Buying your first home in Cambridge is exciting, and the mortgage is usually the part that feels most daunting. It matters more here than in most of the country, too: Cambridge house prices sit well above the national average, driven by two universities, the biomedical campus and the wider "Silicon Fen" tech cluster, all competing for a limited supply of homes. Get your borrowing right and you can move quickly and confidently when the right property appears; get it wrong and you risk being outpaced in a fast market. This guide walks you through the essentials.

Key takeaways

  • Most lenders offer around four to four and a half times your income; in Cambridge, where prices are high, the size of your deposit does a lot of the heavy lifting.
  • First-time buyers pay no Stamp Duty up to £300,000 and 5% between £300,000 and £500,000 — and because many Cambridge homes exceed £300,000, you should budget for a bill.
  • An agreement in principle makes you a credible buyer in a competitive market.
  • Schemes like the mortgage guarantee (5% deposit), the Lifetime ISA and Shared Ownership can bridge the gap in a pricey city.

Work out what you can realistically borrow

Before you fall for a listing, get a firm grip on your finances. Lenders decide how much to offer based on your income, your regular outgoings and your overall financial reliability, and as a rough guide many will lend around four to four and a half times your income. Your deposit matters just as much: the more you put down, the better the interest rates you are offered, and the further your budget stretches. Five per cent deposits are possible through the government's mortgage guarantee scheme, but in a market as expensive as Cambridge, a larger deposit genuinely changes what you can buy — the difference between a one-bedroom flat and a small terraced house.

It helps to know where first-time buyers actually get a foothold in the city. More affordable homes tend to cluster in areas like Arbury, King's Hedges and parts of Cherry Hinton, along with the Victorian terraces of Romsey, while the new-build developments at Eddington, Darwin Green and Great Kneighton (Trumpington) offer modern, energy-efficient options, often with Shared Ownership available. Knowing your realistic price band before you start saves a lot of heartache later.

Get an agreement in principle early

An agreement in principle (sometimes called a decision in principle) is a statement from a lender indicating roughly how much they would lend you. It is not a full mortgage offer, but it is quick to arrange and genuinely useful. It tells you your realistic budget, and it shows estate agents and sellers that you are a serious buyer who can proceed. In a city where a well-priced home can attract several offers within days, having an agreement in principle ready can be the difference between securing a property and missing out.

Understand the main types of mortgage

Mortgages come in a few broad shapes, and knowing the difference helps you choose what suits you:

  • Fixed-rate: your interest rate is locked for a set period, often two or five years, so your payments stay predictable whatever happens to rates.
  • Tracker: your rate follows the Bank of England base rate, which stands at 3.75% as of autumn 2026, plus a set margin, so payments can rise or fall.
  • Standard variable rate (SVR): the lender's default rate, which you move onto when a deal ends. It is typically much higher, so most buyers remortgage before reaching it.

Most mortgages today are repayment mortgages, where you pay off both the loan and the interest so you own the home outright at the end of the term. The impartial MoneyHelper service has useful calculators if you want to model the numbers.

Budget for stamp duty — it bites in Cambridge

The deposit and monthly payments are only part of the picture. The biggest extra cost is usually Stamp Duty Land Tax. First-time buyers pay nothing on the first £300,000 and 5% on anything between £300,000 and £500,000, with no relief at all above £500,000. This matters especially in Cambridge: with the average first-time-buyer home comfortably above £300,000, a good number of local buyers will face a stamp duty bill that someone buying in a cheaper region would not. On a £400,000 home, for example, that is 5% of £100,000 — a £5,000 bill to plan for. You can check the exact figures on the gov.uk Stamp Duty page. On top of that, allow for a survey, legal and conveyancing fees, any mortgage arrangement fee, and the move itself — our guide to the true cost of moving home breaks these down.

Explore the help available to first-time buyers

Several schemes are designed to give first-time buyers a leg up, and in a high-priced city they are worth knowing. The mortgage guarantee scheme supports 95% mortgages, so you can buy with a 5% deposit. A Lifetime ISA adds a 25% government bonus to your savings, up to £1,000 a year, provided the home costs £450,000 or less — a threshold that still covers a large share of Cambridge's first homes. Shared Ownership, widely available on the city's newer developments, lets you buy a share of a property and pay rent on the rest, lowering the deposit and mortgage you need. The First Homes scheme offers discounts on selected new-build homes. Each has its own eligibility rules, so check which fit your circumstances.

Lean on good local advice

A mortgage is likely the biggest financial commitment you will make, so it pays to have the right people alongside you. A good mortgage broker can search the whole market, explain your options in plain English and find deals you might not reach on your own. Pair that with an estate agent who knows the Cambridge market street by street, and you have the guidance to move quickly and sensibly when the right home appears.

To wrap up

Getting mortgage-ready is mostly preparation: know what you can borrow, hold an agreement in principle, pick the mortgage type that fits, and budget for stamp duty and fees as well as the deposit. Do that groundwork and the rest of the purchase feels far less intimidating.

FAQ

How big a deposit do I need to buy in Cambridge?

You can buy with as little as a 5% deposit through the mortgage guarantee scheme, but a larger deposit unlocks better rates and widens your options. Given Cambridge's high prices, saving as much as you comfortably can is well worth it, and schemes like the Lifetime ISA can help you get there faster.

Do first-time buyers pay stamp duty in Cambridge?

Often, yes. First-time buyers pay no stamp duty up to £300,000 and 5% between £300,000 and £500,000. Because many Cambridge homes exceed £300,000, plenty of local first-time buyers will have some to pay and should budget for it.

Where can first-time buyers afford to buy in Cambridge?

More affordable homes tend to be found in areas such as Arbury, King's Hedges and Cherry Hinton, and on newer developments like Eddington, Darwin Green and Great Kneighton, where Shared Ownership is often available. A local agent can point you to the areas that fit your budget.
