What Mortgage Lenders Look For

Income and Affordability

Your income is the foundation of any mortgage application. Lenders need confidence that you can afford the payments—not just now, but if circumstances change.

Income Multiples

Most lenders offer mortgages of 4-4.5 times your annual income. Some stretch to 5-5.5 times for specific applicants (high earners, certain professions). If you earn £50,000, expect to borrow £200,000-225,000 typically.

This varies by lender. Some are more generous; others more conservative. A broker can identify who offers what for your situation. Check our affordability calculator to estimate your borrowing capacity.

Affordability Stress Testing

Beyond income multiples, per FCA MCOB rules, lenders run affordability calculations. They don't just check if you can afford payments at current rates—they test whether you could manage if rates rose by 2-3%.

This stress testing is required by regulation. It's why two people earning the same amount might be offered different borrowing limits—their outgoings affect affordability differently.

Types of Income Counted

Lenders treat income sources differently:

If your income has complexity, a broker helps present it most favourably.

Outgoings Assessment

Lenders look at your committed expenditure:

• Existing debt payments (loans, credit cards, car finance)
• Childcare costs
• Maintenance payments
• Other mortgages
• Regular commitments

High outgoings reduce what you can borrow, even with good income.

Credit History

Your credit history tells lenders how you've managed financial commitments in the past. It's not about being perfect—it's about demonstrating reliability.

What They Check

Lenders see:

• Payment history on credit accounts (cards, loans, mortgages)
• Any defaults or late payments
• County Court Judgments (CCJs)
• Bankruptcies or IVAs
• Current debt levels
• Credit applications

How Far Back They Look

Different issues have different relevance periods:

Recent issues matter more than historical ones. A missed payment 5 years ago is far less concerning than one 5 months ago.

What Counts Against You

Serious issues that concern lenders:

• Multiple recent missed payments
• Defaults (especially recent or multiple)
• CCJs (particularly unsatisfied)
• High credit utilisation (using most of available credit)
• Frequent payday loan usage
• County court action

What Doesn't Matter

Some things worry people unnecessarily:

• Having no debt (though some credit history helps)
• Checking your own credit score
• Shopping around for quotes (soft searches)
• Old, small issues (single missed phone bill years ago)
• Being rejected by other lenders (this isn't shared)

Improving Your Credit

If your credit needs work:

• Register on the electoral roll
• Pay all bills on time, every time
• Reduce credit utilisation below 30%
• Fix any errors on your report
• Avoid new credit applications before mortgage

Employment and Stability

Lenders want to see stable, reliable income. How they assess this depends on your employment type.

Employment Types

Time in Job

Most lenders prefer at least 3-6 months with your current employer. Recent job changes aren't automatic blockers, especially if:

• You're in the same industry
• Your income has increased
• You have strong overall employment history

Self-Employed Requirements

Per FCA guidance for self-employed, self-employed applicants face additional scrutiny:

• 2-3 years of trading history usually required
• SA302 forms and tax year overviews needed
• Accountant-prepared accounts preferred
• Income calculated from accounts (not turnover)

Contract Workers

Per IMLA contractor guidance, contractors can get mortgages, but approach matters:

• Some lenders use day rate x 5 days x 46-48 weeks
• Others want to see employed income over time
• Track record of contract renewals helps
• A broker familiar with contractors is essential

Probation Periods

Being on probation doesn't automatically prevent mortgages, but it limits options. Some lenders accept applications during probation; others require you to pass first. A broker identifies appropriate lenders.

Deposit and LTV

Your deposit determines your loan-to-value (LTV) ratio—the percentage of the property's value you're borrowing. This affects both approval chances and available rates.

Minimum Deposits

The absolute minimum is typically 5% of the purchase price. However:

• 5% deposits limit lender options
• Rates are significantly higher at 95% LTV
• Approval is harder at maximum LTV

How Deposit Affects Approval

Larger deposits help in multiple ways:

LTV Bands Explained

Lenders price mortgages in LTV bands. Moving from 91% to 89% LTV might save 0.2-0.3% on your rate. LTV matters more than most buyers realise. Use our deposit calculator to understand deposit requirements.

Gifted Deposits

Family gifts are acceptable, but lenders require:

• Gift letter stating it's not a loan
• Confirmation no repayment is expected
• Donor ID in some cases
• Evidence of donor's source of funds (for large gifts)

Per FCA lending requirements, "gifts" that are actually loans create problems. Lenders specifically ask, and undeclared loans are mortgage fraud.

Property Factors

The property itself affects approval. Lenders care because it's their security—if you default, they need to sell it.

