Mortgage Deposit and Loan-to-Value Explained<\/h2>\n\n

Most UK home buyers use a combination of their own deposit and a mortgage to purchase a property. The relationship between these amounts is known as the loan-to-value ratio<\/strong>, usually shortened to LTV<\/strong>.<\/p>\n\n

Your LTV can affect the mortgage products available, but it does not replace the lender\u2019s affordability, credit and property checks.<\/p>\n\n

\nSimple answer:<\/strong> Your deposit is the part of the property price you provide. Your mortgage covers the remaining amount accepted by the lender. LTV shows the mortgage as a percentage of the property\u2019s value.\n<\/blockquote>\n\n<\/section>\n\n
\n

What Is a Mortgage Deposit?<\/h2>\n\n

A mortgage deposit is the buyer\u2019s contribution towards the property purchase. It normally comes from savings, existing property equity or another source accepted by the mortgage lender and conveyancer.<\/p>\n\n

Example<\/h3>\n\n

Property price: \u00a3300,000\nBuyer\u2019s deposit: \u00a330,000\nMortgage required: \u00a3270,000<\/p>\n\n

The buyer provides 10% of the price, while the mortgage lender provides the remaining 90%.<\/p>\n\n

The deposit is only one part of the money buyers need. Stamp Duty or Land Transaction Tax, conveyancing fees, surveys, mortgage fees and moving costs may need to be funded separately.<\/p>\n\n<\/section>\n\n

\n

What Does Loan-to-Value Mean?<\/h2>\n\n

Loan-to-value compares the mortgage amount with the lender\u2019s accepted property value.<\/p>\n\n

LTV formula:<\/strong><\/p>\n\n

Mortgage amount \u00f7 property value \u00d7 100 = LTV percentage<\/p>\n\n

Example<\/h3>\n\n

Mortgage required: \u00a3270,000\nProperty value: \u00a3300,000<\/p>\n\n

\u00a3270,000 \u00f7 \u00a3300,000 \u00d7 100 = 90% LTV<\/strong><\/p>\n\n

The remaining 10% is normally provided by the buyer as the mortgage deposit.<\/p>\n\n<\/section>\n\n

Lenders commonly group mortgage products into LTV bands. Reaching a lower band may change the range of products available, but the result depends on the lender and current mortgage market.<\/p>\n\n<\/section>\n\n

\n

How Much Deposit Do UK Buyers Usually Need?<\/h2>\n\n

Many residential mortgage products require a deposit of at least 5% to 10% of the property value. The amount required depends on the buyer, property and lender.<\/p>\n\n\n\n\n\n\n\n\n\n\n
Mortgage LTV<\/th>\nBuyer\u2019s Deposit<\/th>\nDeposit on a \u00a3250,000 Property<\/th>\n<\/tr>\n<\/thead>\n

75% LTV<\/td>\n25%<\/td>\n\u00a362,500<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n

A particular property may require a larger deposit because of its construction, condition, location, lease terms, new-build status or the lender\u2019s valuation.<\/p>\n\n

\nImportant:<\/strong> A mortgage advertised as requiring a 5% deposit does not mean every buyer or property will qualify for that mortgage.\n<\/blockquote>\n\n<\/section>\n\n
\n

How a Larger Deposit Changes the Mortgage<\/h2>\n\n

A larger deposit reduces both the mortgage amount and the LTV. This may affect:<\/p>\n\n

    \n
  • the mortgage products available;<\/li>\n
  • the interest rate offered;<\/li>\n
  • the monthly repayment;<\/li>\n
  • the total interest charged;<\/li>\n
  • the lender\u2019s property criteria; and<\/li>\n
  • the buyer\u2019s exposure to negative equity.<\/li>\n<\/ul>\n\n

    Example<\/h3>\n\n

    Two buyers want to purchase identical \u00a3300,000 properties.<\/p>\n\n\n\n\n\n\n\n\n
    <\/th>\nBuyer A<\/th>\nBuyer B<\/th>\n<\/tr>\n<\/thead>\n
    Deposit<\/strong><\/td>\n\u00a315,000<\/td>\n\u00a360,000<\/td>\n<\/tr>\n

    LTV<\/strong><\/td>\n95%<\/td>\n80%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n

    Buyer B needs to borrow \u00a345,000 less. However, mortgage approval still depends on affordability, credit checks and the property.<\/p>\n\n<\/section>\n\n

    \n

    What Is a 95% LTV Mortgage?<\/h2>\n\n

    A 95% LTV mortgage allows an eligible buyer to borrow up to 95% of the lender\u2019s accepted property value and provide the remaining 5% as a deposit.<\/p>\n\n

    Example<\/h3>\n\n

    Property value: \u00a3240,000\n5% deposit: \u00a312,000\n95% mortgage: \u00a3228,000<\/p>\n\n

