Mortgages for Portfolio Landlords Explained
Generally lenders will consider you a portfolio landlord if you own more than 4 properties.
If you are a Portfolio Landlord, you have two main mortgage routes available to you:
- Standard Buy to Let mortgage
With a standard Buy to Let mortgage, you will have different mortgages on each of your properties.
- Portfolio Mortgage
With a Portfolio Mortgage, all of your properties will be on a single, portfolio mortgage. There will be one monthly payment and one lender.
There are pros and cons for going down both routes and we can explain these to you. Some people like the simplicity of one monthly payment and don’t mind potentially paying a higher fee. Other investors prefer the flexibility of keeping the mortgages separate and handling the different communications.
When it comes to affordability, the lender will stress test your mortgage together with your background portfolio to ensure you can afford your mortgage repayments. The sorts of things they will assess are:
- Your experience as a landlord
- All the other mortgages that you hold
- Income and cash flow from your existing property portfolio
- They can assess other income
- Your assets and liabilities
We will take time to go through this with you and ensure we choose the most appropriate option for you.

A MORTGAGE IS A LOAN SECURED AGAINST YOUR HOME. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE OR ANY OTHER DEBT SECURED ON IT.
There may be a fee for mortgage advice. The actual amount you pay will depend upon your circumstances. The fee is up to 1% but a typical fee is 0.3% of the amount borrowed.


What lenders look at for portfolio landlords
If you are a portfolio landlord, lenders will usually want to look at more than just the individual property you are mortgaging. They will often review your wider portfolio and your overall financial position before deciding what they may be willing to lend.
When assessing a portfolio landlord application, lenders may look at:
- Your full property schedule
- Rental income across the portfolio and how it stands up to stress testing
- Your existing mortgage commitments
- Your experience as a landlord
- The types of properties you own
- Your personal income, assets and wider liabilities
- Your company structure, where relevant
This is why portfolio landlord mortgages can feel more involved than standard buy to let applications. The right lender choice, and the way the case is presented, can make a significant difference.
Full property schedule
Lenders will often want a full overview of your existing properties, including values, outstanding mortgage balances, rental income and monthly mortgage payments.
Rental income and stress testing
They will usually look at how well your rental income covers your borrowing, both on the property being mortgaged and sometimes across the wider portfolio as well.
Existing mortgage commitments
Your current mortgage balances, monthly payments and overall borrowing exposure can all affect how a lender views the case.
Landlord experience
Some lenders are more comfortable if you already have a proven track record as a landlord, especially where the portfolio is larger or more complex.
Property types in the portfolio
The mix of properties you own can matter. For example, lender appetite may differ depending on whether your portfolio includes standard buy to lets, HMOs, holiday lets or other more specialist property types.
Personal income and wider liabilities
Some lenders will also want to understand your wider financial position, including employed or self employed income, other borrowing and any financial commitments outside the portfolio.
Company structure if relevant
If your properties are held personally, through a limited company or across a mixture of structures, lenders may look closely at how everything is arranged before making a decision.


Portfolio landlord mortgages through a limited company
A lot of portfolio landlords now hold some or all of their properties through an SPV or limited company structure. Mortgage options and lender criteria can differ depending on how the portfolio is held, whether there are personal guarantees, and how the wider portfolio is structured.
Some lenders are more comfortable with limited company buy to let applications than others, and the options available may depend on whether you are buying a new property, refinancing an existing one or restructuring part of your portfolio. We can help you understand which routes may be worth considering and which lenders may be more suitable for your circumstances.
Portfolio landlord remortgages
If you already own multiple buy to let properties, remortgaging can be about much more than simply replacing an existing deal. It may be an opportunity to review the wider portfolio, assess whether your current borrowing is still competitive and explore whether there is scope to raise capital where appropriate.
Some landlords want to refinance individual properties, while others want to review several mortgages at once. In some cases, a product transfer may be the simplest option. In others, a full remortgage may offer more flexibility, better terms or a more suitable long term structure.
We can help you look at:
- Refinancing part or all of your portfolio
- Raising capital where appropriate
- Product transfers versus full remortgages
- Consolidating or restructuring borrowing
- Whether your current lender criteria still suit your circumstances
This can be especially valuable where your portfolio has grown over time, your property mix has changed, or you want your borrowing arranged in a more efficient way.
