Let-to-Buy vs Buy-to-Let: Key Differences Explained. When moving home or investing in property, it’s essential to understand the difference between let-to-buy and buy-to-let mortgages. Both options involve letting a property, but they serve different financial goals and borrower circumstances.
What Is Let-to-Buy?
Let-to-buy involves remortgaging your current home to let it out, while simultaneously buying a new residential property to live in. It’s a strategy often used by homeowners who want to move but keep their existing property as a rental.
Let-to-buy may be a good fit if:
- You want to keep your home as an investment.
- You need to unlock equity from your current home to use as a deposit.
- You’re relocating for work or lifestyle reasons.
Let-to-buy requires two mortgages:
- A let-to-buy mortgage for your existing home.
- A new residential mortgage for the property you intend to live in.

What Is Buy-to-Let?
Buy-to-let is designed for those who purchase a property specifically to rent it out. It’s a popular strategy for investors and landlords.
Key features of a buy-to-let mortgage include:
- Based primarily on expected rental income.
- Often, it is in the interest of reducing monthly payments.
- Requires a larger deposit, usually at least 25%.
Buy-to-let is suitable if:
- You’re starting or expanding a rental property portfolio.
- You do not intend to live in the property.
- Your income meets the affordability criteria.

Key Differences: Let-to-Buy vs Buy-to-Let
| Feature | Let-to-Buy | Buy-to-Let |
|---|---|---|
| Purpose | Move and rent current home | Buy to rent out |

Important Considerations
Affordability and rental calculations play a critical role in both mortgage types. Lenders assess rental income potential and may stress-test affordability using interest rate buffers. Working with a qualified adviser helps you understand your borrowing limits and tax implications.
Keep in mind:
- Let-to-buy is usually time-sensitive due to simultaneous transactions.
- Buy-to-let lenders often require a minimum annual income, even when the rental yield is strong.
- Stamp duty rules apply differently to second properties. Seek tax advice if unsure.
To understand how your existing mortgage, credit profile, or deposit may affect your options, speak to a qualified mortgage broker. Contact us for a tailored review.
Is Let-to-Buy Right for You?
Let-to-buy might suit you if you’re moving but not ready to sell your current home. It can be a stepping stone into property investment without giving up ownership.
It may also benefit those:
- Moving to a new area temporarily.
- Planning to return to their original home in the future.
- Looking to generate rental income alongside a new mortgage.
Is Buy-to-Let More Suitable?
Buy-to-let is a better fit if your intention is long-term investment. It offers flexibility to manage multiple properties and income potential tied to market rents.
If you’re focused on:
- Building a property portfolio.
- Earning rental yield.
- Not needing the property as a residence.
Then buy-to-let mortgages may align better with your goals.

It may be possible, depending on the lender’s criteria and your equity. Specialist lenders are available, but terms may be more limited.
