What is a Buy-to-Let Mortgage?

A buy-to-let mortgage is a type of loan designed for those who want to purchase a property to rent out to tenants, rather than live in it themselves. It allows landlords, whether they are a first-time buyer or an experienced investor, to borrow money to buy a property that will generate rental income.

This type of mortgage is available to both individuals and limited companies – but it does come with extra responsibilities, such as landlord obligations, insurance and tax implications.

Buy-to-let mortgages differ from standard residential mortgages in a number of ways. For example, lenders usually require a larger deposit. Interest rates can also be higher, and many buy-to-let mortgages are interest-only. This means that you pay only the interest each month and pay the full loan back at the end of the term.

Many lenders assess affordability differently for buy-let-mortgages. Rather than basing their lending decision on the borrower’s salary, they also consider the potential rental income from the property.

Am I Eligible for a Buy-to-Let Mortgage?

To be eligible for a buy-to-let mortgage, you will need meet a certain set of criteria, including:

Age – most lenders require you to be at least 21 years old
UK residency – you will need to be a UK resident, or have the right to reside in the UK on a permanent basis
Deposit – most lenders usually require a minimum deposit of 25%, but this can vary between 20% and 40%
Income – some lenders may have minimum income requirements, while others may focus on affordability based on potential rental income
Credit score – a good credit score shows your ability to repay the mortgage
Property – lenders will take the worth of your property into consideration. Some lenders may have a minimum and maximum property valuation requirements
Mortgage term – lenders will consider the mortgage term, including the length of time you’ll be paying back the mortgage

What is Rental Income?

Rental income is the money earned from leasing out a property to tenants. This income is usually received on a regular basis, based on the terms outlined in a rental or lease agreement. Typically speaking, lenders expect rental income to be 125% of the monthly repayments on the mortgage.

In addition to the base rent, rental income can include any payments for the use of furniture, hot water, heating, parking, charges for any additional services provided, such as the cleaning of communal areas, and repairs to the property.

For tax purposes, rental income is considered taxable, meaning that it must be reported to tax authorities. How much tax you pay will depend on how much profit you make, and your personal circumstances.

Overall, rental income can be a profitable and stable financial stream when managed effectively.

How to Calculate Rental Income

To calculate your rental income, you will need to start with your gross rental income. This is the total rent you receive from your tenants over a specific period of time – usually a year.

Next, you will need to deduct your allowable expenses to determine your net rental income. Allowable expenses can include letting agent fees, maintenance, repairs, buildings and contents insurance, utility bills, ground rent, council tax and services charges.

Enter your net rental income into our buy-to-let mortgage monthly payment calculator further up the page to work out how much you might be able to borrow.

Interest-only or repayment mortgages: which is best?

For buy-to-let mortgages, you can choose between interest-only or repayment options – but which one is best for you? Below, we take a look at the pros and cons of both to help you decide.

Interest-Only Mortgages

An interest-only mortgage means that you only pay interest on your loan each month – not the principal amount you borrowed.

The advantages

Lower monthly payments – since you’ll be paying just the interest, this means your monthly repayments will be lower.

Flexibility – the lower repayments means that you have the flexibility to free up cash for other investments.

Scope for investment growth – if property prices rise, you could potentially benefit from capital gains while only paying off the interest

The disadvantages

No equity growth – since you aren’t paying off the loan principal, you will not be building equity in the property.

An end of term lump sum – at the end of the mortgage term, you will still owe the full amount of the loan, which can be a big financial strain.

Risk of property market changes – you could end up owing more than the property is worth if the market falls or stagnates.

Repayment Mortgages

A repayment buy-to-let mortgage means that you repay both the interest and a portion of the amount borrowed – similar to a residential mortgage.

The advantages

Builds up equity – each payment made reduces the loan balance, allowing you to build equity in the property.

Less risk at end of the term agreement – the loan is fully paid off by the end of the mortgage term.

A healthier financial future – the amount owed reduces over time, leading to lower debt for a healthier financial future.

The disadvantages

Higher monthly payments – the payments tend to be higher compared to interest-only mortgages due to the fact you’re paying off both the interest and the principal amount.

Less flexibility – you may have less flexibility due to the high repayments, meaning there is less opportunity for other spending.

Slower growth – if your income is tight, having to make larger monthly repayments can make it difficult for you to invest or spend elsewhere.

We have dealt with Ascot Mortgages twice. Once for a mortgage about eleven years ago and recently for life insurance.In both cases we were treated with the utmost respect and professionalism.In the case of the life insurance application, we considered ourselves to be problem customers because of our age and numerous health issues.Richard Johnson, who managed this application couldn't have been more helpful.He worked in our best interest and was dedicated to providing an excellent service.We were kept up to date through all of the stages of the application and when our doctors were very slow in producing medical reports for the insurance company he persisted where others might have given up.The service we had from Richard was pleasant and professional throughout some difficult stages.My wife and I have no hesitation in recommending Ascot Mortgages.
