converting property into flats in the UKRenovating and converting houses into multiple dwellings is increasing rapidly in popularity across the UK, but more specifically in busy city and urban areas with a high concentration of young and wealthy professionals.

Converting a house into flats in London, for example, has seen a notable and marked increase in recent years thanks to a large influx of workers into the city with many now falling under this type of tenancy.

The benefits are clear for landlords focused on yields and rental income as well as capital appreciation and it’s changing our cities and the way we live in them.

Step by step guide on turning your house into flats

Do your research

An essential part of the process is researching the area you’re looking to covert in and what the rental market looks like.

Some of the questions you’ll need to ask yourself are:

  • Are flats in demand in my area?
  • Is my area close to or within a busy commuter area?
  • What does the average rental income look like for similar properties in my area?

As this is going to be a major investment for you, it should be researched and considered as such and using property websites like RightMove and Zoopla can help you get a good picture of what demand looks like where you’re looking to buy.

How to finance the conversion

At Hank Zarihs Associates we offer a wide range of services, but the best advice we can give is to get in touch with an experienced bridging loan broker who can speak to you about your personal circumstances.

Regardless of whether you’re an existing landlord, intending to become a landlord, or just an investor it’s important to know what’s available.

Finance, fast bridging loans, mortgages and other services will differ from customer to customer, and it’s important for you to understand what’s available to you before committing to your project.

Planning permission

These requirements will depend on the area you’re looking to convert your property in. Strictly speaking there are some circumstances where you may not need planning permission, however, it’s usually advisable to contact the local planning department before you start any work and seek their advice.

Converting a house into flats without planning is possible, but for the sake of risk aversion it’s worth scoping out your local planning situation first.

Different areas may have different expectations or different interpretations of planning legislation and there’s the possibility that your property may be located on conservation land which will have big implications if that’s the case.

Taxes

Your tax implications will depend on whether you plan to rent or sell your property once the conversion is completed.

Should you decide to sell there could be capital gains tax to consider, and if you decide to rent then there are certain income taxes or self-assessment obligations that may become relevant.

This is also likely to depend on whether you operate as a Limited company, a sole trader or as a private individual. If you have an accountant or tax advisor it’s certainly worth seeking their advice as you may also be able to write off some of your costs, such as the interest on your mortgage as well as maintenance costs.

Legal and other costs

Whilst converting houses into flats is a very popular choice there are also legal considerations.

You’ll need a solicitor to act for you to deal with the initial transaction in purchasing the property and it’s worth seeking their advice at the point of sale if they can spot any potential future problems.

You may also need to get an estate agent involved in the purchase of the property and, should you want to sell, the process of putting your flats on the market. If you’re looking to rent your flats then you may also need a lettings agent to potentially market and manage your properties.

There are also likely to be building regulations as well as health and safety laws to adhere to, such as providing fire escapes, fire alarms, separate electricity supplies, and so on. This is likely to mean you’ll need some kind of legal advice to ensure you’re on the right side of the law as well as a building company that incorporate these into the design.

There are other things that you may need to consider a little further down the line such as insurance and what type you’ll need whilst converting and once you’ve completed. If you’re intending to rent long-term with tenants, then this will likely require different insurance.

Seeking planning permission, should you require it, also brings additional costs too. Each project will be different in its scope and requirements so it’s always worth having a reliable solicitor to hand for advice.

What is your exit plan? Sell or rent?

It’s an important consideration as this will impact your tax liabilities and property refurbishment finance requirements when converting property into flats.

There are benefits to both, of course, with selling meaning a quick profit and a cash return as well as shorter financing terms. When you’re looking to buy a property to convert there’s financial decisions that can influence your decision.

Renting on the other hand allows you a longer term income and the benefit of capital appreciation as house prices rise and rental demand increases your yield. Tenancy and occupancy rates can vary depending on area and the economy, but overall if your research is sound this shouldn’t be a huge worry.

All in all, it’s worth giving this some consideration before you complete your purchase so that you’re aware of all the other possible implications.

Can I convert a house into flats without planning?

Technically, yes you can, since October 2010 the conversion of a single dwelling into two separate units was deemed ‘Permitted development’ for between 3 and 6 people.

That being said, it’s strongly advised that you contact your local council or planning beforehand to seek their advice as the last thing you want is retrospective enforcement which can cost a lot of money.

