Mortgage Deals for First -Time Buyers.

Buying your first home in London can feel overwhelming. Between rising property prices, changing interest rates and endless mortgage options, it’s easy to get stuck not knowing where to start.

The good news is, once you understand how mortgage deals actually work, everything becomes a lot clearer.

This guide breaks down the key things you need to know so you can move forward with confidence.

How lenders price mortgage deals

When you take out a mortgage, you’re borrowing money from a lender and paying interest on that loan.

While the Bank of England base rate plays a big role in where mortgage rates sit, it’s not the only factor. Lenders will also assess:

• Your income and employment type
• Your credit profile
• Your existing commitments
• The size of your deposit

On top of that, wider market conditions can impact pricing. We’ve seen recently how quickly rates can shift based on global events or economic changes.

The key point is this: the rate you’re offered is tailored to you, not just the market.

Rate vs product fee – what actually matters?

One of the most common mistakes first-time buyers make is focusing purely on the interest rate.

Most mortgage products come with an arrangement fee, typically ranging from a few hundred pounds to around £1,000.

Generally:
• Lower rates tend to come with higher fees
• Higher rates often come with lower or no fees

The “best” deal isn’t always the lowest rate – it’s the one that works out cheapest overall based on your loan size and how long you’ll keep the mortgage.

This is where advice really matters, because the difference can be thousands over time.

How your deposit impacts your rate

Your deposit determines your loan-to-value (LTV), which is one of the biggest drivers of your mortgage rate.

Put simply:
• Bigger deposit = lower risk to the lender
• Lower risk = better rates available

For example:
• 90% LTV (10% deposit) will have higher rates
• 75% or 60% LTV unlocks much more competitive pricing

In London, where property prices are higher, even moving up one LTV band can make a noticeable difference to your monthly payments.

Buying in London as a first-time buyer

London is a different market altogether.

Higher property values mean:
• Larger deposits are often needed
• Affordability can be stretched
• Lenders scrutinise applications more closely

That said, lenders are also used to London buyers and will take a more flexible view on income multiples in many cases.

With the right structure, first-time buyers can often borrow up to 5.5x income, depending on the lender and overall profile.

Types of mortgage deals explained

Fixed rate mortgages

A fixed rate means your interest rate stays the same for a set period, usually 2, 3 or 5 years (sometimes longer).

This gives you:
• Certainty on your monthly payments
• Protection from interest rate increases

At the end of the fixed period, you’ll either remortgage or move onto your lender’s standard variable rate.

For most first-time buyers, this is the most popular option as it offers stability.

Variable rate mortgages

With a variable rate, your interest rate can go up or down over time.

This means:
• Your payments could decrease if rates fall
• But they could also increase if rates rise

These products can be useful in certain scenarios, but they come with less certainty, which doesn’t suit everyone.

Standard variable rate (SVR)

This is the lender’s default rate.

It’s typically higher than fixed or tracker deals and is what you move onto if you don’t switch at the end of your initial deal.

In most cases, you’ll want to avoid sitting on SVR longer than necessary.

Tracker mortgages

Tracker mortgages follow the Bank of England base rate, plus a set percentage.

For example:
Base rate + 1%

So if the base rate changes, your mortgage rate changes too.

These can work well in the right market conditions but come with the risk of rising payments.

Discount mortgages

These offer a discount off the lender’s SVR for a set period.

They can look attractive initially, but because they’re linked to the lender’s variable rate, your payments can still change.

Offset mortgages

Offset mortgages allow you to link your savings to your mortgage.

Instead of earning interest on your savings, they reduce the amount of mortgage interest you pay.

These can be very effective for higher earners or those with significant savings, but they’re not always the right fit for everyone.

How to compare mortgage deals properly

Looking at comparison sites can give you a rough idea of what’s out there, but they rarely tell the full story.

Key things to consider:

• What will the deal cost over the full term, not just the headline rate?
• How long do you plan to stay in the property?
• Do you need flexibility to overpay or move?
• Are there early repayment charges?
• How will the lender assess your income and circumstances?

The reality is, the “best rate” on paper isn’t always the best deal in practice.

A good broker doesn’t just find you a rate – they build the right strategy around your situation.
