Can You Remortgage Your Home to Buy a Rental Property?

Remortgage your home to buy a rental property is one of the most common strategies for first-time and experienced landlords. Many investors use equity in their own home to fund the deposit for a rental purchase — sometimes even buying the property outright.

The good news is that this is a well-established and widely accepted route. If you have enough equity and can meet lender criteria, remortgaging your home can be an effective way to start or grow a rental portfolio.

In this guide, we explain how it works, what lenders look for, the risks to consider, and how to decide whether this strategy suits your goals.

We’re here to help if you’d like to talk through your situation.

Can You Remortgage Your Home to Buy a Rental Property?

Yes — many lenders allow you to release equity from your residential home to use as the deposit for a rental property.

Lenders normally ask:

• What the released funds will be used for
• How much equity you’re taking
• Your income and affordability
• Whether you plan to keep living in your current home
• Whether you have any existing buy-to-let properties

As long as affordability fits their criteria and the loan-to-value (LTV) remains within acceptable limits, using equity for a rental purchase is perfectly achievable.

How Does Remortgaging to Buy a Rental Property Work?

The process typically involves:

1. Valuing your home

A lender or surveyor confirms your current property value.

2. Assessing your current mortgage balance

This determines how much equity you have available.

3. Releasing equity

You increase your residential mortgage or switch to a new lender who offers a higher loan.

4. Using the released funds as a deposit

This deposit is then used for your buy-to-let mortgage application.

5. Completing the buy-to-let purchase

The buy-to-let lender assesses rental income, deposit, and your wider financial profile.

This can all be done simultaneously so both mortgages complete in the correct order.

How Much Equity Do You Need to Release?

The amount you need depends on:

• Property prices in your chosen rental area
• The type of buy-to-let lender
• The required deposit

Typical buy-to-let deposit expectations include:

• 20–25% deposit for standard buy-to-let
• 25–30% for applicants with complex credit
• 30%+ for specialist property types

If your rental plans involve new builds, HMOs, or short-term lets, deposit expectations may increase.

How Lenders Assess the Remortgage Affordability

Residential lenders run standard affordability checks when you remortgage your home. They review:

• Your income
• Your existing mortgage
• Credit commitments
• Household bills
• Dependants
• Outgoings shown on bank statements

Your intention to use the equity for a rental property doesn’t typically affect affordability, but they will want to understand the purpose of the funds.

Some lenders decline if you have multiple buy-to-lets already, while others are more flexible.

How Buy-to-Let Lenders Assess the Rental Purchase

Once the equity is released, the buy-to-let mortgage must pass its own affordability test.

Buy-to-let lenders look mainly at:

Rental coverage

Typically 125–145% coverage of the stressed mortgage payment.

Stress-test interest rate

Different lenders use different notional interest rates.

Property type and rental demand

The valuer confirms expected rent and property suitability.

Your personal income

Used to support voids, maintenance and unexpected costs.

Your wider financial profile

Including credit history and existing mortgages.

We cover these calculations in more detail in our guide on how lenders assess rental income.

Can You Remortgage Your Home to Buy a Rental Property as a First-Time Landlord?

Yes — this is one of the most common routes for first-time landlords.

However, lender criteria can be stricter. They may look more closely at:

• Your deposit size
• The rental income on the new property
• Your income stability
• Whether you already own a residential property (you do)

Being a homeowner strengthens your profile significantly.

We explore this further in our guide on buy-to-let options for first-time landlords.

---

Can You Use a Limited Company After Releasing Equity?

Yes — you can release equity from your personal home and purchase the rental property through a limited company.

This is common among portfolio landlords and higher-rate taxpayers.

Some key points:

• The residential remortgage remains in your personal name
• The buy-to-let mortgage is issued to your limited company
• You usually act as a personal guarantor

This creates a clear split between your home and your investment business.

We cover this in more detail in our guide on limited company vs personal name for buy to let.

How Adverse Credit Affects Your Ability to Remortgage for a Rental Property

Adverse credit does not necessarily prevent a remortgage or buy-to-let purchase.

Residential remortgage

Lenders vary in their tolerance. Mild issues may be acceptable. Severe issues may require a specialist lender.

Buy-to-let

Specialist lenders are often more flexible, especially if:

• Rental income is strong
• Deposit is larger
• Credit issues are historic

We explain this in more detail in our guide on how adverse credit affects your buy-to-let options.

Risks to Consider Before Releasing Equity

Releasing equity can be effective, but it increases borrowing on your home. Consider the risks:

Your monthly payments may increase

Depending on the mortgage rate and amount borrowed.

Your loan-to-value will rise

This could affect future remortgage options.

Rental voids

If your rental property sits empty temporarily, you still need to cover your home mortgage.

Property market fluctuations

Both your home and rental property values may change over time.

It’s important to ensure the numbers work reliably, even with conservative rental estimates.

Let’s explore your options together.
