It’s certainly possible to get a mortgage to buy a flat and an increasing number of people in the UK are taking advantage of this. There are, however, extra considerations to take into account with this property type and this can make things less straightforward than mortgages for houses.

That’s why we’ve put together this comprehensive guide to mortgages for flats. In it, you’ll learn what makes flat mortgages different to house finance, how to get a mortgage on a flat, and where to find a mortgage broker who specialises in this property type.

Can I get a mortgage on a flat or an apartment?

Yes, as long as you pass the mortgage lender’s criteria for a mortgage on a flat or an apartment, there’s no reason why not.

Eligibility criteria for flat mortgages is no different from that of any other residential property loan: you’ll need to convince the mortgage lender that you have sufficient income to meet monthly repayments, meet their criteria in terms of your credit history, employment and age profile, and the flat you intend to purchase must be of a construction type that they accept.

There are a few extra things to take into consideration with mortgages on flats, though. Firstly, your choice of mortgage lenders might be fewer depending on the extra type of property the flat is. Many of them, such as high rises and those that aren’t made from bricks and mortar, fall into the ‘non-standard category which often means a specialist lender is needed to get the best rates.

Another thing to think about is whether the flat or apartment is freehold or leasehold. Most of these properties are mortgaged on a leasehold basis, so freehold flat mortgages can be more difficult to get.

The good news about flat mortgages is that professional advice is available for them. There are mortgage brokers whose forte is flat mortgages both standard and complex – some specialise in non-standard property types while others arrange leasehold flat mortgages every day.

If you make an enquiry with us, our free broker-matching service will pair you up with the ideal advisor for you.

Getting a mortgage on a freehold flat

Getting a mortgage on a freehold flat can be difficult and fewer providers are willing to accept them, but that isn’t to say it’s impossible.

If you were to approach a mortgage lender at random from a freehold flat mortgage, there’s a chance you might be offered less favourable rates or be turned away altogether. What you’d often need in this situation is a broker who specialises in arranging freehold flat mortgages, as they know exactly which mortgage providers have a high enough appetite for risk to lend under these circumstances.

Why freehold flats are more difficult to get a mortgage on

Leasehold means that you have a contract or ‘lease’ that permits you to occupy the property for a specified number of years (the ‘lease’) on behalf of a freeholder, which is usually a company. In a freehold situation, there is no external body with responsibility for the property: this falls to the owner.

Some lenders are wary of this type of setup as it can lead to a lack of accountability for repairs and other costs, which could reduce the property’s value. Without a sole entity with responsibility for these costs, it’s easy to see how a block of flats could fall into disrepair: even if there is a lease setting out the rules, none of the parties is obliged to pay for them.

The possibility of disputes between neighbours is increased because, for example, one person’s floor is another person’s ceiling. If there’s a leak then both parties could expect the other to be liable.

Ground rent and maintenance

In a leasehold arrangement, you’ll need to pay the company an annual fee called ‘ground rent’ to undertake maintenance and repairs of communal areas. The freeholder’s responsibility in that contract is to ensure the upkeep of the property to a standard outlined within the lease.

In a freehold arrangement, however, the freeholder is the ultimate owner of the property itself, so you will take on that role when you purchase the freehold along with the property. You won’t need to pay a maintenance fee, but you will need to ensure the flat is maintained as per the lease.

One exception to this is in Scotland because leasehold properties are virtually nonexistent north of the border. Most flats are on arrangements similar to a freehold. Many lenders who do not lend on freehold flats in England and Wales will offer mortgages in Scotland for these properties.

Getting a mortgage on a share of freehold flat

Some flats are sold on a ‘share of freehold’ basis. In this case the owners of a number of flats own the freehold jointly for the entire building (often a converted house), and are thus responsible for carrying out repairs and maintenance, and for setting up a maintenance company should they decide to do so. Share of freehold can be split between as few as two flats, with a 50-50 share for each owner, or up to four owners.

Fortunately, from a lender’s perspective Share of Freehold arrangement is treated the same way as a leasehold property and the freehold flat mortgage problems that make lenders nervous don’t apply, because the ‘company’ in which the flat owners hold shares legally owns the lease and must abide by the obligations it sets out. For this reason, it’s usually no harder to mortgage a shared freehold flat than a leasehold flat, but speaking to a mortgage broker beforehand is still recommended as this can help you get the best rates.

