Remortgage as a Landlord

How Buy-to-Let Remortgages Work for Landlords

A buy-to-let remortgage works in a similar way to a residential remortgage, but there are some important differences in how lenders assess your application. The primary focus for buy-to-let lending is the rental income generated by the property rather than your personal income, although personal income may also be considered.

When you remortgage a buy-to-let property, lenders will carry out a rental coverage calculation to ensure the rent covers the mortgage payments by a sufficient margin. This is known as the Interest Coverage Ratio or ICR, and most lenders require the rental income to be at least 125% to 145% of the mortgage interest payments at a stressed rate.

The stressed rate is a higher interest rate used by lenders to ensure that you could still afford the mortgage if rates were to rise. This is typically set at around 5% to 5.5%, although some lenders use different stress rates depending on the product and your tax status.

For example, if your monthly mortgage interest payment at the stressed rate would be 1,000 pounds, a lender requiring 145% rental coverage would need your monthly rental income to be at least 1,450 pounds. If the rent does not meet this threshold, you may need to put down a larger deposit or look for a lender with less stringent criteria.

Unlike residential mortgages where lenders typically offer up to 90% or 95% loan-to-value, buy-to-let remortgages generally have a maximum LTV of 75% to 80%. Some specialist lenders may go higher, but you will usually need at least 20% to 25% equity in the property.

It is also important to note that buy-to-let mortgages are usually arranged on an interest-only basis, meaning your monthly payments only cover the interest and the capital balance remains unchanged. You will need to demonstrate a credible repayment strategy for how you intend to repay the capital at the end of the mortgage term.

Rental Income Assessment and Affordability

Understanding how lenders assess rental income is crucial for landlords looking to remortgage. The approach can vary depending on the lender, your tax status and the number of properties you own.

Basic rate taxpayers generally benefit from more favourable rental coverage calculations. Many lenders require the rental income to be at least 125% of the mortgage payment at the stressed interest rate for basic rate taxpayers. This lower threshold can make it easier to qualify for a remortgage.

Higher rate taxpayers face stricter criteria because they receive less tax relief on mortgage interest costs. Most lenders require rental coverage of at least 145% of the mortgage payment at the stressed rate for higher rate taxpayers. This higher threshold reflects the reduced tax efficiency of buy-to-let investment for those in higher tax brackets.

When calculating your rental income, lenders will typically look at the current market rent for the property. They may ask for a rental valuation from a qualified surveyor or use data from the letting agent managing the property. If the property is currently vacant, lenders will assess what it could reasonably achieve on the open market.

Some lenders will also consider your personal income alongside the rental income. This can be beneficial if the rental income alone does not quite meet the coverage requirements, as strong personal earnings can provide an additional layer of comfort for the lender.

If you have existing debts, other mortgage commitments or credit issues, these will also be taken into account during the affordability assessment. Lenders want to be satisfied that your overall financial position is stable and that you can manage all your obligations comfortably.

It is worth shopping around or using a broker, as different lenders apply different stress rates and coverage ratios. The difference between a lender requiring 125% coverage and one requiring 145% can be significant in terms of the maximum amount you can borrow.

Portfolio Landlord Rules and Remortgaging

If you own four or more mortgaged buy-to-let properties, you are classified as a portfolio landlord under rules introduced by the Prudential Regulation Authority. This classification brings additional scrutiny to your remortgage application and requires more detailed information about your entire property portfolio.

When a portfolio landlord applies to remortgage, lenders are required to assess the borrower's entire portfolio, not just the individual property being remortgaged. This means you will need to provide comprehensive information about all your buy-to-let properties, including:

• Property details - Addresses, values and types of all properties in your portfolio
• Mortgage details - Outstanding balances, interest rates, monthly payments and remaining terms for each property
• Rental income - Current rental income for each property along with tenancy details
• A business plan - Some lenders require a written plan outlining your investment strategy and how you manage your portfolio
• Cash flow projections - Evidence of how your portfolio performs financially, including void periods and maintenance costs

The portfolio landlord rules have made the remortgage process more complex and time-consuming for larger landlords. Applications typically take longer to process as lenders need to assess a greater volume of information. Being well-organised and having all your documentation readily available can help speed things up considerably.

Not all lenders offer products to portfolio landlords, which can limit your options. However, specialist buy-to-let lenders and brokers who work with portfolio landlords can help you navigate the additional requirements and find competitive deals. Some lenders have streamlined their portfolio landlord processes and can offer a more efficient service than others.

It is also worth noting that some lenders impose portfolio-level restrictions, such as maximum total borrowing across all properties or minimum portfolio-level rental coverage. Understanding these restrictions before you apply can save time and avoid unnecessary declined applications.

Tax Changes Affecting Landlord Remortgages

Significant tax changes in recent years have had a major impact on buy-to-let profitability and, by extension, on how landlords approach remortgaging. Understanding these changes is essential for making informed decisions about your property investments.

