Whether you’re at the very start of your mortgage journey or simply trying to get clearer on how it all works, this guide is designed to give you a confident, practical starting point.
Buying your first home can feel like a big leap. There are lots of opinions, lots of moving parts, and a lot of unfamiliar language. The good news is that the process becomes far more manageable once you break it into stages.
Start with Your “Why”
Before you get into rates, deposits and lender criteria, take a step back and get clear on what you’re trying to achieve.
Are you buying for stability after renting? Do you want space to grow into? Are you choosing location over size, or the other way around? Once you’re clear on your priorities, it’s easier to filter properties and avoid getting pulled in too many directions.
Finding the Right Property
This is likely to be one of the largest purchases you’ll ever make, so it’s worth taking your time early on.
Look at enough properties to understand what your budget realistically buys in your chosen areas. Often, a small change in location can shift affordability meaningfully. It can also change what you get for your money, especially when you compare flats, terraces and newer builds side by side.
Try to keep a simple shortlist of what matters most, and what is “nice to have”. That stops the search becoming emotional noise.
Understanding Loan-to-Value (LTV)
LTV is one of the key building blocks of a mortgage. It’s simply the relationship between your deposit and the value of the property.
If a property costs £100,000 and you put down a £5,000 deposit, that’s a 95% LTV mortgage (because you’re borrowing £95,000).
In most cases, the bigger your deposit, the more choice you tend to have. A lower LTV usually reduces the lender’s risk, which can mean better pricing and more flexibility.
If you’re looking at a 5% deposit and thinking it feels like a long road, that’s common. It does not mean you have no options, but it does mean planning matters.
Affordability: What Lenders Actually Look At
People often hear the “4.5 times income” rule and treat it as a promise. In reality, it’s only a rough guide, and the final figure will depend on the lender and your wider profile.
Lenders will look at income, but also at outgoings and commitments. Your monthly costs matter. So does the length of the mortgage term, and whether you fix for two years or five.
Broadly:
- If you’re employed, lenders typically assess basic salary and may include bonuses, commission and overtime depending on consistency and evidence.
- If you’re self-employed, lenders will usually want accounts or tax calculations, often over two years. Some will consider one year, but choice can be narrower.
- Other income can sometimes be used, but it depends on what it is and how it’s evidenced.
They’ll also factor in existing credit commitments, dependants, and how the mortgage would look if rates moved.
Why Speaking to a Broker Can Help Early
A broker isn’t a lender. They help you find the right lender and the right product for your circumstances.
The value is often in the filtering. A good broker will look at your income type, deposit, credit profile, and goals, then steer you towards lenders whose criteria genuinely fit. That can reduce wasted applications and make the process feel far less trial-and-error.
They can also help you get a Decision in Principle (DIP). It’s not a full mortgage offer, but it’s an early indicator that a lender is willing to consider you, subject to valuation and underwriting.
One point that matters here: transparency helps. If there are any credit issues or unusual circumstances, it’s better to address them upfront. It tends to make outcomes smoother, not harder.
Making an Offer and Moving to Full Application
Once you’ve got a DIP, you can make offers with more confidence, because you have a clearer sense of what’s realistic.
When your offer is accepted, the mortgage application becomes more formal. At this stage, the lender will typically assess documents, run affordability checks, and value the property.
This is also where timing starts to matter. If you want to complete by a certain date, you’ll need to factor in things like conveyancing, survey timing, and whether you’re in a chain.
Schemes and Support for First Time Buyers
There are various schemes and lender-led propositions that can help first time buyers, but they are not one-size-fits-all.
Some reduce deposit pressure, some support affordability, and some are designed for certain property types (including new builds). The key is making sure the scheme fits your longer-term plan, not just the short-term goal of “getting approved”.
Term, Rate Type, and Repayment Method
These choices shape how your mortgage behaves over time.
A longer term can reduce monthly payments, but you usually pay more interest overall. A shorter term often costs more month to month, but reduces total interest.
Fixed rates offer payment stability for the fixed period. Variable rates can move up or down, which can suit some buyers, but it comes with uncertainty.
Most first time buyers choose repayment mortgages, where you pay down both interest and capital over time. Interest-only tends to be more niche and comes with stricter requirements, plus a need for a credible repayment plan at the end.
Overpayments and Flexibility
Many mortgages allow overpayments, often up to a set annual limit without penalty. If your budget has some headroom, this can be a useful way to reduce the mortgage balance faster and build equity sooner.
The detail varies by lender, so it’s worth checking early if flexibility matters to you.
Fees and Upfront Costs
It’s easy to focus only on the deposit, but there are other costs that can catch buyers out if they’re not planned for.
Typical costs can include:
- Solicitor / conveyancing fees
- Surveys (depending on the level you choose)
- Moving costs
- Lender product fees (on some deals)
A product fee can sometimes lower the interest rate, but it isn’t automatically “worth it”. It depends on the loan size, how long you plan to keep the product, and whether the saving outweighs the fee.
Conclusion
Buying your first home is a major milestone, but it doesn’t need to feel chaotic. If you get clear on your goal, understand the basics of LTV and affordability, and approach the process in stages, you can move forward with far more confidence.
