Company Buy-to-Let Guide: remortgaging a personal buy-to-let into an SPV

Overview: “remortgage” in everyday terms vs what lenders/legal documents treat as

Landlords often use the word remortgage to describe moving a buy-to-let from their personal name into a Limited Company or Special Purpose Vehicle (SPV).

In practice, this is often not a straightforward remortgage. Because the property is moving to a different legal owner (you personally → the company), the transaction is commonly treated as a sale and purchase.

That difference matters because it can affect:

• whether your existing mortgage can simply be “swapped”
• the type of underwriting the lender applies
• the costs involved (valuation, legal work, potential redemption)
• how stamp duty and capital gains tax may apply

How the mechanics usually work

1) The property is transferred into the company

When the property transfers into the company, the company becomes the owner. From the lender’s perspective, the company is usually buying the property (even if the end result is that the landlord continues to rent it out).

2) The existing personal mortgage is usually redeemed

If your personal buy-to-let has a mortgage, it generally needs to be redeemed as part of the transfer process.

That can mean:

• checking whether there are early repayment charges or redemption penalties
• allowing time for redemption, valuation and completion steps

3) The company then applies for a company/SPV buy-to-let mortgage

Once the company is the owner, it can arrange borrowing in its own name.

This is where underwriting can differ from personal buy-to-let lending, including how rental income is assessed.

Why it’s often treated as a purchase (and not a remortgage)

A true personal remortgage usually keeps the same borrower and the same legal ownership.

With a Limited Company/SPV restructure, the borrower changes and the property’s ownership changes. That typically leads to additional requirements compared with a standard remortgage, such as:

• fresh valuation for the company mortgage
• legal work for the transfer and completion
• potential stamp duty implications for the company

Even if the end goal is to refinance, the legal structure can make the process closer to buying a property than remortgaging it.

Mortgage underwriting: what can change when it becomes an SPV

Rental coverage requirements may be different

One of the reasons landlords explore company/SPV lending is that rental coverage requirements can differ from personal buy-to-let criteria.

Exact requirements vary by lender and deal, but the principle is consistent: the company’s mortgage affordability assessment may not mirror the personal buy-to-let approach.

This can be relevant where a landlord’s personal remortgage options are constrained by coverage calculations.

The lender will look at the company’s deposit/equity position

When the property moves into the company, lenders will usually focus on the equity available and how it supports the loan-to-value.

In many cases, the equity in the existing property can be treated as the company’s deposit contribution, but this is still subject to:

• the lender’s valuation
• the company mortgage terms
• any minimum deposit/equity expectations

Company structure and documentation expectations

Company/SPV lending often expects the company to be set up appropriately for property letting, with relevant activities and documentation.

Lenders may also expect evidence of how the company will operate (for example, the business banking arrangements and the overall transaction trail).

Costs and timing: what to plan for

Because the restructure can be treated as a purchase, costs can be broader than a simple remortgage.

Common cost areas include:

• redemption costs for the personal mortgage
• valuation for the company mortgage
• legal fees for transfer and mortgage completion

It’s also worth building in time for the full sequence of events (redemption, transfer, valuation, underwriting, completion).

Deposit sources and how an “existing mortgage” fits in

If you’re moving an existing personal buy-to-let into a company, the deposit question is usually answered by equity rather than cash savings alone.

However, lenders may still require additional funds in some situations, for example if:

• the available equity doesn’t meet the lender’s expectations after valuation
• the transaction structure affects how much equity can be used

Tax considerations: why professional input is important

Tax outcomes are fact-specific, but the restructure commonly brings tax into the spotlight.

Stamp Duty Land Tax (SDLT)

Because the company is acquiring the property, SDLT may be payable.

Capital Gains Tax (CGT)

If you are treated as selling the property to the company, CGT may arise on any gain.

Incorporation Relief (where relevant)

In some circumstances, landlords may consider whether Incorporation Relief could apply.

These rules can be complex and depend on the details of the transaction and the landlord’s circumstances, so it’s usually sensible to involve a solicitor and/or accountant.

Limited Company vs SPV: does it change the “remortgage” question?

Both Limited Companies and SPVs can be used for buy-to-let, but the key point for this page is the same: once the property is transferred into a company, the transaction is typically treated as a change of ownership.

That means the process is usually closer to a sale and purchase than a conventional remortgage, regardless of whether the company is branded as an SPV.

Key decision points for landlords considering the restructure

Before proceeding, landlords typically need to weigh up:

• whether the transaction is likely to be treated as a sale and purchase (with SDLT/legal implications) rather than a simple remortgage
• whether redeeming the personal mortgage triggers penalties
• whether the company/SPV mortgage is likely to meet rental coverage requirements
• whether the company can satisfy deposit/equity expectations based on lender valuation
• the overall impact of SDLT and CGT, including whether any reliefs may be relevant

Bottom line

An existing personal buy-to-let can often be moved into a Limited Company or SPV, but it’s frequently not a straightforward remortgage.

Because the property’s ownership changes, the process commonly involves redeeming the personal mortgage, transferring the property to the company, and then arranging a new company buy-to-let mortgage—along with additional legal, valuation and potential tax considerations.

Planning the restructure with the mortgage mechanics, costs, rental coverage and tax position in mind is usually the most reliable way to understand whether the move is likely to work financially.