Section 24 mortgage interest relief changes. The most significant tax change for landlords has been the phased restriction of mortgage interest tax relief, known as Section 24. Previously, landlords could deduct their mortgage interest costs from their rental income before calculating their tax liability. Now, mortgage interest is no longer deductible as an expense. Instead, landlords receive a basic rate tax credit of 20% on their mortgage interest costs.

This change has had a particularly significant impact on higher rate taxpayers, who previously benefited from 40% or 45% tax relief on mortgage interest. The reduction to a 20% credit has effectively increased the tax bill for many landlords, reducing their net returns and making affordability calculations tighter.

Stamp duty surcharge. An additional 3% stamp duty surcharge applies to the purchase of additional properties, including buy-to-let investments. While this does not directly affect remortgaging, it is a relevant cost consideration if you are thinking about expanding your portfolio or using equity released through remortgaging to purchase another property.

Capital gains tax. Landlords must pay capital gains tax when they sell a buy-to-let property at a profit. The rates for residential property are higher than for other assets. This is relevant to remortgaging because some landlords choose to remortgage to release equity rather than sell a property, thereby deferring the capital gains tax liability.

These tax changes mean that it is more important than ever for landlords to carefully consider the financial implications of their remortgage decisions. Working with both a mortgage broker and a tax adviser who understand the buy-to-let market can help you optimise your strategy and ensure you are making the most tax-efficient choices.

Some landlords have responded to these tax changes by incorporating their properties into a limited company structure. If you are considering this route, be aware that it involves transferring the property to a new legal entity, which triggers stamp duty and capital gains tax. A remortgage would also be required under the new company structure. Professional advice is essential before making such a significant change.

Releasing Equity Through a Landlord Remortgage

One of the most common reasons landlords remortgage is to release equity from their existing properties. This equity can be used for various purposes, including purchasing additional investment properties, carrying out renovations or consolidating debts.

To release equity, you remortgage for a higher amount than your current outstanding balance. The difference between the old mortgage and the new one is released to you as cash. For example, if your property is worth 300,000 pounds and your existing mortgage balance is 150,000 pounds, you could potentially remortgage up to 225,000 pounds at 75% LTV, releasing 75,000 pounds in equity.

However, releasing equity increases your loan-to-value ratio and your monthly payments, so you need to ensure that the rental income still meets the lender's coverage requirements at the higher borrowing level. The increased interest costs will also affect your overall profitability and tax position.

Using equity to expand your portfolio. Many landlords use released equity as deposits for additional buy-to-let purchases. This strategy allows you to grow your portfolio without needing to save separately for each deposit. However, it also increases your overall debt and exposure to the property market, so careful risk management is essential.

Funding property improvements. Releasing equity to fund renovations or improvements can increase the rental value and capital value of your property. This can be a sensible investment if the increased rent and property value outweigh the additional borrowing costs.

Debt consolidation. Some landlords use equity release to consolidate higher-interest debts such as credit cards or personal loans into their mortgage. While this can reduce your monthly outgoings, be aware that you are securing previously unsecured debt against your property, which increases your risk if you are unable to make payments.

Before releasing equity, carefully consider the impact on your cash flow, tax position and overall investment strategy. A financial adviser who specialises in property investment can help you assess whether equity release is the right move for your circumstances.

Tips for Getting the Best Landlord Remortgage Deal

Securing the most competitive remortgage deal as a landlord requires preparation, research and often specialist advice. Here are some practical steps to help you get the best possible outcome.

Start the process early. Begin looking at remortgage options at least three to six months before your current deal expires. Many lenders allow you to apply up to six months in advance, locking in a rate while your current deal is still running. This gives you time to shop around without the pressure of an imminent rate increase.

Maintain your property well. The condition of your property affects its valuation, which in turn affects your LTV ratio and the rates available to you. Ensuring your property is well-maintained and in good condition before a remortgage valuation can help you achieve a higher valuation and better terms.

Keep good records. Maintain organised records of rental income, tenancy agreements, property expenses and mortgage details for all your properties. This is especially important if you are a portfolio landlord, as lenders will need comprehensive information about your entire portfolio.

Consider your tax status. Your tax status affects the rental coverage ratio required by lenders. If you are close to the boundary between basic and higher rate tax, consider whether there are legitimate steps you can take to optimise your tax position before applying.

Use a specialist broker. Buy-to-let remortgages can be complex, particularly for portfolio landlords or those with unusual properties. A broker who specialises in buy-to-let lending will have access to a wider range of products and will understand the nuances of different lenders' criteria. They are regulated by the Financial Conduct Authority and must act in your best interests.

Compare the total cost. Do not focus solely on the interest rate. Consider arrangement fees, valuation fees, legal costs and any early repayment charges on your existing mortgage. A slightly higher rate with lower fees may work out cheaper overall, particularly if you are borrowing a smaller amount.

Review your portfolio strategy. A remortgage is a good opportunity to review your overall property investment strategy. Consider whether your portfolio is structured efficiently, whether any properties are underperforming and whether your borrowing levels are appropriate for your risk appetite and financial goals.
