First-Time Buyer in 2026: A Realistic Step-by-Step Guide

Buying your first home involves more moving parts than most people expect going in. Here’s a realistic, current step-by-step walkthrough - including the genuine figures first-time buyers are facing in 2026.

The current picture

• Average first-time buyer age: around 33.9 years, up considerably over the past decade.
• Average first-time buyer house price: around £226,000 nationally (January 2026), rising to roughly £472,000 in London specifically.
• Average first-time buyer deposit: estimates range from around £54,000 to £63,000 depending on the survey and year - typically around 20% of the purchase price nationally.

Step 1: work out a realistic budget

Before house-hunting, get a clear picture of what you can actually afford - not just the maximum a lender might offer, but what’s comfortable given your other costs (see our dedicated article on mortgage affordability rules, which covers why lenders often offer less than you might expect, and why that’s not necessarily a bad thing).

Step 2: build your deposit, using every available scheme

A Lifetime ISA is the single most valuable tool for most first-time buyers under 40, offering a 25% government bonus on savings up to £4,000 a year (see our dedicated LISA article, including a major reform currently in consultation). Also check whether the Mortgage Guarantee Scheme - made permanent in July 2025, supporting 91–95% loan-to-value mortgages on properties up to £600,000 - could reduce the deposit you need if saving the traditional 10-20% isn’t realistic on your timeline (see our dedicated article on 95% mortgages).

Step 3: get a mortgage agreement in principle

An agreement in principle (AIP) gives you an estimate of how much you could borrow, based on a soft credit check, before you start making offers on properties - most estate agents expect to see one before taking an offer seriously.

Step 4: budget for stamp duty and other upfront costs

First-time buyers pay no Stamp Duty Land Tax on the first £300,000 of a purchase, and 5% on the portion from £300,001 to £500,000 - with no relief at all if the price exceeds £500,000 (see our dedicated stamp duty article for the full detail and worked examples). Beyond stamp duty, budget for a survey, conveyancing fees, and mortgage arrangement or broker fees, none of which are usually covered by the deposit itself.

Step 5: find a property and make an offer

Once you have an AIP, you can make offers with confidence about your realistic budget. A survey (beyond the lender’s own valuation) is strongly worth commissioning separately, since the lender’s valuation exists to protect their lending decision, not to flag issues that matter to you as the buyer.

Step 6: apply for the full mortgage

This involves a full affordability assessment, including a hard credit check and detailed review of your income and outgoings (see our mortgage affordability article). You’ll also need to settle on the mortgage product itself - most first-time buyers lean toward a fixed rate for the payment certainty, though it’s worth weighing how a fixed compares with a tracker in the current rate environment before committing. Self-employed buyers face some additional documentation requirements - see our dedicated article on this.

Step 7: conveyancing and completion

Your solicitor or conveyancer handles the legal transfer of the property, including searches, contract exchange, and eventually completion - typically taking 8–12 weeks from offer acceptance, though this varies considerably by chain length and circumstances.

The bottom line

Buying a first home in 2026 means navigating higher average deposits and prices than a decade ago, but also more support tools than ever - the Lifetime ISA and the now-permanent Mortgage Guarantee Scheme both meaningfully reduce the deposit barrier for buyers who use them deliberately, rather than assuming a traditional 10-20% deposit is the only route in.
