First-time buyer mortgages for contractors

Contractors can absolutely buy a first home — the difficulty is almost never the deposit or the income, it's finding a lender that reads a day rate correctly. The right lender annualises your gross contract rate rather than working from minimised tax-return profit, which typically lifts your borrowing substantially. Everything else — deposit, credit, affordability — works the same as it does for an employee.

Can contractors get a first-time buyer mortgage?

Answer first: yes — and the obstacle is almost never what people assume. It isn’t the deposit, and it isn’t that your income is too small. It’s that many lenders assess self-employed applicants from tax-return profit, which is legitimately minimised for tax and makes a strong earner look modest. Apply to the wrong lender and you get a disappointing figure or a decline; apply to the right one and you’re an attractive applicant.

The lenders that work well for contractors use contract-based underwriting: they read the contract in front of you and price the mortgage off your gross day rate. That single difference is what turns “I can’t borrow enough” into a workable purchase. Everything else about buying your first home — deposit, credit checks, valuation, conveyancing — is the same as it is for anyone. Our first-time buyer page sets out the full route.

How will a lender work out what you can borrow?

The right lender annualises your day rate. The standard method is day rate × days worked per week × roughly 46 weeks — the 46 deliberately builds in a buffer for gaps between contracts — and then applies an income multiple, commonly around 4.5. The mechanics are explained in the annualised contract rate, and you can see the effect on your own numbers with the contractor mortgage calculator.

Compare that with the alternative. A lender working from your accounts might see a modest net profit — perfectly legitimate, but nothing like your real earning power. The same person, on the same income, can be quoted wildly different figures by two lenders. For a first-time buyer trying to work out what they can afford, that gap is the whole ball game.

How much deposit do you actually need?

The same as an employee. Deposits generally start at around 5% of the purchase price, and the more you put down the better the rates you can access, because your loan-to-value falls. There’s no rule requiring contractors to put down more — that only appears to be true when a lender undervalues your income and therefore caps how much it will lend.

If your deposit is on the smaller side, it’s worth understanding the low-deposit schemes available, which are designed exactly for buyers in your position. And if you’re weighing how deposit size changes your monthly cost, model it on the repayment calculator before you commit to a price bracket.

What documents will you need?

Fewer than most contractors expect. Typically: your current contract, recent bank statements, proof of identity, and — depending on your structure and the lender — accounts or an accountant’s reference. A company director may evidence salary, dividends and retained profit; a CIS subcontractor provides CIS payslips showing gross income.

The point is that the right lender asks for evidence that reflects how you actually earn, rather than paperwork designed for employees. Our contractor document checklist breaks this down by income type so you can gather it before you apply.

Do you need years of accounts?

Often not. The belief that you need two or three years of filed accounts keeps a lot of capable first-time buyers renting unnecessarily. Many contractors are assessed on their current contract, and a number of lenders will work from one year’s figures. If your trading history is short, mortgages on one year of accounts sets out the routes, and mortgages without an SA302 covers the evidence question directly.

What strengthens a short history most is continuity — showing that your contracting is a continuation of established experience in the same field, not an untested new venture. If you moved from employment into contracting in the same line of work, say so clearly; it reassures lenders considerably.

Get an Agreement in Principle — from the right lender

Before you start making offers, get an Agreement in Principle. It tells estate agents you’re a serious buyer, and in a competitive market that matters.

But get it from a lender that already understands contract income. An AIP from a high-street process that shrinks your day rate gives you a number that’s both discouraging and wrong — and you may make decisions (about price bracket, or whether to buy at all) based on a figure that a suitable lender would never have produced. This is the single most valuable thing a whole-of-market broker does at this stage: makes sure the first number you see is the real one.

What if you’re a director, umbrella worker, or on CIS?

The same principle applies, adapted to how you’re paid. A limited company director may be assessed on salary plus retained profit rather than just the small salary and dividends drawn. An umbrella or inside-IR35 contractor should be assessed on the gross contract value, not the reduced net pay after deductions. A CIS subcontractor should be read on gross income before the 20% deduction.

In each case, the theme is identical: somewhere in the market is a lender set up to read your income as it really is. Finding that lender is the job.

The bottom line

Contractors can buy a first home on the same deposits and the same terms as anyone else — provided the lender reads a day rate properly. Get an Agreement in Principle from a contractor-friendly lender before you offer, gather your contract and statements early, and don’t let a high-street quote based on tax-return profit tell you what you can afford.
