If you’re buying your first home and your income doesn’t come from a single PAYE salary, everything you read about getting a mortgage probably feels like it was written for someone else. The standard advice assumes a steady payslip, a clean deposit, and a straightforward application. Yours isn’t straightforward, and that’s fine, but it means the process works differently for you.
You might be self-employed, a company director, a contractor on a day rate, freelancing across multiple clients, or earning most of your income through commission or bonuses. You might also have credit history that isn’t perfect. None of these things prevent you from getting a mortgage. They change which lenders will say yes, how your income is assessed, and how the application needs to be put together.
This guide covers how lenders assess complex income for first-time buyers specifically, what counts as adverse credit and how it affects your options, what documents you’ll need, and the mistakes that get these applications declined.
What counts as “complex income” for a mortgage?
Complex income is any income that isn’t a single, straightforward PAYE salary paid monthly into one bank account. It’s a broad category, and lenders treat each type differently:
- Self-employed sole traders assessed on net profit from SA302 tax calculations
- Limited company directors assessed on salary plus dividends, or salary plus net/retained profit depending on the lender
- Contractors on fixed-term engagements, often assessed on day rate rather than accounts
- Freelancers earning from multiple clients with no single employer
- Commission or bonus earners where a significant portion of income is variable
- Multiple income streams such as employed plus self-employed, or salary plus rental income
The common thread is that lenders can’t just read a number off a payslip. They have to interpret, and different lenders interpret differently. Two lenders looking at exactly the same accounts can come back with completely different borrowing figures, not because your income changed, but because their assessment method did.
For a first-time buyer, this creates an extra challenge: you don’t have a track record of mortgage payments to fall back on. Lenders are assessing your income and your reliability at the same time, which is why how the application is presented matters even more.
How lenders assess each income type
This is where applications are won or lost, and it deserves more attention than most guides give it.
Self-employed (sole traders)
Lenders assess sole traders on net profit, usually averaged across the last two years of SA302 tax calculations. Some will use the most recent year if the trend is clearly upward. The tension for first-time buyers is that many sole traders legitimately minimise taxable income for tax efficiency, which directly reduces what a lender will offer. If you’re planning to buy in the next 12 months, discuss the trade-off with your accountant before your next return.
Company directors
This is where lender choice makes the biggest difference. Some lenders assess directors on salary plus dividends drawn, others on salary plus a share of net or retained profit. For a director drawing a low salary and leaving profit in the company, the net-profit approach can produce a dramatically higher borrowing figure.
A director taking £12,570 salary and £30,000 in dividends with £60,000 retained in the business looks like a £42,570 earner to one lender and a £72,570 earner to another. At 4.5 times income, that’s the difference between borrowing roughly £191,000 and £326,000. Same person, same figures, completely different outcome. For a first-time buyer trying to reach the price of their first property, that gap can be the difference between buying and not buying.
Contractors
A growing number of lenders assess contractors on their day rate rather than their accounts. A contractor earning £350 per day across 46 weeks produces an annualised income of around £80,500, which is often significantly higher than what their accounts would show. Most lenders require at least 12 months of contracting history and a current contract with several weeks remaining.
Commission and bonus income
Most lenders will consider commission and bonus income, but how much they count varies widely. Some use 100%, others average over two years and discount it. If commission or bonus makes up a large share of your total earnings, the lender you apply to directly affects how much you can borrow.
Commission and bonus income
If you earn from more than one source, such as employed salary plus freelance income, lenders need to see consistency across both. Some will use all of it, others discount or ignore the secondary source. How the income is presented and to which lender can make the difference between approval and decline.
First-time buyers with bad credit: what’s actually possible
Having adverse credit doesn’t automatically lock you out of getting a mortgage, but it does narrow your lender options and may affect your rate. How much it matters depends on what happened, when, and how severe it was.
Minor issues (often manageable):
- A missed payment on a credit card or phone contract more than 12 months ago
- A small default that’s been settled
- Limited credit history (common for younger first-time buyers)
More significant issues (specialist lenders needed):
- Multiple missed payments within the last two years
- Active or recently settled CCJs (County Court Judgements)
- Defaults on larger debts
- An IVA or debt management plan
Serious issues (very limited options):
- Bankruptcy discharged within the last three years
- Mortgage arrears or repossession on a previous property
- Active insolvency
The key principle: the more recent and more severe the issue, the fewer lenders will consider you, and the higher the rate is likely to be. But “fewer” is not “none.” Specialist lenders exist specifically for adverse credit, and a broker who handles these cases regularly knows which ones to approach and how to present the application.
One important point for first-time buyers specifically: limited credit history is a form of adverse credit in some lenders’ eyes. If you’ve never had a credit card, loan, or phone contract in your name, some lenders will struggle to assess your reliability. Building a small credit footprint before applying (a credit card used and paid off monthly, for example) can genuinely help.
How much deposit do you need with complex income or bad credit?
The deposit picture for complex-income first-time buyers is largely the same as for anyone else: 5% is the minimum with most lenders, 10% gives you a wider choice and better rates, and 15% or more opens the strongest deals.
