100% Mortgage Guide

What is a 100% Mortgage?

A 100% mortgage is a type of home loan that allows you to borrow the full purchase price of a property, meaning you don’t need to put down a deposit.

Traditionally, most lenders require a deposit of at least 5–10%, but with 100% mortgages, this hurdle is removed, helping first-time buyers or those struggling to save get on the property ladder faster.

Who Are 100% Mortgages For?

100% mortgages are suitable for people who:

  • Have no deposit saved

  • Have a strong and stable income

  • Have a good credit history

  • May have family support (e.g. parents willing to help)

  • Are first-time buyers or renters with a clean payment history

How Do 100% Mortgages Work?

100% mortgages usually require additional support or security for the lender. This could be through a guarantor, a savings lock from a family member, or proof of strong financial stability.

Here are the main types:

Type of 100% MortgageHow it Works
Guarantor MortgageA family member guarantees the loan, agreeing to cover repayments if needed
Family Security MortgageFamily member puts savings in a linked account as security
Rental Track Record SchemeLenders use proof of rental payments instead of deposit (e.g. Skipton)

What Are the Requirements?

Although no deposit is needed, lenders will still assess your ability to repay the mortgage.

RequirementWhat Lenders Look For
Credit ScoreUsually good to excellent (check via Experian or Equifax)
Income StabilitySteady income with at least 6–12 months of employment
Affordability ChecksCan you afford repayments with your current income & expenses?
Proof of Rental PaymentsFor “track record” mortgages – consistent rent paid on time
Family Support (if required)Willingness to act as guarantor or provide savings as security
