What is a First-Time Buyer Mortgage?

A first-time buyer mortgage is simply a home loan designed for people who have never owned a property before. The eligibility rules are the same as standard mortgages – lenders look at your income, outgoings, and credit history – but there are a few key differences:

  • Lower deposit options: Many lenders accept as little as 5–10% deposit.
  • Government support: Schemes like the Mortgage Guarantee Scheme or Lifetime ISA bonuses are tailored to first-time buyers.
  • Stamp duty relief: You may pay less tax on your purchase compared to someone who has owned before.

These mortgages can make buying your first home more affordable, but comparing deals carefully is important as rates and terms vary widely. As mentined previousily, once you understand the process and get the right guidance like finding a mortgage broker near you – it becomes far less daunting.

How Much Deposit Do You Need for a First-Time Buyer Mortgage?

Most first-time buyers aim for 10% of the property value as a deposit. That means £20,000 on a £200,000 home. However, 5% deposit mortgages are widely available, especially with government support.

Deposit tiers to consider:

  • 5% deposit (95% mortgage): Easiest entry point, but rates can be higher.
  • 10% deposit (90% mortgage): Unlocks more lenders and better rates.
  • 20% deposit (80% mortgage): Usually gets you the most competitive deals.

If you’re saving for your first home, a Lifetime ISA can boost your deposit – the government adds 25% to what you save (up to £1,000 bonus per year).

"The biggest breakthrough for first-time buyers often comes when they see the whole process mapped out clearly, it suddenly feels achievable rather than overwhelming." – Will Sharman

Do First-Time Buyers Pay Stamp Duty in the UK?

First-time buyers benefit from stamp duty relief, which reduces or eliminates this cost on lower-priced homes. As of 2025:

  • 0% on the first £300,000
  • 5% on the portion from £300,000 to £500,000
  • Normal rates apply if the property is over £500,000

Example: Buying at £350,000 means you pay 0% on the first £300,000, then 5% on £50,000 – a total of £2,500.

This relief is only available if you’ve never owned property before and the home will be your main residence.

How Long Does the First-Time Buyer Mortgage Process Take?

From start to finish, most first-time buyers complete in 8–12 weeks, though this depends on the property chain and how prepared you are. A typical timeline:

  1. Mortgage in Principle (MIP): 1–3 days
  2. Property search & offer accepted: Variable – can be weeks or months
  3. Full mortgage application: 1–2 weeks
  4. Valuation & underwriting: 2–4 weeks
  5. Solicitor checks & searches: 6–8 weeks (overlaps with mortgage process)
  6. Exchange & completion: 1–2 weeks after approval

Being organised with documents, ID, and deposit ready can save weeks off the process.

Mortgage Options for First-Time Buyers: Fixed, Tracker & Variable

Choosing the right type of mortgage is just as important as saving your deposit. The main options you’ll see as a first-time buyer are fixed-rate, tracker, and variable-rate mortgages – each works differently and suits different needs.

Fixed-Rate Mortgages

A fixed-rate mortgage keeps your interest rate the same for a set period, usually two to five years. This means your monthly repayments won’t change, making it easier to budget and plan ahead. Fixed rates are popular with first-time buyers who want certainty, especially in a market where rates may rise.

Tracker Mortgages

Tracker mortgages follow the Bank of England base rate, so your payments can go up or down depending on market changes. They sometimes start lower than fixed deals, but you’ll need to be comfortable with the possibility of fluctuating payments.

Variable-Rate Mortgages

A variable-rate mortgage is set by the lender and can change at any time. Most people end up on a variable rate once their fixed or tracker deal ends. These are rarely the cheapest option, which is why many buyers remortgage before reaching this stage.

How to Decide Which Mortgage is Best for You

The right choice depends on your priorities – whether that’s predictable monthly costs or flexibility to take advantage of falling rates. If you’re unsure, speaking to a broker can help you compare deals across the market and work out what’s best for your situation.

Common Mistakes First-Time Buyers Make (and How to Avoid Them)

Buying your first home is exciting, but it’s easy to make mistakes when you’re unfamiliar with the process. We see these issues regularly when helping clients – and avoiding them can save you time, money and stress.

Overstretching Your Budget

It’s tempting to borrow the maximum amount a lender offers, but this can leave little room for everyday expenses or future changes in circumstances. Aim for a mortgage that feels comfortable, not just one you can technically afford. A broker can help you work out a realistic figure based on your income and lifestyle.

Forgetting About Extra Costs Beyond the Deposit

Your deposit is only part of the picture. Legal fees, stamp duty, surveys, insurance, and moving costs can add thousands to your total spend. Planning for these costs upfront means fewer surprises when completion day arrives.

Rushing Into an Offer

Falling in love with the first property you see can lead to regrets later. Always view a property more than once, ideally at different times of day, and check for things like noise levels, parking, damp, and local amenities. A little patience can make a big difference to long-term satisfaction.

Skipping a Mortgage in Principle

A Mortgage in Principle (MIP) shows estate agents and sellers that you’re serious – and it speeds up the process once you make an offer. Without it, you risk missing out on properties to better-prepared buyers.

Not Comparing Lenders Properly

Going straight to your bank might seem easier, but it limits your options. Whole-of-market brokers compare deals across multiple lenders, often finding rates or products that aren’t advertised to the public. This can save thousands over the life of your mortgage.

Pro Tip: If you’re unsure about any stage of the process, speak to a broker early. The right advice upfront can prevent costly mistakes later.

First-Time Buyer Mortgage Process: Step-by-Step Guide

Here’s a simplified roadmap for your first home purchase:

  1. Check affordability – Use a mortgage calculator or speak to a broker to set your budget.
  2. Save your deposit – Aim for at least 5–10% of the purchase price.
  3. Get a Mortgage in Principle – Shows estate agents and sellers you’re serious.
  4. Start viewing properties – Compare locations, property types, and condition.
  5. Make an offer – Negotiate based on market data and property condition.
  6. Appoint a solicitor – They handle contracts, searches, and legal checks.
  7. Submit full mortgage application – Broker helps prepare paperwork.
  8. Valuation and approval – Lender confirms property value and issues offer.
  9. Exchange contracts – Legally binding stage; pay deposit to solicitor.
  10. Completion day – Funds transfer, keys collected – you’re officially a homeowner.

Tips for Getting Approved Quickly

  • Organise documents early – payslips, bank statements, ID, proof of deposit.
  • Avoid new borrowing – lenders prefer stable finances in the months before applying.
  • Use a whole-of-market broker – they compare deals and manage applications, reducing delays.
  • Get pre-approved before house hunting – speeds up offers and negotiations.

FAQs About First-Time Buyer Mortgages

What credit score do I need to buy my first home?
Most lenders want to see a clean credit history with timely payments. Exact score requirements vary, but stronger credit usually means better rates.

Can I buy with a friend or partner?
Yes, you can apply for a joint mortgage. Your combined income boosts affordability, but you’ll be jointly responsible for repayments.

Is Shared Ownership worth it?
It can lower entry costs, but consider long-term costs like rent on the unsold share and potential restrictions on selling.

Do I need a survey?
Yes, even for new builds. A basic survey can flag major issues, while more detailed ones give peace of mind on older properties.

Can I buy my council house with no deposit?

If you’re a council tenant wondering whether you need a deposit to buy your home, the answer is often no. With the Right to Buy scheme, many lenders allow the council discount to be used as your deposit, meaning you can purchase your property without putting down cash savings. While affordability, credit history, and property type still matter, the right advice can make the difference between thinking homeownership is out of reach and actually making it happen.
