First-Time Buyers UK: Deposits, Mortgages, Schemes and Buying Costs

A first-time buyer hub covering deposits, affordability, mortgage applications, government schemes, buying costs, and the key decisions before you buy your first home in the UK.

Most first-time buyers do not need more noise. They need a clear order for the decisions that actually matter: how much deposit to build, what purchase price is realistic, which schemes still help, how the mortgage application works, and what the total buying cost looks like beyond the deposit. This hub brings that route together so readers can move from first-home questions to practical next steps without bouncing between disconnected mortgage guides.

Use this as the main starting point for the PocketWise first-time-buyer cluster. It connects the core guides on deposit building, affordability, mortgage applications, first-time-buyer schemes, 5% deposit deals, buying costs, and the practical trade-offs around getting onto the property ladder.

If the key question is how to use tax-efficient savings for a deposit, use the ISAs hub. If you mainly need purchase-tax thresholds and rules, start with Stamp Duty Rates 2026/27. For the wider section, return to Mortgages & Property.

Where to start

First-time buyers usually need answers in this order:

  • are you financially ready to buy yet
  • how much deposit do you need and how long will it take to save
  • what can you realistically afford based on income and monthly costs
  • which schemes still exist and which are actually useful
  • how the mortgage and buying process works from agreement in principle to completion

The guides below are arranged around those questions.

Start with readiness, not Rightmove

The biggest first-time-buyer mistake is treating the deposit as the only barrier. In practice, readiness usually depends on a few separate checks:

  • stable income and clean enough recent bank statements
  • deposit plus a separate cash buffer for fees and moving costs
  • monthly payments that still work if rates stay higher than expected
  • a credit file that will not narrow lender choice unnecessarily

That is why the best first step is usually not house hunting. It is working out whether the full budget stands up.

Start here:

If those numbers do not work yet, the next lever is usually more deposit, a lower target price, or more time.

Deposit size changes more than just the hurdle

Most buyers focus on the minimum 5% deposit because that is the threshold that gets them into the market. But deposit size also affects the mortgage rate, the range of lenders available, and how resilient the purchase feels if house prices or rates move.

For many buyers, the real decision is not just “Can I scrape together 5%?” It is:

  • should I buy sooner with a smaller deposit and higher monthly cost
  • should I wait longer for 10% or 15%
  • is a Lifetime ISA boosting the deposit faster than an ordinary savings route

Use these guides:

That sequence helps readers decide whether speed or borrowing strength matters more in their case.

Affordability is about payments, not just income multiples

First-time buyers often start with a simple salary multiple, but lenders do not stop there. They look at committed spending, childcare, loans, credit cards, dependants, and whether the payment still looks manageable if rates stay above today’s teaser deals.

That makes the useful question slightly different from “What is the biggest mortgage I can get?” The better question is “What purchase price still leaves enough room for repairs, furniture, council tax, insurance, and normal life?”

Schemes matter, but they are not all equally useful

The first-time-buyer market still contains a lot of outdated scheme language. Many readers search for Help to Buy even though the old England equity-loan route is gone. What matters now is understanding the live routes that still change the maths:

  • Lifetime ISA for deposit building
  • First Homes for discounted purchases in eligible developments
  • Shared Ownership where full purchase is not affordable yet
  • 95% mortgages where deposit is the main barrier

Use:

The practical value of a hub here is that schemes only make sense when combined with deposit size, borrowing power, and buying costs. A scheme that solves one problem can still leave the total purchase unaffordable.

The mortgage application is where preparation pays off

By the time a first-time buyer applies, most of the hard work is already done. The application stage is really about presenting the case clearly:

  • deposit evidence is traceable
  • income documents are complete
  • bank statements do not create avoidable questions
  • the chosen property fits lender criteria
  • credit issues are understood before the full application goes in

Use:

If the real problem is credit history rather than process, add Buying a House with Bad Credit before applying.

Budget for the purchase, not just the offer price

The fastest way for a first-time-buyer budget to break is forgetting that the deposit is only one part of the cash requirement. Surveys, legal fees, mortgage fees, removals, furnishings, and immediate repairs often matter as much as the headline purchase price.

That is also where stamp duty matters. Many first-time buyers pay nothing because of relief, but not everyone qualifies, and thresholds differ across the UK.

FAQ

What is the best place to start as a first-time buyer in the UK?

Usually with deposit size, total buying costs, and a realistic affordability check before looking at properties.

Is 5% enough for a first-time buyer deposit?

Sometimes, yes. But 10% or more usually improves lender choice and lowers monthly repayments.

Which scheme helps most first-time buyers?

For many buyers, the Lifetime ISA remains the most broadly useful support because the 25% bonus directly boosts the deposit. First Homes and Shared Ownership are more situational.

Should I wait to save a bigger deposit?

Often that depends on whether waiting meaningfully improves the mortgage rate and monthly payment, and whether local house prices are moving faster than the extra savings.
