One of the very first and most important questions anyone thinking about buying a home in the UK asks is usually along the lines of: “Am I Eligible for a Mortgage?”
It’s a question that’s both exciting and a little terrifying because understanding what lenders are looking for is the key that unlocks the door to homeownership.
The good news is eligibility isn’t some hidden secret; it’s based on a range of understandable factors. To that end, today, we’re breaking down some of the main criteria UK lenders typically assess when they determine mortgage eligibility here in the UK.
We’ll be exploring how these various factors interact and, importantly, how you can get a clearer picture of your own situation.

Understanding the basics of mortgage eligibility
Sadly, getting a mortgage isn’t as simple as just wanting one. These are significant sums of money we’re talking about and lenders need to be confident that you can afford the repayments reliably throughout the loan term.
This means they conduct a thorough assessment known as an affordability check.
Within these checks, there’s no single magic number or formula that guarantees eligibility. Instead lenders look at a combination of factors to build a complete picture of your financial health and risk profile.
The good news is that by understanding something about the most common criteria you’ll be better placed to confidently answer the question “Am I Eligible for a Mortgage?” for yourself.
With a variable rate your monthly payments can fluctuate, making budgeting less predictable but potentially delivering savings should rates fall.
Six key factors that impact mortgage eligibility
All lenders are going to carefully look at several areas of your finances before deciding if lending to you is a responsible decision. As a result, when you’re wondering “Am I Eligible for a Mortgage?” these are some of the aspects you’ll need to consider:
1. Your income and employment status
In nearly all cases, your income is a primary factor. Lenders want to see a stable and sufficient income to cover mortgage payments and other living costs. Mortgage lenders will look at
- your gross annual salary
- the nature of your employment.
If you’re PAYE
Those in permanent PAYE (Pay As You Earn) roles often find this part straightforward.
If you’re self-employed
If you’re self employed, a contractor or rely heavily on bonuses and commission, lenders will typically want to see a longer track record (usually two to three years of accounts or tax returns to verify income consistency).
While lenders often use an income multiple (maybe around 4 to 4.5 times your annual income) as an initial rough guide, this is by no means a guarantee and varies widely. The stability and provability of your income are usually most important.
2. The size of your deposit (or the Loan-to-Value)
The amount of deposit you can put down directly impacts your Loan-to-Value (LTV) ratio: essentially the size of the mortgage compared to the property’s value.
A larger deposit means a lower LTV and this translates to lower risk for the lender. Generally a lower LTV can improve your eligibility and give you access to more competitive interest rates.
While some mortgages are available with as little as a 5% deposit (95% LTV) providing 10% 15% or more will significantly strengthen your application and broaden your options.
3. Your credit history and score
Your credit history is a detailed record of how you’ve managed borrowing in the past. Lenders use this along with your credit score (a numerical representation of your history) to assess your reliability as a borrower.
A strong credit history showing consistent on-time payments for any existing credit (like credit cards loans or even mobile phone contracts) and no defaults or County Court Judgements is highly favourable. A poor credit history can severely limit your options or lead to higher interest rates, making a positive answer to “Am I Eligible for a Mortgage?” more challenging.
It’s always a good idea to check your credit report with the three main UK agencies (Experian, Equifax and TransUnion) before applying for a mortgage to identify and correct any errors.
4. Existing debts and regular outgoings
Lenders don’t just look at your income; they assess your affordability by carefully examining your existing financial commitments. This includes things like:
- Outstanding balances on credit cards and store cards
- Personal loans
- Car finance agreements
- Student loans
- Hire purchase agreements
They also consider your regular committed outgoings such as childcare costs, school fees, travel or commuting expenses, insurance payments and even estimates for council tax and utility bills.
The lower your existing debt and fixed outgoings are relative to your income the more favourably your affordability will be viewed.
5. Your age and mortgage term
Your age can influence the maximum mortgage term a lender is willing to offer. Most lenders want the mortgage to be fully repaid by your anticipated retirement age (often assumed to be between 65 and 70 though some are more flexible). A longer mortgage term will result in lower monthly payments but you’ll pay more interest overall. A shorter term means higher monthly payments but less total interest paid.
6. Property type and value
Occasionally the property itself can affect eligibility for certain mortgage products. For instance, lenders may have stricter criteria or require larger deposits for non-standard construction properties (e.g. timber-framed, some types of concrete construction) or flats above commercial premises. A property valuation will always be required to confirm its suitability as security for the loan.
How to get a clearer idea of your mortgage eligibility
While understanding these factors is helpful, getting a personalised assessment is almost always the best way forward.

Find out how much you could borrow
Get a mortgage in principle
A Mortgage in Principle (also known as an Agreement in Principle) is a more formal indication from a specific lender of how much they might be willing to lend you. It involves providing more detailed personal and financial information and often includes a ‘soft’ credit check which doesn’t impact your credit score. A MIP gives you more confidence when viewing properties and shows estate agents you’re a serious buyer. This is a very strong indicator of whether your answer to “Am I Eligible for a Mortgage?” is likely to be positive with a particular lender.
