I Earn £100k - What Home Can I Realistically Afford?

If you earn £100,000 a year, you are officially among the top earners in the UK. However, despite being in the high-income bracket, the reality of the current property market can still feel daunting. With average house prices in many desirable areas sitting at multiple times the average salary, even a six-figure income faces hurdles like strict stress-testing and the "deposit trap."

The good news?

You have significant buying power. Whether you choose a traditional mortgage or a modern path like rent-to-own, a £100k salary opens doors to premium properties.

1. How Lenders Calculate What You Can Borrow

Most mortgage lenders use a straightforward income multiple:

You can typically borrow 4.0x – 4.5x your annual income

(With some lenders willing to go higher in the right circumstances, subject to affordability checks.)

On a £100,000 salary, this gives you a borrowing range of:

£400,000 - £450,000 mortgage potential

If you are buying with a partner, these figures can scale even higher, but as a solo applicant, a £100k income provides a very robust foundation.

2. How Much Deposit You’d Need

For a standard first-time buyer mortgage, most lenders require 5%–15% of the property value as a deposit.

Here’s what that looks like in practice:

For many professionals, saving £60k+ while living in high-cost areas like London can take years, even on a great salary. This is why high earners are increasingly looking at private rent-to-own as a way to "skip the queue."

3. Solving The Deposit Challenge

If you have the income but not the lump sum, rent-to-own models like Keyzy allow you to secure a home without the years of aggressive saving.

Instead of waiting years to save a deposit (while house prices potentially rise), you move in now and build your equity through your monthly payments.

4. How Rent-to-Own Works

With rent-to-own, you:

• Move In Immediately: Choose the home you want.
• Fixed Rent: Pay a set monthly amount for 2 years, no rental increases.
• Rent to Deposit: 100% of your rent is credited toward your deposit if you choose to buy.
• Lock in the Price: You agree on the purchase price on day one, protecting you from future market spikes.
• Flexibility: You have the right to buy the home, with no obligation to do so.

There’s no upfront deposit, no sudden rent increases, and no pressure to commit before you’re ready.

It’s a strong option for high earners who want flexibility without putting homeownership on hold.

5. Real Example: What £100k Buys with Rent-to-Own

Let’s look at a realistic scenario for a professional working in the City: • Salary: £100,000 • Location: West London • Home Type: 3-bed premium apartment • Upfront Deposit: £0 • Monthly Payment: £2,700 • Potential Home Value: £714,200 • Rent Credited Back (after 2 years): £64,800

The Outcome: You live in a £714k home today, build a meaningful deposit through rent, and buy in just two years - all while avoiding "dead rent" and the stress of saving a lump sum from scratch.

6. The Bottom Line: Your Income is Your Greatest Asset

Earning £100,000 puts you in a position of power, but you need to choose the strategy that fits your timeline.

• Choose a Traditional Mortgage if you already have a large cash deposit. • Choose Rent-to-Own if you’re earning well but struggling to save a large deposit, recently moved to the UK or are self-employed, facing strict mortgage eligibility, needing more flexible criteria than traditional lenders, wanting certainty on future purchase price, not ready to commit without living in the home first, or want to stop “dead rent” and build equity instead.
