SPV vs Trading Company for a Mortgage

The type of company you buy property through decides which lenders will even look at you. A clean special purpose vehicle opens the market; a trading company narrows it sharply and costs more. Here is why, and what to do about it.

The short answer

A special purpose vehicle, or SPV, is a company set up solely to hold and let property. A trading company does something else as its main activity, such as running a shop or a consultancy, and also holds property. Buy to let lenders strongly prefer an SPV because it is clean and easy to underwrite, with no unrelated debts or liabilities. A trading company can still borrow, but from a much smaller lender panel, usually at a higher rate and with more scrutiny of the trading side. For most landlords a dedicated SPV is the right structure.

What separates an SPV from a trading company

A special purpose vehicle is a limited company that exists to do one thing: own and let property. It has property SIC codes, no other activity, and a balance sheet that is simply the properties, the mortgages and the directors loans behind them. A trading company, by contrast, has a primary business, retail, construction, consultancy, and holds property alongside it.

Both are limited companies and both can own buy to let property. The difference that matters to a lender is not the legal form but the cleanliness. An SPV has nothing else going on. A trading company brings its trading debts, creditors, staff liabilities and commercial risk into the same entity that holds the property.

Both routes sit under the wider limited company property finance decision. If you have not yet checked whether a company suits you at all, start with can a limited company get a mortgage.

Why lenders prefer an SPV

Buy to let lenders secure their loan against the property and take a personal guarantee from the directors. In an SPV, that security is uncomplicated: if the loan needs enforcing, there are no competing creditors and no unrelated liabilities muddying the position. The lender can underwrite the case in a day because there is nothing to untangle.

A trading company complicates every part of that. The lender has to assess the health of the trading business, worry about its creditors ranking against the property, and price the risk that trouble in the trade drags down the property. Most specialist buy to let lenders simply decline to lend to a trading company rather than do that work.

When a trading company gets used anyway

Sometimes a landlord already holds property inside a trading company, perhaps a business owner who bought their premises or an investment property through the company that runs their main business. Borrowing against it is possible, just from a smaller pool of lenders willing to look at the trading side.

Where this comes up, the usual advice is to separate the property into a dedicated SPV, either now or over time, so future borrowing is not constrained. Moving property between your own companies is still a sale for tax purposes, so it carries the same stamp duty and capital gains considerations as any other transfer and needs planning.

Get the SIC codes right whichever route you take

Lenders check that a company holding property carries the correct property SIC codes. A trading company that has never updated its codes to reflect property activity is a common cause of avoidable declines. Our SIC codes guide lists exactly what lenders expect.

See SIC codes for property companies for the codes, and transferring buy to let to a limited company for the tax cost of moving property between entities.

How to set your structure up

For most landlords starting out, the answer is simple: incorporate a fresh SPV with the right property SIC codes and hold the buy to let inside it, kept entirely separate from any business you trade through. This gives you the widest lender panel and the keenest rates from the first purchase onwards.

We arrange finance for both structures and can advise on which lenders will look at a trading company case.

FAQ

SPV vs Trading Company for a Mortgage: common questions

Can an SPV be a trading company?

No, the two are opposites by definition. A special purpose vehicle exists solely to hold and let property with no other activity, which is exactly what makes it clean for lenders. Once a company trades in something else as well, it is a trading company for lending purposes, and the buy to let lender panel narrows accordingly.

What is an SPV in a mortgage?

An SPV is a limited company set up only to own and let property, used as the borrower on a company buy to let mortgage. Lenders favour it because the security is clean: the company holds nothing but the properties, their mortgages and the directors loans behind them, so there are no unrelated creditors or liabilities to complicate enforcement.

Is it easier to get a mortgage as a limited company or a sole trader?

For buy to let, a clean SPV is straightforward and lent to by a wide specialist panel, though at higher rates than personal buy to let. A sole trader is assessed on personal income for a personal mortgage. They are different products for different purposes. Most portfolio landlords choose an SPV for the tax treatment of rental income rather than for ease alone.

What are the disadvantages of an SPV?

An SPV carries the running costs of a company: accounts, filing and an accountant. Company buy to let rates are higher than personal buy to let, and drawing profit out as dividends brings a second layer of personal tax. There is also the cost of moving any existing personally held property in. For a higher rate portfolio landlord the tax saving usually outweighs these; for a basic rate landlord it may not.
