Mortgages on a Maisonette Property

A maisonette can be an attractive alternative to a flat or house, offering a more “home-like” layout—often over two floors and sometimes with its own entrance. For mortgage purposes, however, maisonettes are not treated exactly the same as standard houses. Lenders tend to look closely at the legal structure of the property and the risks that can affect valuation, resale, and affordability.

This guide explains how mortgages on maisonettes work in the UK and the main factors that commonly influence lender decisions.

Can you get a mortgage on a maisonette?

In most cases, yes. Maisonettes can be financed with a residential mortgage, and in some situations they may also be considered for buy-to-let lending.

That said, the mortgage market for maisonettes can feel narrower than for more straightforward property types. The reason is that maisonettes often come with extra variables—particularly around whether the property is freehold, leasehold, or part of a shared freehold arrangement, and whether the building has any mixed-use elements.

The three main types of maisonette ownership

1) Freehold maisonettes

A freehold maisonette means you own the property and the land it sits on. This can be appealing because there is no lease term running down over time.

However, “freehold” doesn’t always mean “no shared responsibilities”. Some freehold maisonettes still involve shared areas or obligations—such as maintenance of external parts, driveways, garages, or access routes.

What lenders may consider:

• Whether there are shared external areas
• How maintenance responsibilities are set out
• Whether ongoing costs could affect affordability

2) Leasehold maisonettes

Most maisonettes (outside Scotland) are sold as leasehold. In this structure, you buy the right to live in the property for a set period, while the freeholder owns the land.

Leasehold maisonettes typically involve:

• Ground rent (where applicable)
• Service charges for maintaining shared parts of the building or estate

Lenders pay particular attention to lease details because they can affect both affordability and long-term value.

Lease length matters most: As the remaining lease term reduces, fewer lenders may be willing to lend, and mortgage terms can become less flexible.

What to check before applying:

• Current remaining lease length
• Level and history of service charges
• Whether the property is a new build (service charges can be higher in the early years)

3) Share of the freehold maisonettes

A “share of the freehold” arrangement usually means the leaseholders collectively own the freehold through a company, with each owner holding a share.

This can give owners more influence over building decisions and shared costs. But it can also add complexity for lenders—especially where there are multiple owners, differing responsibilities, or unclear documentation.

What lenders may consider:

• How the freehold is managed day to day
• Whether responsibilities are clearly documented
• How costs are allocated between owners

What lenders look at when assessing a maisonette mortgage

While the fundamentals of mortgage affordability and property value still apply, lenders often focus on a few maisonette-specific areas.

Affordability and ongoing costs

For leasehold (and some freehold) maisonettes, affordability is not just about the monthly mortgage payment. Lenders may take into account expected outgoings such as:

• Service charges
• Ground rent (where applicable)
• Maintenance responsibilities for shared areas

Property layout and marketability

Maisonettes often span multiple floors and may have a private entrance. Lenders may consider how this affects valuation and how easily the property can be sold in the future.

Lease details (if leasehold)

For leasehold maisonettes, lenders typically assess:

• Remaining lease term
• The lease’s structure and terms
• Whether costs are likely to be manageable

Location and building configuration

Some buildings include commercial premises. Lenders may apply additional scrutiny where the maisonette is part of a mixed-use block.

Construction type and structural risk

Lenders may treat non-standard construction differently because it can affect valuation, insurance availability, and resale.

Lease length: why it can limit lender options

Lease length is one of the biggest practical issues for leasehold maisonettes. As a lease shortens, the perceived risk increases and the range of lenders willing to lend can reduce.

In broad terms, longer leases are generally easier to mortgage than shorter ones. Exact minimums vary by lender and by the mortgage product being considered.

Practical takeaway: If you’re considering a leasehold maisonette, review the remaining term early—before you commit to the purchase—so you can understand whether mortgage options are likely to be available.

How service charges can affect borrowing

For leasehold maisonettes, service charges can fluctuate depending on building maintenance needs. If the building requires major works—such as roof repairs, external redecorations, or upgrades—service charges can rise.

Because of this, lenders may want to see that the ongoing costs are:

• Clearly defined in the lease
• Reasonable and not unexpectedly high
• Supported by available information (such as recent statements)

Maisonettes above shops or commercial premises

A maisonette above a shop can be mortgageable, but it may influence lender appetite because mixed-use properties can carry additional risks.

Lenders may look for evidence that the residential part is properly separated from the commercial element.

Common factors lenders may consider:

• Whether there are separate entrances and utilities
• Whether residential and commercial areas are legally separated
• Potential noise, access, and disruption considerations
• Structural and compliance factors for the building as a whole

Shared freehold: what lenders may want to see

With share of freehold arrangements, lenders often focus on clarity—particularly around how responsibilities are handled.

In practice, lenders may look for:

• Clear documentation of decision-making and responsibilities
• Evidence that the building is managed appropriately
• A structure that reduces uncertainty for future owners

If the paperwork is unclear or responsibilities are disputed, it can create friction in underwriting.

Construction type: why non-standard builds can be harder

Most lenders prefer standard construction because it’s easier to value, insure, and resell. Where a maisonette is built using non-standard methods, lenders may apply tighter criteria.

Non-standard construction can include (for example):

• Timber frame
• Concrete panel systems
• Steel frame structures
• System-built or modular construction

What this can mean for you:

• Some lenders may decline
• Others may require additional surveys or specialist input
• Deposit requirements and product availability can be affected

Things to consider for resale and future lending

Even if a mortgage is available now, it’s worth thinking about how the property may be viewed later—especially if you plan to remortgage or sell.

For maisonettes, resale and future lending can be influenced by:

• Remaining lease length (for leasehold)
• Service charge history and expected future costs
• Whether the property is above commercial premises
• Any restrictions or complexities in the lease or building arrangements

Summary

A mortgage on a maisonette is often possible, but the best route depends on the property’s ownership structure and the details lenders assess. In particular, lenders commonly focus on lease length, service charges, shared freehold management, mixed-use configuration (above shops), and construction type.

If you’re comparing options, it helps to concentrate on the practical elements that affect affordability and long-term mortgageability—so you can choose a maisonette that is more likely to remain financeable over time.
