First-Time Buyer Guide UK: From Zero to Keys in Your Hand

Buying your first home in the UK is one of the most financially complex things you will ever do. Most people go into it without understanding half of the costs, the process, or the traps. Here is the entire journey — from the moment you decide you want to buy, to the day you collect your keys.

Stage 1: The Deposit

The minimum deposit for most residential properties is 5 percent. However, a 10 to 15 percent deposit unlocks meaningfully better mortgage rates — the difference over a 25-year term can be tens of thousands of pounds in interest. Build your deposit using a combination of a Lifetime ISA (25 percent government bonus on contributions up to £4,000 per year), regular savings in a high-interest easy-access account, and any gifts from family.

Remember: the deposit is not your only upfront cost. Budget an additional £5,000 to £12,000 for transaction costs.

Stage 2: Mortgage in Principle

Before you start viewing properties seriously, get a Mortgage in Principle (MIP) from a lender or broker. This is a conditional agreement that, subject to final checks, a lender will provide you with a mortgage up to a stated amount. Estate agents and sellers take offers more seriously from buyers who have an MIP. It does not affect your credit score in most cases — a soft credit check is typically used.

Use a fee-free mortgage broker. They have access to the whole market, including deals not available directly, and they are paid by the lender not by you.

Stage 3: The Search and Offer

Once you have viewed a property and want to make an offer, the offer is made verbally through the estate agent and confirmed in writing. There is no legal commitment at this stage — either party can walk away. Sealed bids (best and final offers by a deadline) are common in competitive markets.

Do not skip the survey. A Level 2 homebuyer survey costs £400 to £900 but can identify issues that allow you to renegotiate the price — or walk away from a money pit. A Level 3 full structural survey is recommended for older or unusual properties.

Stage 4: The Hidden Costs

Beyond the deposit, budget for:

• Stamp Duty: first-time buyers pay 0% on the first £425,000, then 5% up to £625,000. Above £625,000, standard rates apply. These thresholds are subject to change.
• Solicitor/conveyancer fees: £800 to £1,500 typically
• Survey: £400 to £900 for a Level 2
• Mortgage arrangement fee: often £999 to £1,499, sometimes added to the mortgage
• Valuation fee: £150 to £300, sometimes free with certain mortgage deals
• Removal costs: £500 to £1,500 depending on distance and volume
• Land Registry fee: £20 to £910 depending on property value

Stage 5: Exchange and Completion

Exchange of contracts is the legally binding stage — once both parties have signed and exchanged, neither can pull out without significant financial penalty. Building insurance must be in place from the date of exchange, not completion.

Completion typically happens one to four weeks after exchange. On completion day, the remaining purchase funds are transferred, the keys are released, and you own the property.

The Bottom Line

First-time buying is complex. But it is a learnable process. Every stage has clear steps and known costs. Go in with your eyes open, with your finances in order, and with a good broker and solicitor working for you.
