If you are buying a rental property, one of the first decisions is who will own it. You might buy in your own name, jointly with another person or through a limited company. The mortgage needs to fit that ownership structure from the beginning.
A company is not automatically the better choice because you are a higher rate taxpayer or plan to own several properties. The useful comparison combines borrowing costs, tax advice, administration and what you intend to do with the rental profits.
Start with the ownership plan
For a personal purchase, the individual owners normally apply for the mortgage. For a company purchase, the company is the borrower, although lenders also assess relevant individuals behind it.
Some buy to let lenders require a special purpose vehicle, often called an SPV, with permitted property activities.
An existing company that trades in an unrelated business may not meet the same criteria. Check the proposed structure before setting up a company or paying application costs.
Compare mortgage costs on the same basis
Ask for a comparison using the same loan amount, expected property value and realistic borrowing period. Look at the interest rate alongside product fees, valuation costs, legal fees and any broker fee.
A lower rate with a large fee may cost more than another option over the period you expect to keep the loan.
Adding a fee to the mortgage can also mean paying interest on that fee. The affordability assessment and available lenders may differ between personal and company applications.
A company mortgage can still involve personal liability
Lenders may require personal guarantees from directors or other relevant individuals. A guarantee can make you personally responsible for the company's mortgage obligations under its terms. Independent legal advice may be required.
Ask who must give a guarantee, what it covers and whether company changes need the lender's consent. Do not assume that using a limited company protects your personal assets from every risk connected with borrowing.
Keep tax advice separate from the mortgage comparison
For individual residential landlords, relief for qualifying finance costs generally takes the form of a basic rate Income Tax reduction, subject to the rules and limits. Companies are not subject to that particular restriction, but that does not establish which structure gives you the better overall result.
An accountant should consider rental profits, how money will be withdrawn, other income and your longer term plans. Moving an existing property into a company can have tax and legal consequences, including possible transaction taxes and Capital Gains Tax. It is not simply a mortgage product switch.
Questions to settle before making an offer
• Will rental profits be retained for future purchases or used for living costs?
• Who will be the shareholders and directors?
• Where will the deposit come from, and how will that be documented?
• Are you buying a new property or considering transferring an existing one?
• What are the estimated mortgage, legal, tax and annual accounting costs?
For an England or Northern Ireland purchase, ask your solicitor to calculate the Stamp Duty Land Tax position for the actual transaction. Company and additional property rules need checking, rather than assuming the standard homebuyer calculation applies.
Bring the advisers together early
PMS Mortgages can investigate mortgage options for the proposed borrower and property. Your accountant and solicitor should advise on tax and legal structure. Getting those answers before applying can help prevent a borrowing decision from being built around the wrong ownership assumption.

No. Compare mortgage costs, tax advice, administration and how rental profits will be used. The suitable ownership structure depends on the actual circumstances.
A lender may require a personal guarantee. Ask a solicitor to explain its scope before signing and check which individuals must provide one.
An ownership transfer involves more than a rate switch. Obtain tax and legal advice about the transaction before committing to a new mortgage.
