage.
But I would still think about:
Who is contributing the deposit?
Are contributions equal?
What happens if one person reduces working hours?
What if you separate?
How will household costs be shared?
Some of those are legal rather than mortgage questions and should be discussed with your solicitor.
The point is that buying together is a major financial commitment.
Don't let the excitement of choosing furniture replace the more important conversations.
18. Self-Employed Does Not Mean “Hard to Mortgage”
If you are self-employed, please don't assume you need to wait until you become employed before buying.
Mortgage lenders assess self-employed income in different ways.
The documentation may be different.
MoneyHelper notes that self-employed mortgage applicants may need accounts and tax documentation as part of the mortgage application.
You might be:
Sole trader.
Company director.
Contractor.
Partner.
Tell me how your income works.
Then we can look at lenders that may suit it.
19. Get Your Documents Organised Before You Need Them
This one sounds boring.
It can save a lot of frustration.
MoneyHelper suggests preparing documents such as proof of identity, recent payslips, bank statements, deposit evidence and additional tax/accounts documentation where relevant before applying.
I would rather discover early that we need a particular statement than find out once you are under pressure because your offer has already been accepted.
Get organised early.
Future you will appreciate it.
20. Be Accurate With the Mortgage Application
Do not round your salary up.
Do not “forget” about a loan.
Do not guess figures because they sound close enough.
MoneyHelper explicitly advises applicants to ensure the information in the mortgage application matches the supporting documents they provide.
If something is complicated, tell me.
I can work with complicated.
What creates problems is inaccurate information.
21. Don't Take New Credit Without Thinking About the Mortgage
You have your deposit ready.
You're excited.
You decide to finance a new car before applying for the mortgage.
That new monthly commitment could affect affordability.
The same principle applies to:
Personal loans.
Large credit-card balances.
Buy-now-pay-later commitments.
I'm not saying first-time buyers should stop living their lives.
But if buying a property is a near-term priority, I would think carefully before taking on significant new monthly debt.
If you need to make a purchase, ask me whether it could affect the mortgage first.
22. You Don't Need to Furnish the Whole Property on Day One
This is not technically mortgage advice.
But I really wish more first-time buyers heard it.
You get the keys.
Suddenly there is a temptation to buy:
new sofa;
new television;
new dining table;
new bed;
new furniture for every room.
Some people finance all of it.
Now, immediately after taking out the largest debt of their life, they have added several more monthly commitments.
There is nothing wrong with an empty spare room.
Buy the essentials.
Live in the house.
Build your savings back up.
The rest can come later.
23. Your First Home Does Not Need to Be Your Forever Home
There can be pressure to stretch because people say “Buy as much house as you possibly can.”
I don't agree with that as a universal rule.
Perhaps a two-bedroom flat suits your life perfectly for the next five years.
There is nothing wrong with that.
Equally, if spending a little more today buys the extra bedroom that means you can stay for ten years rather than three, that may be valuable.
We wrote a separate guide on whether first-time buyers should choose a starter home or stretch for something longer-term because I think this deserves proper consideration.
Your first home should suit you.
Not somebody else's idea of what your first property should look like.
24. A Flat Can Be a Great First Home
Another misconception “A house is always better than a flat.”
Not necessarily.
A flat might give you:
Lower purchase price.
Smaller mortgage.
Better location.
Metrolink access.
Less maintenance responsibility.
But you need to check things such as:
Lease length.
Service charge.
Planned works.
Management arrangements.
Mortgageability.
Again, it is about understanding what you are buying rather than following a rule.
25. The Mortgage Rate Isn't Everything
You will naturally look at the interest rate.
So will I.
But the mortgage can also include:
Product fee.
Cashback.
Early repayment charges.
Overpayment rules.
Fixed period.
Mortgage term.
A mortgage with the lowest headline rate may not have the lowest overall cost.
And it may not provide the features that suit your plans.
That is part of what I look at when making a mortgage recommendation.
26. Think About How Long You Want the Mortgage to Run
Long mortgage terms have become more common because they can reduce the monthly payment.
But a longer term generally means paying interest for longer.
If you take a 35-year mortgage that does not mean you are trapped for 35 years.
Your circumstances may change.
You may later:
Remortgage.
Shorten the term.
Make overpayments.
Move home.
The important thing is understanding why we are choosing the term in the first place.
27. You Can Ask Me the Same Question Twice
Or three times.
Buying a house involves a lot of information.
You may completely understand something during our first meeting and then forget it once you are dealing with:
Estate agents.
Solicitors.
Surveys.
Lenders.
Removal companies.
I don't expect you to remember everything.
If you need something explaining again, ask.
28. Don't Compare Your Purchase With Your Friends'
This is more important than it sounds.
Your friend might have bought a £450,000 house at 27.
Great.
Perhaps they bought jointly.
Perhaps they had a £100,000 family gift.
Perhaps their salaries are different.
Perhaps they have no debt.
Their financial situation tells you absolutely nothing about what your first home should cost.
A £220,000 flat that you comfortably own alone could be an excellent first purchase.
Your mortgage needs to work for your finances.
29. Don't Rush Because You Feel “Behind”
There isn't an age when you are supposed to own a house.
Some people buy at 25, others at 35. Others later.
Buying a property before you are financially ready simply because everybody else seems to be doing it is not necessarily progress.
If waiting another year gives you:
Larger deposit.
Better credit.
More stable income.
Stronger emergency savings.
...then waiting may be worthwhile.
Equally, if you are ready today, there may be no reason to delay simply because you're waiting for the mythical “perfect time”.
30. Buying Your First Home Should Leave You Able to Enjoy It
This is probably the point I care about most.
I don't want someone to complete on their first property and immediately think “We cannot afford to do anything for the next five years.”
There may be periods where money is tighter.
That's normal.
But if the mortgage consumes absolutely every spare pound from day one, I would want to understand why we are stretching that far.
Your home should be somewhere you enjoy living.
The mortgage is simply the financial tool that helps you buy it.
What I Wish Every First-Time Buyer Knew
If I had to reduce everything in this article to a few points, they would be these:
Speak to someone early.
Know your comfortable budget, not only your maximum.
Don't hide financial complications.
Check your credit report.
Get your documents organised.
Budget beyond the deposit.
Keep some money back where possible.
Ask questions when you don't understand something.
And most importantly: Don't make the mortgage bigger simply because somebody says you can.
How I Approach First-Time Buyer Mortgages
My job isn't simply to find a lender willing to say yes.
I want to understand:
What you are trying to buy.
What deposit you have.
What your income looks like.
What commitments you have.
What monthly mortgage feels comfortable.
What plans you have for the next few years.
Then I can research mortgage options around your circumstances, rather than trying to fit you into whichever mortgage happens to have the lowest advertised rate that day.
Thinking About Your First Mortgage?
If you're six months away from buying, that's fine.
If you've already found the house, that's fine too.
And if you're only at the stage of wondering “Could I actually buy?” that's a perfectly good place to start.
You don't need to have the answers before speaking to me.
We can work them out.
