Property Portfolio Financing

Professional investors based overseas and private landlords such as expats based internationally with more than one buy to let property often require specialist funding to enable them to expand their property portfolio and ensure it is delivering the best returns possible.

Using separate buy to let mortgages on each individual property can not only be more expensive than alternative funding but can also restrict the ability of the investor to leverage the full extent of their borrowing power. Using portfolio financing and portfolio refinancing can help to reduce costs as well as spread the risk across a range of properties and maximise the potential for returns.

At Premier Expat Mortgages we have years of experience of working with overseas investors and landlords holding or purchasing property in the United Kingdom by helping them to fund their buy to let portfolios. Whether they have two properties or 100+ we have access to specialist lenders and private banks that can provide funding based on their entire property portfolio.

What Is Property Portfolio Financing and Refinancing And What Are The Benefits?

Landlords can secure buy to let portfolio finance on all types of property including student lets, houses with multi occupants (HMOs), professional lets, company lets, short leasehold properties, and more. There are a number of benefits to obtaining such finance including:

• One mortgage account and one direct debit.
• Allows you to borrow above the value of an individual property.
• Possibility to calculate the overall rental income percentage over your entire portfolio to support additional property purchases.
• Makes future remortgaging significantly easier if you only have one account to consider.

What Is a Portfolio Mortgage?

A portfolio mortgage is a product designed for buy-to-let landlords with multiple investment properties. It allows them to take out a single mortgage to cover all of their properties, rather than have multiple mortgages to service.

How Does a Portfolio Mortgage Work?

You can use a portfolio mortgage to hold all your buy-to-let mortgages under one mortgage umbrella.

It’s treated as one account, so instead of having separate lenders for each mortgage or property, the whole portfolio is managed by one lender with one monthly payment and one statement.

The portfolio is often registered as a limited company, with costs and finances treated as they would be with any other business.

From a lender’s point of view, a landlord would typically need a minimum of four properties to be eligible for a portfolio mortgage.

How Many Buy-to-Let Mortgages Can I Have?

As long as you meet the criteria, there’s no fixed limit to the number of buy-to-let mortgages you can have.

Different lenders may have their own rules about the maximum number of loans they can advance to an individual, but there are many portfolio mortgage lenders in the market who want to help you grow your investment.

If you’re looking to grow your buy-to-let investment portfolio, it’s worth getting your paperwork in order and keeping an up-to-date spreadsheet of your property portfolio, so that all the information is readily available when a lender asks for it.

How Can I Get Buy-to-Let Mortgages for Multiple Properties?

If you’re looking to increase your buy-to-let portfolio lending, a conversation with an expat mortgage adviser will help you understand the best way to take on multiple buy-to-lets, taking your full circumstances into account.

One of the options available to you will be purchasing buy-to-let properties using a limited company rather than in your own name.

Should I Get a Portfolio Mortgage Through a Limited Company?

In some circumstances, it can be beneficial for tax reasons for buy-to-let investors to finance multiple buy-to-let mortgages using a limited company.

There are two types of limited company structure worth knowing about: a trading company, or a special purpose vehicle (SPV). Our UK Limited Company Mortgages page covers this structure in full detail.

The most common way for buy-to-let investors to buy through a limited company is via an SPV. There are considerably more lenders in this part of the market than there used to be, with genuine portfolio lending options for both individuals and companies.

As a result, buy-to-let mortgages for limited companies are now often available at similar rates to those for individuals holding multiple buy-to-let mortgages in their personal name.

Buy-to-let mortgage lenders for limited companies will often apply a lower minimum rental stress test than they do for individuals who are higher-rate taxpayers, reflecting the tax advantages associated with buying and managing property through a limited company.

How Many Buy-to-Let Mortgages Can I Get Using a Limited Company?

There’s no fixed limit to the number of buy-to-let mortgages you can hold within a limited company structure. However, the same principles apply when a lender assesses your entire portfolio as part of an application, and some lenders set a limit on the exposure they’re willing to take on for any one company, restricting the total number of mortgages or properties they’ll finance.

Which Lenders Offer Portfolio Mortgages?

Portfolio mortgages are offered by a variety of specialist lenders and private banks, and each has its own lending criteria that must be met by the applicant. A select number of high street lenders can also consider portfolio mortgage applications in certain circumstances, though the majority of genuine portfolio lending sits with lenders built specifically for this kind of borrower.

What Underwriters Actually Look At

Beyond your personal and rental income, portfolio underwriters consider ongoing credit commitments, the speed at which your portfolio has been built and its capital appreciation to date, tenant quality and occupancy levels across your existing properties, whether you use letting or management agents, and your overall portfolio strategy and future funding requirements. Presenting this picture clearly and completely from the outset genuinely speeds up the assessment process considerably.

Financing an Existing Portfolio vs Building a New One

If you already hold several properties and are looking to consolidate them under a single facility, our approach starts with a full review of your existing mortgages, rates, and terms to understand whether refinancing genuinely improves your position. If you’re building a new portfolio from a smaller starting point, we’ll help you understand realistically when you’ll cross the four-property threshold that typically triggers portfolio-level assessment, and how to structure your early purchases with that eventual scale in mind.
