What are large loan buy-to-let mortgages?

A large loan buy-to-let mortgage is a specialist product designed for property investors looking to borrow significant amounts.

What qualifies as a large loan amount differs depending on the lender. Certain lenders label buy-to-let loans exceeding £500,000 as large loans, while other lenders set the threshold higher at over £1 million.

These mortgages cater to investors who want to:

  • Purchase multiple rental properties within a single financing deal rather than have one mortgage for each of them.
  • Acquire higher value investments like Houses in Multiple Occupation (HMOs), multi-unit blocks, or commercial premises.
  • Release equity from existing portfolios to fund further property acquisitions and growth.
  • Consolidate financing for a large real estate portfolio under one efficient mortgage.

By streamlining borrowing into one larger mortgage loan, experienced landlords can take their property business to the next level more quickly. Large loan buy-to-let products enable raising substantial capital tailored to property buy-to-let investment strategies faster.

Criteria for large loan buy-to-let mortgages

Extensive experience in owning and managing rental properties can be a plus, but it is not a mandatory requirement to be approved for larger buy-to-let loans over £1 million.

Some private lenders will consider first-time buyers. Lenders want confidence that you can handle the higher responsibilities that come with large-scale financing and portfolio management.

Typical applicant profile criteria for large loan products include the following:

  • First-time buyers are accepted for more flexible and niched lenders. Being an experienced landlord is a plus, but it is not mandatory
  • Minimum age of 21 years old
  • Minimum 125% of monthly mortgage payments when using a stressed interest rate.
  • Deposits of at least 25%
  • Most specialists lenders will want to take a look at your current situation and propose a deal that will align with your goals


First-time landlords or those with only 1-2 existing properties can still meet the requirements for a large buy-to-let mortgage loan.

Lenders will want to assess the likely rental income in addition to looking at the personal finance situation of a client.

How much can be borrowed?

Loan sizes available for large buy-to-let mortgages are available up to £5 million, although some lenders may be able to offer higher borrowing.

The maximum amount you can access will depend on factors like:

  • The level of equity/deposits you have available
  • Total current value of your property portfolio assets
  • Expected annual rental income across all properties involved in this loan
  • Your existing debts, liabilities, and financial commitments
  • Your overall credit profile, income, and financial standing

The last two items will have a heavy weight on the lender’s decision, especially if you will use top slicing (more details ahead).

Lenders restrict lending to a percentage of the portfolio value and rental income to control risk, typically maxing out at 75% loan-to-value.

What is top slicing for large loans?

Top slicing can be used in two ways.

An additional property within a portfolio can be used as additional security to access a larger loan amount.

For example, a landlord may have a portfolio worth £2 million with £500,000 of equity. Normally this would limit borrowing to £1.5 million at 75% LTV. Top slicing can be used by offering an additional property with equity for security, perhaps valued at £500,000, which enables for a larger loan to be offered on the primary security.

In this scenario, an additional borrowing of £200,000 (for example) could be borrowed, taking the maximum loan to £1.7m. So the enhanced leverage on one asset unlocks more total financing. Top slicing can help landlords with substantial portfolios but limited free equity access extra capital.

Top slicing can also utilise a landlord’s personal income to access higher leverage on a buy-to-let purchase.

For example, a landlord with £150,000 in annual salary income is looking to purchase a buy-to-let property for £500,000. Based solely on the property’s rental income and if in a lower yielding area like London, a lender may limit lending to £250,000 at 50% LTV. But by top slicing utilising the disposable income from the clients’ £150,000 salary income, the landlord could borrow £325,000 instead, or 75% LTV. This demonstrates greater affordability, allowing higher leverage.

For high-net-worth individuals, top-slicing personal income gives more mortgage borrowing power on buy-to-let acquisitions beyond standard lending limits.
