Buying a home, step by step
Buying a home in the UK, from saving a deposit to the day you get the keys: every step, every cost, and a free calculator for each one.
Quick answer
Buying a home in the UK usually follows the same path: save a deposit, check what lenders could lend you, get a mortgage in principle, find a home and make an offer, then apply for the mortgage while your solicitor does the legal work. On completion day you get the keys.
Plan for more than the deposit. Stamp Duty, legal fees, a survey and any mortgage fees all need paying too, and the size of your deposit decides your loan to value band, which decides the rates you are offered.

The bigger the deposit, the lower the rate
Each step down in loan to value usually brings a lower rate. The calculators show what each one saves.
Buying a home, step by step
- Save your deposit. Most lenders need at least 5% of the price, and a bigger deposit opens up lower rates. See how to save for a house deposit.
- Check what you could borrow. Lenders look at your income, your outgoings and your deposit. See how much you can borrow.
- Get a mortgage in principle. A lender’s early indication of what it may lend, which estate agents often ask to see. See mortgage in principle.
- Find a home and make an offer. Once it is accepted, instruct a solicitor or conveyancer.
- Apply for the mortgage. The lender checks your documents and values the home. You may also want your own survey.
- Exchange and complete. Contracts are exchanged, then on completion day the money moves and you get the keys. Stamp Duty is paid around this time.
What buying a home costs
On top of the deposit, budget for property tax, legal fees, a survey and any mortgage fees. In England and Northern Ireland, first time buyers pay no Stamp Duty on homes up to £300,000. See Stamp Duty for first time buyers for your figure, and Scotland and Wales, which have their own taxes.
| Cost | Amount |
|---|---|
| Deposit (10%) | £30,000 |
| Stamp Duty | £0 |
| Legal fees (estimate) | £1,500 |
| Survey (estimate) | £600 |
| Total cash needed | £32,100 |
Your deposit and your rate
Lenders price mortgages in loan to value bands: 95%, 90%, 85% and so on down to 60%. Moving down a band usually brings a lower rate, so a slightly bigger deposit can cut your monthly payment for years. The live table above shows today’s averages for each band, and Theo’s deposit planner shows exactly how much you need to reach the next one.
Help with a deposit
Family can give you some or all of the deposit as a gift, and lenders will want a letter confirming it is not a loan. A Lifetime ISA adds 25% to what you pay in, up to £1,000 a year, for first homes up to £450,000, and the account must be open for 12 months before you buy. Shared ownership lets you buy a share of a home with a deposit on just that share. An FCA-authorised mortgage adviser can tell you which lenders accept each of these.
Your monthly payment
Your payment depends on the amount you borrow, the rate and the term. The mortgage repayment calculator shows yours, the total interest and what overpaying could save. Before you fix, see whether to fix for 2 or 5 years and which way rates are heading.
