How much deposit do I need as a first-time buyer in 2026?

Minimum 5% of property price, ideally 10-15% for best mortgage rates. On a £250,000 property, 5% = £12,500 deposit (95% LTV mortgage), 10% = £25,000 (90% LTV), 15% = £37,500 (85% LTV). Each 5% LTV step typically reduces interest rate by 0.2-0.4%. On a 25-year mortgage, dropping from 95% to 85% LTV saves approximately £12,000-£20,000 in interest over the term.

What is the Lifetime ISA (LISA) and should I open one?

LISA allows you to save up to £4,000/year (counting toward £20,000 ISA limit) with a 25% Government bonus. Use for first home (up to £450,000) or retirement at 60. £4,000 + £1,000 bonus = £5,000/year. Over 5 years that's £25,000 of bonus on £20,000 of savings. Strong recommendation for any first-time buyer aged 18-39 - open one as soon as eligible.

How much can I borrow as a first-time buyer?

Standard UK lender rule: 4 to 4.5× annual gross income for sole applicants, or combined income for joint applicants. Stretched lenders offer 5× or even 5.5× for high earners (typically £60k+). On £50k salary: 4× = £200,000 mortgage; 4.5× = £225,000; 5× = £250,000. Add deposit to get maximum property price you can buy. Use our mortgage affordability calculator to model your specific case.

What is SDLT first-time buyer relief in 2026?

First-time buyers in England + NI pay no Stamp Duty on the first £300,000 of property price, and 5% on the slice £300,000-£500,000. Above £500,000 the relief is lost entirely - standard SDLT rates apply to the full property value. Available only if the property is your main residence, you've never owned a property before (worldwide), and the property is ≤£500,000.

What are typical completion costs beyond the deposit?

4-7% of property price in total additional costs. For a £250,000 property: SDLT (£0 for FTB) + survey (£400-£1,500) + conveyancing solicitor (£800-£2,000) + mortgage arrangement fee (£500-£2,000) + valuation (£0-£300) + searches (£250-£400) + buildings insurance (~£200/year) + removals (£300-£1,500) = £2,250-£7,900 typical. Add SDLT for non-first-time buyers.

How long does the buying process take in 2026?

Average 12-16 weeks from offer accepted to completion (keys handed over) in 2026. Stages: offer accepted (week 1), mortgage application (weeks 1-4), property survey (weeks 2-4), legal searches + conveyancing (weeks 4-12), exchange contracts (week 12-14), completion (week 14-16). Chain length is the biggest variable - if your seller is also buying (typical chain), add 2-4 weeks. Chain-free purchases (new builds, FTB-to-vacant) complete fastest.

Should I get a fixed-rate or tracker mortgage in 2026?

Depends on rate outlook + personal stress tolerance. June 2026 typical 5-year fix: ~4.25-4.75%. 2-year fix: ~4.5-5.0%. Tracker (Base Rate + margin): ~4.5-5.5% depending on Base Rate. Most first-time buyers choose 5-year fix for payment certainty + protection if rates rise. Trackers benefit only if Base Rate falls more than mortgage holders forecast - currently a minority view.

What is the stress test for UK mortgage affordability?

Lenders must assess whether you could still afford the mortgage if rates rose (FCA/PRA formal 3pp stress test was withdrawn August 2022; lenders now use reversion-rate +~1pp under MCOB rules). So on a 5% fixed-rate, lender stress tests at ~8%. Income evidence required: 3 months of payslips + bank statements + (if self-employed) 2 years of accounts or SA302. Stress test failure is the most common reason for mortgage application rejection.

Can I use the Help to Buy ISA for my deposit?

Only if you opened one before 30 November 2019 (the scheme closed to new applicants). Existing Help to Buy ISA holders can continue contributing until November 2029 and claim bonus until December 2030. £200/month max contribution + 25% Government bonus on completion. Maximum bonus £3,000 on £12,000 saved. Strong scheme but closed to new entrants - new FTBs use LISA instead.

What's the realistic timeline to save a UK first-time buyer deposit?

For a £25,000 deposit (10% of £250k property) on a £45,000 salary: net income ~£35,000, after rent + bills ~£18,000 disposable. Saving £750/month + LISA 25% bonus = £11,250/year. ~2-3 years to £25k. For higher property prices or lower incomes, the timeline extends to 4-7 years. Most realistic UK FTBs save for 3-6 years before purchase.

UK First-Time Buyer Complete Guide 2026/27

Comprehensive guide to buying your first home in the UK 2026 - deposit savings strategy (LISA + cash ISA), SDLT first-time buyer relief, mortgage affordability rules, stress tests, completion costs, and realistic timeline.

