Main Types of Mortgages for Professional Landlords
Below is a summary of the main mortgage types available to professional landlords, with a brief description of each:
- Buy to Let Mortgages:
Specifically designed for landlords renting out properties. Typically require a 25% deposit and are assessed on rental income exceeding the mortgage payment by a set percentage (interest cover ratio). - Portfolio Mortgages:
Allow landlords to place all their buy-to-let properties under one mortgage with a single lender, simplifying management with one monthly payment and review date. Lenders assess the overall portfolio rather than individual properties. - Limited Company Mortgages:
Enable landlords to hold properties in a special purpose vehicle (SPV) company. Mortgage interest can be deducted from rental income as a business expense, offering potential tax efficiencies. - Commercial Mortgages:
Used for properties with mixed residential and commercial uses, such as retail with flats above or offices. Underwriting focuses on tenant strength and lease terms. Can be tailored for new purchases or refinancing, with terms from 2 to 30 years and interest-only options available. - HMO Mortgages:
For Houses in Multiple Occupation (HMOs), these require compliance with specific underwriting and licensing due to the complexities of multiple tenants. Often have higher yields but stricter criteria and deposit requirements. - Bridging Loans:
Provide short-term finance for quick property purchases or refurbishments, typically refinanced onto a long-term mortgage. Useful for auction purchases or rapid portfolio re-gearing. Commercial mortgages, Bridging loans and Development finance are offered via FD Commercial & Bridging Ltd

What is a Professional (Portfolio) Landlord?
A professional landlord is defined as a person owning 4 or more properties either in a personal name or via a limited company. A portfolio landlord is defined as someone who owns four or more rental properties. This definition was formalised in 2017 when the Prudential Regulation Authority (PRA) introduced new rules requiring lenders to assess the entire portfolio of any borrower meeting this threshold, rather than simply looking at the individual property being financed.
The distinction matters because it changes how lenders underwrite your application:
- Small-scale or accidental landlord: Owns 1–3 mortgaged properties, often with rental income as a secondary income source. Applications are assessed on a property-by-property basis.
- Professional landlord: Owns 4+ mortgaged properties, with rental profits forming a material part of their income. Lenders conduct a full portfolio-wide stress test before approving any new mortgage.
To secure a buy to let property mortgage, landlords must provide proof of rental income potential, usually confirmed by a professional.
Properties can be held in several structures:
- In personal names (sole or joint ownership)
- Within a special purpose vehicle (SPV) limited company, often using SIC code 68209
- Through more complex arrangements such as LLPs, trusts, or family investment companies
Landlords must have suitable building insurance that covers the full rebuild value of each buy to let property as a condition of the mortgage.
Professional landlords often let a diverse mix of property types. This might include standard AST (assured shorthold tenancy) houses and flats, houses in multiple occupation (HMOs), multi unit blocks (often called MUFBs), student accommodation, and mixed portfolios spread across different UK regions.
Lenders typically want to see at least 12–24 months of evidence showing consistent rental income before treating you as a professional borrower. Prior landlord experience—particularly a track record of managing tenancies, maintenance and finance without arrears—strengthens your application.
Example: A landlord with six terraced houses in Bristol and Cardiff, plus a five-bed HMO in Leeds, would comfortably meet the professional landlord definition. Their broker would present the whole portfolio to lenders, showing rental yields, current loan to values, and management track record for each property.
Types of Mortgages Available to Professional Landlords
Once you become a portfolio landlord, you can access a wider range of mortgage products, including specialist finance not typically available to casual property investors with one property or a handful of rentals.