Where it changes is for borrowers with adverse credit. Specialist lenders who accept credit issues typically require a larger deposit, often 15% to 25%, because they’re taking on more risk. The more severe the credit issue, the more deposit you’ll usually need.
If deposit is the barrier, there are options worth knowing about. Gifted deposits from family are accepted by most lenders. Schemes like Shared Ownership let you buy a share of a property with a smaller deposit on that share. Some lenders now offer 100% mortgage products for renters with a strong track record of paying rent on time.
What documents will you need?
Self-employed / sole traders:
- Two to three years of SA302 tax calculations and matching tax year overviews from HMRC
- Three months of personal and business bank statements
- Proof of identity and address
Company directors:
- Two to three years of finalised company accounts (prepared by a qualified accountant)
- SA302s and tax year overviews
- Three months of personal and business bank statements
- An accountant’s reference or certificate
Contractors:
- Current contract showing day rate and remaining term
- Evidence of 12+ months of contracting history
- SA302s if accounts-based assessment is also being considered
- Three months of bank statements
If you have adverse credit, also prepare:
- A clear explanation of what happened and when
- Evidence the issue is resolved (settlement letters, cleared balances)
- Your credit report (check it before your broker does, so there are no surprises)
The mistakes that get complex-income first-time buyers declined
These are the avoidable ones that come up repeatedly:
Applying to the wrong lender. A lender whose policy doesn’t suit your income structure will decline you automatically. The credit search it leaves behind is visible to the next lender and can count against you. This is the single most common cause of unnecessary declines and the single strongest argument for using a broker.
Not knowing how your income will be assessed. If you’re a director assuming the lender will use your net profit, but they only assess salary plus dividends, the affordability calculation collapses. If you’re a contractor assuming day-rate assessment, but the lender requires two years of accounts, the application fails. Understanding how each lender assesses your specific income type before applying is the critical step.
Applying to multiple lenders after a decline. A first decline is frustrating, and the instinct is to try somewhere else immediately. But each application leaves a credit search, and several in a short window signals difficulty. The right response is to stop, understand why the decline happened, and choose the next lender carefully.
Underestimating the impact of a small credit issue. A single missed payment from two years ago might seem trivial, but with some lenders it’s enough to trigger a decline. Checking your credit file before applying means no surprises.
Leaving accounts unfiled or late. If your self-employed accounts aren’t up to date, most lenders won’t proceed. Filing late is a red flag. Get accounts finalised and filed well ahead of any application.
Focusing entirely on the deposit and ignoring other costs. Solicitor fees, surveys, lender arrangement fees, and moving costs add up. Budgeting only for the deposit then discovering an extra £5,000 to £8,000 in costs can derail a purchase.
Why a broker matters more for complex-income first-time buyers
For a PAYE first-time buyer with a clean salary and a 10% deposit, going direct to a bank is a reasonable option. For a first-time buyer with complex income, adverse credit, or both, it is genuinely risky, for three reasons.
First, you don’t know which lenders will assess your income most favourably. A broker who handles these cases daily does.
Second, a decline from the wrong lender damages your position for the next application. A broker’s job is to match you to the right lender first time.
Third, application packaging matters more when the case isn’t straightforward. How the accountant’s reference is worded, how the deposit trail is documented, how a credit issue is explained to the underwriter. These details are the difference between approval and decline on a complex case, and they’re what a good broker handles before the file is even submitted.
"First-time buyers with complex income often come to us after being declined by their bank, assuming the answer is no across the board. It almost never is. The bank assessed their income one way. Another lender would assess it completely differently. I had a first-time buyer last year, a director on a low salary with most of the income sitting as retained profit. His bank offered him half of what he needed. We placed him with a lender that used net profit and the numbers worked comfortably. He bought his first home."

FAQs
Can I get a mortgage as a first-time buyer if I'm self-employed?
Yes. Self-employed first-time buyers apply for the same mortgages as everyone else. The difference is that lenders assess your income from tax returns and accounts rather than payslips, and the number of years of trading history you have affects which lenders are available to you. Most lenders ask for two years of accounts, though some will consider one.
How do lenders assess a first-time buyer with commission or bonus income?
Most lenders will consider commission and bonus income, but how much they count varies. Some use 100%, others average it over two years or apply a discount. If variable income makes up a large share of your earnings, the lender you choose directly affects how much you can borrow.
Can I get a mortgage as a first-time buyer with bad credit?
Yes, depending on the type and timing of the credit issue. Minor issues like a single missed payment more than 12 months ago are manageable with many lenders. More significant issues like CCJs, defaults, or an IVA narrow your options to specialist lenders who typically require a larger deposit and charge higher rates. The more recent and severe the issue, the fewer options available.
Do I need a bigger deposit if I have complex income?
Not necessarily. Complex-income first-time buyers can access the same deposit levels as PAYE buyers, including 5% deposit products with some lenders. Where a larger deposit helps is if you also have adverse credit, where specialist lenders often require 15% to 25%.
What if I've been declined by my bank as a first-time buyer?
A decline from one lender does not mean every lender will say no. Banks assess you against their own criteria, which may not suit how you earn. A whole-of-market broker can identify lenders whose assessment methods fit your income structure. The important thing is not to apply elsewhere immediately, because each application leaves a credit search. Get advice first.
