A Limited Company Mortgage Brokers message | Many landlords are opting for limited company buy-to-let mortgages due to the potential tax advantages they offer. One key benefit is the ability to offset mortgage interest against rental profits, which can lead to significant savings—particularly for higher-rate taxpayers. In addition, limited companies pay corporation tax rather than income tax, which is often more favourable when it comes to reinvesting profits and planning for long-term growth.
As tenant demand continues to rise—especially in high-density urban areas and popular university towns—property investment through limited companies is becoming an increasingly attractive strategy for building sustained wealth. The structure enhances tax efficiency and provides greater flexibility for succession planning, profit retention, and portfolio expansion.
Given these advantages, limited company mortgage brokers must provide tailored, strategic advice that reflects the specific needs of limited company investors. Whether clients are seasoned landlords expanding their portfolios or first-time investors exploring corporate structures, brokers must be equipped to guide them through the nuances of this growing segment of the buy-to-let market.
Why Limited Companies Need Bespoke Mortgage Advice
Conventional buy-to-let lending often doesn’t account for the nuances of company structures. Lenders apply stricter affordability metrics and expect brokers to present robust documentation, including company accounts, SPV details, and director guarantees.
As a dedicated limited company mortgage adviser, your role includes:
Identifying lenders that specialise in company-based lending structures
Evaluating stress testing models unique to limited companies
Optimising property portfolio structures for tax and leverage efficiency
Advising on refinancing, equity release, and cross-charging strategies
💡 Did You Know?
In 2023, over 70% of new buy-to-let applications were made through limited companies—a fivefold increase since 2016, driven by Section 24 tax reform.

Understanding Lender Expectations for Limited Companies
Most lenders begin applying advanced underwriting protocols once a company owns four or more mortgaged properties. Here’s what mortgage brokers should keep in mind:
Full Portfolio Review – Lenders assess not just one property but the entire portfolio’s performance under the company.
Rental Stress Tests – Common thresholds range from 125% to 170% of the mortgage interest at a notional rate (usually 5.5%+).
Experience Thresholds – Expect lenders to require directors to have at least 2 years of landlord experience.
Valuation Methods – HMOs and multi-lets are typically income-based rather than using market comparables, which impacts LTV potential.

Buying through a limited company may seem complex at first. However, with the right advice and planning, it can offer significant advantages.
This approach can help with tax planning, long-term growth, and managing multiple buy-to-let properties under one structure.
But it’s not without challenges. These include tighter lending rules, higher interest rates, and added legal responsibilities.
