What is a Buy-to-Let mortgage?

It’s a loan secured on a property that has been purchased with the intention of renting it out. It cannot be used as a residential home.

Buy-to-Let mortgage rates and fees differ from those for a standard residential mortgage, as do lender’s eligibility criteria. This is usually based on the buyer’s circumstances and the determined income generated by the property.

Finding a lender with a product and criteria that match your situation can be quite complex and time-consuming.  So, consulting with a mortgage broker can make the process a little more straightforward.

Understanding Buy-to-Let mortgages

Over time Buy-to-Let mortgages have become popular and are now virtually a standard offering from mainstream lenders. With an experienced mortgage broker to offer the correct advice, it’s never been easier to obtain one.

Buying a property to rent out is now quite an attractive prospect and can pay great dividends in the long term. However, finding the right mortgage can be a challenge, and getting the correct advice is just as important.

Our specialist brokers are trained to provide the best Buy-to-Let mortgage advice, tailored to you.

Yes, it is possible to get a Buy-to-Let mortgage if you don’t own a home. More and more people are becoming Buy-to-Let landlords in this situation.

However, it may be more difficult to get a Buy-to-Let mortgage as a first-time buyer. The lender would be likely to make sure you could afford the mortgage on a residential basis. Whatever your circumstances, you will need to provide information about your current property portfolio as well as income and rental evidence.

It’s also possible to get a Buy-to-Let mortgage under a limited company. Keeping your business and personal finances separate can make sense in many circumstances. Whether you need to use a limited company Buy-to-Let mortgage may depend on your tax status and investment goals.

This is a question we often hear from many landlords, both new and experienced. There are a few options you could consider:

  • Turn your property into an HMO (home of multiple occupation)
    Choosing to rent out your property on a room-by-room basis can significantly increase your lettings income. However, you will need to get the relevant permission from the Local Council.
  • Choose properties with good rental yields
    It might seem like a good idea to buy a property for £300,000 and let it out for £1,200 per month, but it’s worth considering alternatives. Purchasing two properties each worth £150,000 that you can let out for £750 will give you far more return on your investment, as well as splitting your risk of a default on any rent payments.
  • Get the right mortgage advice
    Experienced, professional advice can be worth just as much to you as increasing profits from other methods. A specialist broker can help you to access the most favourable deals and will be invaluable when it comes to the small print. The lowest mortgage rate initially might not be the cheapest in the long run, when considering other fees.
  • Choose an interest-only mortgage
    Paying only the interest amount each month, instead of a repayment amount as well will reduce your monthly costs. However, you will need to make sure you have a way to pay off the mortgage long-term.

As with a personal mortgage, much will depend on how risk-averse you are as a landlord. Obviously, a fixed interest rate means your monthly rate doesn’t change, however, it’s usually higher than a tracker rate. You’ll lose out should interest rates fall, but you will be protected in the case of a rise in the Bank of England base rates.

A tracker mortgage might carry a slightly cheaper interest rate but it does come with the risk of monthly payments increasing in line with any rises in the Bank of England base rate. The attraction is obviously that the rate will drop if the base rate falls as well. Your decision may rest on where you see the pattern of interest rates at the time of you obtaining the mortgage.

Buy-to-Let fixed rate mortgages

This type of mortgage allows you to maintain a fixed rate of interest for a certain period–usually two, three or five years. This means your monthly payments will be predictable throughout this time, and you’ll be protected from any changes in the economy; an unexpected rise in the Bank of England base rate. Conversely, if the Bank of England rate drops, you will miss out on any savings.

Buy-to-Let tracker rate mortgages

The interest rate for this type of mortgage is usually a certain percentage rate (or fraction of a percentage) higher than other various rate indexes. It will be set and then ‘tracked’ for a fixed period–usually two, three or five years. The most common rate to track is the Bank of England base rate, however, some specialist lenders will follow the ‘LIBOR’ (London Inter-Bank Offered Rate).

If the index your mortgage is linked to rises, then so will your interest payments. Similarly, if it drops, then your interest payments will decrease by the same percentage. In the long run, taking this risk could either save you money or cost you more.

You do get some immediate savings, as the rates offered by the lender for a tracker rate are usually a little cheaper than those for a fixed rate. So, if interest rates remain level throughout your term, you will have saved money in comparison to what you would have paid for a fixed rate mortgage.

