## First-Time Buyer Mortgages (UK)

## What is a first-time buyer mortgage?

A first-time buyer mortgage is a residential mortgage for someone who has never owned property anywhere in the world. The mortgage product itself is not fundamentally different from other residential mortgages; the distinction lies in eligibility, deposit requirements, affordability treatment, and available schemes.

First-time buyers are assessed under full FCA regulation and Consumer Duty, with enhanced scrutiny on affordability and sustainability.

## Who qualifies as a first-time buyer?

You are classed as a first-time buyer if:

- You have never owned a property before (UK or overseas)
- You are not named on a current or previous mortgage
- You are purchasing for owner-occupation

Joint applications qualify as first-time buyers only if all applicants meet the criteria.

## Deposit requirements

Most first-time buyer mortgages require:

- 5% minimum deposit (95% LTV products)
- 10-15% deposit for wider lender choice and better rates

Lower deposits increase:

- Interest rates
- Affordability sensitivity
- Risk of down-valuation

The source of deposit must be fully evidenced.

## Acceptable deposit sources

Lenders commonly accept deposits from:

- Personal savings
- Lifetime ISA (LISA)
- [Gifted deposits](https://mortgagelane.com/mortgages/gifted-deposit-mortgages) from close family
- Gifted equity ([concessionary purchases](https://mortgagelane.com/mortgages/concessionary-purchase-mortgages))
- Sale of assets (with evidence)

Borrowed deposits and unsecured loans are generally not acceptable.

## Affordability assessment

Affordability is the primary constraint for first-time buyers. Lenders assess:

- Gross income and sustainability
- Existing credit commitments
- Household expenditure
- Stressed interest rates
- Future cost assumptions (utilities, dependants, childcare)

Most lenders offer borrowing between 4.0-4.5× income, with higher multiples available in limited circumstances.

## Employment and income types accepted

First-time buyers can apply with:

- PAYE employment
- Self-employment
- Contract income
- Zero-hour or variable income

## Multiple income sources

Non-standard income is acceptable, but lender choice becomes more criteria-sensitive.

## Credit profile considerations

Credit history has a disproportionate impact on first-time buyers:

- Clean credit significantly expands lender choice
- Minor missed payments may still be acceptable
- [Defaults](https://mortgagelane.com/mortgages/mortgages-with-defaults), CCJs, or payday loan history reduce options

First-time buyers have no prior mortgage history, so personal credit behaviour carries more weight.

## Loan-to-value (LTV) limits

Typical outcomes include:

- Up to 95% LTV with strong affordability
- More competitive rates at 90% LTV or below
- Reduced options above 90% LTV for flats and new builds

LTV limits vary by property type and lender appetite.

## First-time buyer schemes

Some first-time buyers may benefit from:

- Lifetime ISA bonuses
- Shared Ownership
- Developer incentives (new builds)
- Local authority or regional schemes

Each scheme interacts differently with mortgage affordability and lender policy.

## Property types and restrictions

Lenders apply additional scrutiny to:

- New build flats
- High-rise developments
- Non-standard construction
- Leasehold properties with short leases

First-time buyers are more exposed to property-specific restrictions due to higher LTVs.

## Common reasons first-time buyer applications fail

Most issues arise from:

- Overestimating borrowing capacity
- Undeclared credit commitments
- Unacceptable deposit sources
- Down-valuations
- Applying to lenders misaligned with income type

These are criteria and preparation failures, not product issues.

## Mortgage term length and age limits

First-time buyers often take:

- 30-40 year mortgage terms to improve affordability
- Longer terms reduce monthly payments but increase total interest

Lenders assess whether the term remains affordable into later life.

## FCA regulation and consumer protection

First-time buyer mortgages are fully FCA-regulated. Lenders must:

- Evidence affordability under stress
- Ensure long-term sustainability
- Apply Consumer Duty to avoid foreseeable harm

This includes ensuring buyers are not stretched beyond realistic limits.

## Why specialist guidance matters

First-time buyer lending is affordability-led and criteria-sensitive. Successful outcomes depend on:

- Correct income assessment
- Lender selection aligned to deposit and property type
- Managing credit and affordability optics
- Anticipating valuation and scheme restrictions

Handled correctly, first-time buyers can access the most competitive mortgage products in the market.
