Multi-Unit Freehold Block (MUFB) Mortgage
Last updated: 14 October 2026
What is a multi-unit freehold block?
A multi-unit freehold block is often referred to as an MUFB – it’s a property which has been split into two or more flats without creating separate titles for each individual home.
The flats normally have their own separate entrances, and in most cases have their own utilities like gas, electricity and water.
Some landlords are looking to add this type of property to their portfolios because they tend to have a better rental yield. It’s a good proposition for many people.
Am I eligible to get a mortgage on a multi-unit freehold block?
If you’re looking for a Buy to Let mortgage, many lenders are happy to lend on a multi-unit freehold block, but they do have restrictions. If you’re a first-time buyer or a first-time landlord, for example, you’ll find there are fewer lenders available.
Some lenders prefer you to have landlord experience, as multi-unit freeholds do require more management than a regular property. The lenders that accept MUFBs often have restrictions on how many units there can be in the property – as standard, most have a limit of six or less.
Do I need a special mortgage for multi-unit freehold blocks?
You don’t necessarily need a special mortgage, but the majority of high street lenders will not lend on a multi-unit property. You might find that you have to go a bit further afield, to lenders you perhaps haven’t heard of before.
How much deposit will I need for a multi-unit freehold block mortgage?
The majority of lenders will want a 25% deposit for a multi-unit freehold mortgage, but a handful at the moment can look at a 20% deposit.
With more deposit, you will always have more options, so 25% is a good target [information correct at the time of recording in September 2025].
What is the difference between an HMO and an MUFB?
An HMO is a property where the tenants each have their own rooms, but they share facilities such as kitchens, living rooms and even bathrooms or toilets.
Potentially you will need an HMO licence from the local council for this type of property. That will depend on the local authority’s rules, and also how many rooms it has.
An MUFB has self-contained flats, with separate entrances and individual utility supplies. There won’t be any shared facilities apart from perhaps a hallway or porch.

What are the lending criteria for a multi-unit freehold block?
The majority of lenders prefer you to have some landlord experience, but some do offer products to first-time landlords or first-time buyers.
Some lenders will only lend on properties with a maximum of six units, while others have no limit. Those are the main starting points for an MUFB.
What are the usual rates for a multi-unit freehold block mortgage?
The mortgage rates are relatively similar to those for a standard Buy to Let mortgage – for a property just let out to one tenant or family.
It does depend on the specific circumstances. If you’re a first-time landlord, or the property has more than six units, you will probably find that the rates are higher.
What are the benefits of taking out a multi-unit freehold block mortgage?
The main benefit to landlords is the rental yield for that property. It’s usually much higher than if you were to let the whole property to one family on a traditional tenancy agreement. That’s the main attraction.
What are the complexities of taking out a multi-unit freehold block mortgage?
The mortgage process will be relatively similar for a multi-unit freehold block and a traditional Buy to Let property. Complexity can arise if the property has shared facilities – as not many lenders will look at that.
The same goes if there are more than six units in the block. Also, not many lenders offer 80% Loan to Value, so you may find the process a bit harder with a smaller deposit.
Mortgage lenders will also charge a valuation fee for this type of property, so there are higher costs involved when purchasing, and also when remortgaging in the future.
What are the repayment options on a multi-unit freehold block mortgage?
You can have an MUFB mortgage on either repayment or interest only. It just depends on your circumstances and your objectives.
Is it worth investing in a multi-unit freehold property?
The rental yields are usually higher for multi-unit properties, but these do require more time and management from the landlord. You have to weigh that up. The product fees can also be higher, and there are potentially other costs such as valuation etc.
Ultimately, it’s your decision. You need to look at your current circumstances, the scenario in front of you and how you’ll manage this. That will determine if the investment is worthwhile for you.
When we speak to landlords, they do seem to be targeting this type of property now. There are clearly some good investment opportunities here.
How can a mortgage broker help?
The preparation of this is key. If you’re seeing a property, it’s worth speaking to an advisor to help you find the right lender, especially if you’re looking at something unique.
If you’re a first-time landlord or first-time buyer, there aren’t many lenders available – just a handful. You probably will need some support with that so it’s definitely worth getting in touch. Getting an Agreement in Principle in place will always help you in finding the right property.
How Much Can I Borrow on an MUFB Mortgage?
How much you can borrow on an MUFB mortgage is based on the rental income you are receiving, the interest rate and your current tax position. The mortgage lender will stress test the rental income to ensure it can cover the monthly mortgage payments.
If you are a lower rate taxpayer, or are purchasing your HMO property through a limited company you will have a lower stress test calculation to pass. You may also be able to lend more on a 5 year fixed rate compared to a two year fixed or tracker product.
In most cases, as the rental income yield with MUFB’s is strong, affordability is unlikely to be an issue even at higher LTVs.
Are MUFB mortgage rates more expensive?
Lenders that are prepared to lend on an MUFB will charge slightly higher fees and rates for a mortgage. However rental income is usually much higher than a standard buy to let, therefore the higher rate you are charged is usually offset, when it comes to overall profit.
Can I Live in One of the Flats Within a Multi-Unit Freehold Block?
Although rare, there are lenders that can consider this. However your personal circumstances will need to be assessed by the lender to ensure they are happy to lend in with you living in one.
Not all lenders allow this so it is important to select the correct MUFB lenders to approach and clearly present the circumstances to the lender.
Limited Company MUFB
If you’re a property investor who has set up a limited company for your investments, you can purchase an MUFB Mortgage in a limited company.
In many cases, limited company portfolio mortgages offer tax advantages and make managing your properties easier. However, interest rates for limited company buy to let can be more expensive than in your personal name.
Can I Purchase a MUFB Property as a First Time Landlord?
Yes there are lenders that offer MUFB Mortgages for first time landlords. You will need to ensure you have a minimum income of around £25,000 per annum. Most lenders do not allow first time landlords, so make sure you speak with a broker who can guide you to the correct lenders.
