First-Time Buyer Mortgage Guide: Schemes, Deposits & Stamp Duty Rules

Taking your first step onto the UK property ladder is an exciting milestone, but navigating the mortgage market for the first time can feel overwhelming. First-time buyers face unique challenges, particularly around saving a deposit and passing strict lender affordability checks. Fortunately, several government-backed schemes and tax reliefs exist to help. In this comprehensive guide, we explain the minimum deposit requirements, outline available first-time buyer schemes, detail stamp duty reliefs, and provide step-by-step guidance on securing your first mortgage.

Minimum Deposit Requirements for First-Time Buyers

The deposit is your cash contribution to the purchase price. Lenders measure this using the **Loan-to-Value (LTV) ratio**, which represents the mortgage size as a percentage of the property’s purchase price. For first-time buyers:

• 5% Deposit (95% LTV): The minimum deposit required by most UK lenders. This means for a £200,000 property, you must save £10,000 in cash. While it makes getting on the ladder easier, interest rates on 95% LTV deals are generally higher.
• 10% to 15% Deposit (90% to 85% LTV): Securing a 10% or 15% deposit unlocks significantly lower interest rates, reducing your monthly payments.

First-Time Buyer Support Schemes

Several specialized schemes exist to help first-time buyers boost their purchasing power:

• Lifetime ISA (LISA): A tax-free savings account where the government adds a 25% bonus to your savings (up to £1,000 bonus per year on a maximum £4,000 saving). The funds must be used to purchase your first home valued up to £450,000.
• Shared Ownership: Allows you to buy a share of a property (typically between 10% and 75%) from a housing association and pay rent on the remaining share. This reduces the deposit size required.
• Guarantor / Springboard Mortgages: Allows family members to assist by placing cash in a savings account held by the lender as security, or using their own property as backup, enabling you to secure a 100% LTV mortgage (no deposit).

Step-by-Step Buying Process

Securing a home requires navigating a series of financial and legal stages. Ensure you follow these steps:

1. Get an Agreement in Principle (AIP): A document from a lender indicating how much they are likely to lend you based on a soft credit check. This proves to sellers you are a serious buyer.
2. Instruct a Solicitor: Hire a conveyancing solicitor to handle the legal search and title transfer work.
3. Submit a Full Mortgage Application: Once your offer on a property is accepted, submit your application with payslips, bank statements, and tax documents.
4. Exchange of Contracts & Completion: Once the mortgage is formally approved, legal contracts are exchanged, the deposit is paid, and finally, funds are transferred to complete the purchase.
