Limited company buy-to-let mortgages (LTD/SPV)

A limited company buy-to-let mortgage is a buy-to-let loan where the borrower is the company, not an individual landlord. In many cases, the company is set up as a Special Purpose Vehicle (SPV)—a limited company created specifically to buy and hold one or more investment properties.

Because the mortgage is underwritten against the company's risk and rental performance, limited company buy-to-let is usually more specialist than personal buy-to-let. That can mean a different application experience, different documentation, and (often) different pricing.

Note: This is general information. Mortgage criteria, costs and availability vary by lender and by case.

What is a limited company buy-to-let?

With a limited company buy-to-let mortgage, the lender advances funds to purchase a property intended to be rented out. The limited company:

• owns the property
• makes the mortgage payments
• receives the rental income (and accounts for it within the company)

From an underwriting perspective, lenders are assessing whether the company can meet repayments over the term. That assessment is typically based on expected rental income, the structure of the arrangement, and information about the people connected to the company.

Why use an LTD/SPV for buy-to-let?

Landlords choose limited company structures for a range of reasons. Common motivations include:

1) A separate legal entity for the property business

Using a company can create a distinct ownership framework for investment activity.

2) Portfolio planning and ownership structure

Where landlords plan to build a portfolio, an SPV can provide a consistent structure for buying and holding assets.

3) Different treatment of profits within a company

Rental profits are generally reflected through the company's accounts and corporation tax rather than being treated as personal income.

4) Practical governance where more than one investor is involved

If multiple parties are involved, a company can make it easier to reflect ownership and decision-making through shareholdings and director arrangements.

Is there a special type of limited company for buy-to-let?

Most lenders that offer limited company buy-to-let lending focus on SPVs.

An SPV is usually created with the intention of buying and managing investment property. Because the company's purpose is clear, lenders often find it easier to understand the model and assess risk.

SPV vs trading company: why it matters to lenders

Not every limited company is treated the same way by buy-to-let lenders.

• SPV (Special Purpose Vehicle): set up and operated in a way that is consistent with property investment/letting activity. The company's income is expected to come mainly from the property and the rent it generates.
• Trading company: if the limited company also receives income from other business activities (for example, a wider trade or services unrelated to property letting), it may be viewed as a trading company.

In practice, lenders can be more cautious where there are additional income streams and business activities, because the mortgage decision is still fundamentally tied to the property and the rental income supporting the loan. Where unrelated trading activity is present, it can be harder to separate the buy-to-let risk from other business risks.

Other company structures may exist, but availability and underwriting approach can vary.

Can you get a limited company buy-to-let mortgage?

Limited company buy-to-let mortgages are typically more specialist than standard personal buy-to-let. That often means:

• fewer lenders offering the product
• more detailed underwriting
• criteria that can differ noticeably between lenders

In many cases, lenders place significant weight on expected rental income and whether it supports the mortgage payments, alongside information about the company and—where relevant—the individuals behind it.

What lenders usually focus on

There isn't one universal set of rules across all lenders, but several themes come up frequently.

Loan-to-value (LTV)

Maximum LTVs for limited company buy-to-let are often lower than those seen in mainstream residential lending. This can mean a larger deposit is commonly required.

Rental coverage (income vs mortgage payments)

Lenders typically assess whether the rent is likely to provide sufficient coverage for the monthly mortgage cost. This is often expressed as a rental coverage requirement.

Company and director information

Even though the borrower is the company, lenders may still request information about the directors—particularly where the company is newly formed or where risk factors exist.

Depending on the case, lenders may also look for additional assurance around repayment.

Director involvement and personal guarantees

Some limited company buy-to-let mortgages may require a director's guarantee (or similar personal support). This is sometimes used to provide the lender with additional comfort about how the mortgage will be managed if rental income is under pressure.

A director's guarantee is a contractual commitment that can create personal exposure if the company cannot meet the mortgage obligations, so it's worth understanding the commitment before agreeing to it.

While requirements differ, lenders commonly review factors such as:

• director background and experience
• how the company will operate in practice
• the company's financial position and supporting evidence

The exact approach varies by lender, the structure of the application, and the overall risk profile.

Portfolio size, experience and concentration

Some lenders prefer established landlords or entities with a track record. Others may consider new entrants depending on the overall risk profile.

Where portfolio size is relevant, lenders may apply their own limits based on total exposure and concentration.

Property type and tenant profile

Many property and tenancy considerations mirror standard buy-to-let practice, such as:

• property condition and construction
• whether the tenancy is standard or more specialist
• tenant type and any restrictions that may apply

Availability can vary for niche property types, including HMOs.

Newly formed SPVs: what changes?

It may be possible to obtain limited company buy-to-let lending through a newly formed SPV. However, a new company may be viewed as higher risk because it has no established rental track record.

As a result, lenders may look for one or more of the following:

• a larger deposit and/or additional security
• stronger evidence of expected rental performance
• additional support from individuals connected to the company in some cases

If the company is already trading and has rental history, lenders may be able to assess performance more directly.

Setting up an SPV for limited company buy-to-let

Setting up an SPV involves registering the limited company and ensuring the company's activities align with the intended property business.

While requirements differ by lender, the company's SIC code (classification of business activity) is often relevant. Common SIC codes used in real estate letting and related activities include:

• 68100: Buying and selling own real estate
• 68201: Renting and operating of Housing Association real estate
• 68209: Other letting and operating of own or leased real estate
• 68320: Management of real estate on a fee or contract basis

Choosing a structure that reflects how the company will operate in practice can help ensure the application is presented consistently.