    The UK Government introduced a permanent Mortgage Guarantee Scheme<\/strong> in July 2025 to support the availability of mortgages between 91% and 95% LTV through participating lenders.<\/p>\n\n

    The scheme can support eligible first-time buyers and home movers, but buyers must still pass the lender\u2019s normal affordability, credit and property checks.<\/p>\n\n

    \nWhat the guarantee means:<\/strong> The government guarantee protects the participating lender against part of a possible loss. It does not pay the buyer\u2019s deposit, guarantee approval or protect the buyer from missed mortgage payments.\n<\/blockquote>\n\n

    Not every 95% mortgage is part of the government scheme, and not every lender participates.<\/p>\n\n<\/section>\n\n

    \n

    Can You Get a Mortgage Without a Deposit?<\/h2>\n\n

    Some lenders may offer specialist 100% LTV or no-deposit mortgages under limited criteria. These may depend on factors such as rental-payment history, family support, savings held as security or a guarantor arrangement.<\/p>\n\n

    These products are different from the Government Mortgage Guarantee Scheme, which supports lending between 91% and 95% LTV.<\/p>\n\n

    No-deposit mortgages generally involve a higher lending risk because the buyer begins with little or no equity in the property. Availability and eligibility can be limited.<\/p>\n\n<\/section>\n\n

    \n

    How the Mortgage Valuation Affects Your Deposit<\/h2>\n\n

    The estate agent\u2019s asking price and your accepted offer do not decide how much the mortgage lender believes the property is worth.<\/p>\n\n

    The lender carries out a mortgage valuation<\/strong> before confirming the amount it is prepared to lend.<\/p>\n\n

    If the lender values the property below the agreed purchase price, this is commonly called a down valuation<\/strong>.<\/p>\n\n

    Down-Valuation Example<\/h3>\n\n

    Agreed purchase price: \u00a3300,000\nBuyer expected a 90% mortgage: \u00a3270,000\nExpected deposit: \u00a330,000<\/p>\n\n

    The lender values the property at \u00a3280,000. If the lender will provide a maximum 90% LTV mortgage based on that valuation:<\/p>\n\n

    \u00a3280,000 \u00d7 90% = \u00a3252,000 mortgage<\/strong><\/p>\n\n

    If the purchase price remains \u00a3300,000, the buyer would need:<\/p>\n\n

    \u00a3300,000 \u2212 \u00a3252,000 = \u00a348,000<\/strong><\/p>\n\n

    The deposit requirement has therefore increased from \u00a330,000 to \u00a348,000.<\/p>\n\n

    \nHidden deposit risk:<\/strong> The lender\u2019s valuation can change the mortgage amount even when the seller has already accepted your offer.\n<\/blockquote>\n\n<\/section>\n\n
    \n

    Mortgage Deposit vs Exchange Deposit<\/h2>\n\n

    The terms mortgage deposit<\/strong> and exchange deposit<\/strong> are often confused, but they describe different parts of the purchase.<\/p>\n\n\n\n\n\n\n\n\n
    Deposit Type<\/th>\nWhat It Means<\/th>\n<\/tr>\n<\/thead>\n
    Mortgage deposit<\/strong><\/td>\nThe buyer\u2019s total financial contribution towards the property price.<\/td>\n<\/tr>\n
    Exchange deposit<\/strong><\/td>\nThe contractual deposit paid through the conveyancers when contracts are exchanged.<\/td>\n<\/tr>\n
    Reservation fee<\/strong><\/td>\nA separate payment sometimes used for a new build or auction purchase.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n

    The traditional exchange deposit is 10% of the purchase price. A buyer using a 95% mortgage may only have a 5% mortgage deposit, so the conveyancers may need to agree a reduced exchange deposit with the seller.<\/p>\n\n

    Paying a reduced amount at exchange may not necessarily limit the buyer\u2019s contractual responsibility to that lower amount if the buyer later fails to complete. The signed contract determines the position.<\/p>\n\n<\/section>\n\n

    \n

    Where Can a Mortgage Deposit Come From?<\/h2>\n\n

    A deposit can come from several sources, subject to the lender\u2019s requirements and source-of-funds checks.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
    Deposit Source<\/th>\nInformation Commonly Required<\/th>\n<\/tr>\n<\/thead>\n

    Gift from family<\/strong><\/td>\nA gifted-deposit letter, donor identification and evidence showing the source of the funds.<\/td>\n<\/tr>\n
    Inheritance<\/strong><\/td>\nProbate, estate or solicitor documentation and evidence of receipt.<\/td>\n<\/tr>\n

    Deposit money appearing suddenly in an account without a clear explanation may lead to further questions from the lender or conveyancer.<\/p>\n\n<\/section>\n\n

    \n

    How Does a Gifted Deposit Work?<\/h2>\n\n

    A gifted deposit is money provided by another person, commonly a parent or close family member, to help fund the purchase.<\/p>\n\n

    The mortgage lender and conveyancer commonly need confirmation that:<\/p>\n\n