Standard Buy to Let Mortgages
- Used for single AST properties let to individual tenants or families
- For a buy to let property, the maximum loan-to-value (LTV) ratio for a mortgage is typically 75%, meaning landlords need at least a 25% deposit (some lenders may stretch to 80% for strong cases)
- Often structured as interest-only, keeping the monthly payment lower than capital repayment options
- Fixed rates of 2, 5 or 10 years are common in 2025, with variable rates also available
- Best suited for straightforward purchases or remortgages where the property meets standard buy to let criteria
Portfolio Mortgages
- A single facility with one lender covering multiple properties under one loan
- One monthly payment and one review date, simplifying cash flow management
- Sits between standard buy to let and full commercial lending in terms of pricing, flexibility and criteria
- Particularly useful for landlords wanting to consolidate existing mortgages or release equity across several properties at once
- Can include cross-charges, meaning all properties in the facility are secured against the total loan
Commercial Mortgages for Landlords
- Used for mixed-use or fully commercial units—for example, retail with flats above, offices, or light industrial premises
- Loan sizes typically from £250,000 upwards through Fox Davidson’s lender panel
- Terms up to around 25–30 years, sometimes with interest-only periods
- Personal guarantees usually required from directors if held in a company
- Underwriting focuses on business viability, rental income and property type
Ltd Company Buy to Let Mortgages
- Common for professional landlords due to changes in mortgage interest tax relief since 2017
- Personal guarantees are usually required from directors and shareholders
- Underwritten more like commercial lending, particularly for larger portfolios
- Interest coverage ratios (ICRs) are often lower for limited company structures (around 125%) compared to personal name ownership (around 145%), making it easier to borrow in some cases
- Suited to landlords planning to hold properties long-term and reinvest rental profits within the company
Specialist Products
- HMO Mortgages: For licensed houses in multiple occupation, often requiring 3+ years landlord experience and specific lender criteria
- MUFB Mortgages: For blocks of multiple flats under one freehold, typically assessed on aggregate rental income
- Semi-Commercial Loans: For properties with mixed residential and commercial elements
- Bridging Finance: Short-term funding for auction purchases, heavy refurbishment, or rapid portfolio re-gearing—useful when speed matters more than long-term rate
Fox Davidson advises on selecting the most appropriate route for each property or portfolio strategy, balancing rate, flexibility and risk.
Mortgage Rates and Interest for Professional Landlords
Mortgage rates and interest are central to the success of any professional landlord’s buy to let strategy. For those managing a substantial property portfolio, even small differences in mortgage rates or arrangement fees can have a significant impact on overall borrowing costs and rental income. The mortgage market for portfolio landlords is highly competitive, with a wide range of mortgage products tailored specifically for landlords with multiple properties.
When considering buy to let mortgages, professional landlords will typically encounter interest rates ranging from 3% to 5% per annum. The exact rate offered depends on several factors, including the loan-to-value (LTV) ratio, the type of property, the size of the loan, and the lender’s appetite for risk. For example, a portfolio landlord seeking a mortgage at 75% LTV may face higher interest rates than one borrowing at 60% LTV, reflecting the increased risk to the lender.
Arrangement fees are another important consideration. These can range from 1% to 3% of the loan amount and are often added to the loan balance, increasing the total cost of borrowing over time. It’s essential for landlords to factor in these fees when comparing mortgage products, as a lower interest rate may be offset by a higher arrangement fee.
Professional landlords must also decide between fixed-rate and variable-rate mortgage products. Fixed-rate deals offer the security of a consistent monthly payment, making it easier to budget and plan for the future, an attractive option in a volatile interest rate environment. However, fixed-rate mortgages often come with early repayment charges if you wish to exit the deal before the end of the fixed period. Variable-rate mortgages, on the other hand, may offer more flexibility but can expose landlords to fluctuations in interest rates, which can affect cash flow and rental profits.
For some portfolio landlords, especially those with strong personal income, “top slicing” can be a useful tool. This approach allows lenders to consider personal income in addition to rental income when assessing affordability, potentially increasing the amount you can borrow. While not all lenders offer top slicing, it can be particularly beneficial for landlords looking to expand their property portfolio or invest in higher-value properties.
Given the complexity of the buy to let market and the variety of landlord mortgages available, working with a specialist mortgage broker is highly recommended. A broker with access to the entire mortgage market can help you compare rates, negotiate arrangement fees, and identify mortgage products specifically designed for professional landlords. This expert support can make a significant difference in securing the most competitive mortgage rates and terms, ultimately boosting your rental income and supporting the growth of your property portfolio.
In summary, understanding mortgage rates and interest is essential for professional landlords aiming to maximise returns and manage risk across their entire portfolio. By carefully evaluating loan-to-value ratios, arrangement fees, and the choice between fixed and variable rates and by seeking guidance from an experienced broker landlords can make informed decisions that support long-term property investment success in the buy to let market.
How Lenders Assess Professional Landlord Mortgage Applications
Since the PRA changes in 2017, underwriting for portfolio landlords has become significantly more detailed. Lenders now assess your whole portfolio rather than just the subject property, stress-testing your ability to manage rate rises and voids across all your holdings. In addition, lenders take into account various account-related factors such as your property portfolio, assets, liabilities, and cash flow forecast to assess mortgage applications.
Lenders also require a considerable amount of paperwork from professional landlords, including a business plan and a detailed breakdown of their property portfolio.