The 8-step UK first-time buyer process

Save deposit (3-6 years typical) - 5% minimum, 10-15% for best mortgage rates
Get mortgage agreement in principle (1 week) - shows estate agents you're serious
House hunt + viewings (2-12 weeks)
Make offer + agree (1-2 weeks negotiation)
Mortgage application + survey (3-6 weeks)
Conveyancing + searches (8-12 weeks)
Exchange contracts (deposit becomes non-refundable)
Completion (2-4 weeks after exchange) - keys handed over

Deposit savings strategies

Lifetime ISA (LISA) - first stop

Best deposit-saving vehicle for anyone aged 18-39 buying a first home up to £450,000. Mechanics:

Open at any bank or building society between ages 18-39
Save up to £4,000/year (counts toward £20,000 ISA limit)
Government adds 25% bonus monthly (£1,000/year max)
Use for first home OR retirement at 60+
Withdrawal for any other reason = 25% penalty (~6.25% net loss vs contribution)

Over 5 years of £4,000/year contributions:

Total contributions: £20,000
Government bonus: £5,000
Plus interest (~3-4% on cash LISA): ~£2,000-£3,000
Total: ~£27,000-£28,000

Cash ISA - tax-free interest

Standard cash ISA for any amounts above £4,000/year (LISA limit). 2026/27 ISA allowance £20,000 total per individual. Best cash ISA rates currently 4.5-5.0% on easy-access.

Stocks & Shares ISA - longer-term horizon

For deposit savings 5+ years away. Higher expected return (long-run UK + global equities ~7% nominal) but volatility. Not recommended if you might buy within 2-3 years - market timing risk.

Workplace pension + Salary Sacrifice

Indirect deposit strategy: maximise pension contributions to reduce taxable income + grow tax-free, then use other savings for deposit. Reduces overall tax burden across saving + housing.

SDLT (Stamp Duty) for first-time buyers

England + NI 2026 SDLT rates for first-time buyers (purchases up to £500,000):

Property price band	FTB rate	Standard rate (non-FTB)
£0 - £300,000	0%	0% up to £125k; 2% £125k-£250k
£300,000 - £500,000	5%	5%
£500,000+	No FTB relief - standard rates apply	5% £250k-£925k; 10% £925k-£1.5m; 12% £1.5m+

Worked example: FTB buying £250,000 property = £0 SDLT (vs £2,500 for non-FTB). £400,000 property FTB = £5,000 SDLT. £550,000 FTB loses all relief - pays standard SDLT £17,500 (£0 on first £125k + £2,500 on £125k-£250k at 2% + £15,000 on £250k-£550k at 5%).

Scotland uses LBTT (Land and Buildings Transaction Tax) with different bands - see LBTT calculator. Wales uses LTT (Land Transaction Tax) - see LTT calculator.

Mortgage affordability + stress test

How much you can borrow

Standard UK lender approach:

Income multiple: 4-4.5× gross income (5-5.5× for high earners)
Affordability: monthly mortgage payment + bills should leave reasonable disposable income
Stress test: can you still afford payments if rates rose by 3 percentage points?
Loan to Value (LTV): max typically 95%, best rates at 60% LTV

Worked example: £50k salary

Multiple	Max mortgage	With 10% deposit
4× (conservative)	£200,000	£222,222 max property
4.5× (standard)	£225,000	£250,000 max property
5× (stretched)	£250,000	£277,777 max property

Total cost of buying: beyond the deposit

Realistic additional costs on a £250,000 property purchase:

Cost	Typical range	When paid
Deposit (10%)	£25,000	At exchange / completion
SDLT (FTB on £250k)	£0	At completion
Conveyancing solicitor	£800-£2,000	£500 upfront, balance at completion
Mortgage valuation	£0-£300	Mortgage application
Homebuyer survey	£400-£700	After offer accepted
Full structural survey (older properties)	£600-£1,500	After offer accepted
Mortgage arrangement fee	£500-£2,000	Added to loan or paid upfront
Local authority searches	£250-£400	Conveyancing stage
Buildings insurance	£200-£500/year	From exchange
Removals + immediate furniture	£500-£3,000	Around completion

Plan for £3,500-£8,500 of additional costs beyond deposit. For non-FTB or higher property prices, add SDLT.

Common first-time buyer mistakes

Stretching to maximum borrowing. Leaves no margin for rate rises or life changes. Borrow 80% of maximum, not 100%.
Ignoring service charges + ground rent on leasehold flats. Can add £200-£500/month on top of mortgage.
Not getting full structural survey on Victorian or older properties. Repairs can cost £20k+.
Choosing 2-year fix to minimise rate. Two years of payment uncertainty plus remortgage costs every 2 years.
Insufficient deposit cushion. Spend literally all savings on deposit + costs, then no buffer for boiler / roof / unexpected costs.
Buying in chain when chain-free option exists. Chain collapses are the #1 reason FTB transactions fall through.
