A limited-company buy-to-let strategy built around complex income and portfolio liquidity
An experienced landlord wanted to add another rental property without committing more capital than necessary. The recommendation combined a 35% deposit with specialist underwriting that considered recurring income, liquid assets, landlord experience and the rent achievable on the new property.

Steve assessed the client’s recurring income, liquid assets, existing rental portfolio and intended property together, then identified a lender prepared to consider the case subject to the new property meeting the required rental assessment.
The case at a glance
- The challenge
- A financially strong portfolio landlord had substantial assets, but recurring income came from savings interest, taxable benefits and UK property income rather than a conventional salary.
- The recommendation
- A 65% loan-to-value, interest-only buy-to-let mortgage over 25 years, fixed for two years, subject to the selected property meeting the lender’s rental requirements.
- The intended benefit
- Acquire another property through the limited company while retaining more liquid capital for future opportunities, costs and contingencies.
Strong assets did not mean a standard underwriting route.
The client was an experienced landlord with three existing buy-to-let properties held through an investment company. He wanted to add a further property using a substantial deposit from liquid investments while keeping enough capital available for future acquisitions, maintenance, void periods and other portfolio needs.
The proposed borrowing was conservative at 65% loan-to-value. The complexity came from the way the client’s income appeared on paper. His recurring income was made up mainly of savings interest, taxable benefits and UK property income rather than employment income or a conventional director’s salary.
- Separate sustainable income from one-off gains The latest tax return showed a materially higher total because it included a one-off crystallisation of investment gains. The recommendation did not rely on that exceptional figure as if it were recurring income.
- Assess the landlord as well as the company The lender needed to understand the client’s personal financial strength, liquidity and track record alongside the limited-company borrowing structure.
- Make the property support the debt The full loan remained dependent on the chosen property achieving sufficient rent under the lender’s stress test and, where relevant, the valuer’s assessment of market rent.
That meant the lender could not be selected on headline rate alone. The underwriting approach had to fit both the borrower’s financial profile and the economics of the property eventually purchased.
Balance leverage with the liquidity the portfolio still needed.
Steve recommended an interest-only mortgage over 25 years at 65% loan-to-value, using a deposit of approximately 35%. The selected product was fixed for two years and allowed annual overpayments of up to 10%, giving the client a defined period of payment certainty with some ability to reduce the balance if priorities changed.
-
Keep the deposit substantial but not excessive
A 35% deposit reduced leverage and supported lender appetite without tying up more liquid investment capital than the client considered necessary.
-
Use interest-only borrowing for portfolio flexibility
Rather than directing rental cash flow towards scheduled capital repayment, the structure kept more cash available within the wider investment strategy.
-
Match the property to the lender’s rent requirement
The recommendation only worked at the intended loan size if the selected property produced, or was valued as capable of producing, sufficient rent under the lender’s assessment.
The product carried a 3% lender arrangement fee. The fee could be added to the mortgage, preserving more cash at completion, or paid upfront to avoid increasing the balance on which interest would be charged.
Use the client’s real financial strength without overstating income.
The recommendation was built around evidence that could be defended: recurring income, liquid assets, landlord experience and the performance expected from the new property. It did not depend on treating a one-off investment gain as sustainable earnings simply because it appeared on the latest tax return.
This distinction mattered. A specialist lender could consider the wider financial picture, but the property still had to stand up to buy-to-let underwriting in its own right. A more expensive property with weaker rent could have failed the stress test even if the client had ample personal assets to complete the purchase.
The 65% loan-to-value therefore acted as a practical middle ground. A larger deposit might have improved rental coverage and reduced interest cost, but would have concentrated more capital in one asset. More leverage could have preserved extra liquidity, but potentially at the cost of lender choice, pricing or rental affordability.
The intended result was to finance another limited-company buy-to-let purchase while preserving meaningful liquidity, provided the chosen property met the lender’s valuation and rental requirements.
Understanding this type of buy-to-let recommendation.
Can a limited-company buy-to-let lender consider complex personal income?
Potentially. Lender treatment varies. Some focus primarily on the property’s rent while also assessing the directors’ income, assets, experience and wider portfolio. Non-standard income therefore needs to be matched with a lender whose underwriting approach fits the complete case.
Does a large deposit remove the need for rental stress-testing?
No. A lower loan-to-value can help, but the proposed rent still needs to support the borrowing under the lender’s calculation. In this case, the available loan depended on the selected property meeting the required rental level.
Why might a landlord choose interest-only borrowing?
Interest-only can preserve cash flow for other investments, costs or contingencies because scheduled payments do not include capital repayment. The trade-off is that the capital remains outstanding and must be repaid through an appropriate repayment strategy.
Can a buy-to-let arrangement fee be added to the mortgage?
Some products allow this, subject to lender criteria and loan-to-value limits. Adding the fee can preserve cash at completion, but it increases the mortgage balance and may increase the total interest paid.
A strong balance sheet can still need the right underwriting route.
If you are buying through a limited company, expanding an established portfolio or have income that does not fit a conventional salary profile, start with an assessment of the property, rent, assets and wider borrowing strategy together.
