What's the current landscape for limited company buy-to-let mortgages? Are rates significantly higher than personal mortgages, and what are the typical deposit requirements and lender criteria for a new SPV (Special Purpose Vehicle) company with no trading history?
Quick Answer
Limited company buy-to-let mortgages for new SPVs typically require 25-40% deposits, with rates around 5.5-6.5%. Lenders assess the directors' experience and the property's rental income, often with stricter stress tests than individual applications.
## Understanding Limited Company Buy-to-Let Mortgages
The limited company buy-to-let (BTL) mortgage landscape for new Special Purpose Vehicle (SPV) companies, particularly those without a trading history, requires a clear understanding of current rates and criteria. As of December 2025, typical BTL mortgage rates range from 5.0-6.5% for 2-year fixed and 5.5-6.0% for 5-year fixed products. Limited company rates are generally 0.5-1.0 percentage points higher than those offered to individual landlords due to the perceived additional complexity and risk.
The primary driver for limited company mortgages, despite the higher rates, is to mitigate the impact of Section 24, which since April 2020 has prevented individual landlords from deducting mortgage interest from rental income when calculating income tax. Companies, however, can still deduct all finance costs as an allowable expense before Corporation Tax is applied. Corporation Tax is 19% for profits under £50k, rising to 25% for profits over £250k.
## Deposit Requirements and Lender Criteria for New SPVs
For a new SPV company with no trading history, deposit requirements are typically higher than for an individual BTL purchase. Expect to put down a minimum of 25% of the property value, with many lenders requiring 30-40%. This higher deposit requirement reflects the lack of company track record and the lender's reliance on the directors' personal financial stability and property experience.
Lender criteria for new SPVs focus heavily on the experience of the directors. While the company itself might be new, lenders will assess the directors' individual property portfolios, their experience as landlords, and their personal credit histories. Some lenders may also require personal guarantees from the directors, meaning they would be personally liable for the mortgage if the company defaults. Rental income stress testing is standard: 125% rental coverage at a notional rate of 5.5% is common, ensuring the rental income can comfortably cover the mortgage payments.
### Practical Implications for Investors
An investor buying a £200,000 property through a new SPV might need a deposit of £50,000-£80,000. On a £150,000 mortgage at 6% interest, the annual repayment would be £9,000 (£750 per month). The property would need to generate at least £825 per month in rent to pass the 125% stress test at the 5.5% notional rate (effectively 140% at 6%). This ensures the investment is robust enough to cover servicing the debt.
For Stamp Duty Land Tax (SDLT), the additional dwelling surcharge of 5% applies to limited company purchases, meaning a £250,000 residential property would incur 5% on £250k, plus the standard rates, often resulting in a significant upfront cost. A £250,000 property would incur standard SDLT (2% on £125k-£250k) plus the 5% surcharge, totalling around £13,750 for SDLT alone, not including the legal and valuation fees.
## Lender Assessment Beyond the Balance Sheet
Given the absence of a trading history, lenders on limited company BTL mortgages scrutinise the property itself and the proposed tenancy. They will assess the property's rental valuation, its condition, and its postcode desirability. The projected rental income is key to the stress test calculation. Lenders look for strong rental demand in the area to minimise void periods and ensure the income stream is stable.
Moreover, the business plan for the SPV is often reviewed. While not a formal requirement for all lenders, having a clear strategy for the property's acquisition, management, and long-term goals can be beneficial during the application process. This can include details on the type of tenants anticipated and how the property will be managed. For `limited company BTL rates`, comparison sites and specialist mortgage brokers are essential resources.
## Tax Implications and `SPV mortgage requirements`
The primary tax advantage for limited company BTLs lies in the deductibility of all finance costs as expenses before Corporation Tax. For a higher rate taxpayer, this can mean a significant saving compared to an individual ownership model under Section 24. For instance, mortgage interest that would be restricted to a 20% tax credit for an individual is fully deductible for a company, reducing its taxable profit. Income tax is instead paid by the directors on dividends, usually at lower rates.
Investors also need to consider Capital Gains Tax (CGT). While individuals pay 18% or 24% on residential property gains (after a £3,000 annual exempt amount), companies pay Corporation Tax on their gains. This can make the `BTL investment vehicle` an attractive option for long-term portfolio growth, though extracting funds can incur further tax liabilities for directors.
## Investor Rule of Thumb
An SPV is primarily a tax-efficient vehicle for property growth, not a shortcut to cheaper finance; higher leverage or lower deposits mean higher rates and stricter criteria.
## What This Means For You
Navigating limited company mortgages requires a thorough understanding of the specific criteria, higher deposits, and increased rates. The trade-off is often the tax efficiency provided by deducting all finance costs, which can significantly improve net profitability for portfolio landlords. Understanding these intricacies is critical for making informed decisions, and this is precisely the kind of analysis we share within Property Legacy Education.
Steven's Take
The shift in tax legislation with Section 24 fundamentally changed how profitable property investment is for individual landlords. Limited companies, especially SPVs, became the go-to structure for new acquisitions for many. While rates are higher and deposits larger, the ability to deduct all mortgage interest before Corporation Tax often outweighs these costs for higher-rate taxpayers expanding their portfolio. I've personally used SPVs extensively to build my portfolio, and the key is always to factor in the higher mortgage costs and stricter stress tests from the outset. Don't compare limited company rates directly to residential rates; compare them to an individual BTL after tax, and the picture becomes clearer.
What You Can Do Next
Consult a specialist limited company mortgage broker: Use a broker that specialises in limited company BTLs, such as those found via NACFB (National Association of Commercial Finance Brokers), to compare rates and understand specific lender criteria.
Engage a property tax accountant: Before setting up an SPV, speak to an accountant specialising in property investment (search 'property tax accountant' on ICAEW.com) to assess the tax implications for your personal circumstances.
Research your local Council Tax policy: Check your specific local council's website for any local premiums on second homes or empty properties that might apply if the property is not immediately let out.
Calculate your true return on investment (ROI): Factor in the higher BTL interest rates (5.5-6.5%), increased SDLT due to the 5% surcharge, and Corporation Tax rates (19-25%) when projecting your profitability.
Prepare a robust business plan: Even if not explicitly requested, have a clear plan detailing your property strategy, rental projections, and management approach, which can strengthen your application.