Yes, this is entirely possible – there is no difference between a mortgage for a Freehold or Leasehold property if an appropriate lease is in place. You should always bear in mind that Leasehold properties will have extra associated costs, such as ground rent and annual service.

The only problem that will set you back regarding your mortgage will be if the remaining period on the leasehold is too short. If there is less than 70 years on the leasehold term, it will negatively impact the property value and therefore the mortgage value and duration. However, it may be possible to negotiate a new or extended lease with the current property owner and/or the landlord.

Lenders will take any regular charges for services and facilities into account when making their affordability calculations and defining how much they will be willing to let you borrow against the potential rental income. It’s important for you to understand what these costs will be and if any future increases will impact your investment’s net income.

The actual owner of the Freehold on the building will also be considered within the mortgage application. In the past, property investors may have had an interest in the Freehold and were also taking out a Leasehold on a property within it, but many lenders are now no longer happy to extend a mortgage if this is the case.

Buy-to-Let mortgage lenders

Buy-to-Let mortgages were once a distinctly specialist area of lending. Therefore, to get a Buy-to-Let mortgage, you would have to approach a specialist lender that only deals with this kind of mortgage. Specialist lenders are still available and they can be great options for landlords – especially when looking at dynamic products, with a spread of criteria and flexibility.

However, thanks to a huge amount of growth in this sector in recent years, more lenders have entered the market. You will even find reasonable Buy-to-Let mortgage products on the high street. This field is competitive, meaning there are many more deals to choose from.

Our team at The Mortgage Centres has a great deal of experience in sourcing the right Buy-to-Let mortgage for a whole range of customers. Please get in touch and we can arrange a free initial consultation.

How do I qualify for a Buy-to-Let mortgage?

The criteria you need to meet will vary from lender to lender. However there are some basics that apply.

Buy-to-Let mortgages are designed for people who typically own their own home and want to purchase or remortgage a residential property for investment purposes. If you are a first-time buyer it’s not impossible to get one, but it will be more difficult.

Typically, you apply for a Buy-to-Let Mortgage as an individual. Although, there are mortgage products available to Limited Companies that have been set up for managing a property lettings business.

After this, there are some key areas that lenders will always consider.

Lenders will define affordability based on the anticipated rent you would be expected to achieve. Lenders will also consider the borrower’s income tax status and fixed mortgage rate period. Each lender’s calculations are different, however, as a guide, the rental income would be expected to be 125% of the mortgage interest, based on a notional rate of 5%. This would build in an element of safety for all concerned in the case of unforeseen interest rates rising.

In a big divergence from residential mortgages, lenders do not always need to see evidence of an independent earned income. Many will consider your application even if the rent from the property is your sole income, but others will want to you to show a minimal income outside of that made from rent of the property – perhaps £25,000 or more.

Lenders will normally expect to see a down payment of around 20-25% of the value of the property, this can change with market trends. If the anticipated rental income is expected to be sufficient, they could be willing to extend a mortgage with an LTV (loan-to-value) ratio of 75-85%.

If you own a number of properties to let, then you will be considered a ‘portfolio landlord’. Lenders may take a favourable view of the overall lending risk. The best way to get an accurate view of how a lender will approach your application is to speak with one of our specialist mortgage advisors.

Can I get a Buy-to-Let mortgage on any property?

Buy-to-Let mortgages are available for most property types, but there are a few that require specialist attention or are just not possible. Here are the few where you might find things differ from a typical Buy-to-Let mortgage:

Leasehold properties

These are generally suitable, but this will depend on the terms of the lease. Typically, lenders will want to see at least 70 years left on the lease, as any period shorter than this will affect the term of the mortgage and often the property value. It could be possible to negotiate a new or extended leasehold with the owner or current landlord.

Mobile homes and houseboats

Lenders tend to exclude houseboats and mobile homes as a mortgageable property, as they are not seen as a suitable loan security.

Flats/apartments

Certain types of apartments and flats might be perceived as a higher risk than others, usually needing attention from a specialist niche lender for a Buy-to-Let mortgage. This can include:

  • Studio flats with restricted living space
  • Ex-local authority flats in larger blocks, and/or with deck access
  • Flats above certain types of property, for example fast food outlets

If you own other properties on the same street or postcode, lender may also take them into account to minimise their exposure.

