First-Time Buyer Mortgage Guide 2026: Complete Step-by-Step Process for Home Ownership
The UK housing market in 2026 presents both opportunities and challenges for first-time buyers. Navigating the home-buying process requires careful planning and expert guidance.

What We'll Cover
Step 1: Financial Preparation
Understanding Deposit Requirements
Deposit requirements vary between lenders. While some lenders may accept deposits as low as 5%, many require 10% or more. Choosing the right deposit size impacts your mortgage rate and monthly payments.
Mortgage Guarantee Scheme (Freedom to Buy)
Introduced in July 2025, this permanent government scheme encourages lenders to offer 95% loan-to-value mortgages. The government provides guarantees to lenders, facilitating access for first-time buyers.
Lifetime ISA (LISA) Bonus
Available to buyers aged 18-39, the LISA offers a 25% government bonus on savings up to £4,000 annually, providing up to £1,000 extra per year for your deposit.
Step 2: Mortgage Affordability
Lenders assess affordability by analysing your income, expenditure, and conducting interest rate stress tests. This ensures you can sustain payments even if market conditions change. Credit commitments, childcare costs and student loan repayments all reduce the amount you can borrow.
Income Multiples
Success Factors
- Credit score and history
- Employment stability (6+ months)
- Debt-to-income ratio
- Monthly base expenditure
Stamp Duty and Other Costs (2026/27)
Your deposit is only part of the upfront bill. Solicitor fees, surveys, removals and Stamp Duty Land Tax (SDLT) in England and Northern Ireland can add thousands. Budget early so a last-minute SDLT bill does not derail completion.

Figures for the UK 2026/27 tax year: confirm on GOV.UK before acting.
Typical costs to plan for
- Conveyancing and searches, often £1,000–£2,000+ depending on property
- Survey, from a basic valuation to a full structural survey on older homes
- Mortgage fees, arrangement, booking or product fees (some can be added to the loan)
- Buildings insurance, required from exchange on most purchases
- Moving and furnishing, easy to underestimate in rural or coastal moves
Confirm SDLT before you exchange
Government Schemes Worth Knowing
Beyond saving a deposit, several UK schemes reduce the cash you need at completion. Eligibility, property type and lender participation vary, always check scheme rules alongside mortgage criteria.
Mortgage Guarantee Scheme (Freedom to Buy)
Supports 91–95% LTV mortgages with as little as 5% deposit through participating lenders. Not limited to first-time buyers, but widely used by them in 2026.
First Homes & Shared Ownership
First Homes offers discounted new-builds for eligible local buyers. Shared Ownership lets you buy a share (from 10%) and rent the rest, with staircasing over time. Stock in Somerset, Dorset and Devon depends on housing associations and developers, see our Help to Buy schemes guide.
Step 3: Choosing a Mortgage
Fixed Rate Mortgages
Payments remain constant for a set period (usually 2, 5, or 10 years). Ideal for budgeting and protection against interest rate rises.
Variable & Tracker Mortgages
Interest rates can fluctuate based on lender policies or the Bank of England base rate. Can offer lower initial rates but higher risk.
Step 4: The Application
Agreement in Principle
A non-binding indication from a lender showing how much you can borrow. Essential for proving your seriousness to sellers.
Formal Application
Submission of detailed financial records, including payslips, bank statements, and identification. This triggers full underwriting.
Underwriting & Valuation
Lender conducts a property valuation and detailed credit check before issuing a formal mortgage offer.

First-time buyer FAQs
How much deposit do I need in Somerset or Devon in 2026?
From 5% with some 95% LTV products, though 10% or more often unlocks better rates and a wider lender panel. Higher deposits matter more in expensive coastal markets such as parts of Dorset.
Does a Lifetime ISA still help with a deposit in 2026/27?
Yes, if you are aged 18–39 and meet the rules: save up to £4,000 per tax year into a LISA and receive up to a 25% government bonus (maximum £1,000 per year) for a qualifying first home purchase.
What is an Agreement in Principle and do I need one?
An AIP (or decision in principle) is a lender indication of how much you might borrow. It is not a guarantee, but estate agents and sellers in competitive areas often expect one before accepting an offer.
Can I get whole-of-market mortgage advice without visiting a branch?
Yes. Independent advice is available by phone and video from Yeovil across Somerset, Dorset and Devon, comparing products from a wide panel of lenders.
Will student loans stop me getting a mortgage?
Lenders assess affordability after plan repayments. A good credit history, stable income and manageable unsecured debt usually matter more than the loan balance alone.
Important information
Think carefully before securing debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage. Some buy-to-let mortgages are not regulated by the FCA.