Length of lease

When buying a leasehold or share of freehold flat, the number of years remaining on the lease will have an impact on the flat’s resale value and therefore will affect the number of lenders that will consider your mortgage application.

Each lender sets a minimum length of lease that they will consider, which is usually between 90 and 70 years, and rates will be less favourable the shorter the remaining term. Few will lend at all with a lease of 70 years, and hardly any will lend if the remaining time on the lease is 60 years or less.

If you have your heart set on a flat with a short lease, you may want to find out if the seller will extend the lease or negotiate a lower price in exchange for doing this yourself before settling on a mortgage.

How the type of flat you’re buying can affect your mortgage options

Another aspect of getting a mortgage on a flat that can complicate matters is the fact that there are so many different kinds of flats. The type and age of the building, where it’s situated and even the number of bedrooms can directly affect lenders’ generosity.

Flats above shops and other commercial premises

Many flats are located above commercial premises, but it can be harder to get a mortgage on this type of property. Lenders have different policies on which premises they’ll consider (some accept flats above certain retail outlets but not above bars or restaurants for example), or whether they accept them at all: see our guide to mortgages for flats above shops.

New-build flats

Getting a mortgage on a new build flat can present some challenges for a variety of reasons. First, it’s harder for lenders to do an accurate valuation on any new build, so many want bigger deposits to protect against a possible drop in value after the sale. For a new build flat, a deposit of 30% or more is not unusual. Added to this, many new build flats are in high rise blocks, which will exclude some lenders leading to potentially higher rates.

However, new builds tend to have more incentives available to buyers such as the Help to Buy scheme for example, and in some cases developers may offer to chip in to cover some of the higher costs such as part of the deposit.

New-build buy-to-let flats can be even trickier to come by: some lenders exclude new builds for investment mortgages, and those that do lend on buy to let new builds tend to impose strict criteria and large deposits of 25% or more.

Conversion flats

In many cases getting a mortgage for a conversion flat should not pose any specific problems, but if it’s a recent conversion, lenders are likely to view it in the same category as a new build, and will want to see evidence that the works have been carried out within regulations and to a satisfactory standard.

Each lender will have its own set of standards, so it helps to work with an expert broker who can identify the most suitable providers.

Flats in high rises

High rise flats can be tricky to mortgage, and it’s worth being aware that many lenders consider flats on a 5th floor or higher to be ‘high rise’.

Each lender will have its own attitudes towards high rise flats and any offer they make will be subject to survey. So if you’re buying a modern apartment in a smart complex, you’ll find it easier to get a mortgage than if it were in a grimy old block where resale value is likely to be an issue. It can also be difficult to get a mortgage on a concrete flat, which some lenders view as ‘non standard construction’.

As a general rule of thumb, most lenders will require there to be a lift in the block if there are 5 or more floors.

Non-standard construction flats

Another factor that can affect your chances of getting a mortgage for a flat is the type of block or building it’s in or even the materials it’s made of. This can affect whether a mortgage is offered or not, for example properties made out of wood or timber, high rise flats (as above), concrete blocks, corrugated iron constructions or having asbestos present.

All lenders are different in what they’ll accept, so having one or more of these issues shouldn’t rule you out. For more information, see our guide to non-standard property.

Small flats

Some lenders impose minimum size limits on properties they will mortgage, and this will often apply for those looking to take out a mortgage on a 1-bedroom flat or bedsit/studio.

This is ultimately due to legal definitions of what constitutes a living space: anything below 12 sq m is in breach of the 2004 Housing Act, and of those lenders that do accept studio flats, virtually all specify a minimum flat size for mortgage of 30 sq m.

Flats in London

Flats and apartments in major cities especially London can reach very high values compared with elsewhere with prices that can run into the millions, so a lender that caps its maximum loan size for flats relatively low won’t be much use if you’re purchasing a three-bed maisonette in a trendy London suburb, for example.

Another consideration if you’re taking out a London flat mortgage is that the capital’s flats also tend to be smaller, so if you’re purchasing a one-bed you might fall foul of the restrictions that some lenders place on ‘cosier’ properties.

Holiday flats

Provided you meet lender criteria it should be possible to get a mortgage for a holiday flat, but these will be different depending on whether you intend to rent out the holiday flat or reserve it solely for your own and your family’s use. If it’s being used for rental, you’ll need a BTL mortgage, otherwise it will usually be classed as a second home. Some lenders may offer a more flexible holiday flats mortgage: speak to an expert for advice if you’re interested in this type of product.

