SPV Mortgage

An SPV mortgage is a buy to let mortgage taken out by a Special Purpose Vehicle, which is a limited company set up specifically to hold and manage rental property. The company exists for that single purpose and cannot carry out any other trading activity. Most UK buy to let lenders now offer SPV products, and around 80% of new rental property purchases are made through this type of structure.

This guide explains what an SPV is, how to set one up, what lenders require, how your income is assessed, and how SPV mortgages compare with personal buy to let borrowing.

What Is an SPV?

SPV stands for Special Purpose Vehicle. In the context of property investment, it is a limited company incorporated at Companies House whose sole activity is buying, owning, and letting residential property. The company is a separate legal entity from its directors and shareholders, which means it owns the property in its own right, pays its own tax, and files its own accounts.

The key difference between an SPV and a standard trading limited company is scope. A trading company can do many things: provide services, sell goods, employ staff. An SPV is restricted to property activities only. Lenders insist on this restriction because it reduces the risk. The company cannot accumulate debts from unrelated business activities that could affect the property or the mortgage.

SIC Codes for Property SPVs

When you register your SPV at Companies House, you must select the correct Standard Industrial Classification (SIC) codes. These codes tell Companies House, HMRC, and mortgage lenders what the company does. For a property SPV, the two most commonly accepted codes are:

• 68100: Buying and selling of own real estate. This covers companies that purchase property with the intention of holding, selling, or developing it.
• 68209: Other letting and operating of own or leased real estate. This is the most widely used code for buy to let SPVs and covers the letting and management of property owned by the company.

Some lenders also accept 68201 (renting and operating of Housing Association real estate) and 68320 (management of real estate on a fee or contract basis), but 68100 and 68209 are the safest choices. If you register with incorrect SIC codes, some lenders will decline the application outright. It is worth checking your company’s SIC codes before applying for a mortgage and updating them at Companies House if needed, which can be done via the confirmation statement at no extra cost.

How to Set Up a Property SPV

Setting up an SPV is straightforward and can be completed in a few steps:

1. Choose a company name: This can be anything that is not already in use and does not require special permission. Many investors use a variation of their name followed by “Properties” or “Investments”.
2. Register with Companies House: Online registration costs £12 and is usually processed within 24 hours. You will need to provide a registered office address, details of at least one director, details of shareholders, SIC codes (use 68100 and 68209), and a memorandum and articles of association (standard templates are available).
3. Open a business bank account: The company needs its own bank account. All rental income, mortgage payments, and expenses should flow through this account. Some high street banks offer free business accounts for the first year.
4. Register for corporation tax: HMRC requires notification within three months of the company starting to trade (in this case, receiving rental income or completing a property purchase).
5. Appoint an accountant: While not legally required, an accountant experienced in property companies is strongly recommended. They will prepare annual accounts, file corporation tax returns, and advise on dividend extraction strategy.

The entire process from registration to being mortgage ready can be completed within a few days.

Lender Criteria for SPV Mortgages

SPV mortgage criteria differ from personal buy to let in several important ways:

• Company structure: The company must be a genuine SPV with property related SIC codes. Trading companies or companies with non property activities are typically declined.
• Directors and shareholders: All directors and shareholders with more than a specified percentage (usually 20% to 25%) must be party to the application and provide personal guarantees.
• Deposit: Most lenders require a minimum 20% to 25% deposit (75% to 80% LTV). Some specialist lenders offer up to 85% LTV at higher rates.
• Rental coverage: The expected rent must cover at least 125% to 145% of the mortgage payment at a stress tested rate. The stress rate varies by lender but is typically the pay rate plus a margin or a minimum floor of around 5.5%.
• Credit history: Lenders check the personal credit files of all directors and shareholders. Adverse credit will restrict lender options but does not automatically prevent borrowing.
• Age limits: Most lenders set a maximum age for directors at the end of the mortgage term, commonly 75 to 85 years.
• Property type: Standard residential properties are accepted by most lenders. HMOs, multi unit blocks, and non standard construction have fewer options.

How Income Is Assessed

This is one of the most misunderstood aspects of SPV mortgages. Many investors assume that because the company is borrowing, their personal income does not matter. This is not the case with most lenders.

