100% Mortgage Loan: How It Works

A 100% mortgage loan (commonly referred to as a 100% loan-to-value mortgage) allows you to borrow the entire cost of a property without providing a deposit. While these products were more prevalent before the global financial crisis of 2008, they are now far less common and are typically reserved for borrowers who meet stringent criteria. This guide explores how such a loan works, who might qualify, and the mechanisms available in 2025 to secure a 100 percent mortgage loan.

What Is a 100 Percent Mortgage Loan?

A 100% mortgage loan means that the lender finances the entire purchase price of a property, eliminating the need for a deposit. For example, if you wish to purchase a property valued at £1 million, a 100 percent mortgage loan would cover the entire amount, requiring no upfront payment from your side.

While appealing in concept, these loans pose a higher risk to lenders as borrowers have no equity in the property. As a result, they are rare and often associated with strict eligibility requirements, specialised products, or unique lending arrangements.

Who Qualifies for a 100 Percent Mortgage Loan?

Securing a 100% mortgage loan is generally only feasible for specific types of borrowers. These typically include:

High-Net-Worth Individuals

Lenders may extend 100% mortgages to HNWIs who demonstrate exceptional financial profiles. Even if HNWIs have significant liquidity, they may prefer not to lock funds into a property deposit to keep capital free for other investments or business opportunities.

Borrowers With Assets Under Management

Private banks or lenders often require borrowers to place significant assets under management (AUM). This arrangement serves as security for the loan and provides the lender with an additional revenue stream through investment management.

How to Secure a 100 Percent Mortgage Loan

Securing a 100 percent mortgage loan involves alternative strategies and financial arrangements. These include:

1. Using Assets Under Management

Private banks may offer 100 percent mortgage loans to clients willing to place a portion of their wealth under the bank's management. This is particularly common in Europe and among international banks. The bank then uses the managed assets as collateral for the mortgage.

Key Considerations:

• The value and type of assets placed under management will influence loan terms.

• Banks typically require a minimum AUM threshold, often starting at several million pounds.

• This approach allows borrowers to maintain liquidity while accessing full financing.

2. Lombard Loans

A Lombard loan is another effective strategy for securing a 100 percent mortgage loan. This involves pledging liquid assets such as stocks, bonds, or other securities as collateral.

How Lombard Loans Work:

• Borrowers pledge eligible assets to the lender.

• The lender provides a loan against these assets, which can be used as the deposit or to secure the full mortgage amount.

• Loan-to-value (LTV) ratios for Lombard loans depend on the quality, liquidity, and diversification of the pledged assets.

Benefits:

• Quick approval and flexibility.

• Borrowers retain ownership of the pledged assets, which can continue to appreciate or generate income.

• Typically offers lower interest rates than conventional unsecured loans.

Key Considerations for 100 Percent Mortgage Loans

1. Risk Management

Both AUM and Lombard loan structures involve placing valuable assets as collateral. These assets may be subject to market fluctuations, so working with experienced advisors to structure the loan is critical.

2. Lender Selection

Not all lenders offer 100 percent mortgage loans. Private banks and specialist lenders are the most likely to provide such facilities, and introductions through a trusted broker can significantly improve your options.

3. Terms and Conditions

Interest rates, repayment terms, and loan covenants vary widely. Understanding the nuances of these agreements ensures the loan supports your broader financial objectives.