Before you purchase a property as an investment, you need to understand all the costs that go with property ownership.

Income tax

As you are receiving income from the letting of the property, rent, this must be declared and will be subject to tax. However, as chancellors and budgets come and go, the method by how the tax is calculated continues to change. This caused an increase in demand for ‘Limited Company Buy-to-Lets’, as more landlords want to be tax-efficient.

Capital Gains tax

As you may have to pay tax on the profits if you sell the property in the future, it’s wise to consider how capital gains tax will affect your income and cash flow at the time.

Maintenance

As a property owner, you will have a legal responsibility to the people living in your property. It must be legally habitable and maintained to a certain standard. This obviously comes with a cost, so you should be sure to allow for this in your budget. As we all know problems such as failed boilers or broken roofs can happen out of the blue.

HMOs (houses of multiple occupation) can attract different rules and further costs, so it will pay to do your research into the regulations where you live before going into business as a landlord.

Management

You may wish to manage your property yourself, dealing with all the paperwork, collections and demands of your tenants. However, some prefer to enlist the services of an agent to handle the day-to-day management on your behalf.

This of course comes with another cost–usually a fee of around 10-15% of the rental income. You might also be required to pay administration fees for each new tenancy and the landlord agreement. Again, it’s best to do your research locally.

Corporation tax

Setting up a property investment and letting business as a limited company can offer income tax benefits. You should remember that the profits of your limited company will be subject to corporation tax. A limited company also incurs an initial cost of registering with Companies House and you will also have to pay a certified accountant to file company accounts.

What happens when you want to move your Buy-to-Let mortgage from one lender to another? It’s extremely important to make sure you have the best mortgage deal to suit your individual circumstances, and that the property can provide a sufficient income to accommodate monthly payments and costs.

Whether your mortgage is a fixed or variable rate, it is likely to have an end date to an initial deal period of two, three or five years. After this period, it will revert to the lender’s standard variable rate. As this rate is higher than the initial deal, borrowers will usually try to secure another deal that suits them better.

In this situation, most borrowers will look to other lenders to find a favourable deal on a remortgage product. However at The Mortgage Centres we also consider what your current provider can offer you, via a product transfer.

Overall, mortgage cost will always be the main factor, but there are benefits to remaining with your current provider:

  • No need for additional underwriting
  • No need for recalculations of the permitted loan amount based on rental income
  • No property valuation needed (unless it would be to your advantage and the lender offers it)
  • No solicitors, or their fees, required
  • Far less paperwork for you to handle

How much deposit do I need for a Buy-to-Let mortgage?

The level of deposit each lender will ask for varies according to other conditions around the mortgage.

It’s possible to get one with a 15% deposit, but the criteria will be very stringent, and it could be difficult for many to qualify. It might be more accurate to consider a deposit figure of 25% however it can be higher in some cases.

Anticipated rental value is the most important deciding factor for lenders when considering how much you will be able to borrow. This will usually override their usual minimum deposit criteria, and not in your favour.

For example, if you were looking to purchase a property valued at £300,000, then a 25% deposit would be £75,000. However, if the potential rental income from the property meant they were only willing to lend £210,000, this would take priority over the minimum deposit requirement. Therefore you would need to put down a 30% deposit.

Fortunately, some lenders are now willing to take personal income or a salary into account when considering a mortgage’s affordability. Viewing this as topping up the shortfall from rental income. This is commonly referred to as ‘top-slicing’.

Are Buy-to-Let mortgages more expensive?

Typically, a Buy-to-Let Mortgage is more expensive than a standard residential mortgage. Looking at the costs involved, you would be dealing with the following:

  • Set-up and valuation fees
  • Arrangement or completion fees
  • Interest rates

Different lender’s completion fees vary greatly and may be up to 3% of the loan value in some cases, reflecting the commercial nature of the property.

Lenders set their interest rates according to the commercial proposition, the market at the time and their higher level of perceived risk. It will not be a huge difference, but the rate will be a little higher than you would expect for a residential mortgage.

Most borrowers opt for an interest-only mortgage for their Buy-to-Let property, the main reason being down to tax efficiency.

With an interest-only mortgage, the loan amount is constant and does not decrease with time. This also means that over the course of the loan, you will end up paying more interest in total. This can work well for borrowers with a certain tax position but might not be suitable for everybody.

