Getting onto the property ladder in London can feel increasingly out of reach. Rising prices, high rents, and the challenge of saving for a deposit often make buying a home feel like something that’s always just out of reach.

For many buyers, the question isn’t just what to buy - it’s how **to get there in the first place.

New build homes have become a popular option, offering modern living and a simpler buying process. And with models like Keyzy, there are now new ways to access them.

This guide will help you understand whether a new build is right for you - and how Keyzy can help make it more achievable.

New Build vs. Older Property: The Basics

Before we dive into the details, let’s define exactly what we’re looking at:

  • New Build: A property that has been recently constructed and has never been lived in before. These homes are typically part of a wider development and built to modern standards.
  • Older (Resale) Property: These are homes that have been previously owned. They vary wildly in age - from Victorian terraces to houses built just a decade ago - and often come with a "lived-in" history.

Why Do People Choose New Builds?

New builds are particularly popular with first-time buyers and professionals, mainly because they offer convenience and predictability.

  • Move-in ready: There’s no need for renovations or repairs - you can move in immediately.
  • Energy efficient: Modern construction means better insulation and lower energy bills compared to many older homes.
  • Low maintenance: With everything brand new home, you’re less likely to face major repairs in the early years.
  • No chain: New builds usually aren’t part of a property chain, making the process quicker and more certain.
  • Modern design: Open-plan layouts, integrated appliances, and contemporary finishes suit modern lifestyles.

What Are the Downsides of New Builds?

While new builds offer clear advantages, they aren’t perfect for everyone.

  • Price premium: New builds can cost more than similar older properties in the same area.
  • Smaller space: Rooms, storage, and outdoor areas are often smaller than in older homes.
  • Additional costs: Flats and sometimes houses, may include service charges or estate management fees.

Understanding both the benefits and trade-offs is key to making the right decision.

The True Cost of a New Build

The purchase price is only part of the picture. You should also factor in:

  • Service charges (especially for flats)
  • Estate management fees
  • Council tax
  • Utilities (typically lower, but still worth budgeting for)

These costs can vary significantly depending on the development, so it’s important to check them early.

Is a New Build Right for You?

A new build could be a good fit if you:

  • Want a low-maintenance, move-in-ready home
  • Prefer a simple and more predictable buying process
  • Value energy efficiency and modern design
  • Don’t want to deal with renovation work

An older property may suit you better if you prioritise space, character, or the opportunity to add value.

The Biggest Barrier: The Deposit

For many buyers, especially in London, the biggest challenge isn’t choosing a home - it’s saving a deposit.

Even if a new build is the right choice, getting to the point where you can buy one can take years.

This is where alternative models like Keyzy come in.

How Keyzy Helps You Access a New Build

Keyzy is designed to bridge the gap between renting and owning.

Instead of waiting until you have a full deposit, you can move into a new build now and work towards buying it over time.

How it works:

  1. Choose your new build home
  2. Secure it with a product fee
  3. Move in and rent the property
  4. Work towards mortgage readiness
  5. Option to buy at a pre-agreed price, no obligation
  6. Get your rent back as a deposit, if you choose to buy

This allows you to live in your future home while preparing to purchase it.

Why Buyers Consider Keyzy

Keyzy can be particularly helpful if you’re struggling with the upfront barriers to buying.

  • Move in sooner: You don’t need a deposit to get started.
  • Price certainty: The purchase price is agreed at the beginning, helping you plan ahead.
  • Time to prepare: You have time to improve your financial position and mortgage eligibility.
  • Live in the home you plan to buy: Instead of renting elsewhere, you’re already building towards ownership, with the option to ‘try before you buy’.