Advantages and disadvantages of limited company buy-to-let

Limited company buy-to-let can be attractive, but it isn't always the simplest or most cost-effective route.

Potential advantages

• A formal structure for holding investment property
• Potentially different tax treatment of rental profits (depending on circumstances)
• A consistent framework for portfolio growth
• Ownership and profit arrangements can be easier to manage through the company

Common disadvantages

• Less lender choice: limited company products are offered by a smaller number of lenders
• Higher pricing is common: interest rates and overall costs can be higher than some personal buy-to-let options (varies by lender and case)
• Restructuring costs: moving an existing portfolio into an SPV can involve legal and tax considerations
• Ongoing administration: company accounts, bookkeeping and filing obligations must be managed

Because these factors can affect the overall investment economics, it's important to assess the full picture—not just the mortgage.

How limited company buy-to-let differs from personal buy-to-let

Even when the property and rental assumptions are similar, the application can feel different because the lender is underwriting a company.

In practice, that can mean:

• more emphasis on rental performance and the company's risk profile
• additional information requirements around directors and company structure
• underwriting that may be less straightforward for some cases

Limited company buy-to-let: key considerations for landlords

When planning a limited company buy-to-let, it helps to think about the building blocks lenders tend to expect:

• realistic rental assumptions and supporting documentation
• an appropriate deposit level for the LTV being sought
• a clear company setup (including SIC code and intended activity)
• director information and, where relevant, any additional support
• how the portfolio is expected to grow over time

Limited company buy-to-let and tax/SDLT implications (high level)

Limited company buy-to-let can involve tax and stamp duty considerations that differ from personal ownership.

Common areas landlords review include:

• how rental profits are taxed within a company (corporation tax)
• whether moving property into a company is treated as a disposal for tax purposes
• Stamp Duty Land Tax (SDLT), which is generally calculated based on the property's market value at the point of transfer

Because the tax position depends on the facts (including how the company is set up and how the property is acquired), it's often important to coordinate mortgage planning with specialist tax guidance.

Transferring property into a limited company: what to expect

If a landlord is considering moving a personally owned buy-to-let property into an SPV, it's important to understand that this is often treated as a sale at market value, rather than a simple transfer.

• Stamp Duty Land Tax (SDLT): when a company acquires property, SDLT is typically calculated based on the market value at the point of transfer. Additional SDLT rules (such as the higher rate for additional properties) may apply depending on the circumstances.
• Capital Gains Tax (CGT): a transfer into a company can create a CGT liability for the individual, based on the gain between the acquisition cost and the market value at transfer (subject to any reliefs). This is an area where specialist tax advice is usually essential.
• Mortgage restructuring: an existing mortgage held in personal names generally cannot be simply transferred into a company. In most cases, a new mortgage arrangement is required, which involves fresh underwriting and potentially different terms.
• Legal and administrative steps: the transfer typically requires conveyancing and may involve additional steps if the SPV is not already in place.

Because the outcome depends heavily on your circumstances and timing, restructuring is usually something to plan carefully rather than treat as a quick fix.

Risks and how landlords typically manage them

Limited company buy-to-let still carries the core buy-to-let risks—most importantly, that rental income may not always cover the mortgage costs.

Common risk areas include:

• void periods (property empty and no rent coming in)
• repairs and maintenance costs
• tenant-related issues that can affect rent collection
• interest rate and affordability pressure if circumstances change

Landlords often manage these risks by maintaining appropriate reserves, using robust property management arrangements, and ensuring rental assumptions are realistic.

The limited company buy-to-let process (what to expect)

Although lenders differ, the overall flow often looks like this:

1. Confirm the structure — decide how the property will be held (SPV/LTD) and how the company will operate.
2. Select a suitable lender/product — limited company lending is specialist, so product availability can depend on the property and company details.
3. Prepare documentation — gather company information, director/shareholder details, and rental evidence (where applicable).
4. Submission and lender assessment — the lender reviews the application and arranges a valuation.
5. Offer and completion — if the lender is satisfied, an offer is issued subject to conditions, and completion follows the usual conveyancing steps, with the company as the purchaser.

Costs and admin to budget for

Limited company buy-to-let can involve additional practical costs compared with personal ownership. Common areas to budget for include:

• Valuation and property-related costs (including any separate survey if you want more than the lender's basic valuation)
• Legal fees for the mortgage and any related property transactions
• Ongoing company administration, such as accounts, filings and compliance

When comparing options, it helps to consider not only the mortgage arrangement costs but also the long-term cost of running the company.

Remortgaging a limited company buy-to-let

Remortgaging through a limited company is broadly similar in principle to remortgaging a personal buy-to-let: the lender reassesses the case based on the property, rental performance and the company's circumstances.

In practice, the key differences tend to be:

• the lender's limited company underwriting approach
• the documentation and information required for the company and directors
• the fact that the mortgage is taken in the company's name, so the company's cashflow and rental record are central to the assessment

If you are considering moving property into an SPV (or between companies), it's also important to factor in that this may be treated differently from a standard remortgage, with potential SDLT and legal/tax implications.

Summary: is an LTD/SPV buy-to-let right for you?

A limited company buy-to-let mortgage can suit landlords who want a structured approach to ownership and portfolio planning, or who prefer to separate investment activity into a company.

It is typically more specialist than personal buy-to-let, with underwriting focused on rental performance and the company's risk profile. It can also involve additional costs and ongoing administration—and if you're moving an existing property into an SPV, the legal and tax implications of the transfer need to be factored in alongside the mortgage itself.

For many investors, the decision comes down to whether the mortgage and property economics work alongside the wider legal and tax implications of operating through a limited company.