Are Buy-to-Let Mortgages worth it?

Buy-to-Let Mortgages are a great way to generate income, however they are not without risks. It is important you consider both positives and negatives to see if you are making the right choice for your circumstances.

Positives Potential negatives
  • Tax Benefits – various costs can be claimed back when submitting your Self-Assessment Tax Return to HMRC. Including mortgage repayments, repair fees and council tax payments.
  • Increased Stamp Duty – You will have to pay an additional 3% on top of what you would have to pay on a standard residential mortgage.
  • Financial Gain – It goes without saying that a successful Buy-to-Let business can benefit you financially, especially in the long term as house prices increase with time.
  • Market Uncertainty – Currently at the time of writing (September 2023) the rental market is very strong, however you need to be prepared if this is no longer the case and finding tenants may be increasingly difficult.
  • Strong Rental Market – If the market is strong and demand for rental properties is high, you can capitalise on this.
  • Rental Risks – there is always the fear of tenants failing to pay rent, void periods, or damage to your property. Obviously, there are various types of insurance you can take out to mitigate the risks to your finances.

Porting depends on the lender criteria at the time. Most lenders will allow you to port a deal should you meet this criteria.

There are specialist lenders in the market who are prepared to lend to those potential investors with a bad credit record. Adverse credit events that will need to be considered are:

It’s important to remember that the amounts involved, the severity of the event, and the amount of time that has passed, as well as the applicant’s current financial situation, will affect the view taken by the lender when they consider the mortgage application.

It’s absolutely possible, but how difficult the process will be will depend largely on their residential and employment status. If you’re a resident in the UK, have the right to live here permanently, are here on other forms of Visa such as Tier 2, then there should be minimal issues. Your employment status and length of time spent in the UK may also have a bearing.

However, things will be a lot more difficult if you are a foreign national no longer living in the UK. But there are specialist lenders available out there. The product options may be rather limited and you might background checks to be a little more thorough than usual, as there is an increased risk to the lender.

Most mainstream lenders will not entertain the additional perceived risk involved with extending a mortgage on a UK property to individuals based outside of the country. And those that will undertake this plan will apply for tighter criteria for underwriting. Perhaps if the applicant is working for a global employer, this will help your case, but it is no guarantee. What is certain is that a lender will demand a higher deposit–perhaps in the region of 25-30% or more.

Buy-to-Let mortgages for expats is a very specialist area of mortgage underwriting, and lenders in this sector typically use their own very individual criteria. For this reason, it’s recommended that you discuss your situation with an experienced mortgage broker with knowledge in this field.

When looking for a Buy-to-Let investment opportunity, there is no difference between buying a new-build or an existing property. As usual, the lender will state a minimum deposit required and the anticipated rental income will be a key factor in their calculation.

It’s true that when purchasing a Buy-to-Let property, you will be likely to pay more Stamp Duty. The government introduced new Stamp Duty rates in 2016, so anyone buying a second or additional property will have to pay an extra surcharge of 3% on top of the current rates

There is no official limit on the amount of Buy-to-Let properties you can own. There are a number of landlords who have an extended portfolio of properties that they manage in the course of their property business.

However, some lenders will impose their own limits on the size of the portfolio you can hold with them.

Most mainstream lenders will usually be content with a maximum of 10 properties, with at most 4 under mortgage. They may also impose a cap on the total level of borrowing between £2M-5M. However, this all depends on the lender.

If you have three or more investment properties, you are normally viewed as a ‘portfolio landlord’ so lenders will be more thorough with their underwriting criteria. They will often carry out a full analysis of your portfolio and may require your income tax assessments. They may also need things like copies of your tenancy agreements.

Typical Buy-to-Let mortgages that are taken out on properties solely for investment purposes, are not regulated by the FCA (Financial Conduct Authority).

A property will become regulated when the property is occupied by a family member or will be in the future. This usually refers to immediate family – siblings, parents, grandparents, or children.

Extended family members are not classed in the same way so a conventional Buy-to-Let mortgage would be suitable.

There are exceptions to this rule – if your family member was living in less than 40% of the property. Typically applying in the case of an HMO where there are multiple non-related occupants also residing. As ever, you should consult with an expert before making any final decisions.
