Your Journey to Homeownership Starts Here

Buying your first home is one of the most exciting milestones in life β€” but it can also feel overwhelming. From understanding mortgage types to navigating the application process, there is a lot to take in. At Nationwide Building Society, we have been helping first-time buyers get on the property ladder since 1884, and as a member-owned mutual, our priority is always your best interest rather than shareholder profits.

This comprehensive guide walks you through every step of the mortgage process, so you can approach your first purchase with confidence and clarity.

How Much Can You Borrow?

Before you start browsing property listings, it is essential to understand your borrowing capacity. Lenders typically consider your income, outgoings, credit history, and the size of your deposit. As a general rule, most lenders will offer between 4 and 4.5 times your annual household income.

Nationwide's free mortgage calculator helps you estimate how much you could borrow and what your monthly repayments might look like. Remember, a larger deposit usually means better interest rates and lower monthly payments. Aim for at least 10% of the property's value, though some schemes allow as little as 5%.

Understanding Mortgage Types

Choosing the right mortgage type is crucial. Here are the main options available:

  • Fixed-rate mortgages β€” Your interest rate stays the same for a set period, typically two to five years. This gives you certainty over your monthly payments and protection against rate rises.
  • Tracker mortgages β€” Your rate moves in line with the Bank of England base rate. Payments can go up or down, but you benefit when rates fall.
  • Variable-rate mortgages β€” The lender sets the rate, which can change at any time. These offer flexibility but less certainty.
  • Offset mortgages β€” Your savings are offset against your mortgage balance, reducing the interest you pay.

Nationwide offers a range of competitive fixed-rate and tracker mortgages specifically designed for first-time buyers, with dedicated support throughout the process.

Government Schemes for First-Time Buyers

Several government initiatives can help you get on the property ladder more quickly:

  • Lifetime ISA (LISA) β€” Save up to Β£4,000 per year and receive a 25% government bonus towards your first home.
  • Shared Ownership β€” Buy a share of a property (25-75%) and pay rent on the rest, with the option to buy more later.
  • First Homes scheme β€” Provides a minimum 30% discount on new-build homes for eligible first-time buyers.
  • Mortgage Guarantee Scheme β€” Enables lenders to offer 95% mortgages with a government guarantee, meaning you need only a 5% deposit.

The Application Process Step by Step

Once you have found a property and had an offer accepted, the mortgage application process typically follows these stages:

  1. Agreement in Principle (AIP) β€” A preliminary check that confirms how much a lender is willing to offer you.
  2. Full application β€” Submit detailed financial information including payslips, bank statements, and identification.
  3. Valuation β€” The lender arranges a valuation of the property to ensure it is worth the purchase price.
  4. Mortgage offer β€” If everything checks out, you receive a formal mortgage offer.
  5. Exchange and completion β€” Your solicitor handles the legal transfer, and you receive the keys to your new home.

Costs Beyond the Deposit

First-time buyers should budget for additional costs including solicitor fees (Β£1,000-Β£2,000), survey costs (Β£250-Β£700), and moving expenses. The good news is that first-time buyers in England and Northern Ireland pay no stamp duty on properties up to Β£425,000.