How much deposit will I need for a mortgage on a flat?

Most lenders offer slightly lower loan-to-value (LTV) ratios for flats, for example they may go up to 90% or even higher on houses but only 85% on flats, meaning you’d need to pay at least a 15% deposit for a flat versus 10% on a house.

How much can I borrow?

This will depend on your income (not only how much you earn but the type of income), the size of deposit you are able to put down, and a host of other factors relating to the state of the market. Currently, most lenders cap lending at 4.5 x your salary/combined salary, some will go up to 5, and a few as high as 6 x in exceptional circumstances.

All lenders are different and some will offer more generous deals than others, which is why it’s important to shop around and work with a whole-of-market broker to home in on the best ones. All of the mortage advisors we work with have access to the whole market and there are brokers in our network who specialise in arranging mortgages on apartments and flats.

Lenders who offer mortgages for flats and apartments

The vast majority of high street lenders offer mortgages for flats, but as outlined above, their attitudes towards types, locations and sizes of flats, new builds, lease lengths and other features vary, so depending on your circumstances, this can result in having a slightly smaller pool of lenders overall when compared with mortgaging a house.

Furthermore, most lenders do not offer mortgages on freehold flats: well-known names such as Lloyds, Yorkshire Bank, and Halifax won’t even consider these agreements at present.

There are, however, a few that will consider it: Royal Bank of Scotland and Natwest don’t usually accept freehold flats, but they may make an offer if the loan is less than 95% of the valuation and there is an acceptable maintenance agreement in place.

Similarly, Nationwide won’t lend on most freehold flats, but will make an exception in certain circumstances. Speak to an expert to get access to the most up-to-date information on mortgage lenders for freehold flats.

Can I get a flat mortgage with bad credit?

Yes. Credit issues such as low credit score, IVAs, late payments, defaults and bankruptcy will contribute to raising your overall risk profile, and are likely to reduce the number of interested lenders. Fortunately, there are plenty that will still accept borrowers in most circumstances, although you may be offered higher rates.

If you’re worried that your credit issues could make it hard for you to secure a mortgage to buy a flat, take a look at our section on getting a mortgage with bad credit, and don’t hesitate to make an enquiry if you’d like us to refer you to an advisor with experience of successfully arranging mortgages for clients with adverse credit.

Can I get a mortgage for a flat as a second home?

Yes. There are numerous lenders offering mortgages on flats as second homes. You will be subject to the same financial assessments as with any mortgage, and your existing mortgage commitments will also be taken into account and the rates on any second home mortgage are likely to be higher.

Can I get a mortgage on a retirement flat?

Yes. If you’re planning on purchasing a purpose-built retirement flat, you will usually need to find a specialist lender to arrange a retirement flat mortgage, as these products are relatively niche and not usually sold directly to the public: get in touch with us if you’d like to be referred to an advisor with experience in this area.

If, however, you are looking for a retirement-friendly mortgage for a standard flat, you can usually arrange a lifetime mortgage for flats provided it has sufficient time remaining on the lease according to your lender’s policy, but speak to an expert about this before making a decision, as professional advice is recommended.

Can I get a mortgage for a granny flat?

Yes. A ‘granny flat’ or annexe is a specific class of property defined as a ‘secondary dwelling’ attached to an existing property. The main dwelling is often, though not always, owned by a different generation of the same family. Getting a mortgage for a granny flat is a complicated process due to the number of parties involved and often due to the age of the older resident(s), but it’s certainly doable.

Another issue is the granny flat’s intended use: if the ‘annexe’ is deemed to be completely self sufficient with its own kitchen facilities for example, it may be necessary to take out a buy-to-let mortgage, as it could in theory be rented out.

For this type of arrangement, borrowers need to seek a mortgage for a house with a self-contained flat. We strongly recommend speaking to an expert advisor for the best solution.

How do I get a mortgage on a buy-to-let flat?

See our guide to buy-to-let mortgages for in-depth information on this. Mortgage options are plentiful in this area with most major lenders offering buy-to-let (BTL) mortgages on flats, subject to the usual caveats of BTL lending, which generally means higher rates, lower LTV ratios and most are offered on an interest-only basis. In the case of buy to let mortgages for new build flats, criteria will be even stricter.
