First-Time Buyer Mortgages in 2025: How to Secure the Best Deal and Maximise Your Borrowing Power

12 August 2025

Your complete guide to navigating the UK mortgage market as a first-time buyer in 2025. From lender expectations to financial preparation

Stepping onto the property ladder in 2025 is exciting, but it can also feel overwhelming. Rising property prices, evolving lending rules, and competitive markets mean first-time buyers need to prepare more thoroughly than ever before. The good news? With the right approach, you can increase your borrowing potential, improve your chances of approval, and lock in a mortgage deal that works for you both now and in the long term.


This guide walks you through what lenders are really looking for, the steps you should take before you apply, and how working with the right broker can give you an advantage.


Understanding Lender Affordability Checks


Lenders don’t just base their decision on your salary. They will look closely at your income type and stability, any existing debts, your credit score, and even your spending patterns. If your income includes bonuses, commission, or self-employment, it’s important to present this in a way lenders recognise as sustainable. Our guide on getting a mortgage with complex income explores how to approach this effectively.


A clean credit history and a sensible level of monthly outgoings can make a significant difference to how much you can borrow. If your credit file needs improvement, our article on overcoming poor credit outlines the practical steps to take.


Strengthening Your Position Before You Apply


In the year before you apply, aim to make yourself the kind of borrower lenders want to work with. That means paying all bills on time, avoiding unnecessary credit applications, and reducing any outstanding debts. Clearing or reducing loans and credit cards can have a direct impact on your affordability calculation. For some buyers, consolidating debt may be the right move — you can read more in our guide on debt consolidation with property finance.


It’s also worth increasing your deposit wherever possible. A larger deposit will lower your loan-to-value (LTV) ratio, which not only makes you less risky to lenders but may also open up access to more competitive rates.


Exploring Schemes and Specialist Products


First-time buyers in 2025 may have access to schemes such as Shared Ownership or the First Homes initiative, depending on eligibility. In addition, specialist lenders offer products tailored to those with non-standard income, limited credit history, or smaller deposits. A broker with whole-of-market access can identify these opportunities and help you secure a mortgage you might not find on your own.


Why Broker Choice Matters


Not all brokers are the same. The right broker can anticipate challenges before they arise, package your application in the most favourable light, and access deals you won’t see on the high street. Our article on what makes a good mortgage broker in 2025 explains what to look for if you want the best possible chance of approval.