Property Types Accepted

Most standard properties are fine. Concerns arise with:

• Non-standard construction (concrete, steel frame, etc.)
• High-rise flats (above certain floors)
• Ex-local authority (some lenders)
• Very small properties (under 30 sqm)
• Commercial elements
• Uninhabitable condition

Construction Type Issues

Non-standard construction doesn't prevent mortgages, but limits options:

Lease Length (Flats)

Per FCA lending requirements, for leasehold properties, remaining lease length matters critically:

Location Factors

Some locations create difficulties:

• Flood risk areas
• Subsidence zones
• Near commercial premises
• Above shops (some lenders)
• Certain postcodes (rare, but exists)

Valuation Requirements

Per HM Land Registry guidance, the lender values the property to confirm:

• It exists and matches description
• It's worth at least the purchase price
• There are no obvious issues
• It's suitable security for the loan

Down-valuations (property valued below purchase price) affect about 10% of purchases.

Red Flags for Lenders

Certain patterns concern lenders more than individual issues.

Recent Credit Issues

Problems in the last 12 months are particularly concerning:

• Missed payments
• New defaults
• High utilisation
• Multiple credit applications

Gambling Transactions

Regular gambling appears in bank statements. Lenders increasingly flag this:

• Frequent betting app transactions
• Casino/poker site deposits
• Even small regular amounts raise questions

This doesn't automatically prevent approval, but may require explanation.

Payday Loans

Payday loan usage—even if fully repaid—signals financial stress to lenders. Recent usage is particularly problematic. Some lenders decline anyone with payday loans in the last 12-24 months.

Undisclosed Debts

Debts that appear on credit searches but weren't declared in your application cause immediate concern. Lenders wonder what else you haven't mentioned. Always disclose everything.

Green Flags for Lenders

These factors make approval more likely.

Stable Employment

Long tenure with one employer, in a permanent role, with consistent income—this is the ideal lenders look for. Doesn't mean you need it, but it helps.

Clean Credit

No missed payments, defaults, or judgments. Credit accounts used responsibly. Balances paid regularly. This demonstrates reliable financial behaviour.

Large Deposit

Bigger deposits reduce lender risk. If you can put down 25%+ and demonstrate saving capacity, you're an attractive borrower.

Low Debt-to-Income

If your existing debts are low relative to income, you have more capacity for mortgage payments. Paying down debt before applying improves this ratio.

Evidence of Saving

Regular saving—shown by deposit accumulation—demonstrates financial discipline. Lenders like seeing consistent saving patterns in bank statements.

Improving Your Position

If you're concerned about approval, here's what to do before applying.

Before You Apply

3-6 months before:

• Check your credit report (all three agencies)
• Fix any errors
• Stop new credit applications
• Reduce credit card balances
• Ensure you're on electoral roll

1 month before:

• Gather all documents
• Review bank statements for anything concerning
• Calculate your debt-to-income ratio
• Get mortgage in principle

Credit Quick Wins

Some improvements happen quickly:

• Reduce credit utilisation (days/weeks)
• Register on electoral roll (days)
• Fix errors on credit file (weeks)
• Add financial association correctly (days)

Other improvements take time:

• Building credit history (months/years)
• Waiting for old issues to age (years)
• Improving income stability (months/years)

Documentation Preparation

Having everything ready speeds approval:

• 3 months payslips
• Latest P60
• 3-6 months bank statements
• ID documents
• Deposit evidence
• Employment details

How long does bad credit affect mortgage approval?

It depends on the severity. Minor issues (single missed payment) matter less after 2-3 years. Defaults and CCJs remain on your file for 6 years. Bankruptcy requires 6 years from discharge at minimum. The impact diminishes over time, and different lenders have different policies.

Will my overdraft usage affect my mortgage application?

Arranged overdrafts used occasionally aren't usually problematic. However, being constantly at your overdraft limit, or frequently going into unarranged overdraft, concerns lenders. It suggests income doesn't cover expenses.

Does checking my credit score hurt my chances?

No. Checking your own credit score is a "soft search" that only you can see. Lenders see it on your file but it doesn't affect their assessment. Check often—it helps you spot issues before applying.

Can I get a mortgage with a CCJ?

Yes, but options are limited. Some lenders accept satisfied CCJs after a certain period. Unsatisfied CCJs are harder. Specialist lenders and brokers can help identify options. Rates will be higher.

How much do lenders look at my spending?

Lenders review bank statements to verify income and assess spending patterns. They're looking for concerning patterns (gambling, payday loans) rather than judging individual purchases. The occasional takeaway won't affect your mortgage.

Next Steps

Understanding what lenders look for helps you prepare effectively. If anything concerning exists, address it before applying.