The primary affordability test is rental coverage: the rent must meet the lender’s interest coverage ratio. However, many lenders also require at least one director to demonstrate a minimum personal income, commonly £25,000 per year. This income can come from employment, self employment, pensions, or other sources. It does not need to come from the rental property itself.

Some lenders assess affordability purely on rental income without a personal income requirement, but these are less common and tend to be specialist providers. If your personal income is below the typical thresholds, a broker can identify which lenders will work with your circumstances.

For new SPVs with no trading history, lenders rely on projected rental income (usually evidenced by a letting agent’s rental assessment) and the directors’ personal financial position.

SPV Mortgage Rates

The rate premium on SPV mortgages compared with personal buy to let has narrowed significantly over recent years. As of early 2026, the difference is typically 0.1% to 0.5%. Competitive two year fixed rates for SPV mortgages start from around 4.5% to 5.5% at 75% LTV.

Rates vary depending on LTV, property type, company structure, and the number of properties in the portfolio. Five year fixes are also widely available and may offer slightly better rates in exchange for the longer commitment.

Most SPV buy to let mortgages are interest only, which keeps monthly payments low and maximises cash flow. The interest payments are a fully deductible business expense for corporation tax purposes.

Shareholder Requirements

Lenders pay close attention to who owns the SPV. The standard requirements include:

• All shareholders holding 20% to 25% or more of shares must be named on the application
• Shareholders must be UK residents in most cases, though some lenders accept expatriate or foreign national shareholders
• Corporate shareholders (where another company holds shares in the SPV) are accepted by a limited number of lenders
• Trust shareholders require specialist lender arrangements

Adding or removing shareholders after the mortgage completes may require lender consent. Some mortgage terms include a change of control clause that could trigger a full reassessment or require the mortgage to be repaid.

Multiple SPVs

Some investors choose to hold each property in a separate SPV. This approach has both advantages and drawbacks.

Reasons investors use multiple SPVs:

• Risk isolation: if one property has legal or financial problems, other properties are protected
• Easier to sell individual properties by selling the company rather than the property itself (a share sale rather than an asset sale, which can reduce SDLT for the buyer)
• Simpler accounting for joint venture properties where different investors are involved in different deals

Drawbacks of multiple SPVs:

• Higher administrative and accountancy costs (each company needs its own accounts, tax return, and confirmation statement)
• Some lenders limit the number of SPVs they will lend to per applicant
• The small profits rate of 19% corporation tax applies per company, so spreading properties across multiple SPVs can keep each company within the small profits band

For most investors with fewer than ten properties, a single SPV is the simpler and more cost effective approach. Larger portfolio landlords or those with joint venture arrangements may benefit from a multi SPV structure.

Portfolio Considerations

If you own four or more mortgaged buy to let properties (personally or through companies), you will be classified as a portfolio landlord under rules introduced by the Prudential Regulation Authority in 2017. Portfolio landlord applications require additional documentation including a full portfolio schedule with property values, outstanding mortgages, rental income, and void periods.

Not all lenders apply portfolio lending rules to SPV applications, but many do. This is an area where broker advice is particularly valuable, as the right lender choice can simplify the application considerably.

Pros and Cons: SPV vs Personal Ownership

Advantages of an SPV

• Full mortgage interest deduction (not affected by Section 24)
• Corporation tax at 19% to 25% instead of income tax at up to 45%
• Profits can be retained and reinvested without additional personal tax
• Limited liability (though personal guarantees reduce this benefit)
• Easier succession planning through share transfers
• Rate premium over personal buy to let is now minimal

Disadvantages of an SPV

• Annual compliance costs: accountancy, Companies House filings, corporation tax returns
• Dividend extraction triggers additional personal tax
• Fewer lender options than the personal buy to let market
• SDLT surcharge of 5% applies to every company purchase
• Transferring existing personal properties into an SPV incurs SDLT and potentially CGT
• Mortgage products are typically interest only, which means no equity is built through repayment
• Some insurance products cost more for company owned properties

When an SPV Makes Sense

An SPV structure is generally most beneficial if you pay income tax at the higher or additional rate, if you plan to grow a portfolio rather than hold a single property, and if you can afford to leave profits within the company rather than extracting them all as dividends. For basic rate taxpayers with one or two properties who need the rental income for personal expenses, a personal buy to let mortgage may still be the better option.