Different areas will have different requirements, and there’s potential that there’s new requirements, so it’s worth checking first.

Can I convert a terraced house into 2 flats?

The short answer is yes you can. You’ll need to do your research and think about the layout and the optimal use of your space, but there’s nothing stopping you from converting a terraced house into flats.

Dividing a house into two dwellings is the most common outcome when converting terraced houses due to available floor space, but there are plenty of options within that. Converting a terraced house into 2 flats often proves to be the most popular option.

As with the other conversions, speak to a solicitor, a financing expert and your local planning department before you complete your purchase.

Can I convert a Victorian house into flats?

Again, the answer is fairly simple: yes, you can.

Converting a house into 3 flats is often an option for Victorian houses due to the added space and, specifically, converting a Victorian house into flats is a hugely popular option in city suburbs.

If you plan ahead, think about how to utilise the floor space, research your market and do your due diligence then most properties are suitable for conversion.

Will converting my house into flats affect my mortgage?

landlord needing mortgage to finance houseThis will depend on your current mortgage and the terms you agreed to, however, in most cases it’s fair to say that it will, and you’ll need to speak to your mortgage provider beforehand to understand the implications.

Converting a house into flats mortgage options can sometimes seem a little daunting with many different options such as the potential to remortgage or apply for an extension, so it’s worth seeking advice from an agent as there is quite a large menu of potential choices.

With most property developments finance or conversions it’s usually worth speaking to a specialist finance company with good experience of the commercial market that can provide you with specific advice as residential mortgages are rarely appropriate for these types of projects.

At Hank Zarihs Associates we specialise in development and investment funding. We have the experience and expertise required to present your project in a format which will satisfy the lending institutions credit committees.

Do I need to soundproof each flat?

You won’t need to specifically soundproof the flats individually, but it is your responsibility to ensure that your occupants have reasonable enjoyment of the property, and this will include steps to ensure that noise from adjoining properties is kept to a reasonable minimum.

Converting house into flats with soundproofing is a frequently asked question in that some worry they have to completely eradicate noise pollution, but this isn’t the case.

When you hire a builder or construction company this is something you can discuss in greater detail about the design and how to ensure that noise is kept to a reasonable minimum, and this may consist of insulation, for example.

This isn’t likely to increase your costs significantly and is something that is contained within existing building regulations, so if you’re hiring an experienced company that has done these types of conversions before they should be able to provide advice on things like noise reduction, fire doors, and other responsibilities.

Frequently Asked Questions

You may have heard about bridging loans in the context of property investment or moving house, but what exactly are they? Basically, bridging finance is a type of short-term loan that allows a buyer to purchase a property before their existing home or investment property is sold. As the name suggests, it ‘bridges’ the funding gap in the lag between purchase and sale – offering rapid access to the necessary purchase funds for a brief period of time.

Borrowers can access from £5,000 to £250 million, depending on applicant status, the value of the property and other lender criteria. Higher lending amounts are typically reserved for borrowers who can put up several properties as security. Quotes are provided on a Loan to Value (LTV) of 65%-80% in most situations.

Bridging loans can be used in a number of situations. For example:

  1. When people are moving home in a chain, with a gap between completion dates (e.g. needing to pay for the new property before receiving funds on the completed old property).
  2. When property investors or private buyers renovate a home and want a rapid sell-on.
  3. When an individual is looking to buy a property at an auction.
  4. When property investors and developers are looking to pay a tax bill
  5. When buyers want to secure finance against an uninhabitable property.

This type of finance can be used by homeowners, landlords and property developers alike.

The bridging finance market has grown rapidly, with a number of small and focused lenders now on the market, catering for specialist property finance needs. The market has changed because large high-street lenders have become less willing (and sometimes less able) to lend ever since the financial crisis of 2008.

As to whether a bridging loan for property development, auction purchase or private home buying is a good idea, it depends on a variety of factors. Bridging loan requirements vary by lender, but each will have certain common features that need to be considered.

The most notable feature of this type of finance is that the interest rate is likely to be high. At the same time, there are typically high administration fees applied to the loan. Because of this, it is essential to proceed very carefully and with a full view of the facts. Borrowers have been burned by this type of loan in the past, in instances where transactions have fallen through, or where lenders have turned out to be unscrupulous and untrustworthy.