Affordability via Interest Cover Ratio (ICR)
The ICR measures whether your rental income can comfortably cover mortgage interest payments at a stressed rate. Typical parameters include:
Factor | Typical Range |
|---|---|
Coverage ratio | 125–145% |
Stress rate | 5–8% (depending on lender and product) |
Personal ownership ICR | Usually 145% |
Limited company ICR | Usually 125% |
2025 example: A property generating £1,500 per month rent may support a loan of approximately £250,000–£275,000 at 75% LTV, subject to individual lender tests. The exact figure depends on the stress rate applied and whether you hold the property in your personal name or a limited company.
Portfolio-wide Analysis
Lenders don’t just look at the new property—they review your entire portfolio:
- Total loan to value across all mortgaged properties (most lenders cap aggregate LTV at around 75%)
- Which units are high-yield and which are lower-yield, and how they balance out
- Void assumptions (typically 1–2 months per year) and maintenance cost allowances
- Cash flow projections and whether you hold contingency funds
Personal Profile
Your personal circumstances matter, even when borrowing through a company:
- Minimum income thresholds often start at £25,000 per annum, though around 32% of lenders are flexible if rental profits are strong enough
- Landlord experience and track record—lenders want to see no serious arrears, no recent repossessions, and competent property management
- Self employed landlords may need to provide SA302 tax calculations and tax year overviews
Property Types and Risk Weighting
Different property types attract different stress tests:
- Standard AST properties: standard ICR and stress rates
- HMOs: higher ICR requirements and often require 3+ years letting experience
- Student lets and holiday lets: specialist assessment with higher void allowances
- MUFBs: assessed on aggregate rental income with additional scrutiny on lease terms and management
Lenders may also cap their exposure to certain asset classes or geographic areas to manage concentration risk.
Credit Profile
- Clean credit is preferred – no CCJs, defaults or missed mortgage payments in the last 12–24 months
- Some specialist adverse-credit lenders exist for professional landlords with minor historic issues
- Up-to-date accounts and timely tax filings demonstrate financial discipline
Fox Davidson works with high-street banks, building societies, and specialist lenders to match criteria to each landlord’s profile and long-term goals.

Structuring and Growing a Professional Landlord Portfolio
Beyond securing a single mortgage, professional landlords should think in terms of long-term portfolio structure, gearing and tax efficiency. The decisions you make about ownership and finance can significantly impact your returns over a 10–20 year horizon.
Ownership Structures
The choice between holding properties in personal names versus an SPV limited company affects tax, lending criteria and exit flexibility:
Factor | Personal name | Limited company (SPV) |
|---|---|---|
Mortgage interest relief | Restricted to basic rate tax credit | Fully deductible as business expense |
Corporation tax on profits | N/A | Currently 19–25% |
ICR typically required | 145% | 125% |
Personal guarantees | Not applicable | Usually required |
Flexibility to extract funds | Straightforward | Requires salary, dividends or director’s loan |
Many portfolio landlords who started pre-2017 are gradually transferring new property acquisitions into SPVs, while retaining older holdings in personal names. This hybrid approach requires bespoke tax advice from a qualified accountant before restructuring.
Loan to Value Strategy
- Typical target gearing ranges from 60–75% LTV across the portfolio
- Equity release through remortgaging can fund further acquisitions or refurbishments
- Higher leverage increases returns in rising markets but reduces resilience against rate rises and valuation falls
- Conservative landlords often aim for 65% aggregate LTV, accepting slightly lower growth for greater stability
Property Mix and Diversification
Blending different property types and locations can balance yield with risk:
- Higher-yield HMOs in student cities (e.g., Leeds, Nottingham, Bristol) alongside lower-yield but more passive standard AST properties in commuter towns
- Geographic diversification across regions to reduce exposure to local market downturns or regulatory changes
- Mixing freehold houses with leasehold flats and MUFBs to spread tenant default and void risk
Upgrading Stock
- Further advances or short-term bridging finance can fund heavy refurbishments, conversions to HMOs, or creation of MUFBs from single dwellings
- Improving EPC ratings to at least C ahead of anticipated UK regulation changes can also unlock better mortgage rates and future-proof your portfolio
- Refurbishment-to-refinance strategies allow you to recycle capital efficiently
Exit and Succession Planning
- Consider when and how to de-leverage or dispose of parts of the portfolio
- Plan for retirement income—will you sell properties, live off rental income, or transfer to family members?
- Succession planning may involve incorporation if properties are currently held in personal names, or restructuring company shareholdings
Fox Davidson work closely with professional landlords, their accountants and solicitors to align finance structures with long-term business plans.
