Consent to Let vs Let to Buy: Why a Let to Buy Mortgage Is Often the Smarter Move
You’re moving house but don’t want to sell your current home. It may not be the right time to sell, or perhaps you may see its potential as a long-term investment. Either way, you’re thinking: “Can I rent it out?”
Two options typically arise: a Consent to Let or a Let-to-Buy mortgage.
Getting Consent from your existing lender is the most straightforward route. However, if you’re seeking flexibility, better financial terms, and long-term planning, a Let to Buy remortgage often proves to be the best option.
In this blog, we’ll break down both options, highlight the key differences, and explain why more homeowners are turning to Let to Buy mortgage brokers, such as Pinpoint Finance, to make the move work.
What Is Consent to Let?
Consent to Let is when your residential mortgage lender gives you temporary permission to rent out your home, without having to switch to a formal Buy-to-Let product.
Sounds easy enough. But there are limitations:
- It’s usually only granted for 12 to 24 months, or when your mortgage product ends
- Your lender isn’t obligated to say yes
- Many lenders apply a surcharge to your interest rate, often 1% or more
- You’ll likely stay on a repayment mortgage, meaning higher monthly outgoings
Consent to Let is best suited for short-term scenarios, such as temporarily relocating or trying life as a landlord.
What Is a Let-to-Buy Mortgage?
A Let to Buy Mortgage allows you to remortgage your current property onto a buy-to-let style mortgage while simultaneously taking out a new residential mortgage for your onward purchase.
This setup means you can:
- Rent out your current home legally and long-term
- Release equity from your existing home to use as a deposit
- Benefit from interest-only repayments on the rental property
- Access better rates, incentives, and affordability assessments
It’s a popular strategy for homeowners who want to move into a new house, retain their existing property, and start or expand a rental portfolio.
Let to Buy vs Consent to Let: Key Differences
| Feature | Consent to Let | Let to Buy Mortgage |
|---|---|---|
| Term | Temporary (12–24 months) | Long-term to maturity of the mortgage |
| Lender discretion | Must be requested and approved | Full remortgage, not reliant on permission |
| Interest rate | Often increased with a surcharge | Competitive Let to Buy rates available |
| Repayment type | Typically repayment | Interest-only options available |
| Equity release | Not available | Can use equity for the next deposit |
| Affordability | Based on household income | Based on the rental income of the property |
| Regulation | No additional protection | Regulated under Consumer Buy to Let rules |
| Early Redemption Charges (ERC) | Not usually payable | Maybe payable if you redeem your mortgage early |
Why Let to Buy Could Make More Sense
1️⃣ Interest-Only = Lower Monthly Payments
One significant advantage of Let to Buy is access to interest-only mortgages, which reduce your monthly payments and improve your cash flow. Consent to Let keeps you on your current repayment structure, which can be costly once you factor in increased rates and rental property expenses.
2️⃣ Market Rent Determines Affordability
With Let to Buy, lenders assess affordability based on the expected rental income of the property, not your personal salary. This is ideal for:
Releasing equity
- Homeowners needing flexibility on their new mortgage
3️⃣ Attractive Rates and Lender Incentives
Let to Buy mortgages are competitive. Lenders often offer:
Better rates than you’d get sticking with Consent to Let
Incentives like free valuations, no legal fees, or cashback
A smoother process with reduced stress tests for like-for-like remortgages
It’s not just smarter, it could be cost-effective.
4️⃣ Extra Protection with Consumer Buy to Let
Let-to-Buy mortgages are typically regulated under Consumer Buy-to-Let legislation. This offers:
More transparency and protections
An obligation on the lender or broker to ensure suitability
Support if anything goes wrong
With Consent to Let, you’re more exposed, and technically operating a rental under a mortgage not designed for it.
💡 Top Tip: Consent to Let Often Leads to a Dead End
Many people start with a Consent to Let, thinking it’ll buy them time. But when that short-term permission runs out, they’re forced to either sell or switch to a Buy to Let mortgage, often under pressure, with fewer lender options.
A Let to Buy mortgage allows you to plan long-term from the outset, giving you more control and financial clarity.
Don’t Just Let – Let Smart!
If you’re planning to move house, keep your current property, and rent it out, a Let to Buy mortgage offers:
Lower payments
Better affordability rules
Longer-term stability
Consumer protection
And a far smoother process
Consent to Let might feel simpler, but it’s often more expensive, restrictive, and ultimately, a short-term patch.

Final Thoughts: There’s No One-Size-Fits-All
While a Let to Buy mortgage often presents clear financial advantages, it’s not always the best fit for everyone. Your situation, mortgage terms, equity levels, and future plans can all influence the best way forward. We also need to consider Stamp Duty Land Tax when buying a second home.
Similarly, Consent to Let may still be the right choice in some particular scenarios. But relying on guesswork, assumptions, or generic online advice can lead to costly mistakes and missed opportunities.
That’s why it’s so important to speak with a specialist mortgage broker who understands let to buy mortgages.
