How much you can borrow, what deposit you need, which mortgage to choose, and how the application process works — everything first-time buyers need to know about getting a mortgage in 2026.

Getting a mortgage as a first-time buyer in 2026 is more straightforward than it was at the 2023 rate peak — rates have eased meaningfully and lender appetite for first-time buyer business is strong. But the process still has moving parts that catch people out: income multiples, stress tests, the difference between an Agreement in Principle and a formal offer, and why the mortgage you are quoted today may not be the one you complete on in four months. Understanding the mechanics before you apply puts you in a significantly stronger position.

How much can you borrow?

Most UK lenders use an income multiple as the primary borrowing cap — typically 4× to 4.5× your annual gross income (or combined gross income for joint applications). Some lenders offer up to 5.5× income for buyers with larger deposits, strong employment records, and higher incomes. The income multiple is a ceiling, not a starting point — your actual borrowing capacity is whichever is lower: the income multiple, or what passes the lender's affordability stress test.

Mortgage term — how long should you borrow for?

TermMonthly payment on £220,000Total interest paidVerdict
20 years~£1,370/mo~£109,000Lowest total cost — requires higher monthly payment
25 years~£1,185/mo~£135,000Traditional standard — good balance of payment and total cost
30 years~£1,065/mo~£163,000Popular in 2026 — lower payments, more flexibility
35 years~£980/mo~£192,000Maximum affordability — significantly higher total interest

Longer mortgage terms have grown more common among first-time buyers as affordability has been stretched. A 30-year term instead of 25 years reduces monthly payments meaningfully — on a £220,000 mortgage at 4.2%, that is around £120/month. The trade-off is paying approximately £28,000 more in interest over the full term. Most buyers who choose a longer term make overpayments when finances allow, effectively shortening the term without the commitment. Use our mortgage overpayment calculator to model the impact.

The mortgage application process — step by step

1
Check your credit file and fix any errors

Before applying for anything, check your credit report on all three agencies (Experian, Equifax, TransUnion — available free via Clearscore, Experian app, or Credit Karma). Errors are common and can cost you a better rate or result in declined applications. Allow 4–8 weeks to resolve any issues.

2
Instruct a whole-of-market mortgage broker

A whole-of-market broker accesses every lender, knows which are most likely to approve your specific circumstances, and submits applications efficiently. Most charge no direct fee — they receive a commission from the lender. Use a broker before going direct to any lender. See the section below on broker vs direct.

3
Get an Agreement in Principle (AIP)

Your broker runs a soft credit search and confirms the lender's indicative willingness to lend. An AIP is not a guarantee — it is an indication. Take it to property viewings and include it with offers to demonstrate credibility. See our AIP guide for exactly what it means and does not mean.

4
Full application after offer accepted

Once an offer is accepted, your broker submits the full mortgage application. You will need: last 3 months' payslips, 3 months' bank statements, P60 (last tax year), proof of deposit source, your ID, and the property details. Self-employed applicants need 2–3 years of SA302s or accountant's certificates.

5
Lender valuation of the property

The lender instructs a surveyor to confirm the property is worth the purchase price. If the surveyor values it lower (a "down-valuation"), the lender will only offer a mortgage based on the lower figure — meaning you must either renegotiate the price, increase your deposit, or find a different lender. This happens on roughly 5–10% of purchases.

6
Formal mortgage offer issued

If the application and valuation are satisfactory, the lender issues a formal mortgage offer — typically valid for 6 months. Your solicitor receives a copy and reviews the conditions. The offer may include conditions that must be satisfied before funds are released (for example, specific repairs or a retention held back pending reinspection).

7
Drawdown on completion day

On completion day, your solicitor requests the funds from the lender. The mortgage amount is transferred to the seller's solicitor along with your deposit. Ownership transfers and you collect your keys. See our conveyancing guide for exactly what happens on completion day.

Mortgage broker vs going direct — which is better?

Whole-of-market broker
Recommended for most first-time buyers
Accesses every lender — finds the best rate for your specific profile
Knows which lenders are flexible on income multiples, deposit size, or employment type
Handles the application, chases the lender, and manages issues
Fee-free options available — paid by lender on completion
Particularly valuable for non-standard income (self-employed, contract workers, multiple jobs)
Going direct to a lender
Appropriate in limited circumstances
Some lenders offer exclusive rates only available direct (not always cheaper overall)
Faster if you already know exactly which lender and product you want
No broker intermediary — you handle all communication yourself
You will not know if a better deal exists with another lender
Less support if the application hits complications

The five most common first-time buyer mortgage mistakes

Applying to multiple lenders simultaneously — each hard credit search leaves a mark on your file. Use one broker, one application.
Accepting the estate agent's in-house mortgage broker recommendation without comparing alternatives. Estate agents earn referral fees; their in-house broker may not find you the best rate.
Not checking your credit file before applying. An error from five years ago or an old missed payment can cost you a preferred rate.
Changing jobs or taking out new credit between AIP and formal application. Both can change your affordability assessment or invalidate the AIP entirely.
Not accounting for the mortgage arrangement fee in the total cost comparison. A mortgage with a £1,999 fee at 4.0% may cost more over the fixed period than a fee-free product at 4.2% — calculate the true total cost.

Frequently asked questions

Can I get a mortgage with a 5% deposit in 2026?

Yes — 95% LTV mortgages (5% deposit) are available from several high-street lenders. The rates are significantly higher than at 10% or 15% LTV — currently around 5.3–5.9% for a 5-year fix versus 4.1–4.5% at 85% LTV. On a £220,000 mortgage, this rate differential costs approximately £180–230/month. The Mortgage Guarantee Scheme (which allows lenders to offer 95% LTV with a government guarantee) has helped maintain lender appetite for this market. If you can wait and save to 10%, the monthly saving is meaningful — but 5% is a viable route if you need to act now.

How long does a first-time buyer mortgage take to be approved?

From full application to formal mortgage offer typically takes 2–4 weeks with most mainstream lenders in 2026, though this varies. Online lenders and those with automated underwriting can move faster (7–14 days). Complex applications (self-employed income, unusual property types, very large loans) may take 4–8 weeks. The lender's valuation is usually the longest single step — particularly in busy markets where surveyors are stretched. Your broker will advise on expected timelines for your specific lender of choice. See our mortgage approval timeline guide for more detail.

Should I choose a 2-year or 5-year fixed rate as a first-time buyer?

In 2026, the rate difference between 2-year and 5-year fixes is typically 0.1–0.4%. For most first-time buyers, a 5-year fix is the stronger default choice — it provides payment certainty for five years, eliminates the cost and admin of remortgaging in 2028, and protects against any upward rate movement. A 2-year fix makes sense if you have a specific reason to want flexibility in two years — planning to move, expecting a significant income increase, or strongly expecting further rate falls. For most buyers, the certainty of five years at a known rate outweighs the modest rate premium. See our fixed vs tracker guide for the full comparison.

Important: Mortgage rates and lender criteria change frequently. All figures are indicative for early 2026. Income multiples, affordability stress tests, and product availability vary between lenders. Consult a qualified, independent whole-of-market mortgage broker before making any mortgage decision.