Benefits of instant bridging loans

1. Rapid access to money
2. Ability to borrow large sums – often up to £250 million depending on applicant status
3. Options for flexible borrowing.

Possible downsides of bridging loans:

1. Failure to understand the unique features of these loans can result in financial risk
2. Bridging finance is secured against your property; meaning it can be sold if you can’t meet the repayment terms
3. A costly option with fees and higher interest

Bridging finance interest rates will vary by lender. However, interest costs of 1.5% a month are not unusual, which can equate to an annual percentage rate of 18%.

Bridging loans may have fixed or variable interest rate features. Fixed interest rates are ideal for customers who want stability, as they offer the same amount of interest for the duration of the term. The rate is pre-agreed, but there may be a premium for this security.

The other choice is to have a variable rate bridging loan which can change with the base rate. However, you can save money if the base rate decreases. Borrowers who are less concerned about security sometimes prefer the variable rate option if they believe that the financial markets will travel in their favour. Knowledge and market insight is required here, along with a thorough understanding of personal risk tolerance. If interest rates appear to be rising, most customers will choose the fixed interest rate to lock it in and avoid further increases in the event of a base rate rise.

Bridging loan periods tend to be for several months and there are usually different options for paying the interest portion.

Monthly repayments

The customer repays the interest every month as a separate payment, rather than adding it to the outstanding balance

Rolled-up bridging finance deals

The compound interest is calculated monthly but added to the outstanding loan balance and paid together when repayment is due.

Retained interest

The monthly interest payment due is covered up to a predefined date so that the full sum is only repaid when monies are due.

As well as interest payments, there will be an arrangement fee for the set-up of the bridging loan, which is usually around 1-2%. A repayment fee for exit paperwork may also apply, along with valuation fees for the cost of the surveyor.

Remember, this type of finance is designed to be short-term. As soon as it extends beyond the agreed interim or bridging period, penalties can rapidly stack up. Typically, bridging finance is available for 1 – 18 months.

Yes, there are two broad types: closed bridging finance and open bridging finance.

With closed bridging finance you will tell the lender how you will repay the loan – with what funds and when. These loans usually complete within a few months and the clear exit plan is required as a lending condition.

Open bridge finance won’t usually need this type of exit plan, and it is typically the loan of choice when funds are needed urgently to complete a property transaction. No detailed plan is needed to explain how the debt will be settled, and the finance tends to be offered for up to a year. Of course, it’s important to note that interest will keep being applied throughout this period.

There are also first charge bridging loans and second charge bridging loans.

If you have a loan against a property which is already mortgaged, you’d take out a second charge loan. An example of this would be if you were planning to finance a property extension to improve the property. The categorisation tells the lenders who will have legal priority for repayment if the loan was unable to be paid off at the term-end.

First charge loans apply if the new loan is the first secured on the property.

Bridging loan requirements will depend on the lender. Often, lenders will require that:

Customers must also take out their property mortgage with them too, providing the bridge finance as an interim measure before the standard mortgage comes into play.

Property is put forward as security against the loan. Some lenders expect applicants to have more than one property in order to be eligible for their bridging finance products, but this will depend on the lender and the size of the loan.

Applicants show proof of income – although, interestingly, as loan interest isn’t repaid monthly, some lenders do not request this.

The applicant shows evidence of their property investment track record if they are planning to develop their purchased property.

The applicant can show a business plan if they are using the bridging loan for commercial purposes.

Development loans are another type of short-term property development loan. They are repaid in stages and calculated on the gross value of the development. Personal loans are another option, as are remortgages when timescales are more flexible and a long-term loan is desirable.

Use a bridge loan calculator
Ask for your lender to provide a tailored bridge finance example or illustration around your particular borrowing needs.
Think carefully about the type of bridging loan that you need – whether open bridge finance or closed bridge finance.
Know whether the loan is a first or second charge type.
Clarify whether the interest rate is fixed or variable.
Review products from several lenders.
Be clear on your security.
Read the small print!

Bridging loans are offered by banks, building societies, specialist lenders and brokers. They aren’t widely advertised and usually require a direct application by the customer to find out the product features and offers.

Once you have made an application, a decision will usually be made within 24 hours. The funds then will take around two weeks to be issued, including time for checks to be carried out, the valuation and the actual transfer.
